NASA successfully kicked off its historic Artemis 2 mission around the Moon on Wednesday, a pitch-perfect rocket launch that saw the agency’s towering Space Launch System and Orion capsule carry humans to space for the first time.
Besides being the first time we’ve sent humans to our celestial neighbor in over half a century, the mission’s daring crew of four also includes the first Black person and first woman to visit the Moon.
A third passenger, though, is raising hackles online. The agency’s decision to bring Canadian Space Agency astronaut and former North American Aerospace Defense Command fighter jet pilot Jeremy Hansen seems to have president Donald Trump’s supporters in a tizzy.
“Why are we letting a Canadian go to our Moon?” one X account wrote in a tweet that was liked and reshared thousands of times.
While the author likely meant the missive in jest, a brief glance at other colorful commentary proliferating on Elon Musk’s social media platform paints an unflattering picture of the way some Americans view the historic act of international collaboration.
“The US is sending a Canadian to the Moon on Wednesday,” another user wrote. “You would never guess that, from how they run their mouths, and how their stupid Prime Minister sucks up to China, but that’s okay. We are a great and generous people.”
It’s the kind of xenophobic isolationism the Trump administration has become known for. Some took to the platform to further its highly controversial stance that Canada should be annexed as the so-called “51st state.” Trump has repeatedly used inflammatory rhetoric to antagonize the United States’ northern neighbor and once closest ally.
“America is sending a Canadian to the moon because the American 1,000 Year Empire already controls Canada,” one account wrote.
“The US has a flag on the Moon,” another teased. “You don’t, Canadian bacon.”
Other commentators took a more lighthearted tone, poking fun at the way the media treated the subject.
“Wow, we really did it,” YouTuber and space enthusiast TJ Cooney tweeted. “Three humans and one Canadian going to the Moon.”
“It’s so funny that they keep saying first Canadian to go to the Moon in the same breath as the first Black man and the first woman,” Semafor‘s Josh Billinson wrote. “Sure, it’s true, but it’s not really the same thing!”
“The structural barrier to Canadians going to the Moon last time was not having a space agency!” he added.
Indeed, the Canadian Space Agency was established in 1990, several decades after NASA’s Apollo missions wrapped up. It has been been fostering a tight partnership with its American counterpart ever since, as exemplified by the Canadarm, the robotic arm that’s supported US Space Shuttle missions for 30 years. The agency’s followup Canadarm2, currently attached to the exterior of the International Space Station, has proven invaluable for orbital operations for the last 25 years.
Fortunately, the heated rhetoric on social media has likely flown far over the head of Hansen, who also wasn’t above playing into Canadian stereotypes during his preparations for the mission. He made sure to bring a piece of home while hundreds of thousands of miles away from home: maple syrup and maple cream cookies.
“I just kept saying to them yesterday, I really like it up here,” Hansen said in comments to the media on Friday, while surrounded by the cramped interior of NASA’s Orion spacecraft and his three American crewmates. “I wish I could’ve gotten here sooner.”
Acetyl-L-carnitine (ALC) is a form of L-carnitine, an amino acid that is found in nearly all cells of the body. L-carnitine plays a critical role in producing energy from long-chain fatty acids. Simply put, it converts fat into energy. In addition, it is believed to increase the activity of certain nerve cells in the central nervous system.
L-carnitine serves an important role in energy production and metabolism by importing a substance called acetyl coenzyme A (acetyl-CoA) into the mitochondria (power bank of the cells). Acetyl-CoA is like a coin that kickstarts cellular machinery, making it a key player in energy synthesis.
Having enough L-carnitine is important for muscle, heart, and brain health. Moreover, L-carnitine improves acetylcholine (neurotransmitter) levels in the brain, which may help improve memory, prevent neuronal aging, and treat weakness due to poor acetylcholine levels at the neuromuscular junctions in the body.
What are rich sources of acetyl-L-carnitine?
Although many people take supplements containing ALC for its purported benefits, there isn’t enough scientific evidence to back these claims.
Animal-based foods are good sources of carnitine.
Beef: 81 milligrams per 3 ounces (85 grams)
Pork: 24 milligrams per 3 ounces (85 grams)
Fish: 5 milligrams per 3 ounces (85 grams)
Chicken: 3 milligrams per 3 ounces (85 grams)
Milk: 8 milligrams per 8 ounces (227 mL)
Although most diets contain enough carnitine, the human body can make its own supply through enzymatic action on the amino acid lysine.
What are the uses and benefits of acetyl-L-carnitine?
Diabetic neuropathy: Taking ALC seems to improve symptoms in people with nerve pain caused by diabetes by improving nerve health and reinforcing nerve cell structure.
Alzheimer’s disease: L-carnitine has shown improvements or slower declines in the mental ability of people with Alzheimer’s disease. ALC may slow the rate of disease progression and improve memory and some measures of mental function and behavior. It may also help with other types of dementia.
Alcoholism: ALC may help reduce cravings in people suffering from alcoholism. Taken orally or intravenously, ALC may reduce cravings and improve symptoms of alcohol withdrawal.
Depression: ALC treatment reduces symptoms of depression in older people. Taking 1-4 grams of ALC per day may improve mood and reduce depression in some people. It seems to work better in elderly people and when taken in higher amounts.
Fragile X syndrome: L-carnitine affects certain behaviors in boys with fragile X syndrome such as their social skills and hyperactivity.
Male infertility: Taking ALC orally, usually along with L-carnitine and other supplements, seems to increase sperm count and sperm mobility in men with fertility problems.
Peyronie’s disease: Some studies have shown that men who took ALC daily for 3 months had less pain and curving of the penis.
Potential benefits of ashwagandha include better athletic performance and sleep. Some research suggests this herb may help people with conditions like anxiety and infertility, but stronger studies are needed.
Ashwagandha is one of the most important herbs in Ayurveda, which is a traditional form of alternative medicine based on Indian principles of natural healing.
People have used ashwagandha for thousands of years to relieve stress, increase energy levels, and improve concentration.
“Ashwagandha” is Sanskrit for “smell of the horse,” which refers to both the herb’s scent and its potential ability to increase strength.
Its botanical name is Withania somnifera, and it’s also known by several other names, including “Indian ginseng” and “winter cherry.”
The ashwagandha plant is a small shrub with yellow flowers that’s native to India and Southeast Asia. People use extracts or powder from the plant’s root or leaves to treat a variety of conditions, including anxiety and fertility issues.
Here are 8 potential benefits of ashwagandha, based on research.
May help reduce stress and anxiety
Ashwagandha is perhaps best known for its ability to reduce stress. It’s classified as an adaptogen, a substance that helps the body cope with stress.
Ashwagandha may help control mediators of stress, including heat shock proteins (Hsp70), cortisol, and stress-activated c-Jun N-terminal protein kinase (JNK-1).
It also reduces the activity of the hypothalamic-pituitary-adrenal (HPA) axis, a system in your body that regulates the stress response.
Research suggests Ashwagandha supplements may help relieve stress and anxiety.
In a small study with 58 participants, those who took 250 or 600 mg of ashwagandha extract for 8 weeks had significantly reduced perceived stress and levels of the stress hormone cortisol compared with those who took a placebo.
Those who took the ashwagandha supplements also saw improvements in sleep quality compared with the placebo group.
Another study in 60 people found that those who took 240 mg of ashwagandha extract per day for 60 days had significant reductions in anxiety compared with those who received a placebo treatment.
Thus, early research suggests ashwagandha may be a helpful supplement for stress and anxiety.
However, a 2021 review of studies concluded that there’s not enough evidence to form a consensus on the most appropriate dosage and form of ashwagandha for treating stress-related neuropsychiatric disorders such as anxiety.
May benefit athletic performance
Research has shown that ashwagandha may have beneficial effects on athletic performance and may be a worthwhile supplement for athletes.
One analysis of research included 12 studies in people who took ashwagandha doses between 120 mg and 1,250 mg per day. The results suggest the herb may enhance physical performance, including strength and oxygen use during exercise.
Another analysis that looked at five studies found that taking ashwagandha significantly enhanced maximum oxygen consumption (VO2 max) in healthy adults and athletes.
VO2 max is the maximum amount of oxygen a person can use during intense activity. It’s a measurement of heart and lung fitness.
Having optimal VO2 max is important for athletes and nonathletes alike. Low VO2 max is associated with increased mortality risk, while higher VO2 max is associated with a lower risk of heart disease.
Additionally, ashwagandha may help increase muscle strength.
In a 2015 study, male participants who took 600 mg of ashwagandha per day and participated in resistance training for 8 weeks had significantly greater gains in muscle strength and size compared with a placebo group.
May reduce symptoms of some mental health conditions
Some evidence suggests that ashwagandha may help reduce symptoms of other mental health conditions, including depression, in certain populations.
In one study, researchers looked at the effects of ashwagandha in 66 people with schizophrenia who were experiencing depression and anxiety.
They found that participants who took 1,000 mg of ashwagandha extract daily for 12 weeks had greater reductions in depression and anxiety than those who took a placebo.
Limited research from 2013 also suggests that ashwagandha may help improve cognitive impairment in people with bipolar disorder.
A 2021 review concluded that ashwaghanda may help manage depression, anxiety, insomnia, and other mental health-related and neurological issues.
However, more research is needed into all these uses.
May help boost testosterone and increase fertility in men
Ashwagandha supplements have been shown in some studies to benefit male fertility and increase testosterone levels.
In one study, 43 males aged 40–70 with overweight and mild fatigue took tablets containing ashwagandha extract or a placebo daily for 8 weeks.
The treatment was associated with an 18% greater increase in DHEA-S, a sex hormone involved in testosterone production. Participants who took the herb also had a 14.7% greater increase in testosterone than those who took the placebo.
Additionally, a review of four studies found that ashwagandha treatment significantly increased sperm concentration, semen volume, and sperm motility in males with low sperm count.
It also increased sperm concentration and motility in males with normal sperm count.
However, more studies are needed.
May reduce blood sugar levels
Limited evidence suggests that ashwagandha may have some benefits for people with diabetes or high blood sugar levels.
A review of 24 studies, including 5 clinical studies in people with diabetes, found that treatment with ashwagandha significantly reduced blood sugar, hemoglobin A1c (HbA1c), insulin, blood lipids, and oxidative stress markers.
The reason may be that certain compounds within ashwagandha — including one called withaferin A (WA) — have powerful antidiabetic activity and may help stimulate cells to take in glucose from the bloodstream.
However, research is limited at this time, and more well-designed studies are needed.
May reduce inflammation
Ashwagandha contains compounds, including WA, that may help reduce inflammation in the body.
Animal studies have shown that WA may also help reduce levels of inflammatory proteins such as interleukin-10 (IL-10), and there’s some evidence ashwagandha may help reduce inflammatory markers in humans too.
In a 2021 study, researchers gave people with COVID-19 an Ayurvedic drug containing 0.5 grams of ashwagandha and other herbs twice per day for 7 days. This reduced participants’ levels of inflammatory markers CRP, IL-6, and TNF-α compared with a placebo.
The treatment formulation also contained:
1 gram of giloy ghanvati (Tinospora cordifolia)
2 grams of swasari ras (a traditional herbo-mineral formulation)
0.5 grams of tulsi ghanvati (Ocimum sanctum)
However, research on ashwagandha’s potential effects on inflammation remain limited.
May improve brain function, including memory
Taking ashwagandha may benefit cognitive function.
One review of five clinical studies found early evidence that ashwagandha could improve cognitive functioning in certain populations, including older adults with mild cognitive impairment and people with schizophrenia.
Cognitive functions it may benefit included:
executive functioning
attention
reaction time
performance on cognitive tasks
A study in 50 adults showed that taking 600 mg of ashwagandha extract per day for 8 weeks led to significant improvements in the following measures compared with taking a placebo:
immediate and general memory
attention
information-processing speed
The researchers noted that compounds found in ashwagandha, including WA, have antioxidant effects in the brain, which may benefit cognitive health.
However, more research is needed before experts can draw strong conclusions.
May help improve sleep
Many people take ashwagandha to promote restful sleep, and some evidence suggests it may help with sleep issues.
For example, a study in 50 adults ages 65–80 found that taking 600 mg of ashwagandha root per day for 12 weeks significantly improved sleep quality and mental alertness upon waking compared with a placebo treatment.
Additionally, one review of five high quality studies found that ashwagandha appeared to:
have a small but significant positive effect on overall sleep quality
reduce anxiety levels
help people feel more alert when they woke up
The results were more pronounced in people with insomnia and in those who took more than 600 mg daily for 8 weeks or longer.
Safety and side effects
Ashwagandha is likely safe for most people when used for up to 3 months, although its long-term effects are unknown.
However, ashwagandha may not be safe if a person:
is pregnant, as high doses may lead to pregnancy loss
is breastfeeding
has hormone-sensitive prostate cancer
is taking certain medications, such as benzodiazepines, anticonvulsants, or barbiturates
is about to have surgery
has an autoimmune or thyroid disorder
has liver problems
Some people using ashwagandha supplements have reported the following adverse effectsTrusted Source:
upper gastrointestinal discomfort
drowsiness
diarrhea
vomiting
Ashwagandha’s effects may not be immediate, and you may have to take it for several months before noticing its effects.
Always speak with a doctor to ensure ashwagandha or other supplements are safe for you to use.
Dosage
Dosing recommendations for ashwagandha vary. For example, research has shown doses ranging from 250–1,250 mg per day to to be effective for different conditions. Consult a healthcare professional if you have questions regarding ashwagandha dosing.
You can take ashwagandha in many ways, in either a single dose or multiple doses per day. And you can take it either with meals or on an empty stomach.

Broadway is a major east-west thoroughfare in the city of Vancouver, British Columbia, Canada. In Vancouver’s numbered avenue grid system, it runs in place of a 9th Avenue, between 8th and 10th. The street has six lanes for most of its course. Portions of the street carry the British Columbia Highway 7 designation.
The route begins as “West Broadway” at the intersection of Wallace Crescent and 8th Avenue, in the affluent residential neighbourhood of West Point Grey, a few kilometres east of the University of British Columbia (UBC). Past Alma Street, Broadway takes over from 10th Avenue as one of Vancouver’s major thoroughfares, as it enters Greek West Broadway (or Greektown) section of Vancouver’s Kitsilano district. East of here are several blocks of generally trendy, upscale shops interspersed with low-rise apartment blocks and small supermarkets. The surrounding neighbourhoods generally consist of large, older homes dating from the early twentieth century, many of which have been subdivided into rental suites.
As Broadway approaches Arbutus Street, the commercial establishments become larger before transitioning into a mix of small to mid-size apartment blocks. East of Burrard Street, the apartment blocks get progressively taller, and commercial establishments larger and busier. Between Burrard and Main Street, Broadway can be considerably congested by vehicular traffic. Past Granville Street, Broadway yields completely to medium-to-large commercial structures and high-rise apartments and condominiums. Between Cambie and Main, the commercial establishments become smaller and somewhat more downscale.
At Ontario Street, two blocks west of Main, the route becomes “East Broadway.” After bisecting Main and Kingsway, traffic on Broadway eases somewhat, and the character returns to a mix of small-to-medium apartment buildings and commercial establishments, interspersed with older homes – all considerably less affluent than those to the west. At Commercial Drive, Broadway passes by the Commercial–Broadway SkyTrain Station. Past here for several blocks, the neighbourhood consists predominantly of older residential homes.
As Broadway travels east of Renfrew Street, the neighbourhood once again becomes mixed, with older homes to the north and larger industrial, commercial, and warehouse establishments to the south. Broadway finally ends at Cassiar Street, just short of the Vancouver-Burnaby boundary, where it becomes the Lougheed Highway.
Broadway was created at the turn of the 20th century, along with other gridded roads south of False Creek, to meet the needs of an expanding population in Vancouver. The name of the route was changed from 9th Avenue to Broadway in 1909, at the behest of merchants around Main Street (at that time the hub of Vancouver commerce), who felt that it bestowed a more cosmopolitan air. Commercial establishments originally spread out around the intersections of Cambie and Main Streets, while the character of the rest of the route remained predominantly single-family dwellings.
By the 1970s, the length of Broadway had become a major arterial route in Vancouver, conveying commuters from downtown to the neighbourhoods of the west and east sides. With the growth of UBC and the expansion of the Vancouver General Hospital (one block south of Broadway between approximately Oak and Cambie), traffic demands accelerated. In the 1990s, the agency then responsible for public transit in Greater Vancouver — BC Transit — introduced an express bus route, the 99 B-Line, to help reduce congestion. The Vancouver transportation plan for Broadway notes that congestion is such that the bus service is at capacity, and will not be eased until a new rapid transit line is built paralleling the street. It is anticipated that the SkyTrain’s Millennium Line will be extended to Central Broadway by 2021; the extension is expected to connect with Canada Line at Broadway-City Hall Station, at the intersection of Broadway and Cambie Street.
Preservationists lamented last year when another treasure of L.A.’s midcentury modern architecture vanished, this time with little warning. Situated on one of Brentwood’s most desirable streets, the Zimmerman House was sadly demolished.
Recently, outrage has risen on the Internet as architecture fans and Angelenos who love the city’s history have discovered that Chris Pratt and Katherine Schwarzenegger had the architectural marvel and beloved mid-century estate demolished.
Twitter users said, “It’s sad to see icons of modernism needlessly destroyed by insensitive McMansion seekers.” and “truly the worst Chris.”
The Los Angeles Conservancy posted a demolition alert on January 11 of this year, which said, “We recently learned about the proposed demolition of this 1950 Modernist residence at 400 North Carmelina Avenue in Brentwood. Designed by Emiel Becsky and working within architect Craig Ellwood’s office, he created a one-story, nearly 3,000 sq. ft. residence that appears to be highly intact and a noteworthy example of Modernist design from this era. The City’s SurveyLA program identified it as potentially historic, yet no protections are currently afforded.”
Martin and Eva Zimmerman commissioned the architect Ellwood to build their home in 1949, which was completed in 1950. The home was a showplace featured in architectural magazines; the estate’s outdoor spaces were curated by landscape designer Garrett Eckbo.
The estate was sold in 1968 and then again in 1975, when it fetched $205,000 when it was purchased by screenwriter and showrunner Sam Rolfe and his wife, Hilda. Hilda Rolfe said that her husband “created 13 in all, including Have Gun – Will Travel, The Man From U.N.C.L.E., and The Manhunter.” as quoted by The New York Times.
The home was sold in an off-market sale for $12.5 million after Hilda Newman-Rolfe died in 2022. The secret buyers were Pratt and Schwarzenegger, who promptly razed the midcentury structure to construct a new mansion. According to the Robb Report, the permits for the new mansion stated that the architect, Ken Ungar, famous for the modern farmhouse-style mansions that are going up all over the city, is designing their new home.
The couple likely chose to destroy the home for the simple reason that the now vacant lot is close to the estate of Katherine Schwartzeneggar’s mother, Maria Shriver, on North Carmelina Drive. Pratt and Schwarzenegger are still living in their mansion in the Pacific Palisades until their new mansion is completed.
Omega-3 fatty acids have been linked to many health benefits. In particular, they may help promote brain and heart health, reduce inflammation, and protect against several chronic conditions.
Omega-3 fatty acids are incredibly important. They have many powerful health benefits for your body and brain. In fact, few nutrients have been studied as thoroughly as omega-3 fatty acids.
Here are 17 health benefits of omega-3 fatty acids that are supported by science.
May benefit depression and anxiety
Depression is one of the most common mental disorders in the world. Symptoms often include sadness, lethargy, and a general loss of interest in life.
Anxiety, another common disorder, is characterized by feelings of fear, panic, and restlessness.
Research suggests people who consume omega-3s regularly are less likely to have depression. What’s more, studies in people with depression and anxiety suggest that omega-3 supplements may improve symptoms.
There are three types of omega-3 fatty acids: alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Of the three, EPA appears to be the most beneficial for depression.
May improve eye health
DHA, a type of omega-3, is a major structural component of the retina of your eye. When you don’t get enough DHA, vision problems may arise.
Interestingly, getting enough omega-3 is also linked to a reduced risk of macular degeneration, one of the leading causes of permanent eye damage and blindness worldwide.
Could promote brain health during pregnancy and early life
Omega-3s are crucial for brain growth and development in infants.
Getting enough omega-3s during pregnancy is associated with numerous benefits for your child, including:
improved cognitive development
better communication and social skills
fewer behavioral problems
decreased risk of developmental delay
However, more research is needed, as some studies have produced mixed results.
May improve risk factors for heart disease
Heart attacks and strokes are the world’s leading causes of death.
Decades ago, researchers observed that fish-eating communities had very low rates of these diseases. This was later linked to omega-3 consumption.
Since then, omega-3 fatty acids have been tied to numerous benefits for heart health.
These benefits include:
Triglycerides: Omega-3s can significantly reduce levels of triglycerides.
HDL cholesterol: Some older studies suggest that omega-3s could raise HDL (good) cholesterol levels.
Blood clots: Some older research suggests that omega-3s can prevent blood platelets from clumping together, which can help prevent the formation of harmful blood clots.
Inflammation: Omega-3s reduce the production of some substances released during your body’s inflammatory response.
For some people, omega-3s can also lower LDL (bad) cholesterol. However, evidence is mixed, as some studies find increases in LDL cholesterol levels.
Despite these beneficial effects on heart disease risk factors, there is no convincing evidence that omega-3 supplements can prevent heart attacks or strokes, and many studies find no benefit.
May reduce symptoms of ADHD in children
Attention deficit hyperactivity disorder (ADHD) is a behavioral disorder characterized by inattention, hyperactivity, and impulsivity. Some research has found that children with ADHD have lower blood levels of omega-3 fatty acids than those without ADHD.
What’s more, numerous older studies suggest that omega-3 supplements could help reduce the symptoms of ADHD. In particular, omega-3s may help improve inattention and task completion. They might also decrease hyperactivity, impulsiveness, restlessness, and aggression.
However, more research is needed, as other studies have found no benefit of omega-3 supplementation on ADHD symptoms.
Could reduce symptoms of metabolic syndrome
Metabolic syndrome is a collection of conditions, such as central obesity — also known as belly fat — as well as high blood pressure, high triglycerides, high blood sugar, and low HDL (good) cholesterol levels. It is a major public health concern because it increases your risk of many other illnesses, including heart disease and diabetes.
Some research suggests that omega-3 fatty acids could help improve blood sugar levels, inflammation, and heart disease risk factors in people with metabolic syndrome.
May reduce inflammation
Inflammation is a natural response to infections and damage in your body. Therefore, it is vital for your health.
However, inflammation sometimes persists for a long time, even without an infection or injury. This is called chronic — or long-term — inflammation. Long-term inflammation may contribute to almost every chronic illness, including heart disease and cancer.
Notably, omega-3 fatty acids can reduce the production of molecules and substances linked to inflammation, such as inflammatory eicosanoids and cytokines. Studies have consistently observed a connection between omega-3 supplementation and reduced inflammation.
Might benefit autoimmune diseases
In autoimmune diseases, your immune system mistakes healthy cells for foreign cells and starts attacking them. Type 1 diabetes is one prime example, in which your immune system attacks the insulin-producing cells in your pancreas.
According to one study from 2017, increased intake of several types of fatty acids during infancy, including DHA, was linked to a lower risk of type 1 diabetes-associated autoimmunity later in life.
Omega-3s may also help treat lupus, rheumatoid arthritis, ulcerative colitis, Crohn’s disease, and psoriasis, but more research is needed.
Could improve mental disorders
Low omega-3 levels have been reported in people with psychiatric disorders. Research suggests supplementing with omega-3 fatty acids has been shown to decrease violent behavior.
Some studies also suggest that omega-3 supplements can improve symptoms in people with both schizophrenia and bipolar disorder.
However, more research is needed, as other studies have found conflicting results.
May help prevent age-related mental decline and Alzheimer’s disease
Many people experience a decline in brain function as they get older.
Several studies link higher omega-3 intake to decreased age-related mental decline and a reduced risk of Alzheimer’s disease. One review of controlled studies suggests that omega-3 supplements may be beneficial at the onset of disease when the symptoms of AD are very mild. However, More research is needed on omega-3s and brain health.
May help prevent cancer
Cancer is one of the leading causes of death in the United States, and omega-3 fatty acids have long been claimed to reduce the risk of certain cancers.
Some older studies suggest omega-3 consumption may be associated with a reduced risk of prostate cancer, breast cancer, and colon cancer. However, not all studies have reported the same results, and the NIH reports a large clinical trial found that omega 3s do not reduce your risk of cancer.
Could reduce asthma in children
Asthma is a chronic lung disease with symptoms like coughing, shortness of breath, and wheezing. Severe asthma attacks can be very dangerous. They are caused by inflammation and swelling in the airways of your lungs.
Asthma rates in the United States and around the world have been rising over the past few decades. A 2018 study found an association between omega-3 consumption and a lower risk of asthma in children.
May reduce fat in your liver
Metabolic-associated steatotic liver disease (MASLD) (formerly called non-alcoholic fatty liver disease) is a common condition characterized by the accumulation of fat in the liver. It is believed to affect 25% of the global population and is considered the leading cause of several other liver conditions, including cirrhosis, or liver scarring.
However, research suggests that supplementing with omega-3 fatty acids may help reduce liver fat and inflammation in people with NAFLD.
May improve bone and joint health
Osteoporosis and arthritis are two common disorders that affect your skeletal system. Research suggests omega-3s may help improve bone strength by boosting the amount of calcium in your bones.
Theoretically, this could lead to a reduced risk of osteoporosis. However, more research is needed, as studies have had mixed results on the effects of omega-3 fatty acids on bone health.
Omega-3s may also help treat arthritis. According to one review of six studies, omega-3 supplements were able to significantly reduce pain in people with osteoarthritis of the synovial joints. However, more large, high quality studies should be conducted to understand how omega-3 fatty acids may impact bone and joint health.
Might help alleviate menstrual pain
Menstrual pain occurs in your lower abdomen and pelvis and often radiates to your lower back and thighs. It can significantly affect your quality of life. However, studies suggest that people who consume the most omega-3s may have milder menstrual pain.
A 2023 meta-analysis of twelve studies determined that an omega-3 supplement reduced pain and the need for pain relievers during menstruation.
May improve sleep
Good sleep is one of the foundations of optimal health. Sleep deprivation has been linked to many diseases, including obesity, diabetes, and depression.
In some older studies, low levels of omega-3 fatty acids were also associated with sleep problems in children and obstructive sleep apnea in adults. Additionally, low levels of DHA are linked to lower levels of the hormone melatonin in some animal studies, which helps you fall asleep. However, further research in humans is needed.
Studies in both children and adults also suggest that supplementing with omega-3 may improve certain aspects of sleep and protect against sleep disturbances.
Could support skin health
DHA is a structural component of your skin. It is responsible for the health of cell membranes, which make up a large part of your skin.
EPA also benefits your skin in several ways, including:
promoting skin hydration
preventing hyperkeratinization of hair follicles, which appears as the little red bumps often seen on upper arms
protecting against premature aging of your skin
reducing the risk of acne
Animal studies suggest that omega-3s may also help protect your skin against sun damage. However, this doesn’t mean that you should use omega-3 supplements in place of sunscreen.
Takeaway
Omega-3 fatty acids are vital for optimal health. The best way to ensure robust omega-3 intake is to get them from whole foods, such as fatty fish, 2 times per week.
However, if you don’t eat a lot of fatty fish, then you may want to consider taking an omega-3 supplement two to three times a week. For people deficient in omega-3, this is an affordable and effective way to improve health.
