Stroll past the supplements in any drugstore and you'll find broad claims about fish oil helping everything from heart and brain health, to joints, eyes and immune systems. But you just might be wasting your money, according to a new study.
“We know from recent large, randomized trials that fish oil supplements do not prevent heart disease in the general population, but yet they are one...
It may not get the publicity of some better-known vitamins like D, but vitamin K -- found in leafy green vegetables -- may boost lung health.
A new, large study -- published Aug. 10 in ERJ Open Research -- suggests that people who have low levels of this vitamin also have less healthy lungs. They are more likely to report having asthma, chronic obstructive pulmonary disease (COPD...
People who have psoriasis may want to get their vitamin D levels checked.
New research suggests that blood levels of the so-called "sunshine vitamin" may affect the severity of their condition. In psoriasis, skin cells build up and form dry, itchy, sometimes painful patches.
While synthetic vitamin D creams are an emerging therapy, the study suggests that a diet rich in vitamin D or...
Vitamin D supplements might lower the risk of heart attack and other cardiac ills for people over 60 -- especially if they're already taking heart meds, a new study suggests.
"Our results suggest that further exploration of the possible benefit of vitamin D on cardiovascular events, particularly in those at higher risk of having an event, might be warranted," said senior researcher
Quite possibly, a team of British and Canadian researchers report.
In their study, investigators spent roughly a decade tracking more than 12,000 older people. None had dementia at the start of the study period. In the end, the team determined that those who had been taking vitamin D supplements during that time appeared to face a 40% lower ri...
Vitamin D supplements are typically used to guard against bone loss and fractures, but new research offers up another possibility: For folks with pre-diabetes, they may help lower the chances of a full diabetes diagnosis.
Across three clinical trials, investigators found that vitamin D supplements were modestly effective in curbing the risk of pre-diabetes progressing to type 2 diabetes. ...
Androstenedione is one of those supplements that was peddled to athletes for years as a quick path to bulging muscles and high testosterone levels, but it carries some grave dangers.
Also known as "andro," the dietary supplement was once touted to enhance athletic performance by stimulating muscle growth and boosting testosterone levels. But once it enters the body, it acts like a st...
A new study hints that treating low vitamin D levels with supplements might have a critical benefit for certain people: a decreased risk of attempting suicide.
In a study of more than 1 million U.S. veterans, researchers found that those prescribed vitamin D were nearly 50% less likely to attempt suicide over eight years, versus those who were not prescribed the supplements.
Babies born prematurely who are fed formula may need iron supplementation like their breastfed counterparts, new research suggests.
“Just because a baby is on iron-rich formula, we should not assume all of their iron needs are being met, since iron from the formula may not have the same absorption as iron from breast milk,” said researcher Grace Power. She is a third-year medical stu...
Older adults who harbor more vitamin D in their brains may stay mentally sharper, a new study suggests.
Researchers found that when older adults had higher levels of vitamin D in their brain tissue, they tended to perform better on standard tests of memory and thinking. They were also less likely to have dementia or milder cognitive impairments.
Manufacturers make all kinds of health claims, but can taking a dietary supplement actually lower your heart disease risk?
A comprehensive analysis of prior research suggests that in certain cases the answer is yes. Some types of supplements -- such as omega-3 fatty acids, folic acid and coenzyme Q10 (CoQ10) -- do provide a cardiovascular leg up.
Eating more berries and drinking tea may help slow mental decline as you age, new research suggests.
In a study of more than 900 adults, researchers found that foods like these -- containing antioxidant flavonols -- delivered brain benefits to older adults. Flavonols are found in fruits like berries, green leafy vegetables, tea and wine.
Kids can take part in sports while on vegetarian and vegan diets, but parents and caregivers must help them select foods that will fuel them and meet their nutrition needs.
Vegan athletes can become deficient in vitamin B12, vitamin D, long-chain omega-3 fats, riboflavin and calcium, so it's important to find good substitutes, said Roberta Anding, a registered dietitian at Baylor College ...
Vitamin D supplements are often touted for their health benefits, from boosting the immune system to guarding against cancer. But as one British man found out, it is possible to get too much of a good thing.
Vitamin D overdosing -- clinically called hypervitaminosis D -- is linked to a range of potentia...
Vitamin D, the "Sunshine Vitamin," boosts the immune system and helps prevent cancer, among other health benefits, but a significant number of Black and Hispanic teens have low levels of this nutrient, according to a new study.
"This paper calls attention to the need to raise...
If your child is a picky eater and you feel you need to give them dietary supplements, you're not alone.
In a new poll of more than 1,200 U.S. parents with at least one child aged 1 to 10, more than half said they struggle to get their child to eat a well-balanced diet and half said they regularly give their child dietary supplements.
About one-third of parents said their child is a...
Taking vitamin D supplements may help stave off psoriasis, rheumatoid arthritis, lupus and other autoimmune diseases, a new study suggests.
Previous research has hinted at this connection, but the new study is the first randomized controlled trial to look at what happens when people are given vitamin D supplements and followed to see if they develop an
Children at risk for multiple sclerosis (MS) might find some protection from the disease by spending more time in the sun, a small study suggests.
Although MS is rare in children and young adults, those with relatives who have the condition have increased odds of developing the disease early. Exposure to sunlight may cut their risk in half, researchers say.
Most people know that sun-sourced vitamin D is good for their bones. So could avoiding the sun to reduce skin cancer risk weaken your bones?
A new study brings a reassuring answer: "Sun-protective" behavior -- wearing long sleeves, seeking shade or using sunscreen -- "was not associated with decreased bone mineral density or increased risk of osteoporotic fracture," the researchers conclu...
