Taking in extra vitamin D plus calcium might cut your odds of getting a debilitating form of vertigo, new research shows.

Can zinc help shorten a COVID-19 infection? Will vitamin C or other supplements prevent it?

These claims and plenty more can be found on social media and internet sites, but be advised: There is no pill or treatment that can prevent or cure COVID right now.

"We want to think that there is a quick way to get rid of this. But there is not a product out there that will keep y...

A green tea extract has shown early hints of promise against a serious, progressive form of lung disease, researchers say.

The disease is called pulmonary fibrosis, where scar tissue builds up in the lungs over time, limiting the amount of oxygen the body receives. Eventually, life-threatening lung failure can develop.

There are many types of pulmonary fibrosis, but the most...

Every day, millions of Americans pop a fish oil supplement -- rich in healthy omega-3 fatty acids -- in hopes it'll improve their health.

A big new data review suggests they may be half right: The supplements may slightly reduce a person's risk of heart disease, but they won't ward off cancers.

In fact, men who took the supplements actually had a slight uptick in their ris...

Couples struggling to get pregnant might want to add a little more fish in their diet, a new study says.

Young men who take fish oil supplements appear to have better sperm quality and higher testosterone levels than those who don't, as well as larger testicles, researchers report.

Although it wasn't tested as part of the study, all these male reproductive factors should lea...

Many people turn to the internet with health questions, but how reliable is the information you find? When it comes to probiotics, a new study urges caution.

The research found that of 150 websites that came up with a search of probiotics, most were commercial sites, hoping to sell a product. Others were news sites or health portals (providing links to other sites). Many of these site...

Supplements containing zinc and folic acid don't appear to boost male fertility, a new study finds.

Despite marketing claims, these supplements don't improve pregnancy rates, sperm counts or sperm function, researchers say.

"Our results suggest that these dietary supplements have little to no effect on fertility and may even cause mild gastrointestinal symptoms," researche...

Taking calcium and vitamin D might help older adults curb the risk of a bone fracture, but vitamin D alone does not do the job, a new research review concludes.

The analysis of 28 past studies found that older adults with higher blood levels of vitamin D were less likely to suffer a broken hip or other fracture over five to 15 years.

But the picture was different in studies ...

The U.S. Food and Drug Administration on Friday gave expanded approval to a prescription form of fish oil called Vascepa, to help prevent heart trouble in people at high risk who are already taking statins.

Vascepa (icosapent ethyl) was already FDA-approved for a small percentage of patients with exceptionally high blood levels of triglycerides, a type of blood fat.

The new ...

Children with attention-deficit/hyperactivity disorder (ADHD) and low blood levels of omega-3 fatty acids might benefit from supplements, new research suggests.

Fish oil supplements appeared to boost attention in these kids, British researchers report.

The effect seemed limited to youngsters who weren't already getting enough omega-3 in their diets, however.

Prior ...

Prescription-strength fish oil slows the development of artery-clogging plaques, according to early results from an ongoing clinical trial.

Icosapent ethyl, sold under the brand name Vascepa, is a drug derived from fish that contains pure EPA, a key nutrient in fish oil. In the new study, Vascepa appeared to put the brakes on key aspects of plaque formation in vessels after nine month...

Many Americans believe they are likely to develop dementia -- and they often turn to unproven ways to try to better their odds, a new study suggests.

In a survey, researchers found that almost half of Americans in their 50s and 60s believed they were at least "somewhat likely" to develop dementia. Yet few -- 5% -- said they had talked to their doctor about ways to lower their risk...

Fish oil might help people with heart failure avoid repeat trips to the hospital, a new study suggests.

The findings come from an analysis of a clinical trial first published last year, where researchers tested the effects of fish oil and vitamin D on people's risk of heart disease and cancer.

That main trial -- called the Vitamin D and Omega-3 Trial (VITAL) -- had some enco...

Taking vitamin D and fish oil supplements won't prevent kidney disease in people with type 2 diabetes, a new study finds.

"We wanted this study to clarify whether these supplements have any real kidney benefit in adults with diabetes. Even if it's ...

The popular herbal supplement kratom may cause liver damage, researchers warn.

Kratom is widely available in smoke shops and online. It's a botanical product made from Mitragyna speciosa, a tropical evergreen tree found in Southeast Asia. At low doses, it's a stimulant. At high doses, it has an opioid-like effect.

Use of kratom has risen sharply since the start of...

Biotin supplements, often taken to improve hair, skin and nails, can interfere with the results of some critical lab tests, the U.S. Food and Drug Administration warned Tuesday.

The FDA is particularly concerned about biotin interference causing a falsely low result for troponin, which is key in diagnosing heart attack. The agency said in a statement that it continues to receive repor...

Millions of Americans pop a fish oil supplement each day, hoping to bolster their heart health. Now, research suggests they may be on the right track.

The most up-to-date review of data from 13 prior studies found daily omega-3 fish oil supplement use tied to a significant lowering of risk for heart attack, according to a team led by Dr. JoAnn Manson. She is a professor of epidemiolog...

If you're a young adult, start thinking about your bone health, an expert advises.

Most people reach peak bone mass -- the strongest bones they'll ever have -- between 25 and 30 years of age, according to Dr. Philip Bosha, a physician with Penn State Sports Medicine in State College, Pa.

"To some extent, genetics determines the peak, but lifestyle influences, such as diet an...

WEDNESDAY, Aug. 21, 2019 (HealthDay News) -- It would be welcome news to millions if fish oil supplements were proven to help prevent diabetes. But new research delivers very disappointing data on the prospect.

Previous research has hinted that fish oil supplements -- which contain omega-3 fatty acids -- might improve blood sugar metabolism and possibly stave off type 2 diabetes. Bu...

Large pills and dietary supplements can be tough for anyone to swallow, but new research finds they may pose a potentially dire risk to seniors.

A study from the U.S. Food and Drug Administration found that between 2006 and 2015, almost 4,000 people had trouble swallowing dietary supplements that was serious enough to report. Three people died after choking on them.

Wondering if you can do more than slap on some sunscreen to prevent skin cancer? A new study suggests that getting more vitamin A may help.

The study of around 125,000 Americans found that people with the highest intake of vitamin A lowered their risk of squamous cell skin cancer by around 15%. Most of the vitamin A they consumed came from foods.

"These findings just ...

After vitamins and minerals, fish oil with its omega-3 fatty acids is the most widely used supplement, taken by an estimated 10% of Americans.

So, when research reviews show that it doesn't provide the health benefits for people with heart conditions that researchers thought it did, it's hard to know what to do.

One thing researchers do know is that omega-3s are essenti...

If you take supplements hoping to ward off a heart attack or stroke, yet another study suggests you could find better uses for your hard-earned dollars.

A review of 277 published studies found that most supplements won't protect you from cardiovascular disease or early death.

"The study carries a simple message -- do not waste your money," said lead researcher Dr. Safi Khan....

It's well known that omega-3 fatty acids, or omega-3s for short, are important anti-inflammatory nutrients that, along with many other functions, reduce heart disease risk. What's unclear is whether you can get these benefits from a capsule. Studies involving supplements have recently been called into question.

That's why it makes sense to focus on foods rich in these fatty acids. Not...

Supplements of a type of gut bacteria may benefit people at heightened risk of diabetes and heart disease, a preliminary study suggests.

Researchers found that the supplements, containing bacteria called Akkermansia muciniphila, appear safe and potentially effective.

Over three months, volunteers who used a pasteurized version of the supplement lost an average of 5 po...

Image is everything for most teens and young adults, and 22% of young men and 5% of young women turn to potentially dangerous methods to "bulk up," a new study says.

"Parents and teens should be...

If you're looking to improve your heart health, getting regular exercise and eating healthy foods can definitely help, but new research says popping a daily vitamin D supplement won't.

Vitamin supplements don't appear to prevent type 2 diabetes in those at highest risk for the disease, a new study finds.

Some studies have suggested that low vitamin D levels might increase the odds of developing diabetes and that boosting levels could prevent it, but these findings throw cold water on these assumptions.

In this study funded by the U.S. National Institutes...

Americans are making shifts in the supplements they take -- fewer multivitamins and vitamins C and E, more fish oil and vitamin D. Many think of supplements as magic bullets, but studies don't always support their supposed benefits.

Some research is positive. Vitamin D is important for good health and very hard to get naturally from foods or, if you live in northern latitudes, from th...

While taking vitamins may be fine for teens and young adults, supplements for weight loss, muscle-building and added energy may trigger severe medical problems, new research suggests.

"We're advising pregnant women and women who could become pregnant not to take vinpocetine," FDA Deputy Commissioner Dr...

It seems an unlikely way to ease anxiety, but new research suggests that regulating the bacteria in your gut might help.

As many as one-third of people suffer anxiety symptoms during their lives, including irrational fears, agitation, fatigue or panic attacks. Anxiety is common in pe...

TUESDAY, May 14, 2019 (HealthDay News) -- Glucosamine has long been used as a supplement to help ease the joint pain of arthritis, but new research suggests its anti-inflammatory properties might also lower heart disease risk.

SATURDAY, May 4, 2019 (HealthDay News) -- Buyer beware: When it comes to testosterone supplements, men should know a new study finds there is precious little evidence to support claims they will boost testosterone levels, sex drive, strength and overall energy.

To come to this conclusion, the researchers first broke down 50 testosterone supplements into th...

One out of every three U.S. cancer patients uses alternative or complementary therapies, but many keep that info from their doctors, a new study finds.

"You don't know what's in them," said Dr. Nina Sanford, assistant professor of radiation oncology at U...

If you're popping dietary supplements in the hope of living longer, a large new study suggests you'd be better off investing that money in nutritious foods.

"Although vitamin D toxicity is rare owing to a large the...

She thought red yeast supplements would be a natural way to lower her cholesterol. What could be easier?

Instead, the 64-year-old woman landed in the hospital with acute liver damage that her doctors say was likely caused by taking the over-the-counter product.

"Many people are cautious to use [prescription] medications because of potential side effects, and rightly so," but...

To take calcium or not to take calcium, that is still the question.

Excess weight is often linked with depression, the ...

Obese young children may have less risk for high blood pressure if their mother took the omega-3 fatty acid DHA -- found in fish oil -- during pregnancy, new research suggests.

The findings could be important since rising numbers of American children are obese and experiencing hikes in blood pressure.

That could have long-term consequences for their health, said study co-aut...

A typical workout doesn't give you license to eat whatever you want.

Even a full hour of vigorous skiing burns just 600 calories -- less than the amount in a super-sized fast food sandwich. That's why it's important to think of exercise as just one part of a shape-up plan.

Exercise works the cardiovascular system and builds muscle, but it takes calorie restriction to also lo...

The U.S. Food and Drug Administration plans to strengthen regulation of dietary supplements, such as vitamins, minerals and herbs, the agency announced Monday.

The Vit...

The U.S. Drug and Food Administration has repeatedly warned manufacturers that many dietary supplements contain dangerous, experimental stimulants. But according to a new report, 75 percent of supplements tested still contain the compounds.

From 2007 ...

Vitamin D supplements have long been touted as a way to improve bone health and possibly ward off the bone-thinning disease osteoporosis in older adults.
