Don't Be Fooled by "Good Source of Omega-3s" Claim

Over the years, has pointed out that products sometimes claim to provide a percentage of the Daily Value (DV) of omega-3 or -6 fatty acids, even though no such Daily Value has been established. Now, the FDA has prohibited certain related statements on omega-3 supplement and food labels that could mislead consumers into thinking a product provides some percentage of this imaginary amount. Get the details, including what to watch out for on labels, plus our tests of fish oil and other omega-3 fatty acid supplements, in the updated Fish Oil and Omega-3 Fatty Acid Supplements Review (Including Krill, Algae, Calamari, Green-lipped Mussel Oil) >>

Calcium and Colon Polyp Risk

A large study evaluated the effects of taking calcium and/or vitamin D on the risk of developing precancerous colorectal polyps in people with previous polyps. While there was no effect during the study, a follow up study is now showing much higher rates of polyps among those who had taken certain supplements. Get the details in the What It Does section of the Calcium Supplements Review.

Too Much Vitamin D Weakens Legs

In recent months we have reported that giving too much vitamin D to people who don't need it increases the risk of falls.

Fish Oil Benefit Questioned

There are many potential benefits from supplementing with the omega-3 fatty acids found in fish oil, but the most widely-touted benefits -- reducing the risks of heart disease and stroke -- are now in doubt.

Algal Oil vs. Fish Oil

Fish get their omega-3's from algae and many people are now doing the same by taking algal oil, but how does it compare to fish oil? Experts recently reviewed studies of algal oil and concluded that it boosts ("good") cholesterol but it also increases LDL cholesterol -- which is often thought of as "bad" cholesterol. But there's more to the story. Get the details in the recently updated Fish/Marine Oil Supplements Review, which includes our test results for algal, krill, and fish oil supplements.

L-Tryptophan -- Still a Problem?

A woman in Illinois taking L-tryptophan for insomnia developed the same serious problems that resulted in L-tryptophan being temporarily removed from the market several years ago. Is L-tryptophan any safer now than it was before? For more information, see the update to the L-Tryptophan and 5-HTP Review Article.

Pea Protein for Muscle

Like whey protein, pea protein is now being used in protein powders. A recent placebo-controlled study compared the two and suggests that pea protein is a viable option for increasing muscle mass. See the details in the Protein Supplements Review >> 

Omega-3's May Be Important in Preventing Cognitive Decline

We have reported in the past that a certain combination of B vitamins slowed cognitive decline as well as brain shrinkage in older people.

Get the details in the B Vitamins Supplements Review >>

Zinc Concern

J&J Vaccine Boosters

A booster vaccine is now recommended for everyone who received a J&J vaccine at least two months ago and the booster will likely be available soon. However, be aware that a booster of the Moderna or Pfizer vaccine may boost immunity more than a J&J booster, according to a recent study.

Booster Availability

Boosters are now authorized for specific people who received the Moderna or J&J vaccines, in addition to the Pfizer vaccine. See the details.

Does Your Multivitamin Have Too Much Folic Acid?

Folic acid is in multivitamins because it is provides the essential B vitamin, folate. Getting too much folate, however, carries risks. What most people don't know is that you actually get 70% more folate from folic acid than labels currently reveal and many supplements expose you to amounts of folate which are not only way above what you need but over the daily limit for tolerable intake. Companies now have until mid-2018 or later correct their labels, but until then you may be in the dark.

To find out which multivitamins exceed the tolerable limit for folate, see the update in the Multivitamins Review. You'll also learn how the daily requirements for many other nutrients have changed and differ from what labels currently tell you.
