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

Over the years, ConsumerLab.com 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) >>

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.

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.
