February
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.
Mediterranean Diet with Olive Oil Improves Depression -- A recent study found that men and women with major depression who consumed a Mediterranean diet with olive oil had significant improvement in symptoms compared to those who maintained their typical diet. Get the details in the "What It Does" section of the Olive Oil Review (which includes our tests of products) >>
Selenium and Ovarian Cancer -- A recent study found that women with the highest intakes of selenium from supplements had a much lower risk of ovarian cancer than those not getting selenium from supplements.

Vitamin D Reduces Risk of Colds & Flu -- A study released today shows that taking vitamin D in a certain way reduces the risk of cold and flu infections by up to 70%.

Probiotics and Weight? -- Several studies, including a recent one in Brazil, suggest that probiotics can help with weight reduction or other aspects of slimming.

Colon Polyps and Green Tea -- A study of middle-aged men and women found that those given green tea extract after colon polyp removal were much less likely to develop additional polyps than those who did not take the extract. For details about the extract and dose, see the "What It Does" section of the Green Tea Supplements Review (which includes our tests of supplements and teas) >>
Caution: Turmeric Drug Interaction -- It was recently reported that a man consuming large daily amounts of turmeric experienced kidney toxicity, likely due to an interaction between turmeric and the drug he was taking.

Enzymes for Muscle Soreness -- A blend of enzymes reduced delayed-onset muscle soreness after exercise in healthy men. For details, see the "What They Do" section of the Digestive Enzyme Supplements Review >>

For details, see the "What It Does" section of the Fish Oil Supplements Review >>
Melatonin Quality Concern -- A recent Canadian study found that 71% of melatonin supplements did not contain within 10% of labeled amounts of melatonin. Certain types were more likely to be off-the-mark than others. For details, and our own tests of (U.S.) products, see the "Quality Concerns" section of the Melatonin Supplements Review >>
Potential Risk with High B-12 -- Among people who are malnourished, those with elevated vitamin B-12 levels in their blood were twice as likely to die when hospitalized as those with lower B-12 levels, according to a new study. The study authors suggest caution with inappropriate supplementation. For more details about the study, and vitamin B-12, see the B Vitamin Supplements Review >>

Supplement vs. Prescription Fish Oil? -- As we have written before, by choosing an extremely concentrated fish oil supplement, you can get essentially the same type of fish oil as you would get from a prescription fish oil. But according to a recent study, fish oil supplements are more likely to be rancid (oxidized) than prescription fish oil. However, a closer look at the study by ConsumerLab staff suggests that this finding may be misleading, as explained in the "Quality Concerns" section of the Fish Oil Supplements Review >>
