Caution with Energy Drinks

The FDA has released reports showing deaths and other serious adverse events associated with the use of energy drinks like 5-hour Energy. As reported in September, these small "shot" drinks can pack more caffeine than 2 cups of regular coffee. While the caffeine can keep you alert, there are a number of concerns to bear in mind and suggestions on how to more safely use these drinks. Learn more in the update to our B Vitamins and Energy Drinks Review. More >>

Autism and Folic Acid Supplements

A new study found that women who took folic acid supplements around the time of conception had a significantly reduced risk of bearing a child with autistic disorder. Get more details in the recent update to the folic acid section of the B Vitamins Review >>

Vitamin D and Pregnancy

For details, see the update in the Vitamin D Supplements Review, which includes our tests of vitamin D supplements and extensive information about the use of vitamin D. More >>

Does Fish Oil Help During Pregnancy?

A recent study shows that, at age 4, children born to women given DHA-rich fish oil during pregnancy do not fare better cognitively than other children. Other positive effects around the time of birth, however, suggest that supplementation may be worthwhile. For details, as well as our tests of fish oil supplements, see the Fish Oil and Omega-3 Fatty Acid Supplements Review (Including Krill, Algae, Calamari, Green-lipped Mussel Oil) >>   

Vitamin D and MS

A study found that children born to women significantly deficient in vitamin D during pregnancy were much more likely to develop multiple sclerosis as adults. For details, see the "What It Does" section of the Vitamin D Supplements Review >>

Autism Risk With Low Vitamin D

Babies born with very low blood levels of vitamin D are more likely to be autistic, according to a new study. This is consistent with a study published last year showing a higher rate of autistic children in mothers with very low vitamin D blood levels during pregnancy. Get the details in the "What It Does" section of the Vitamin D Supplements Review >> (Also see our Top Picks among vitamin D supplements.)

DHA for Toddlers?

Does giving the omega-3 fatty acid DHA to 1-year-olds born pre-term lead to improvements in cognitive development? Find out in the recent update to the What It Does section of the Fish Oil & Omega-3 Supplements Review -- and learn whether DHA use by pregnant women yields benefits for their children.

Be Careful with Iodine -- Especially If You're Pregnant

Unlike over-the-counter medicines, dietary supplements are generally not required to carry warning labels, even if they contain toxic amounts of ingredients. If you don't know how much of a vitamin, mineral, or other ingredient you really need, it's easily possible to get too much. This is what seems to have happened to some pregnant women taking a widely-sold iodine supplement, according to a recent medical report. Just one tablet contained 57 times the daily iodine they needed and more than ten times the limit associated with increased risk of toxicity. Their children were born with congenital hypothyroidism, apparently due to getting too much iodine from their mothers.

Find out which product these women took in the updated Iodine section of the Multivitamin Supplements Review. You'll also find appropriate levels of other vitamins and minerals and see which products in the Review did or did not exceed tolerable intake levels of vitamins and minerals. More >>
