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.

Nine percent of products contained only rice or wheat and none of the listed herb. Many cases of herb substitution were reported, including senna (a laxative) in a product labeled as St. John's wort. Several products were contaminated with feverfew, which should not be consumed by pregnant women and may react with a variety of medications. The researchers, from the University of Guelph in Ontario, did not disclose the identities of the tested products, which were single-ingredient herbs sold as capsules, powders, or tablets. Significant challenges continue to exist for routine use of DNA analysis of herbs, but ConsumerLab.com may use this technique where appropriate in the future, alongside other analytical techniques in its Product Reviews.

Fish Oil Helps in Schizophrenia
A study found that concentrated fish oil greatly reduced symptoms in more people who had recently experienced a first episode of schizophrenia than did a placebo. The greatest effect was on depressive symptoms, which is consistent with other studies which have shown fish oil to reduce depression, particularly in people who do not regularly eat fish.
This impact on depression has also been suggested as one reason why fish oil has shown some benefit in people with cognitive decline.

Large Study Suggests Best Vitamin D Level
What's the best level of vitamin D in your body for overall health? One way to answer this question is to compare mortality rates (deaths per year) associated different levels of vitamin D. A new study did just this, reviewing information about thousands of Americans. It concluded the best levels are between 20 and 40 ng/mL, as the risk of dying is fairly similar across this range.
