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. However, a closer look at the findings suggests an even smaller range actually associated with the lowest mortality. For the details, as well as our suggestions on how to use vitamin D, and quality ratings of products, see the Vitamin D Review. More >>

Spoiled Fish Oil Is Less Effective
Spoiled fish oil does not lower LDL "bad" cholesterol, while the same amount of non-spoiled fish oil does, according to a new study.

(It may also be best to choose an oil in the triglyceride form, rather than the ethyl ester form). For details, see the "Quality Concerns" section of the Fish Oil Supplements Review. Also see our Top Picks among fish oils.
