How To Get Vitamin K From Food
Many of the benefits of vitamin K - such as proper blood clotting and calcium utilization for bone and heart health - are associated with getting adequate vitamin K from foods. The good news?

Niacin Concern Stops Cardiovascular Study
A clinical trial using high dose niacin (vitamin B3) was recently stopped by the National Institutes of Health due to lack of benefit and a small increase in strokes.

Omega-3s Linked to Less Heart Disease and Longer Life
A study among older individuals who did not use fish oil supplements showed that those with higher levels of omega-3 fatty acids in their blood were far less likely to have a heart attack or arrhythmia and were 27% less likely to die during the 14-year study.

Some Concern About Theobromine in Dark Chocolate
ConsumerLab's tests of dark chocolates show them to contain about as much theobromine (a caffeine-related stimulant) as heart-healthy flavanols. So is all this theobromine good or bad? A recent study suggests that it may be an issue for people who need to control their blood sugar, while, on the positive side, it lowers LDL "bad" cholesterol. Get the details in the "Concerns and Cautions" section of the Cocoa Powders, Dark Chocolate, Extracts, Nibs, & Supplements Review, which includes comparisons of the amounts of theobromine in popular products, as well as amounts of flavanols, caffeine, and contaminants.
