Inaccurate Yohimbe Labels -- (9/30/2015) Yohimbe supplements contain an active compound, yohimbine, which is an old drug for erectile dysfunction. A recent study found that most yohimbe supplements don't list the amount of yohimbine they contain, and those that do are typically inaccurate — similar to what has found. For more about the study as well as our own tests of products, see the Sexual Enhancement Supplements Review >>

Resveratrol for Alzheimer's Disease? -- (9/12/2015) High doses of a synthetic resveratrol stabilized a marker of disease progression in people with mild to moderate Alzheimer's, a recent study reports.

Get the details about this and other studies with resveratrol, and our tests and comparisons of products, in the Resveratrol Supplements Review >>
Vitamin C: The Exercise Replacement? -- (9/9/2015) A small clinical study recently found that taking vitamin C had a positive effect on blood vessels similar to a daily walk.

Get details about the study (including dose) and other pros and cons of vitamin C in the Vitamin C Supplements Review >>

Vitamin D Increases Strength -- (9/2/2015) A recently published review of clinical studies found that supplementing with vitamin D can improve muscle strength in young, healthy men and women.

Get the details in the "Muscle, balance and falls" section of the Vitamin D Supplements Review >>
