Isn't your health worth it?
Resveratrol supplements have been popular since 2006, when studies in animals showed "life-extending" and "endurance-enhancing" effects, among other potential benefits.  Although similar evidence does not yet exist for people, a wide-range of resveratrol (or "red wine extract") supplements are marketed, including capsules, liquids, and tablets. tested many popular resveratrol supplements on the market. One supplement was discovered to contain only 2 mg of resveratrol per capsule -- that's just 1 to 2% of the amount provided by most other products. Another supplement failed to break apart properly in disintegration testing. A third resveratrol product lacked FDA-required ingredient labeling.  The good news is that many other resveratrol supplements contained their claimed amounts of resveratrol (30 mg to 250 mg per serving) and passed other important tests -- including tests for contamination by lead and cadmium, which are toxic heavy metals.
Among the quality-approved products, calculated the cost to obtain 100 mg of resveratrol to be as much as $3, or as little as just 6 cents -- a huge potential savings!
