Resveratrol: You don’t always get what you pay for
Resveratrol supplements have been popular since 2006, when studies in animals showed “life-extending” and “endurance-enhancing” effects. Similar evidence doesn’t exist for people, which is the reason there are few posts about it on this site.
ConsumerLab.com’s most recent tests revealed that 2 resveratrol supplements provided only 43% and 87%, respectively, of their listed amounts of resveratrol.
These products were among the most expensive supplements of the 10 products selected for review.
None of the resveratrol products were contaminated with lead or cadmium, which can occur in plant-based supplements, and all tablets were able to properly break apart in solution.
The bottom line?
That’s correct, 20% of the products were mislabeled.
Based on a daily dose of 400 mg of resveratrol, the cost would range from $0.60 to $11.04 per day!
