Resveratrol: A Review of Human Clinical Trials


Resveratrol, a naturally occurring compound found in grapes, berries, and other plants, has been the subject of numerous studies for its potential health benefits. It is known for its antioxidant, anti-inflammatory, and cardiovascular properties.

In recent years, many human clinical trials have been conducted to investigate the effects of resveratrol on human health, including a new analysis of a combined 25 previous research articles, numbering well over 1,000 participants.  According to the authors, it concluded that resveratrol had a dramatic impact in regulating both lipid and glucose metabolism.

In this article, we will review the key findings of all human trials on resveratrol.

  1. Ingrid Suhr says:

    I’m 75 and have been taking Resveratrol for about 7 or 8 years. Was taking a German make up to 500 mg/day but now am taking Renue by Science Lipo Resveratrol 125 mg/per day. I have to buy a double quantity as my husband is also taking it. I’m a little worried we’re not taking enough! Could you put me straight on this matter?
