(Trans-)Resveratrol is one of several compounds researched by Harvard Professor David Sinclair, who has been researching the biological basis of aging for decades. Study results suggest that the aging process can be slowed by administration of resveratrol. Resveratrol, like a low-calorie diet, promotes the expression of sirtuin genes such as Sir2. As a result, a life-prolonging effect was observed in various experimental animals. In an animal study, mice were given a high-fat diet. The concomitant use of resveratrol significantly reduced the weight gain. At particularly high resveratrol doses, a doubling of endurance performance was observed. - Dr. Sinclair claims to be in an interview on YouTube, parallel to NMN (see our separate offers), 1 gram of resveratrol per day and considers this dose to be completely harmless.
