Good, still testing, but good so far

For athletes like me looking for enhanced endurance, MASI Resveratrol has shown potential. Pros include better stamina and reduced fatigue during training. However, the product could benefit from more specific guidelines on usage and timing around workouts to maximize its benefits for athletes.

What is Resveratrol?

Healthy aging is correlated with Resveratrol's influence on cellular and molecular pathways.

Resveratrol, also known as 3,5,4'-trihydroxy-trans-stilbene, is a plant-derived polyphenol that helps protect
against environmental stressors
like extreme weather and insect attacks. Found mainly in red grape skins, it also occurs in peanuts, blueberries, raspberries, mulberries, and Japanese knotweed (Hu Zhang). It's known for stimulating sirtuins, genes linked to longevity and DNA protection, and works synergistically with NAD+ enhancers like NMN.

Harvard's David Sinclair has extensively researched Resveratrol, focusing on its potential to counteract aging effects. It works by managing oxidative stress, altering energy metabolism, and regulating nutrient sensing and epigenetics, primarily through activating sirtuin 1, which may increase lifespan.
