Resveratrol

What it is

Resveratrol is a natural plant antioxidant found in red grape skins, berries, and Japanese knotweed. Plants produce resveratrol to protect themselves against weather and environmental stress. In supplements, pure trans-resveratrol helps activate cellular anti-ageing pathways and supports energy production inside your cells.

Also known as: Trans-Resveratrol, Polygonum cuspidatum extract

Key benefits

• Activates natural anti-ageing enzymes inside cells, supporting cellular longevity and energy.
• Protects blood vessels from everyday wear and tear on your cells, promoting healthy circulation and blood flow.
• Supports balanced blood sugar metabolism and healthy how well your body responds to insulin already in normal ranges.

Amplified by probiotics

When you take resveratrol, your body normally breaks it down quickly. Friendly gut bacteria help reactivate resveratrol in your intestines, keeping it active in your body for longer. At the same time, probiotic organic acids work together with resveratrol to calm gut inflammation and protect your digestive lining cells.

Typical dose

100–500 mg/day

The evidence

Human studies show that taking trans-resveratrol supports blood vessel elasticity, healthy circulation, and balanced sugar metabolism in adults. Clinical studies confirm that resveratrol activates key cellular energy and longevity enzymes. (Bhatt 2012, Evid Based Complement Alternat Med; Poulsen 2013, Diabetes).
