Wellness Resources Resveratrol Ultra 500 contains 500mg trans-resveratrol per capsule! It is the highest potency, ultra-pure resveratrol standardized to 98% actual trans-resveratrol, the active compound. Most other resveratrol supplements are only 50% trans resveratrol. So, a capsule that contains 500mg resveratrol is actually 250 trans-resveratrol. Oftentimes resveratrol supplements advertise "1000mg resveratrol". However, this is typically for a serving size of 2 capsules (really 500mg per capsule) and 50% trans-resveratrol (so 250mg trans-resveratrol per capsule). We think this is confusing and misleading! At Wellness Resources, we clearly list the the actual amount of trans-resveratrol in each capsule (500mg). It is an excellent value for a superior supplement! Resveratrol is a polyphenol found in red wine that promotes heart health, normal immune response, mitochondrial health, and telomere health.* Resveratrol is found in some red wines and is believed to be a key reason for the French paradox, wherein a higher level of saturated fat is consumed and heart health is maintained. Research shows that resveratrol protects against some metabolic stressors associated with a high fat diet.* Resveratrol acts through a variety of natural mechanisms to enhance health, and much research points to these mechanisms in an anti-aging context similar to the beneficial effects seen in calorie restriction (by activating a gene called SIRT1).* Resveratrol is a potent antioxidant, working synergistically as part of the antioxidant network. It has been shown to enhance the function of an important cellular antioxidant enzyme called MnSOD, which helps keep mitochondria in good working order to make energy more efficiently while protecting against damage. It also helps modulate NF-kappaB, the key stress and inflammation gene signal within a cell.*
