Resveratrol supplement with Antioxidant ORAC of 19,638 - longevity93 - 07-06-2009 10:47 PM
The dietary supplement Vindure 900 has recently posted its ORAC value of 19,638 as tested by Brunswick Labs. The formulation for a single tablet includes:
- 400 mg 98% pure Resveratrol
- 400 mg Red Wine Grape extract (90% polyphenols)
- 100 mg Quercetin
This tested value coincides with the calculated value since the exact formulation is 428 mg of Resveratrol, and 117 mg of Quercetin.

Hmm.. Indeed the bioavailability of resveratrol is quite low but it's apparently showing that is safer to take than any other antioxidant supplements when considering both the benefits and side effects.

Quote:(...) there is little evidence that resveratrol is an important antioxidant in vivo. Upon oral consumption of resveratrol, circulating and intracellular levels of resveratrol in humans are likely to be much lower than that of other important antioxidants, such as vitamin C, uric acid, vitamin E, and glutathione. Moreover, the antioxidant activity of resveratrol metabolites, which comprise most of the circulating resveratrol, may be lower than that of resveratrol.
The problem is that humans have a problem benefiting from oral doses of resveratol, since its bioavailability is very low. So this impressive ORAC score in fact does not mean that much because you can't absorb it.
