Resveratrol
Basic information:
Plant original: Polygonum cuspidatum Sieb. et Zucc.
Specifications: 20%-98% Trans-resveratrol Test by HPLC
Molecular Formula: C14H12O3
Molecular Mass: 228.24
CAS No: 501-36-0
Indications and Uses
Studies suggest that resveratrol has anti-atherosclerotic activity and that it might have some immune-stimulating and anti-cancer effects. Human studies are few in number and inconclusive due to short duration and poor design.
Safety Concerns
Pregnant women and nursing mothers should avoid the use of resveratrol-containing supplements. They should also avoid the use of wine as a resveratrol source. Purple grape juice is a good and safe source of resveratrol, as well as other polyphenolic antioxidants.
Dosage Information
Resveratrol, marketed as a nutritional supplement, is typically an extract of Polygonum cuspidatum (see Description). Such an extract contains both cis- and trans-resveratrol. The extracts are usually standardized to deliver about 8% resveratrol in its various forms. Many of the products currently marketed have resveratrol in combination with other phytonutrients and vitamins. Some supplements deliver 16 milligrams per serving or higher. There is no typical dosage. Functional food products containing resveratrol are being developed.
