Resveratrol: Thousands of Bottles of Wine, High-Dose Pills Not Required; Mega-doses May Induce Side Effects
Date:6/3/2008

Dynamic Dosing Of Resveratrol Recommended For Optimal Health

SAN DIMAS, Calif., June 3 /PRNewswire/ -- While an earlier published rodent study showed that ultra-high doses of resveratrol (1565 milligram human dose), equivalent to 1500 bottles of wine or many dietary supplement capsules, successfully overcame the adverse effects of a high-fat diet, the lowest dose that genetically mimics a calorie restricted diet went undetermined, till now.

Now an authoritative gene array study, conducted by researchers at the William S. Middleton Memorial Veterans Hospital and Lifegen Technologies in Madison, Wisconsin, shows that a dose of resveratrol (rez-vair-aw-trawl) ~343 milligrams per day (4.9 mg per kilogram of body weight) produces a gene activation profile similar to a calorie restricted diet. Supra-high doses (greater than 500 milligrams) are not required and may produce side effects. [PLOS1, June 2008 available online http://www.plosone.org/home.action ]

Both calorie restriction and resveratrol have been shown to prolong the life of all life forms, ranging from single-cell organisms (yeast cells) to more complex forms of life (fruit flies, roundworms) and warm-blooded mammals (laboratory rats).

Consumers never heard that a far lower human equivalent dose than 1565 milligrams (~360 milligrams) was employed with undisclosed success in a landmark rodent study published in 2006. The lower-dose data were never published. [Resveratrol improves health and survival of mice on a high-calorie diet. Nature 2006 Nov 16; 444: 337-42]
