Bill Sardi say we may ony need around 180mgs per day

What dosage?
The human equivalent dose for a 160-pound adult would be about 1575 milligrams of resveratrol to produce the health benefits noted in the mouse study. The reporters didn’t read the study carefully, published in Nature Magazine, which said a lower-dose (~364 milligrams for a 160-pound adult) produced similar benefits.
Furthermore, the mice were engorged with fat, 60% of their daily calorie intake. Americans once consumed about 45% of daily calories from fat (1965), but that number has dropped to about 34% (2002). So a lower amount of resveratrol, maybe half as much (~180 mg) would likely be effective.
To add to the confusion, Big Pharma paid off a university researcher to tell a Canadian newspaper reporter that resveratrol is not biologically available in oral doses, when the recent National Institutes on Aging/Harvard study had proven otherwise (the mice consumed oral doses and benefited).
