Since the Harvard resveratrol study on aging by Dr. Sinclair was published in the journal Nature a flood of dubious companies have sprung up selling resveratrol. Many have no scientist, no labs, no quality control and no experience. Dr. Oz recommends Biotivia Bioforte and Transmax. Consumer Lab, an independent testing authority, evaluated the major brands and found many lacking in content and quality. The highest potency products that passed their evaluation were Biotivia, Transmax and Bioforte. A product by Life Extension Co. failed badly with only 26% of the claimed resveratrol. Another brand, Revatrol, had virtually no trans-resveratrol in its supplement. Revgenitics refused to provide samples for testing. The ConsumerLab test results are available on their web site.

Resveratrol can help you to lead a long and healthy life so says Dr. Oz.
Red wine alone does not supply enough resveratrol to achieve the
full range of benefits because one glass of red wine has only about
1mg of resveratrol and you need about 250mg/day. You need to take
high potency resveratrol supplements to achieve the results documented
in scientific studies.Resveratrol Supplements can also help you control
your weight naturally by increasing energy, reducing cravings, and limiting
your appetite.According to Wikipedia, Consumer Lab, an independent dietary
supplement and over the counter products evaluation organization,
published a report on 13 November 2007 on the popular resveratrol
supplements. The organization reported that there exists a wide range
in quality, dose, and price among the 13 resveratrol products
evaluated. The actual amount of resveratrol contained in the
different brands range from 2.2mg for Revatrol, which claimed to have
400mg of 'Red Wine Grape Complex', to 500mg for Biotivia.com Transmax,
which is consistent with the amount claimed on the product's label.
Prices per 100mg of resveratrol ranged from less than $.30 for
products made by Biotivia.com, jarrow, and country life, to a high of
$45.27 for the Revatrol brand.
