A compound that is getting a great deal of interest right now by equally researchers and also the mass media is Resveratrol (Res), which is a phytoestrogen along with antioxidant produced from grapes. It is a compound that is found to act as an anti estrogen, Inhibits aromatase (the enzyme which converts testosterone to estrogens) at high doses, might have effects on weight reduction, and also has many possible health associated benefits.
Up to now, the material looks to some wonder compound. Lastly, recent studies also recommend it might increase testosterone levels, and that's got bodybuilders and other professional athletes, as well as dietary supplement companies, excited as one may well assume.
One recent analysis getting a fantastic deal of interest entitled "trans Resveratrol relaxes the corpus cavernosum ex vivo and also improves testosterone booster natural (www.kitsapdailynews.com) levels and sperm quality in vivo" found results on testosterone levels in rabbits. This study noted that rats given Res orally at fifty mg/ kg for 28 days concluded
"... resveratrol has a favorable influence on male reproductive function by triggering a penile erection and enhancing blood testosterone levels, testicular sperm counts, along with epididymal sperm motility." (1)
Two essential points to remember: the analysis was done in rabbits and at really high doses. to be able to find the dose utilized in the analysis as it holds true for you, that had been 50 mg/ kg, use the weight of yours in lbs divided by 2.2 X 50 = dose required according to this particular study...However, an additional study carried out in animals employed a dosage: 20 mg/(kg d) also had results on testosterone, making sure that could be best starting dose. It is not identified of course in case this is the human equivalent dose (HED) or even exactly what the HED is at this time period to impact testosterone in people or even though it will!
Unfortunately, no conclusive human studies exist only at that moment, so the "optimal" measure is a WAG at this time. But, anecdotal stories of individuals using 500mg - 1000mg report results, although it is far from clear what consequences people are able to expect from these doses of Res, but considering all of the other potential health benefits of Res, it could be worth trying.
