! Effect of vitamin E on function of pituitary-gonadal axis in male rats and human subjects.Abstract
The role of vitamin E in the endocrine system, in particular the pituitary-gonadal axis, was studied in humans and male rats by examining the hormonal differences between vitamin E deficient and supplemented conditions. In vitamin E deficient rats, pituitary content and basal plasma level of FSH and LH were significantly lower than those of the control rats, but testicular content and basal plasma level of testosterone were not significantly changed. On the other hand, in vitamin E supplemented rats, FSH and LH content in pituitary tissue was significantly higher than that of the controls, but there was no significant rise in basal FSH and LH level in plasma. The testosterone level was significantly elevated in both testicular tissue and plasma. It was also demonstrated that basal plasma testosterone and F.T.I. were increased in normal male subjects following oral vitamin E administration and the responsiveness of plasma testosterone levels to HCG was significantly higher during vitamin E administration than before administration. These results suggest that vitamin E may play an important and potent role in hormone production in the pituitary-gonadal axis in humans and rats.http://www.ncbi.nlm..../pubmed/6816576
Fueling Testosterone and Preventing Hair Loss with Tocotrienols
Eugene, OR (PRWEB) February 15, 2008 -- Hair loss (alopecia) and low testosterone (hypogonadism) have become common problems for middle aged men. The two most popular treatments for hair loss are finasteride (Proscar/Propecia) or the topical drug minoxidil (Rogain). Patient compliance with minoxidil therapy is generally a problem, while finesteride is often associated with undesirable side-effects. By overly suppressing DHT, finasteride can lead to erectile dysfunction, gynecomastia and general impotence.
Men with low testosterone often deal with the suboptimal lifestyle, or seek the traditional hypogonadal treatment of Testosterone Replacement Therapy (TRT). However, TRT is often associated with increased hair loss, thus requiring the need for aforementioned prescription hair loss drugs. This creates a negative cycle, and further reliance on prescription medication.
Recently, the natural ingredient manufacturer Carotech obtained a US patent (7,211,247) for the hair loss prevention, and hair regrowth benefits of a mixed tocotrienol complex. For this patent, a randomized, double blind, placebo-controlled study was performed. The participants supplementing with 100mg of the tocotrienol complex had an average 42 percent increase in hair count after 5 months, with no side-effects reported. The mechanism of action appears to be unrelated to DHT levels. It's been reported that the tocotrienols may protect and replenish the hair follicle by their potent antioxidant ability.
Research with animals and humans show that tocotrienols can support testosterone production by increasing production of luteinizing hormone (LH) from the brain. LH is the hormone that signals testosterone production from the male testes. Tocotrienols have also been found to increase testicular sensitivity the effects of LH, thus increasing the testosterone response from LH.
Tocotrienols are a safe and natural supplement for men wishing to support their body's own testosterone production, while also promoting healthy hair growth. It is sold as a 30 day supply at the clinically effective hair regrowth dose.http://www.hairloss-...ienols4-08.html
