What’s in Provacyl?
Provacyl is a proprietary blend of herbal extracts and supplements designed for men, andcontains muira pauma extract, ginkgo biloba, chaste berry, acai fruit, panax gingseng, tribulus terrestris, Swedish flower pollen, Long Jack, anterior pituitary and hypothalamic extracts, DHEA, and a blend of amino acids.
Though many of the individual ingredients in Provacyl have been studied, it is unclear whether any scientific studies have been performed to support the claims of Provacyl.
What the Science Says
Muira pauma and tribulus terrestris are herbs that claim to improve sexual performance. These claims, however, are not well substantiated in the scientific literature. Ginkgo biloba is a well-studied herb that does show anti-inflammatory and antioxidant effects and improves blood flow. Studies on ginkgo biloba on sexual dysfunction have not consistently found statistically significantly beneficial effects, however, compared to individuals receiving a placebo. Beneficial effects for some study participants have been demonstrated, however.
Panex ginseng is also an herb that shows some proven health benefits. Mild to moderate improvement in erectile dysfuntion has been shown in a double blind placebo controlled study in doses of 1000 mg three times a day, a far higher dose that available in Provacyl.
Acai fruit does possess antioxidant activity, but claims in boosting hormone levels and enhancing sexual performance are unfounded at this time. Swedish flower pollen has been shown in medical studies to improve urinary flow and reduce inflammation of the prostate. Long Jack does not appear to have any proven benefits on hormone or sexual enhancement.
What About the Amino Acid Blends?
Arginine is claimed to boost growth hormone levels. This is largely based on a study in which 1000 mg of arginine given intravenously improved growth hormone production. An oral dose would need to be much higher, in the range of 5,000 to 9,000 mg, which is much higher than the dose available in Provacyl. Arginine does, however, increase nitric oxide production, which improves blood flow, and in moderate doses can, therefore, improve erectile dysfunction.
Is DHEA Beneficial?
DHEA is the most abundant hormone in the body and precursor to testosterone and estrogen. DHEA levels begin to decline in our 20’s. In males, though, supplementation with DHEA is more likely to get converted to estrogen. Testosterone levels are more likely to increase in females taking DHEA than males. The dose of DHEA in ProvacylTM would not be expected to increase testosterone production appreciably in males.
What are the Alternatives to Provacyl?
If you’re suffering from those symptoms that Provacyl claims to address, you should seek attention from an Age Management, or Anti-Aging physician, specializing in hormone replacement. Growth hormone levels frequently improve in response to a low-glycemic diet and exercise that includes high intensity interval training and strength training. Also, optimal levels of testosterone will increase growth hormone levels.
For testosterone deficient men, the best way to improve energy, erectile dysfunction, sexual performance, and mental concentration would be to receive testosterone supplementation by a knowledgeable physician. The cost of testosterone is modest, and with a prescription plan would be similar to the monthly cost of Provacyl.
