One study that evaluated the effects of yohimbine supplementation on body composition (muscle mass, body mass, etc.) and exercise performance in professional soccer players found that body fat percentage/fat mass significantly decreased in the yohimbine group compared to the placebo group. However, supplementation with yohimbine did not significantly alter overall body mass, muscle mass, or performance indicators. (10) Other studies, however, have found that people do tend to experience increases in energy and alertness when taking yohimbe, sometimes even so much that it causes symptoms of anxiety or restlessness (much like caffeine does).
Niacin or Vitamin B3 has proved to be helpful in improving both lipid levels and cholesterol among patients suffering from the problem of atherosclerosis i.e. accumulation of waste fats across the walls of the human blood vessel. Because of this, Niacin is helpful in the treatment of erectile dysfunction, as ED and atherosclerosis have more or less similar causes.
Zinc distributes all over the body, so it’s difficult to test through a blood test. If you have problems with erectile dysfunction or suspect that you might have a zinc deficiency, talk with your doctor. A medical professional will be able to check your testosterone level and determine if using zinc supplements to treat your ED is an appropriate course of action.
Though higher doses of zinc reduce libido, supplementation with a medium dose (5 mg/day) has some beneficial effect on the sexual competence of adult male rats. The major significant effects of this dose of zinc are prolongation of ejaculatory latency without disturbing sexual arousability, motivation, penile erection and sex vigor. Also, the partner preference index of the 5 mg/day group was positive and comparable to the controls. A positive partner preference index is indicative of unchanged sexual interest of males. These results confirmed that libido and sexual interest are not affected by zinc supplementation with a 5 mg/day dose. However, mild reduction in percentage of intromission was observed in this group and it is postulated that this may be situational rather than an effect of supplemented zinc. This is based on our observation where mild rejection by the females at the initial phase of the behavior led some males to refrain from sexual activity.
What if we look at erectile dysfunction as something that can be addressed as a condition other than a “pill for every ill”. What if we actually look at a nutrient level that directly correlates to a medical condition and follow the science to give a directive on its recommendation? Well it turns out taking a simple zinc supplement won’t help 100% of the time, but it certainly helps some of the time.
The development of successful sexual behavior involves not only important neuroendocrine and local genital changes that begin at puberty, but also psychological and social influences that occur both before and after puberty.[7,8] Sexual behavior in males is regulated mainly by internal patterns of hormones; i.e. T, progesterone and PRL. These hormones are modulated by the male interactions with the social environment.
Low levels of zinc can be the cause for a variety of health-related problems. Zinc is a key mineral that cells use to metabolize nutrients. Immune function, DNA and protein production, and cell division are all related to zinc levels in the body. Zinc also enables the male body to produce testosterone. Because of this, your levels of zinc may affect erectile dysfunction.
