Testosterone is the key male sex bodily hormone, but is also essential for females. It plays an essential role in muscle development, fat loss, and optimal health. Nevertheless, testosterone levels in guys are now lower than ever before, partly caused by the unhealthy present day lifestyle. Testosterone boosters are natural supplements that may increase your testosterone levels. They work by directly increasing testosterone or related hormones, but some work by preventing testosterone from being converted into estrogen. Some of those boosters have been scientifically verified in human studies.
Here are the eight best testosterone boosting supplements. D Aspartic Acid – D Aspartic acid is a natural amino acid that may boost low testosterone levels. Studies suggest that the main way it works is by increasing follicle stimulating bodily hormone and luteinizing hormone. This is very important, because luteinizing bodily hormone makes the Leydig cells in the testes produce more testosterone. Initial research in animals and humans has found that as little as 12 days of D aspartic acid seems to increase luteinizing bodily hormone as well as testosterone production and transportation around the body. It might also aid in sperm quality and production.
One 90 day study gave D aspartic acid to men with impaired sperm production. Sperm count doubled, rising from 8.2 million sperm per ml to 16.5 million sperm per ml. In another study, athletic men with healthful testosterone levels followed a 28 day weight lifting routine. 50% of them were given 3 grams of D aspartic acid per day. Both groups showed significantly increased strength and muscle mass. Nevertheless, there was no increase in testosterone in the D aspartic acid group. Taken together, these results suggest that taking D aspartic acid can be most beneficial in individuals with low testosterone or in those with impaired sexual function, but not necessarily in people with normal testosterone levels.
Bottom Line: D Aspartic acid might work by stimulating some key testosterone producing hormones. Doses of 23 grams seem to be effective for all those who’re testosterone deficient. D vitamin – D vitamin is a fat soluble vitamin produced in the skin when exposed to sunlight. Its active form functions as a steroid bodily hormone within the body. These days, a large part of people has very little exposure to sunlight, leading to low or deficient levels of vitamin D. Increasing your D vitamin stores might boost testosterone and improve other related health measures, like sperm quality. One study found a close correlation between D vitamin deficiency and low testosterone.
When participants spent more time in the summer sun and their D vitamin levels increased, so did their testosterone levels. In a year long study, 65 men were divided into 2 groups. 50% of them took 3, 300 IU of D vitamin every day. The supplement groups D vitamin levels doubled and their testosterone levels increased by around 20%, from 10.7 nmol\/l to 13.4 nmol\/l. To get more D vitamin, increase your sun exposure.
