Testosterone is the primary male hormone; however, it is also very important for women. It is crucial to reaching optimal muscle gain, fat loss and being healthy overall. The bad news is that testosterone levels in men nowadays are much lower than in their predecessors, partly due to the generally unhealthy modern way of living. Testosterone booster products are natural supplements which can greatly increase testosterone levels.
They do that by either increasing production of testosterone directly or of some other closely related hormones, or by preventing the process of aromatization, which is the conversion of testosterone into estrogen. We present to you the 8 best testosterone boosters:
1. D-Aspartic acid
D-Aspartic acid is an amino acid which can naturally increase low levels of testosterone. Studies suggest that it primarily works by increasing the FSH (Follicle-Stimulating Hormone) and LH (Luteinizing Hormone). This is key since the LH causes the Leydig cells found in the testes to release more testosterone. Studies in humans and animals have found that as little as twelve days of taking D-Aspartic acid can increase LH levels as well as testosterone production and make its transportation across the body more efficient. This acid can also help with sperm quality and production. In a study that lasted 90 days, scientists gave D-aspartic acid to male subjects with impaired sperm production. At the end of the study, their sperm count practically doubled, from 8 million sperm per ml to 16 million.
Another study included athletic men who had healthy levels of testosterone and who were put on a 30-day training routine. Half of them took 4 grams of D-aspartic acid a day. The two groups exhibited a significant increase in muscle size and strength. However, the group that didn’t take D-aspartic acid did not show an increase in testosterone levels. A conclusion can be drawn that taking D-aspartic acid might be the most beneficial in individuals who have low testosterone levels or those who suffer from impaired sexual function, but not necessarily in people who have normal levels of testosterone. The bottom line is that the acid works by stimulating the release of some key testosterone-related hormones. 2-3 gram doses have been proven to be effective in people who have low testosterone levels.
2. Vitamin D
Vitamin D is a fat-soluble vitamin released in your skin when exposed to the sun. In its active form it functions as a steroid hormone in your body. In modern times, a majority of the population has little exposure to sunlight, which results in low or deficient vitamin D levels. Increasing vitamin D might increase testosterone levels and increase other health-related measurements, like sperm quality. A stufy found that there is a close link between vitamin D deficiency and decreased testosterone levels. When the subjects in the study were exposed to the summer sun and their vitamin D production increased, this resulted in increased testosterone levels.
There was a study done in the course of several years, where 60 men were split into two groups. The first group took 3,300 IU of vitamin D every day. This group experienced a double increase in their vitamin D levels and their testosterone increased by 20%, from 10.6 nmol/l to 13.3 nmol/l. In order to get more of this vitamin, increase your exposure to sunlight. As an alternative, you can take approximately 3000 IU of vitamin D3 daily and consume foods rich in vitamin D. This is an important vitamin which can greatly increase your testosterone levels, especially if you are deficient in it.
3. Tribulus Terrestris
Tribulus is a plant that’s been used in many countries around the world for medical purposes for many centuries. The majority of the research nowadays is concentrated on animal studies, which repeatedly show increased libido and testosterone levels. A 90-day study which observed men who suffered from erectile dysfunction found that consuming tribulus increased the self-reported perceived ratings of the participants’ libido and increased their testosterone levels by 15%. But, there are also other studies which haven’t shown any benefit of consuming tribulus for young advanced athletes and healthy people with normal testosterone levels.
The same as many other testosterone boosters, it seems that tribulus offers benefits only to those who have low testosterone levels of suffer from impaired sexual function, and doesn’t help with increasing testosterone levels in people with normal levels. The bottom line is that tribulus can help men with their sex drive and improve their sperm count and quality, as well as raise testosterone levels in men who suffer from erectile dysfunction.
