8 Best Supplements to Boost Testosterone Levels

1- D-Aspartic acid

D-Aspartic acid is a natural amino acid that can boost low testosterone levels. Research suggests that the primary way it works is by increasing follicle-stimulating hormone and luteinizing hormone. This is important because the luteinizing 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 hormone and testosterone production and transportation around the body.

It may also aid in sperm quality and production. One 90-day study gave D-aspartic acid to men with impaired sperm production. Sperm count doubled from 8.2 million sperm per ml to 16.5 million sperm per ml. In another study, athletic men with healthy testosterone levels followed a 28-day weight-lifting routine. Half of them were given 3 grams of D-aspartic acid per day. Both groups showed significantly increased strength and muscle mass. However, there was no increase in testosterone in the D-aspartic acid group. These findings suggest that taking D-aspartic acid may be most beneficial in people with low testosterone or impaired sexual function, but not necessarily in individuals with normal testosterone levels.

2- Vitamin D

Vitamin D is a fat-soluble vitamin produced in the skin when exposed to sunlight. Its active form functions as a steroid hormone in the bodyNowadays, a large portion of the population has very little exposure to sunlight, resulting in low or deficient levels of vitamin D.Increasing your vitamin D stores may boost testosterone and improve other related health measures, such as sperm quality.

One study found a close correlation between vitamin D deficiency and low testosterone. When participants spent more time in the summer sun, and their vitamin D levels increased, so did their testosterone levels. In a year-long study, 65 men were split into two groups. Half of them took 3,300 IU of vitamin D every day. The supplement group’s vitamin D levels doubled, and their testosterone levels increased by around 20%, from 10.7 nmol/l to 13.4 nmol/l.To get more vitamin D, increase your sun exposure. You can also take around 3,000 IU of vitamin D3 daily and eat more vitamin-D-rich foods.

3- Tribulus Terrestris

Tribulus (Tribulus Terrestris) is an herb that has been used for centuries in herbal medicine. Most of the current research on it consists of animal studies, which show improved sex drive and increased testosterone levels. One 90-day study in men with erectile dysfunction found that taking Tribulus improved self-reported ratings of sexual health and increased testosterone levels by 16%.

However, the current research has shown no benefit of taking Tribulus for young elite athletes and healthy individuals with normal testosterone levels. As with most other testosterone boosters, it appears Tribulus has benefits in low testosterone or impaired sexual function but does not appear to increase testosterone in individuals with normal or healthy levels.

4- Fenu Greek

Fenugreek is another popular herb-based testosterone booster. Some research suggests it may work by reducing the enzymes that convert testosterone into estrogen. One of the most comprehensive studies tested two groups of 15 college men over eight weeks. All 30 participants performed resistance training four times a week, but only the participants in one group received 500 mg of fenugreek per day.

Both free and total testosterone levels increased in the fenugreek group, whereas the group that only weight trained experienced a slight decline. Those who took fenugreek also experienced a more considerable increase in fat loss and strength. Another study examined how fenugreek affects sexual function and quality of life. The researchers provided 60 healthy men between 25 and 52 years old with either 600 mg of fenugreek or an empty placebo pill every day for six weeks.

5- Ginger

Ginger is a common household spice that has played a role in alternative medicine for centuries. It has many health benefits, with intense research showing it may reduce inflammation and maybe even boost testosterone levels. Several studies in rats have found ginger has positive effects on testosterone levels and sexual function. In one 30-day study, researchers found ginger increased testosterone and luteinizing hormone in diabetic rats.

In another study, the rats’ testosterone levels nearly doubled. A third study found more significant increases in testosterone when folded the amount of ginger they gave the rats. In one of the few human studies, 75 infertile men were given a daily ginger supplement. After three months, they experienced a 17% increase in testosterone levels, and their luteinizing hormone had nearly doubled

When measuring sperm health, the researchers found several improvements, including a 16% increase in sperm count. Although it is still early in the research on ginger and testosterone, eating ginger is very safe and provides numerous other health benefits.


Dehydroepiandrosterone (DHEA) is a naturally occurring hormone within the body. It plays a role in boosting testosterone and controlling estrogen levels. Based on its biological effects, DHEA has become a popular way to boost testosterone. Out of all the testosterone boosting supplements, DHEA has the best and most extensive research behind it.

Several studies have found that 50-100 mg of DHEA per day can boost testosterone levels by up to 20% compared to a placebo. However, as with most supplements, the results are mixed. Several other studies used similar dosing protocols and found no effect.

For this reason, the effects of DHEA on testosterone levels aren’t apparent. Nevertheless, DHEA use is banned in professional sports and, therefore, not suitable for competitive athletes. As with some of the other supplements, it may benefit those with low DHEA or testosterone levels.

7- Zinc

Zinc is an aphrodisiac, and zinc is an essential mineral involved in more than 100 chemical processes within the body. As with vitamin D, zinc levels within the body have been closely associated with testosterone levels.

One study that measured this association found that restricting zinc intake from foods lowered testosterone levels in healthy men. As expected, zinc supplements in zinc-deficient men also increased testosterone levels. Another study measured the effects of zinc on infertile men with either low or normal testosterone levels.

The researchers found significant benefits for those with low levels, including increased testosterone and sperm count. However, they found no additional benefit for men with normal levels. In elite wrestlers, taking zinc each day also helped reduce a decline in testosterone levels following a 4-week high-intensity training regimen.

In light of these studies, zinc may boost testosterone levels if you have low testosterone or are deficient in zinc. Taking zinc also appears helpful if you struggle to recover from high-intensity exercise.

8:- Ashwagandha

Also known as Withania somnifera, ashwagandha is another herb used in ancient Indian medicine. Ashwagandha is primarily an adaptogen, meaning it helps your body handle stress and anxiety.

One study tested its benefits on sperm quality in infertile men, who received 5 grams per day over three months. The men in this study had a 10-22% increase in testosterone levels. Besides, the partners of 14% of participants became pregnant. Another study suggests ashwagandha increases exercise performance, strength, and fat loss while also significantly boosting testosterone levels.

It seems likely that ashwagandha could help increase testosterone levels in stressed individuals, possibly by reducing the stress hormone cortisol.
