It’s normal for men’s levels of testosterone to start to decrease when they get older. In fact, testosterone levels peak in most men at around age 30 (younger than most would think) and then begin to drop off gradually. Side effects of what’s called “low T” can involve loss of youthful vigor and vitality, including a near-constant feeling of general fatigue as well as a decrease in libido and even erectile dysfunction.

For these reasons, it’s quite natural for men in this situation to want to find ways to increase their body’s levels of this male hormone. There’s much anecdotal evidence of testosterone supplements helping men to feel younger and more virile, but there are also a handful of scientific studies which confirm the beneficial effects of these supplements, so adding these supplements to your diet can certainly help to increase testosterone levels.

Some supplements directly increase the body’s supply of testosterone, whereas others indirectly increase it by inhibiting the conversion of testosterone to estrogen. We’ll talk about some of the most popular T boosting supplements currently on the market below.

Fenugreek

Fenugreek is a type of Indian herb that has been shown to increase strength in men. A study conducted at the University of Mary-Hardin-Baylor in Texas showed this to be the case, demonstrating that men taking the supplement increased their physical fitness more than another group of men not taking it.

D-Aspartic Acid

D-Aspartic Acid is an amino acid which, when taken, increases communication between the brain and the testes and so results in increased testosterone production. A study in Italy showed that men taking this supplement had an increase in testosterone levels at almost 50 % compared to men who were not taking it, and retained these high levels of T even after coming off of the supplement!

Tribulus Terrestris

Tribulus Terrestris (TT) is a type of a plant which in theory elevates luteinizing hormone, causing a chain reaction which raises testosterone levels (different hormones in the body are intricately connected). TT has been shown to increase testosterone levels and acts as an aphrodisiac, enhancing sexual performance and pleasure, so there’s more than one benefit here! You’re not going to want to consume it as is due to its bitterness, so be sure to find a supplement which includes TT.

ZMA

ZMA is a supplement which includes several ingredients, including zinc and vitamin B-6. If you look at any T-boosting diets on the Internet, you will find that both of these ingredients are considered to be critical, especially zinc. Therefore, ZMA, when taken as a supplement, can increase testosterone levels and muscular strength.

Ginger

Ginger, according to a study in the Tikrit Medical Journal, can increase testosterone levels when taken as a supplement. There are supplements which combine ginger with other T-boosting ingredients, so be sure to give those a look.

Vitamin D

Vitamin D has been shown to increase levels of testosterone. For this reason, it’s a good idea to take this is part of a supplement, and it’s often included in T-boosting diets.
