What Are Testosterone Boosters?

Testosterone boosters cover a wide range of supplements but what they all have in common is that they work to raise your levels of testosterone. By wide range, all that means is men and their levels are all different and for some, it requires a gentle push in the upward direction.

For others, the need for a supplement is a bit more drastic thus requiring something a bit more powerful. All in all, testosterone boosters work to raise your testosterone levels to help with growth and development, performance and a number of bodily functions that keep us moving efficiently (1).

Benefits Of Testosterone Boosters

When it comes to the benefits of testosterone boosters, you won’t want to ignore them. With the ability to really work wonders on many areas of your body, a good test booster can:

Increase strength and muscle growth: Since testosterone improves protein synthesis, you will gain muscle faster, thus translating that into more strength (2).

Burn stored fat for a shredded aesthetic: Combined with exercise, increased testosterone can help shed away unwanted body fat by balancing out the levels of testosterone and estrogen. By increasing muscle mass and burning fat, your body composition will change to show that shredded physique.

Boost sex drive: The more testosterone you have, the greater the sex drive as this will increase libido and boost overall sexual function (3).

Improve mood and other cognitive abilities: Since testosterone helps boost energy levels, you will feel less tired and more alert. By increasing oxygen around your body and brain, your mood will improve and you will be sharper with decisions (4).

Key Ingredients

Here are some key ingredients to look for in a testosterone booster. While many companies have their own formulas, these ingredients are vital for an effective formula.

D-Aspartic Acid: This contains two amino acids in aspartic acid and L-aspartate. It will work to release hormones in the brain that can result in testosterone production (5).

Fenugreek: An ancient herb, it is rich in vitamins and minerals and can work to lower bad cholesterol, increase libido, and boost performance.

L-Arginine: Since this becomes nitric oxide in the body, it works to widen blood vessels and with increased blood flow, more nutrients hit your muscles. A great muscle building ingredient, it also encourages fat metabolism (6).

Ginseng: Another well-known herb, ginseng can boost nitric oxide levels and with this increased blood flow, there is a greater chance for the testicles to produce more testosterone.

Vitamin D3: Also known as the sunshine vitamin, this can improve testosterone levels because it is considered to be a bioidentical hormone for testosterone since it is a cholesterol-derived steroid hormone. By combining to receptors easily, it can assist in raising T levels (7).
