Testosterone is the primary male sex hormone and plays a vital role in the male reproductive system. It is responsible for developing reproductive tissues and promotes characteristics like bone density, muscle mass, and growth of body hair. This hormone is also responsible for the overall wellbeing of the human male body. The hormone is naturally secreted by testicles of the male anatomy. Although it is a natural hormone, testosterone also plays an important role in medication; for example, in the treatment for low testosterone levels in older men, certain forms of breast cancer, and to enhance physical performance mainly in athletes. The testosterone levels decrease as men age.

Most men experience a decline in testosterone levels after 40. Testosterone boosters are supplements that can help men increase testosterone levels. The best testosterone boosters have certain ingredients responsible for naturally increasing the hormone levels. D-Aspartic Acid (D-AA) is an amino acid that can make and release the hormone in the brain, which results in testosterone production. Another important ingredient is ZMA, which is a combination of zinc monomethionine aspartate, magnesium aspartate, and vitamin B6. Vitamin D, a herb called Ginseng, and fenugreek are few other ingredients that are found to be the best testosterone boosters.
