The pituitary gland and testicles produce an amino acid called D-Aspartaten, which boosts the production of hormones to increase testosterone naturally. It also increases sperm production and the Journal of Reproductive Biology and Endocrinology reported that men taking 3 grams of D-Aspartate every morning increased their testosterone.
Vitamins and minerals, whether acquired via supplements or your daily diet, play a large role in increasing testosterone. Zinc is a mineral that aids in the natural production of testosterone. High levels of zinc can be found in oysters, red meat, chicken, turkey, and other fowl. Also, beans and dairy products contain zinc.
We all know that eating a balanced diet of quality proteins, whole grains, and lots of fruits and vegetables will enable overall good health, but some specific parts of this most favorable diet also contribute to muscle growth and increase testosterone naturally.
