Cortisol is a necessary hormone produced in the adrenal glands. It is used in times of stress, both physical and mental. It is used for combatting illness, inflammation, soreness, and wounds.
Cortisol excess (through overtraining or long exercise periods)though can inhibit protein synthesis in
muscle tissue, increase bodyfat, cause bone mass loss, reduce tendon health, increase unwanted
insulin resistance, reduce growth hormone release, and adversly effect testosterone levels.
Glutamine, acetyl l-carnitine, zinc, DHEA, Prosteroids and steroids, phosphatidylserine, and Vitamin A all help to reduce or overcome cortisol effects.
