Health Benefits of Methionine
Detoxification
• Methionine plays an important role in Metabolism and detoxification (especially helpful in Liver detoxification).
Foods & Detoxification
Metabolism
• Methionine is important in single-carbon Metabolism.
• Methionine supply of Sulfur to diet is beneficial to normal Metabolism and growth.
Note:
* Sulfur deficiency leads to the body’s decrease in production and use of some anti-oxidant nutrients.
Foods & Metabolism
Musculoskeletal System
• Methionine is necessary for tissue growth and the absorption of Zinc and Selenium.

Women Health
• Methionine is very helpful to Women Health as it enhances The Liver function which in turn reduce the body’s estrogen load (considering that estrogen is cleared through The Liver). Women suffering from estrogen dominance (a condition in which the amount of estrogen in the body is too high compared to that of progesterone) benefit greatly.
