L-methionine is a sulfur-containing essential L-amino acid that is important in many body functions. Methionine is a dietary indispensable amino acid required for normal growth and development of humans, other mammals, and avian species. In addition to being a substrate for protein synthesis, it is an intermediate in transmethylation reactions, serving as the major methyl group donor.It must be obtained from diet and food sources since it is unable to be biosynthesized in the body. The minimum daily requirement of L-methionine for an adult male is 13 milligrams per kilogram of body weight. This quantity is normally easy to obtain from a complete diet.

FUNCTION:
1. May Help Reduce Risk of Colorectal Cancer
Methionine, along with B vitamins and other minerals, may help reduce the risk of colorectal cancer.
2. Can Lower Tremors in Parkinson's Patients
3. Builds Bone Strength
Methionine may help athletic performance (and even weight loss) due to its effects on bones.
4. Aids Weight Loss
Creatine is a substance that comes from methionine and creatine can not only help improve athletic performance, but also the body's ratio of muscle to fat.
2. Feed additives: used to improve feed quality.
3. Improve the utilization of natural proteins and promote animal development.
For example, it can increase the egg production of the chicken, increase the weight of the pig, and produce more milk for the cow.
