Methionine

L-Methionine

L-Methionine (methionine) is a sulfur-bearing essential amino acid, which means that it cannot be manufactured by the body and must be obtained through diet or by supplementation. L-methionine is an antioxidant found in meat and dairy products and supplementing with it is especially recommended for people on a vegetarian diet.

L-Methionine acts as a methyl donor in biochemical pathways and can be converted to SAMe (S-adenosyl methionine), a natural compound that supports liver function, healthy joints, and is necessary for normal brain function. S-adenosyl methionine, a precursor to phosphatidyl choline and creatine. Phosphatidyl choline, an important component of cell membranes, supports healthy brain function. Creatine forms creatine phosphate, a high-energy compound found in high concentration in the muscles. Creatine phosphate helps regenerate ATP during exercise, providing energy for short bursts of maximal muscle power.

In the body, methionine is converted to L-Cysteine and is potentially beneficial in liver detoxification and in neutralizing toxins. L-Cysteine is a component of the cellular antioxidant glutathione, an important antioxidant molecule in the body which assists in natural detoxification processes. L-methionine is also a transporter of the antioxidant mineral, selenium.

L-Methionine has been shown to support healthy copper and lead serum levels, liver fat metabolism, healthy skin and nails, and energy production. High purity, free form l-methionine is well tolerated.
L-Methionine is one of the nine essential Amino Acids necessary for balanced nutrition and good health. Amino Acids provide the crucial building blocks for protein. Protein plays a role in constructing and maintaining the critical structures and functions of the body.
