L-Methionine is an essential amino acid. It contains sulfur, is soluble in water and is important to many of the processes our body goes through on a daily basis. Since it is essential, it must be supplied from the diet and cannot be made by the body. Supplements are available from a variety of companies, however, supplementation is not recommended for any Methionine amino acid unless a doctor advises it.

List of Ingredients

L-Methionine is an amino acid and is generally the only ingredient in supplements. There may be other inactive ingredients depending on the capsule or delivery method.

Product Features

As an essential amino acid, the L-Methionine antioxidant is required by the body to do certain things to keep itself healthy. It plays a key role in breaking down fats and getting rid of free radicals that cause skin damage and cancer. The main source of L-Methionine is in cheeses and other diary products, but it can also be found in some fruits and vegetables. Adults should get at least 13 mg per day for a healthy dose, but in reality, most adults get more than this from the food sources they eat. Since the daily requirement is commonly exceeded through natural food sources, supplementing is not recommended.

L-Methionine is necessary for a healthy body, and technically plays a small role in the prevention of weight gain because of how it breaks down fats. This does not mean however, people should supplement with it or use it in hopes of losing weight. It’s not a weight loss aid, and is not safe to use as a supplement because we get more than we need each day from the food we eat. If you supplement L-Methionine, make sure you are doing so under the direction of your doctor and following his or her orders exactly as they are prescribed.
