L-Methionine (Methionine)


First discovered by American bacteriologist John Howard Mueller in 1921, L-methionine, or methionine, is an essential amino acid found in the body (a building block for proteins). Methionine is found in meat, fish, and dairy products. It provides an important role relating to the growth of new blood vessels. While the body produces it on its own, supplementing with L methionine has been shown to help heal wounds and those experiencing Parkinson’s, drug withdrawal, schizophrenia, radiation, copper poisoning, asthma, allergies, alcoholism, liver damage and depression.

How does it work?

The human body uses L methionine to make creatine, another type of amino acid. Additionally, L methionine contains sulfur, which is used by the body for healthy growth and metabolism, and it’s responsible for a compound known as s-adenosylmethionine or “SAMe,” which supports the proper function of the immune system; neurotransmitters like dopamine, serotonin and melatonin; and cell membranes.

In acetaminophen poisoning, methionine prevents the breakdown products of acetaminophen from damaging the liver. It may also act as an antioxidant and help to protect damaged tissues.

 

Benefits of L-Methionine:

  • May Help Reduce Risk of Colorectal Cancer

According to the Melbourne Colorectal Cancer Study, conducted in Melbourne, Australia, methionine, along with B vitamins and other minerals, may help reduce the risk of colorectal cancer. The study observed foods that were eaten as well as micronutrients, such as folate, methionine, and vitamins B6 and B12, and those with antioxidant properties like selenium, vitamins E and C, and lycopene (1).

  • Can Lower Tremors in Parkinson’s Patients

A study was conducted on 11 patients who had untreated Parkinson’s disease. Participants were treated with L methionine for periods from two weeks to six months and showed improvement in akinesia and rigidity, resulting in fewer tremors than usual. This shows methionine may be beneficial in treating Parkinson’s symptoms (2).

  • Builds Bone Strength

Methionine may help athletic performance (and even weight loss) due to its effects on bones.

  • Aids Weight Loss

Due to its role in creatine creation, methionine improved muscle to fat ratio and can help people lose weight.

  • May Support the Liver
