Methionine is an amino acid that is vital for many functions of the body. Essential amino acids cannot be synthesized by the body and therefore must be provided through diet or supplements. Methionine aids in the balancing of metabolism and growth by supplying sulfur and additional compounds, which inactivates free radicals. The right amount of Methionine in the body decreases the risk for issues involving hair growth as well as skin and nail ailments.
Methionine belongs to the lipotropic group, a collection of compounds that also contains betaine, inositol and choline and is only partly soluble in water. Methionine increases the liver’s production of lecithin, which helps to lower cholesterol levels. Methionine also protects the kidneys and reduces fat in the liver by detoxifying the body of heavy metals.
Not all types of physical activity are suitable for everyone. Users take training advice at their own personal risk.

The most well documented use of Methionine is to prevent damage from acetaminophen overdose primarily through IV or orally. It is recommended that treatment begin as soon as possible. Treatment after ten hours from the acetaminophen poisoning will be ineffective.
Methionine assists in the synthesis of certain substances in the body, including choline and epinephrine because it is a primary methyl donor. Methionine act in response to adenosine triphosphate to form S-adenosyl methionine, or what is commonly known as SAMe. SAMe is a vital part of the production of melatonin, creatine and other substances.
Methionine is also used in the treatment of endometriosis. Endometriosis occurs when endometrial tissues from the lining of the uterus begin to grow outer portion of the uterus. Methionine can also be useful in the removal of surplus estrogen from the liver, which will help patients that have a condition called estrogen dominance, which involves increased levels of estrogen.
There is some indication that Methionine can help with various other ailments, though evidence is far from conclusive. These ailments include;
Much of one’s daily Methionine needs can be obtained through diet alone. Some food that are rich in Methionine include meats, fish, garlic, brewer’s yeast, cheeses, brazil nuts, eggs, whole grains and onions to name a few. Smaller amounts of Methionine are found in vegetables and foods that are fermented, which is why consumption of whole grains is vital for vegans and vegetarians.
For cases of acetaminophen poisoning, the patient should be given 2.5 g of Methionine every 4 hours. This should be given in 4 doses to prevent severe liver damage and possible death. Note that the treatment will not be effective 10 hours after the overdose occurs and should only be given by a doctor or other medical professional.
For regular use, the World Health Organization recommends that an adult receive 1g every day. Typically this is consumed through regular diet, though occasionally deficiencies may occur.
Though most people get more than enough Methionine through their daily food intake, occasionally deficiency can happen. This is typically related to a lack of S-Adenosylmethionine.
Methionine deficiency may cause cataracts, depression, loss of color in the hair, muscle atrophy, edema (swelling), loss of fatty tissue, lesions, inhibited development in children and tiredness. In pregnancy, Methionine deficiency is suspected to cause neural tube defects in babies.
Methionine should only be used to treat acetaminophen overdose under the supervision of a doctor or other medical professional. Self-treatment with Methionine at this dose can be dangerous.
