 Methionine is an essential amino acid that helps the body
process and eliminate fat. It contains sulfur, a substance that is
required for the production of the body most abundant natural
antioxidant, glutathione. The body also needs plenty of
methionineto produce two other sulfur-containing amino
acids,cysteine and taurine  which help the body eliminate
toxins, build strong, healthy tissues, and promote cardiovascular
health.
Methionine is a lipotropic, or a chemical substance that helps the
liver process fats (lipids). Other lipotropics include
choline,inositol, and betaine (trimethylglycine), all of which help
prevent the accumulation of fat in the liver and thus ensure normal
liver function, which is essential for the elimination of toxins
from the body. Methionine also supports liver function by
regulating glutathione supplies;qlutathione is needed to help
neutralize toxins in the liver.
Methionine is needed to make creatine a nutrient naturally found
primarily in muscle tissue that provides the energy our muscles
need to move, and has been found to boost athletic performance
during short, intense workouts. Creatine is necessary for all
muscular function, and thus supports normal functioning of the
heart and circulatory system.
Methionine is essential for the formation of healthy collagen used
to form skin, nails, and connective tissue, and helps reduce the
level of inflammatory histamines in the body. People with
conditions linked to excessive histamine production, such as
arthritis and chronic allergies, may benefit from methionine
supplementation.Â
People with AIDS have low levels of methionine. Although research
in this area is preliminary, some researchers suggest that
methionine deficiency may be linked to certain aspects of the
disease process, such as deterioration that occurs in the nervous
system that can cause dementia. One study reported that taking just
6 grams of methionine each day can improve memory recall in people
with AIDS.
Preliminary research indicates that methionine may also help treat
symptoms of pancreatitis and Parkinsons disease. It has also been
found to be helpful for treatment of urinary tract infections; like
cranberry, methionine helps prevent bacteria from sticking to and
proliferating in the walls of the urinary tract.
Recently a form of methionine supplement called SAMe
(S-adenosylmethionine) has become available. Research has shown
that SAMe is effective for treatment of arthritis and some forms of
depression. The average dose is **0 milligrams three times daily,
and it works best when taken with a B-complex vitamin. You can also
obtain SAMe at any local pharmacy or health food store.
Methionine is an essential vitamin, which means it must be obtained
through dietary sources. It is found in a variety of natural food
sources, including beans, eggs, fish, garlic, lentils, meat,
onions, soybeans, seeds, and yogurt. It is also available at health
food stores and from online distributors in capsule and powder
forms.
Average-size adults require approximately **0 to 1,**0 milligrams
of methionine per day. It is important to note that excessive
methionine intake, together with inadequate intake of folic
acid,vtamin B6Â and vitamin B*2 can increase the conversion of
methionine to homocysteine substance linked to cardiovascular
disease. However, supplementation of up to 2 grams of methionine
daily for long periods of time has not been reported to cause any
serious side
