Source

Methionine is found in animal products, and is important to control fat levels in the liver and the arteries.  In the absence of high animal product intake, there is a danger of not getting enough methionine.  This is the most common dietary deficiency seen in vegetarians.

Plant foods contain methionine as well: beans, seeds, onions, peanuts, lentils, and some grains.

Function; Why it is Recommended

Methionine acts as a methyl donor via SAM (S-adenosylmethionine), one of the principle sources of methyl groups in the body.  Listed as a lipotropic agent in the Merck Index, methionine is able to decrease the deposition and increase the movement of fat from the liver.

Methionine prevents fat build-up by assisting in the breakdown of fats; it detoxifies the digestive system; it is a powerful antioxidant; it reduces histamine levels; helps women excrete estrogen; helps to detoxify the liver.

Long-term use of methionine has been used to treat a variety of chronic liver conditions.
