ANSWER TO QUESTION OF THE WEEK: (11/6/05)
No. The ingestion of protein and/or amino acid supplements, such as those commonly found in health food stores and groceries, can be dangerous to people with liver disease and should be avoided.
Protein supplements force the liver and kidneys to work overtime in order to get rid of the excess protein ingested. Excess protein can increase the risk of dehydration, as extra fluid is required to eliminate the byproducts of protein metabolism from the body. Also, protein supplements often contain a variety of vitamins, minerals and other food supplements which may cause dangerous excesses of these items in the body. Furthermore, they are not regulated by the FDA in the body. Protein supplements are only required for people who are malnourished and unable to obtain adequate protein intake through their regular diets.
Most of the amino acid supplements that are available over- the- counter come in quantities that are far greater than the amount the body needs. Consumption of excessive amounts of amino acids may cause serious side effects. Probably the best known example of this involves L-tryptophan, an aromatic amino acid (AAA) used as a supplement to aid sleeping. Promoted for many years as safe and natural, L-tryptophan was eventually banned for sale by the FDA in 1990 because many people who consumed this amino acid developed a serious muscle disorder. Death even occurred in some people as a result of L-tryptophan ingestion. Some other amino acid supplements are high in AAA (for example, phenyalanine, tyrosine, and tryptophan), which have been demonstrated to be detrimental to some people with liver disease. Another amino acid, methionine, may induce encephalopathy ( brain fog) in people with liver disease. Vegetables contain very little methionine, yet have a high content of the branched-chain amino acids (BCAAs- such as leucine, isoleucine, and valine). Some experts believe BCAAs are beneficial to people with encephalopathy. However, under no circumstances should any form of amino acid supplement be added to the diet of a person with liver disease.
