Methionine is an essential amino acid found in protein food sources such as meat and dairy products. Your body cannot produce methionine, so you must get it from food or supplements. It is important for many functions in the body, including building new proteins, making DNA, and normal tissue growth and repair.
There is no recommended dose for methionine supplements, but you should get about 14 milligrams (mg) per kilogram (kg) of body weight per day from the food you eat. Methionine supplements are commonly used to treat a variety of infections and illnesses, but scientific research supporting these uses is limited. However, methionine is considered effective in treating Tylenol (acetaminophen) poisoning.
Some people worry that methionine supplements may do more harm than good because of the various side effects associated with taking too much methionine.
This article will explore the evidence-based uses of methionine, side effects, precautions, recommended dosage, and food sources of this essential amino acid.
