What Are the Dangers of Using Amino Acid Supplements?

Amino acids are naturally derived from protein in fish, milk, eggs, chicken, and meats. Supplements may help make up for a lack of amino acids from not consuming such foods. However, there are potential risks associated with amino acid supplements, some of which are life-threatening.
  1. Preexisting Conditions

    • According to the Nutritional Supplements Health Guide, amino acid supplements aggravate preexisting kidney and liver conditions and should be avoided in people with those conditions.

    Effects on Sleep

    • The metabolic and energy increases associated with amino acid supplements may cause restlessness, insomnia, and anxiety.

    Organ Damage

    • Organ damage may result when amino acid supplements are taken in high doses. High levels of amino acids can increase your heart rate and damage it over time.

    Blood Disorders

    • According to CBS Interactive Inc., taking amino acid supplements can cause a blood disorder called eosinophiliamyalgia syndrome. The disorder is related to high doses of L-tryptophan.

    Considerations

    • Amino acid supplements can benefit those who are particularly deficient in amino acids, such as vegetarians. However, you should ask a doctor before taking such supplements to help prevent adverse reactions.
