Background

Histidine is an essential amino acid. It is not made by the body, but is consumed in foods. Amino acids are the building blocks of protein.

Histidine is involved in many different metabolic processes in the body.

People use histidine for diarrhea due to cholera infection, eczema, kidney failure, metabolic syndrome, and many other conditions, but there is no good scientific evidence to support these uses.

Safety Safety definitions

When taken by mouth: Histidine is commonly consumed as part of the diet. Histidine supplements are possibly safe when used short-term. Doses of up to 4 grams daily have been used safely for up to 12 weeks. It seems to be well-tolerated.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Histidine is commonly consumed as part of the diet. There isn't enough reliable information to know if histidine is safe to use in larger amounts as medicine when pregnant or breast-feeding. Stay on the safe side and stick to food amounts.

Folic acid deficiency: People with folic acid deficiency should avoid histidine. It can cause an unwanted chemical called formiminoglutamic acid (FIGLU) to build up in the body.

Effectiveness

Possibly effective Effectiveness definitions

An infection of the intestines that causes diarrhea (cholera). Drinking a solution containing histidine seems to reduce diarrhea in people with cholera who are also receiving antibiotics.
