Other Proposed Uses

Histidine is a semiessential amino acid, which means your body normally makes as much as it needs. Like most other amino acids, histidine is used to make proteins and enzymes. The body also uses histidine to make histamine, the culprit behind the swelling and itching you feel in an allergic reaction.
It appears that people with rheumatoid arthritis may have low levels of histidine in their blood. This has led to some speculation that histidine supplements might be a good treatment for this kind of arthritis, but so far no studies have confirmed this.
 

Therapeutic Uses

Although individuals with rheumatoid arthritis appear to have reduced levels of histidine in the blood, 1,2 this by itself doesn't prove that taking histidine will help. One study designed to evaluate this question directly found no significant benefit. 3
