L-histidine is one of the 10 essential amino acids for infants. Most lists of amino acids classify L-histidine as an essential amino acid; however, it has never been clear if L-histidine is an essential amino acid for adults. Even though L-histidine is synthesized by the body, sufficient quantities may not be made to meet the physiological requirements imposed by certain stress or disease situations.
L-histidine plays a key role in production of red and white blood cells. It has been reported that rheumatoid arthritis sufferers have abnormally low blood levels of L-histidine. A pilot clinical study with RA patients show mixed results but still enough to warrant further research.

L-histidine is a semi-essential amino acids. It is particularly important for the growth of infants and young children and animals. It can be used to produce biochemical reagents and drugs for heart disease, anemia, rheumatoid arthritis, etc.
