Official title
Safety of Graded-Dose of Histidine as Determined by Circulating Analytes, Sleep Records, Physical Activity, Anthropometric Measurements, and Mood
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Histidine is an essential amino acid with health benefits that include anti-inflammatory, anti-oxidant, glucoregulatory, and weight management. The current expert opinion for histidine intake is 8 and 12 mg/(kg body weight per day), an estimate that was extrapolated from the infant requirement for histidine. Further, the clinical safety of histidine supplementation above the average dietary intake has not been determined.The overarching objectives are to 1) measure the safety of histidine supplementation and 2) measure the potential benefits of histidine at doses above the average intake and current recommendation in a healthy adult population.
