What is L-Histidine?

L-Histidine is an Amino Acid supplement available in 1 form.

FormulaForge carries a single form of L-Histidine, so there is no form to choose here. Forms on the market do differ in how well they absorb, which is why it is worth checking the form named on any product label.

The Form of L-Histidine We Carry

L-Histidine (as L-Histidine HCl) Preferred (Preferred Form) has a bioavailability rating of good absorption.

What the Research Shows

L-Histidine is a semi-essential amino acid and the precursor to histamine. The HCl salt form provides superior bioavailability. It is also a component of the dipeptide carnosine (beta-alanine + histidine) which provides intracellular buffering and anti-glycation activity. Research supports histidine for joint health, immune modulation, and as a zinc transport facilitator.
