L-Arginine is an amino acid that joins in growth hormone synthesis routes and acts as a precursor in several metabolic processes. This version appears as part of a night-time amino acid mix to help overnight recovery processes.

This form shows up as part of a night-time complex and is paired with other amino acids and sleep-supporting actives to help its role in normal physiological function.

What Does L-Arginine Do?

Dr. Isidori of the University of Rome found that oral amino acid blends can sharply increase serum growth hormone, especially when taken before sleep and with exercise. L-Arginine takes part in this process within the broader AOL trio that helps to support GH activity.

Clinical context also notes that mixing sleep-supporting ingredients can align with normal sleep and recovery processes, contributing to overnight regeneration as described in the referenced work.

This supplement isn’t intended to diagnose, treat, cure, or prevent any disease.
