Rule 1 Glutamine

Rule 1 Glutamine is a 100% pure L-glutamine supplement designed to replenish what intense training depletes. As a conditionally-essential amino acid, glutamine plays a critical role in muscle protein synthesis and post-exercise recovery.

This micronized formula dissolves effortlessly into shakes, beverages, or your existing supplement stack, making it seamless to integrate into your regimen. By maintaining optimal glutamine levels, this supplement supports faster muscle repair, preserves lean tissue, and helps sustain immune function during periods of high training stress. Unflavoured and versatile, it's an evidence-backed addition for serious athletes prioritising recovery and performance.
