Fatigue Delay & Muscle Preservation
Valine plays a key role in preventing central nervous system fatigue by competing with tryptophan for entry into the brain - helping you stay mentally sharp during long training blocks. It also supports muscle tissue repair and coordination, making it especially valuable for athletes doing back-to-back sessions or high-volume training weeks, as part of post workout repair by the body.
It’s not just about energy - it’s also about protection. Valine helps preserve lean muscle by limiting protein breakdown during tough workouts or when in a calorie deficit. It’s the quiet workhorse of the BCAA trio.
In short: Fights fatigue and preserves muscle during long or intense training.
