Sports Performance

Key Benefits

Reduces exercise-induced muscle breakdown
Decreases perceived exertion
Supports recovery during training
Useful during fasted training

How It Works

Branched-chain amino acids (leucine, isoleucine, valine) bypass liver metabolism, going directly to muscle. Leucine activates mTOR for muscle protein synthesis. BCAAs reduce serotonin production during exercise (competing with tryptophan for brain entry), reducing fatigue perception.

Dosage & Timing

Recommended Dosage

5-10 g during or around training

Best Time to Take

Intra-workout or pre-workout, especially during fasted training

Recommended Form

2:1:1 ratio (leucine:isoleucine:valine) powder

Side Effects

Generally safe. Rare GI discomfort. Unnecessary if protein intake is adequate (>1.6g/kg).

Drug Interactions

May interact with diabetes medications (BCAAs affect insulin). May be problematic in maple syrup urine disease.

What Does The Research Say?

Benefits are most pronounced during fasted training or inadequate protein intake. If consuming sufficient protein (especially whey), additional BCAAs provide minimal benefit. Research shows reduced DOMS and fatigue during prolonged exercise.
