About Isoleucine
Essential branched-chain amino acid (BCAA). Studied mainly in combination with leucine and valine. Plays a role in glucose uptake into muscle tissue and energy regulation during exercise.
What Isoleucine supports
- Supports glucose uptake into muscle for exercise fuel
- Supports endurance and post-exercise recovery
How much Isoleucine to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
1500–4000
mg
Typically dosed alongside other BCAAs in a 2:1:1 ratio (leucine:isoleucine:valine).
Clinical evidence
Moderate clinical evidence. Studied mainly in combination with other BCAAs; limited standalone clinical data
