What is L-Isoleucine?
L-Isoleucine is one of the three branched-chain amino acids (BCAAs) and an essential nutrient the body cannot produce on its own. It plays a central role in muscle tissue repair, energy production, and hemoglobin formation. Unlike L-Leucine which is highly anabolic, L-Isoleucine is more glucogenic, helping the body regulate blood sugar levels and sustain energy during prolonged exercise or stress.
L-Isoleucine is a key ingredient in sports nutrition and clinical amino acid formulas for recovery and metabolic support. Our L-Isoleucine is non-GMO, vegan-friendly, and produced via microbial fermentation.

FAQs:
Q: Can Isoleucine be taken alone?
A: While it has benefits on its own, it’s typically combined with Leucine and Valine for optimal muscle support.
Q: Is it suitable for vegans?
A: Yes, it is 100% vegan and derived from fermentation of plant-based materials.
Q: Is it safe for daily consumption?
A: Yes, especially in regulated doses as part of protein or amino acid intake.
