L-Valine, CAS No. 72-18-4, is one of the essential branched-chain amino acids (BCAAs). It cannot be synthesized by the human body and must be obtained from external sources. It mainly participates in muscle protein synthesis and energy metabolism, prioritizes energy supply for skeletal muscles, reduces muscle breakdown during exercise, delays fatigue, and accelerates muscle repair and recovery after workouts.
L-Valine has a purity of ≥99% and contains no impurities from chemical synthesis. It meets ISO, FDA, Halal, Kosher and FAMI-QS standards.
As one of the classic BCAAs, it features good water solubility and is suitable for various dosage forms including tablets, powder blends and oral liquids.
Bulk wholesale and sample testing are available. Documents such as COA and MSDS can be provided.

L-Valine cannot be produced by the body and must be ingested through foods or supplements. Valine can provide additional energy to the muscles to produce glucose, to prevent muscle weakness, and can help remove excess nitrogen from the liver, and help nitrogen transport to all parts of the body needs. Valine can be used as a nutritional supplement, may be co-formulated with other essential amino acid infusion, comprehensive amino acid preparations.
