In shortBCAA is the collective term for branched-chain amino acids: L-Leucine (CAS 61-90-5), L-Isoleucine (73-32-5), and L-Valine (72-18-4). A 2:1:1 ratio is common, widely formulated into sports-nutrition products.
What BCAA is
BCAAs are leucine, isoleucine, and valine. Most are produced by fermentation and blended in ratios such as 2:1:1 or 4:1:1.
Form & solubility
Leucine dissolves poorly in water, so for drink applications an instant (granulated) type is easier to handle. Choose the form—powder, stick, tablet—per dosage form.
Sourcing points
Confirm blend ratio, solubility, and particle size, and select per use (drink/tablet). FONTIA offers various amino acid ingredients and BCAA blends.
FAQ
What is the 2:1:1 ratio?
It is the mass ratio of leucine:isoleucine:valine. Depending on use, 4:1:1 and others are also available.
Any caution for drinks?
Since leucine is poorly soluble, an instant (granulated) type is effective.
Single amino acid vs. blend?
Single grades offer formulation flexibility; blends reduce blending and dissolution effort.
