Description
A non-essential amino acid with a mild sweet taste, used as a flavor modifier in food, as an ingredient in sports-nutrition supplements, and in pharmaceutical applications including parenteral nutrition.
White crystalline powder. Highly water-soluble. Distinguished from beta-alanine (catalog id 8075) by structure: L-Alanine is the alpha-amino acid; beta-alanine has the amino group on the beta-carbon.
We supply food-grade and pharmaceutical-grade L-Alanine from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production.
Common market grades include Standard Food Grade (FCC compliant), Pharmaceutical Grade meeting BP/USP/EP/JP specifications, and pre-blended L-Alanine systems for sports-nutrition formulations.
Bulk and reduced-MOQ shipments. Batch-level COA covering assay, specific rotation, related amino acids, heavy metals, and microbiology.
Introduction
L-Alanine is a non-essential amino acid that the body produces through transamination from pyruvate. The molecule has the simplest non-hydrogen side chain (methyl group) among proteinogenic amino acids.
Industrial production proceeds by submerged aerobic fermentation using engineered Escherichia coli or Corynebacterium glutamicum strains.
Recognized as a permitted food ingredient by the U.S. FDA, the European Food Safety Authority, and equivalent regulators worldwide. Listed in BP, USP, EP, and JP pharmacopoeias.
The mild sweet taste of L-Alanine supports specialty food-flavoring applications where conventional sweeteners would interact unfavorably with other formulation components. Use levels in food applications are typically 0.05 to 0.5 percent, providing subtle sweetness modulation without functioning as a primary sweetener.
Strategic positioning serves food flavoring, pharmaceutical, supplement, and cosmetic applications across the spectrum, without a single dominant high-volume use.
Where it is used

- Pharmaceutical applications: parenteral nutrition formulas
- Dietary supplements: amino-acid blend formulations
- Sports nutrition: pre-workout and recovery formulations
- Cosmetic skincare: amino-acid skincare and moisturizing formulations
- Specialty pet food and palatability applications
- Research and analytical applications
