Food-grade L-alanine is a non-essential amino acid, meaning the human body can synthesize it, and it is also obtained through dietary sources. It plays a significant role in protein synthesis, serving as a building block for various proteins in the body. L-alanine is involved in glucose metabolism, and its conversion to pyruvate contributes to energy production. As a food-grade ingredient, L-alanine undergoes quality control measures to ensure its safety and efficacy in various applications. It is found naturally in protein-rich foods such as meat, poultry, and dairy products. While not as commonly supplemented as essential amino acids, L-alanine's role in supporting overall protein function and energy metabolism makes it a relevant component in the formulation of certain food and dietary supplement products.
