  • Flavor enhancement: Amino acids like glycine and alanine can be used to improve flavor and mouthfeel.
  • Preservation: Cysteine is commonly added to juice products as an antioxidant.
  • Nutritional improvement: Certain amino acids can be added to plant-based foods to supplement limiting nutrients and enhance overall nutritional value.

Many energy drinks include amino acids and taurine, which play important roles in energy metabolism. Tyrosine, a non-essential amino acid, is involved in the synthesis of neurotransmitters that are essential for neural signaling and mood regulation.

Adequate amino acid intake supports the healthy growth of intestinal villi and deeper crypts, improving nutrient absorption. This enhances feed efficiency and growth rates in broilers and laying hens.

  • Promote photosynthesis and improve light energy utilization.
  • Enhance resistance to environmental stress, such as drought or salinity.
  • Function as growth regulators to stimulate root development, flowering, and fruiting.
  • Serve as buffering agents in fertilizers or nutrient solutions to help maintain proper pH levels.

Essential amino acids, including lysine, valine, and leucine, cannot be synthesized by the body and must be obtained through diet. Supplementation is especially important for athletes, the elderly, or those with metabolic disorders, helping maintain muscle mass, promote protein synthesis, and boost immune function.

Amino acids contribute to the development and performance of sustained-release injections by supporting formulation structure, suspension behavior, drug diffusion, and biocompatibility.
