Amino acids can be obtained from protein-rich foods such as meat, fish, eggs, dairy products, and plant-based sources like beans, lentils, and soy products. However, amino acids can also be taken in the form of supplements or medical products.
Amino acid supplements are available in various forms, including tablets, capsules, powders, and liquids. These supplements may contain a combination of different amino acids or specific individual amino acids, depending on the intended use.
