Non-essential amino acids are amino acids that the body can produce on its own, meaning they do not need to be obtained directly from food. These amino acids play vital roles in various bodily functions, including protein synthesis, hormone production, and immune system support. Examples of non-essential amino acids include alanine, aspartic acid, and glutamic acid. While the body can synthesize these amino acids, they can also be found in various food sources, such as meat, dairy, and legumes. Non-essential amino acids contribute to overall health and well-being, supporting muscle repair and growth, as well as energy production during physical activity.
