Aminos, short for amino acids, are organic compounds that serve as the building blocks of proteins. They play a crucial role in various biological processes, including the synthesis of hormones and neurotransmitters. There are 20 standard amino acids, nine of which are essential, meaning they must be obtained through diet, as the body cannot produce them. Aminos are found in a variety of foods, particularly in meat, fish, dairy, and legumes. They are also available as dietary supplements, often marketed to athletes for muscle recovery and growth. Understanding the role of aminos can help individuals make informed dietary choices to support their health and fitness goals.
