Amino acids are the building blocks your body uses to build and repair muscle, produce energy, and support recovery after exercise. Whether you're training regularly, recovering from intense workouts, or looking to understand how protein breaks down in your body, amino acids matter to how your muscles perform and adapt. This category covers what amino acids do, which ones affect performance most, and how to get them through food or supplements.

The articles here answer practical questions: which amino acids support muscle growth and endurance, how much you actually need, how to choose between whole protein sources and isolated amino acid products, and how to time them around your training. You'll also find guidance on reading labels, spotting quality products, and understanding the real difference between different types of amino acid supplements.
