Amino acids are the building blocks of proteins — essential for muscle repair, enzymes & hormones, immune function, and neurotransmitters. Of the 20 standard amino acids used in human proteins, 9 are essential (must come from food), 7 are conditionally essential (needs rise in stress/illness/growth), and the rest are non-essential (normally synthesised by the body).
✅ Balanced intake → better recovery, resilience, and metabolic health.
❌ Imbalanced/prolonged low intake → reduced performance, poor healing, low lean mass.
