L-Lysine
Essential amino acid the body cannot synthesize. Important for collagen production, calcium absorption, carnitine production, and immune defense against herpes.
💡 Absorption: Take on an empty stomach, separate from arginine (they compete for absorption). Well absorbed in free form.
⚠️ Caution: Generally safe. High doses (>10g) may cause diarrhea and abdominal pain. Caution in kidney disease.
