L-Lysine
Essential amino acid — the body cannot synthesise it. Critical for collagen synthesis, calcium absorption, and immune function. Clinically best known for herpes prophylaxis (HSV-1).
How it works
L-lysine is an essential amino acid the body can't make itself; it's needed for collagen formation, calcium absorption and immune function, among others. It's also known for inhibiting herpes-simplex virus replication. On a balanced diet, deficiency is rare.
Dosage
Prophylactic 1 g/day, during active HSV outbreak 1–3 g/day. Better bioavailability on an empty stomach.
Considerations
Use caution with kidney impairment. High doses may cause GI upset. Plant-based diets (especially low in legumes) can predispose to lysine deficiency.
