About
L-Lysine is an essential amino acid that may support hair health by enhancing iron and zinc absorption — two minerals critical for normal hair cycling. Research suggests lysine supplementation may be particularly beneficial for individuals with iron-deficiency-related hair shedding, especially when combined with iron supplementation.
How It Works
Enhances intestinal iron and zinc absorption; serves as a building block for keratin protein synthesis; may modulate 5-alpha-reductase activity.
Evidence For Conditions
Side Effects
- Gastrointestinal discomfort (nausea, diarrhea)
- Abdominal cramps at high doses
- Potential kidney stress in individuals with renal impairment
Drug & Supplement Interactions
- Calcium supplements (lysine increases calcium absorption — may require monitoring)
- Aminoglycoside antibiotics (potential for increased nephrotoxicity)
- Iron supplements (synergistic — may enhance iron absorption)
