Calcium and L-Lysine are generally complementary — many people take them together. Lysine (500–1000 mg/day) can be taken concurrently with calcium to enhance absorption and retention. Particularly useful in individuals with low bone density or recurrent calcium kidney stones (where lysine reduces urinary calcium).
Combined lysine and calcium supplementation improves calcium retention and may reduce urinary calcium loss. Studies suggest lysine co-administration increases intestinal calcium absorption and reduces calcium excretion, potentially beneficial for osteoporosis prevention.
L-Lysine enhances intestinal calcium absorption by stimulating specific calcium transport in intestinal cells and reducing urinary calcium excretion by promoting renal tubular reabsorption. Lysine may form soluble calcium-lysinate complexes that improve bioavailability. Additionally, lysine is essential for collagen synthesis (hydroxylysine crosslinks), supporting the bone matrix upon which calcium is deposited.
What to do: Lysine (500–1000 mg/day) can be taken concurrently with calcium to enhance absorption and retention. Particularly useful in individuals with low bone density or recurrent calcium kidney stones (where lysine reduces urinary calcium).
