Treatment and prevention of calcium deficiency (hypocalcemia); support for bone health in osteoporosis and osteopenia; management of rickets and osteomalacia; calcium supplementation during pregnancy and breastfeeding; support for proper muscle, nerve, and heart function.
Calcium Lactate provides elemental calcium in a highly bioavailable form. Calcium is an essential mineral vital for bone and tooth formation, muscle contraction, nerve signal transmission, and blood clotting. When taken orally, the calcium is absorbed in the intestines and distributed throughout the body to maintain normal calcium levels in blood and tissues.
Should be taken with food or as directed by a healthcare provider to enhance absorption. May interact with certain medications including tetracycline antibiotics, bisphosphonates, and thyroid medications—take these at least 2-4 hours apart. Adequate vitamin D is necessary for optimal calcium absorption. Patients with kidney disease, hypercalcemia, or certain heart conditions should consult their doctor before use. Side effects may include constipation, gas, or bloating.
