Administration of calcium and vitamin D3, counteracts the increase of parathyroid hormone (PTH). which is caused by calcium deficiency and which causes increased bone resorption. The source for Vitamin K2 is MK-7. MK-7's chemical structure enables Vitamin K2 to be bound to other fat particles in circulation such as LDL and set free in the bloodstream.

Combination of Vitamin K2 and Vitamin D3 with calcium promotes bone health and helps to optimize Calcium in the body. Dosage : Take 1 tablet daily with meal or as directed by the healthcare professional.
