Calcium supplements from Pharma Nord contain calcium, vitamin D3, K1 and K2. Bio-Calcium + D3 + K1 + K2 uses a high percentage of elemental calcium in an easily absorbed form. Calcium and vitamin D contribute to the maintenance of normal bone in adults and the growth of bone in children. Older adults, in particular women around menopause, should have a daily intake of calcium to counteract the loss of bone mass which occurs in later life. Whilst young people need to build up strong bones at an early age.

Vitamin K helps support normal bone as well as contributing to normal blood clotting. Vitamin D also contributes to normal absorption of calcium and helps support normal blood calcium concentrations.
