Mechanism of action
Calcium Vitamin D3 1000 mg / 880 IU chewable tablets is a fixed combination of calcium and vitamin D3. The high calcium and vitamin D3 concentration in each dose unit enables sufficient absorption of calcium with a limited number of doses. Vitamin D3 is involved in calcium-phosphorus metabolism. It allows the active absorption of calcium and phosphorus from the intestine and their uptake by bone. Supplementation with calcium and vitamin D3 corrects latent vitamin D deficiency and secondary hyperparathyroidism.

The clinical relevance of calcium and vitamin D supplementation
NICE advises in TA1601 and TA1612 that supplementation should be considered for women who require bisphosphonate therapy unless clinicians are confident that patients are already calcium and vitamin D replete. Vitamin D levels decline with age and this is particularly apparent amongst frail elderly patients >75 years of age. NICE concludes that a dose of at least 1G of calcium and 800 units of vitamin D per day is reasonable for these patient groups.
theiCal-D3® 1000 mg / 880 IU chewable tablet is the first product designed to provide the lowest effective dose of calcium 1000mg per day combined with a dose of vitamin D in excess of the 800 IU recommended in combination to maintain bone health.
