CalAsorb supplies calcium in the citrate form, which is believed to be one of the most easily absorbed compounds of calcium. Three tablets provide a full 800mg of calcium, the recommended daily allowance. This is particularly important for women, who should aim to have an intake of up to 1200mg of calcium per day. Many people's diets provide insufficient supplies of calcium, and yet calcium plays an important part in the maintenance of normal healthy bones. The recommended daily intake is three tablets.
