GREEN NUTRITIONALS Calcium Powder or Capsules

Calcium requirement and the actual take up of Calcium by the body is influenced by many factors. Government agencies are reviewing RDI (recommended daily intake) for Calcium and suggested intake levels are being raised. Children have a higher need to build bones and teeth, just as we need to keep making deposits into our 'Calcium Bank' as we get older.

Conditions that reduce calcium absorption include high or excessive intakes of oxalates and phytates, found in foods such as spinach and oats. Consumption of alcohol, coffee, sugar, or medications such as diuretics, tetracycline, aluminium containing antacids, hormonal imbalances and stress reduces absorption of calcium and other minerals.

Lack of exercise reduces calcium absorption as well as causes an increase in calcium loss. A lifestyle of immobility also leads to calcium deficiency. Calcium deficiency increases risk of bone disorders such as osteoporosis, and may increase the chances of obesity.

Factors that improve calcium absorption include adequate amounts of protein, magnesium, phosphorous, trace minerals and Vitamin D. Vitamin D is best obtained from regular exposure of the skin to moderate sun-light.

The table to the right is a guide to recommended intake, but bear in mind the factors mentioned above. Less than half of all Australian adults get their daily recommended intake of calcium.
