• Calcium Carbonate 500mg: primary bone-building mineral
• Vitamin D3 400 IU: essential cofactor for intestinal calcium absorption — without D3, less than 15% of dietary calcium is absorbed
• Magnesium (if combined): co-factor in bone mineralisation

• Calcium is the primary building block of bones and teeth — deficiency significantly increases fracture risk
• Vitamin D3 doubles calcium absorption in the body and must be present alongside calcium
• Women after menopause lose bone density rapidly and need extra support
• The elderly reduce outdoor activity, reducing sun exposure and therefore vitamin D synthesis

• For women over 40 as prevention against osteoporosis
• For the elderly experiencing joint or back pain
• After fractures or bone surgery to accelerate recovery
• For pregnant and breastfeeding women who need additional calcium

• If you have kidney stones or hypercalcaemia, consult your doctor before use
• Calcium may interact with certain antibiotics such as tetracycline — separate them by at least two hours
• Do not exceed the recommended daily dose

• One to two tablets daily as recommended by your doctor
• Best taken with food to improve absorption and minimise stomach discomfort
• Avoid taking it with tea or coffee as these can reduce calcium absorption

Q: Is calcium from food enough or do I need a supplement?

A: If you regularly eat dairy products and leafy vegetables you may only need a supplement occasionally. If you cannot consistently maintain a calcium-rich diet, a supplement ensures you meet your daily requirement.

Q: Can calcium tablets cause kidney stones?

A: Moderate doses are safe for healthy individuals. Those with a history of kidney stones should consult their doctor before starting any calcium supplement.

Q: How long should I take Cal D?

A: Cal D can be taken long-term as part of a daily routine, especially for women over 40. Your doctor will determine the appropriate duration based on your individual condition.
