For optimal absorption, calcium citrate is highly recommended. It is easily absorbed by the body with or without food and is gentle on the stomach, making it an excellent choice for maintaining strong bones and muscles. To get the most benefit, pair your calcium with Vitamin D3, which is essential for helping your body absorb the mineral effectively. Another common option is calcium carbonate, though it must be taken with meals to absorb properly. Always consult your doctor to determine the right daily dosage for your specific health needs.
