Frequently Asked Questions (FAQs)

1. Does calcium protect your immune system?

“We found that calcium signals play a vital role in keeping the immune system finely balanced, ramping responses up and down at the appropriate time,” says senior author Stefan Feske, MD, an associate professor of pathology at NYU Langone.

2. What vitamin helps with calcium absorption and the immune system?

Vitamin D is involved in calcium absorption, immune function, and protecting bone, muscle, and heart health. It occurs naturally in food and your body can also produce it when your skin is exposed to sunlight.

On the other hand, recent studies have linked calcium supplements with an increased risk of colon polyps (small growths in the large intestine that can become cancerous) and kidney stones, which are hard masses usually formed in the kidneys from an accumulation of calcium and other substances.

4. What is the best type of calcium to take as a supplement?

Calcium carbonate supplements tends to be the best value, because they contain the highest amount of elemental calcium (about 40% by weight). Because calcium carbonate requires stomach acid for absorption, it's best to take this product with food.
