This is a really important question, and the answer comes with a critical caution specific to myeloma. Before taking any calcium supplement, it's essential to have your calcium blood levels checked by your doctor first. Myeloma can actually cause hypercalcemia (high calcium levels), which affects more than 1 in 4 people with myeloma at some point — making supplements potentially unsafe without medical guidance. If your doctor confirms supplementation is appropriate, here are the key considerations:

- Calcium carbonate (e.g., Caltrate, Os-Cal) is generally preferred — take it with food for best absorption
- Calcium citrate is an alternative if you have lower stomach acid
- Take no more than 500 mg at one time to maximize absorption
- Add vitamin D to help with calcium absorption — but again, check with your doctor first, as too much vitamin D can cause its own side effects
- Avoid supplements derived from bone meal or dolomite due to potential lead contamination

If taking bisphosphonates like Zometa for bone lesions, calcium supplementation may be especially important to prevent levels dropping too low. Always run any supplement plan past your oncology team first, as supplements can interact with myeloma treatments.
