What form of calcium
supplementation do you like the best? Both calcium citrate / malate and
calcium microcrystalline hydroxyapatite seem good. Do you prefer one over
the other? Do you know of any side effects or drug interactions with
either of these?
Thank you for your advice.

Laura:
Both citrate malate and hydroxyapatite are good forms. For Osteoporosis
and fractures I use them together. As for drug interactions, the most
common ones are:
- Calcium - may reduce the effectiveness of
Ca+ channel blockers.
- Glucocorticoids - may lower serum Ca+
Oral Contraceptives - may improve absorption of Ca+.
- Tetracycline - use when long term may
deplete Ca+.
- Calcium decreases bioavailability of
ciprofloxacin.
- Digoxin increases renal Ca+ clearance.
- Neomycin impairs Ca+ absorption.
- Phenobarbital (long term) reduces Ca+
absorption.
- There are other drugs that can effect Ca+, as well. Check.
