Alendronate is a prescription medication. This page describes publicly documented interactions — it can't see your dose, your other prescriptions, or your labs. Discuss any supplement with the prescriber or pharmacist who manages this medication before combining.

Take alendronate first thing in the morning on an empty stomach, and zinc at least 2 hours later to avoid absorption issues.
- Calcium, iron, magnesium, zinc, antacids, and multivitamins bind oral bisphosphonate bone medications (such as alendronate, risedronate, and ibandronate) in the gut and can largely block absorption of a medication that is only minimally absorbed to begin with. Prescribing information has these medications swallowed first thing in the morning with plain water, at least 30-60 minutes before anything else — the calcium many people are advised to use for bone health fits later in the day. Follow the prescriber's or pharmacist's spacing directions rather than combining doses.
