Quick answers
- Does lansoprazole interact with calcium or vitamin D tablets?
- No direct interaction, but long-term lansoprazole reduces stomach acid needed for calcium absorption, so vitamin D supports this — check with your pharmacist about timing and whether blood tests are needed.
- Can omeprazole cause vitamin deficiency?
- Yes, long-term omeprazole use can interfere with absorption of vitamin B12, magnesium, and calcium because it reduces stomach acid needed to absorb these nutrients, particularly after 12 months of continuous use.
- What vitamins should I take with omeprazole?
- Consider vitamin B12 (especially after a year of use), vitamin D to support calcium absorption, and possibly magnesium if blood tests show low levels — always discuss supplementation with your GP first.

1 · What do you take?
PPIs have no major food "avoids" — the real story is what years of acid suppression do to B12, magnesium, and iron absorption.
Take 30-60 minutes before breakfast for best effect. No foods are banned — but if you have been on a PPI long-term, it is worth asking about B12 and magnesium checks, and eating well for both.
