Can I take Omeprazole and Vitamin b12 together?

Why this happens

Vitamin B12 is naturally bound to proteins in food. To release the vitamin so your body can use it, you need stomach acid. Omeprazole works by reducing the amount of acid your stomach produces. With less acid available, the B12 stays 'locked' in the food and passes through your system without being fully absorbed.

What you should do

If you take omeprazole for more than 2 to 3 years, ask your doctor to check your vitamin B12 levels with a blood test. You should also watch for signs of low B12, such as feeling very tired, having a sore tongue, or feeling 'pins and needles'. If you need a supplement, high-dose oral tablets or B12 injections usually work well because they don't rely as much on stomach acid for absorption.
