Can I take vitamin B12 supplements with double-dose PPIs for reflux? Worried about the Vit B12 deficiency that might be caused with long-term PPI use.

Can I take vitamin B12 supplements with double-dose PPIs for reflux? Worried about the Vit B12 deficiency that might be caused with long-term PPI use.
