I have been using Folic Acid 5mg oral supplement EOD since starting b12 injections just over three weeks ago. I was getting some loose bowel, so was advised to try Methylfolate every day instead. However I am wondering if I should be using injectable Folic 5mg instead. My problem is malabsorption due to low stomach acid after using PPIs for too many years, probably plus a dose of entonox in 2019.
Any thoughts?
