Effects of Nitrous Oxide on B12 levels ?

Ryaan profile image

I would like to know what effect does Nitrous Oxide have on your B12 levels ?

My son (20 years old) had a colonoscopy and they gave him the gas that one time a couple of months back. What effect does the gas have with a one time use on a person who doesn’t have PA. Does your body naturally recover if it does lower your B12 levels without taking supplements ?

Hi Ryaan

Nitrous oxide is a super-oxidiser when it comes to B12 and converts it to a form that the body cannot use, so if you had an absorption problem and couldn't replace your the oxidised B12 with new B12 then it would be a permanent problem.

If your son does not have an absorption problem and eats animal products he should be able to replace the B12 naturally


I am not a medically trained person.

Like clivealive says, it will rapidly oxidise any B12 In encounters. That can almost totally inactivate all the B12 in your blood. Luckily, the liver stores quite a lot of B12. Some of it will soon replace the B12 that has been deactivated. Assuming you don’t have an absorption problem.
