deficiency is a concern with the use of all drugs that reduce stomach acidity.
In food, vitamin B
is always accompanied by proteins, and it must be separated from them before it can begin to be absorbed. Following separation, B
is then attached to a substance called intrinsic factor, which allows B
to be absorbed in the intestines.
Stomach acid plays a role in this separation. If you don't have enough stomach acid, the process of freeing vitamin B
from protein so that it can be bound to intrinsic factor may be impaired.
Studies suggest that treatment with proton pump inhibitors might significantly reduce the absorption of vitamin B
Interestingly, there is some evidence that cranberry juice might increase B
absorption in individuals taking proton pump inhibitors,
possibly because the juice is somewhat acidic.
