B12 pills may take 1 to 3 weeks to show results
Oral supplements (tablets or lozenges): Oral B12 must pass through the stomach and requires a protein called intrinsic factor to be absorbed
Designed for easy, one-handed use, it has a low dead space design specifically tailored for 1 mL/cc syringes, optimizing medication administration
As we age, our stomachs produce less hydrochloric acid or stomach acid, which is needed to absorb B12
To make these side effects less, doctors might change how they give the shot or where they give it
