Your doctor might want you to get vitamin B12 injections, but oral B12, even for those who cant absorb it well, has long been considered one of medicines best kept secrets
Your doctor may include B12 infections as part of the treatment for conditions that are associated with poor nutrition, malabsorption of vitamin B12 from the intestines or deficiency of this vitamin due to obesity, vegetarian diets, or macrobiotic diets
If a deficiency does not exist, supplementing Vitamin B12 will likely not have the same positive effect. B12 injections are available, for $15 to $50 a pop, at spas and wellness centers, but its smart to talk to your physician before you spend money on them
Dosing information comes from published clinical trials and peer-reviewed literature as the primary source
