My mother is 80 years old and very low on Vitamin D, she has stomach and intestinal issues which make taking supplement by mouth not an option, she doesn't get in the sunlight. Her doctor says he has never heard of shots for this and doesn't know how/where to get medication/vitamins for shots. I find that very strange that a doctor wouldn't know this however he has requested I find out how so I am hoping someone can provide some information so I can point the doctor in the right direction to treat my mother. Thank you
