In this blog, Timothy Beck, MD, of Life Point Medical, LLC, in Clayton, Georgia, explains what these injections do and how they may be able to help you
B12 is water-soluble, meaning your body excretes what it doesn't need rather than storing it to potentially harmful levels
Authors: Holly D
The honest framing: for many people with low intake, adequate oral or sublingual B12 restores levels well, while injections remain the route a GP chooses when absorption is the problem, for example after certain gut surgery or with pernicious anaemia
By dosage, the mean changes were: 500 mcg: 127% 750 mcg: 176% (single study) 1,000 mcg: 280% 1,500 mcg: 310% 2000 mcg: 260% 5,000 mcg: 62% While 1,500 mcg of vitamin B12 showed the highest average increase, the effect plateaued or declined at higher doses, suggesting a possible saturation of absorption pathways
A proper blood test gives your doctor the concrete data they need to make an accurate diagnosis and get you on the right treatment path
