The benefits of vitamin B12 shots.
Whenever people find it difficult to maintain adequate vitamin B12 levels, either because they have an absorption problem or follow a vegan or vegetarian diet, B12 supplements often come to their aid. Unlike vitamin B12 tablets that have to go through our stomach before reaching the bloodstream, thus reducing significantly our body’s absorption rate, a vitamin B12 injection delivers the much-needed nutrient directly into our blood and with it the following benefits:
- balanced metabolism
- increased energy levels
- improved cognitive function
- better sleep
- improved bone density
- better mood
- weight loss
Furthermore, regular injections of vitamin B12 may reduce the risk of numerous medical conditions, such as:
- heart disease
- age-related macular degeneration
- vision loss
- neural tube defects
Vitamin B-12 injections are considered to be safe and come with no major adverse effects. The effects of a vitamin B12 shot usually last between 48 and 72 hours after the injection, but since each body is different, the duration may vary. Depending on the patient’s vitamin B-12 deficiency, the doctor may prescribe between five to seven injections in the first week of the treatment.
