General Safety: Vitamin B12 is known for its safety and is essential for various bodily functions, including red blood cell formation and nerve function
Supplementation with B12 may be advised for these groups, and it can be administered orally, through fortified foods, or by injection in cases where absorption may be impaired
It plays a significant role in protecting the lining of the gastrointestinal tract from damage, promoting healing, and encouraging blood vessel growth
This can occur due to conditions such as pernicious anemia, gastrointestinal disorders like Crohns disease, or following gastrointestinal surgery
The most consistent problem was the near-total absence of human clinical trial data for the proposed injectable routes
People may not be able to take vitamin B12 shots if they have a history of sensitivity to vitamin B12
