Not recommended for patients with known hypersensitivity to Vitamin B12 derivatives
However, if you experience any serious side effects or worsening of any of the symptoms, please consult your doctor
B12 increases energy and metabolic rate while supporting weight loss, but it's most effective when combined with proper diet, exercise, and stress management rather than used as a standalone solution
The good news is that once you have done it a few times, it is very easy to do from that point forward
Non-medical usage, such as for immune boost, athletic preparation, or recovery, allows for personal choice in determining injection frequency, with some doctors suggesting a few vitamin B12 injections throughout the year
