A lack of vitamin B12 doesnt directly lead to weight gain, however, so getting a B12 injection alone wont cause you to lose weight no matter how many times your doctor calls the injection a skinny shot
Improvements in hair thickness, texture, and growth rate typically become more apparent at the four-to-six month mark and continue to improve over the following months
In terms of weight loss, if you have a vitamin B12 deficiency, which is likely, you will lose some of the vitamin B12 shot in the first 48 hours, but at least 50% of it will be stored in your liver
But theres a lesser-known, clinically-backed supplement thats been quietly making waves in wellness and medical communities alike: Vitamin B12 injections
This is especially common in individuals working in industries where they are regularly exposed to these substances
