where should i inject my b12 shot to Vitamin injection sites for b12 shots

Presented for research literature review only Zupko SP et al

notes that a significant number of people who are B12 deficient are unable to absorb the vitamin from food or supplements, and so need to inject it, which they can only do at their GP practice

This review study highlights the biological effects of different NAD+ boosters as well as the unique benefits of direct NAD+ administration over oral precursors because it bypasses gut and liver metabolism

This allows for greater bioavailability and absorption, particularly in individuals who have difficulty absorbing it from their diet.

Thats not what they are for

Summary: Vitamin B12 pills do not cause weight loss in people with normal B12 levels, and no UK clinical guidance including NICE or NHS recommendations supports their use as a weight management intervention
