If you suspect you have experienced side effects from a prescribed B12 medicine, you can report this through the MHRA Yellow Card scheme
Lipotropes in lipotropic injections include a mix of different vitamins, minerals, and amino acids that some people report help them lose weight and fat

Commenters noted the measure's complexity and reporting requirements create a regulatory burden for which hospitals must divert resources in order to come into compliance
