While B12 is naturally present in animal-based foods such as meat, fish, and dairy, many people struggle to get adequate amounts due to dietary restrictions, absorption issues, or certain medical conditions
Patients often take B12 shots to improve their mood and energy levels, since B12 supports the production of serotonin and dopamine and encourages the conversion of food to energy
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
