Vitamin B12 is either injected under the skin or into muscle tissue
This case underscores that regulatory bodies consider it professional misconduct to experiment on patients with dubious therapies
Adequate B12 levels protect against nerve damage, numbness, and tingling that can become irreversible if left untreated
Products are not intended for personal, therapeutic, or clinical use

Contraindications include known hypersensitivity to any component of the injection (including cobalt hypersensitivity), a history of severe reactions to thiamine/pyridoxine/cobalamin injections, and Lebers hereditary optic neuropathy (for B12-containing products)
