For individuals with mild deficiencies or as a maintenance option after injections, oral B12 supplements or sublingual B12 formulations may be suitable alternatives

Vitamin B12 levels are higher, generally 50500 mcg, in supplements containing vitamin B12 with other B-complex vitamins and even higher, typically 5001,000 mcg, in supplements containing only vitamin B12

Most are not FDA-approved for human use, some exist only through a prescription or compounding pharmacy tied to a different condition, and the rest are sold exclusively as unregulated "research chemicals" not intended for human consumption

Although most people obtain enough B12 from their diet, some may need supplements due to health issues such as poor nutrition, stomach or intestinal problems, cancer, HIV, veganism, alcoholism, pregnancy, or old age
