The recommended daily intake of vitamin B12 for most adults is about 2.4 micrograms. However, vitamin B12 is water-soluble, and excess amounts are typically excreted rather than stored in the body, making it relatively safe even at higher doses. Some supplements provide much larger doses, often ranging from 500 to 5,000 micrograms, which are generally considered safe but should be taken under medical advice, especially for those with certain health conditions. Always consult a healthcare professional before starting any new supplement regimen.
