Is taking 1500 mcg of B12 too much for your health?

The recommended daily intake of vitamin B12 for most adults is only 2.4 mcg, making a 1500 mcg supplement seem extraordinarily high. However, because B12 is a water-soluble vitamin, excess amounts are generally considered safe and simply excreted from the body. This high dose is often prescribed to effectively treat deficiencies, rather than being meant for routine, long-term maintenance.
