How much B12 per day?
Approved answer
Daily Recommended Intake of Vitamin B-12
The advised daily intake of vitamin B-12 for adults is 2.4 micrograms. However, it has been noted that higher doses are generally safe to consume. Your body only absorbs the amount it requires, with any excess being excreted through urine. It’s also important to note that elevated doses of vitamin B-12, typically used to address deficiencies, can potentially lead to headaches.
