  • 98% of the 14,425 products that print an amount of vitamin B12 list more than its 1 mcg of vitamin B12 (median 36 mcg).

The NIH database records one serving a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.
