Overview
Nature's Bounty Vitamin B12 is a quick dissolve 5000mcg tablet sold in a two pack of 40 tablet bottles, positioned for energy metabolism and nervous system support.
Quick dissolve tablets are meant to be taken without water, dissolving under the tongue or in the mouth, which is the usual format for high dose B12 since the vitamin doesn't need swallowing and digesting to take effect. No flavor, form details or allergen information came through in this listing beyond the tablet count and dose.

Who it's for
Works for anyone wanting a no water B12 tablet rather than a capsule or liquid, and the two bottle pack suits people who don't want to reorder every few weeks.
