If you are familiar with B-12, you will understand my points here. This is a meaningful 1000 mcg dose in a very good tasting cherry flavored lozenge which will easily dissolve under the tongue (making it much more effective that being swallowed). The 1000 mcg translates to 41,867% DV, but don't let that mislead. B-12 is not stored, and most of it when taken orally is passed through (which is why therapeutic doses are administered by syringe). So summarizing . . . this is a good meaningful dosage, the only active ingredient is B-12, it will dissolve in the mouth to assist in absorption, and it's rather yummy tasting. Recommended.
