Performance notes

This is an unflavored sublingual liquid dosed at 5,000 mcg, sold as a two-bottle, 4 fl oz pack with a kosher label. The liquid format requires measuring drops rather than taking a pre-portioned tablet, which is a meaningful difference from most of the rest of this category.

What buyers say

A 4.8 star rating is the highest among the products reviewed in this range, though its base of 369 reviews is smaller than the tens of thousands seen on some bestselling B12 tablets, so the sample is more limited even as the average score stands out.
