The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other home health monitors: bathroom scales, blood pressure monitors, pregnancy and ovulation tests, thermometers, body composition monitors, stethoscopes, glucose monitors and pulse oximeters we track in this category on price, popularity and size.

Overview
This one comes as a berry-flavored liquid, sold in a 1 fl oz bottle with vitamin D also included alongside the B12, and is labeled gluten free. At around $34, it sits toward the higher end of the price range covered here, reflecting its liquid drop format rather than a bulk tablet count.
It carries a 4.8-star average across roughly 1,300 reviews, with about 700 units bought in the past month. That's a strong rating on a moderate review base, suggesting people who buy it tend to be satisfied with the format and flavor.
The maker markets the drops for metabolism support, and the sublingual liquid delivery is the main differentiator from the capsules and tablets that make up most of this category. Anyone managing a health condition or taking medication should talk to a healthcare professional before adding a new supplement like this to their routine.

Frequently asked questions
How is this different from a B12 tablet or capsule?
It's a liquid you take as drops under the tongue rather than swallow, sold in a 1 fl oz bottle. Some people find drops easier to dose or prefer avoiding pills altogether.
Does it contain anything besides B12?
Yes, the label lists vitamin D alongside the B12 in this formula, so it isn't a single-ingredient B12 product.
Is this something I should ask my doctor about first?
