Overview
Nature Provides B12 Liquid Methylcobalamin Adenosylcobalamin 3000mcg 50ml sits on our vitamin b12 shelf, where the ranking comes from what buyers actually said rather than from what the box says. From the seller's own listing: Each 1 ml daily dose (13 drops) delivers 3000 mcg of both Methylcobalamin and Adenosylcobalamin, the 2 active forms your body can utilise immediately without conversion. Hold 13 drops (1 ml) under the tongue for 30 seconds to allow direct uptake into the bloodstream, bypassing digestive processing; the formula is almost tasteless with no aftertaste. That is the maker talking, not us, so read it as a claim rather than a finding. It holds 4.5 out of 5 on Amazon from 3,000 ratings. Where that leaves it next to the rest of the shelf is set out below.

How it compares on the vitamin b12 shelf
We track 52 rated vitamin b12 products, and the middle of that pack scores 4.6 out of 5. This one is on 4.5. Bottom quarter of the shelf. Not a red flag by itself, but similar money buys a better-rated option here, so the case for this one has to come from somewhere else.
3,000 people rated it, where the shelf median is 764. Enough reviews to trust the direction, not enough to close the question.
The shelf runs from £3.49 to £29.99 and the midpoint is about £9.99. On price, this one is in the top third. Paying above the middle of the shelf needs a reason the star rating does not supply, because on ratings alone the extra money is not buying an advantage here.

Key features, as the manufacturer lists them
Taken from the product listing via Amazon's product API. These are the seller's claims, not our test results.
Dual Bioactive B12 Formula: Each 1 ml daily dose (13 drops) delivers 3000 mcg of both Methylcobalamin and Adenosylcobalamin, the 2 active forms your body can utilise immediately without conversion; unlike single-form or cyanocobalamin products, this dual-form combination provides complete bioactive coverage; particularly suitable for those with MTHFR gene variations who may have difficulty converting standard B12 forms
