Overview
A sublingual liquid combining methyl B12 with folate and folinic acid, dosed by dropper rather than swallowed as a pill. Why Not Natural markets it as organic and vegan, aimed at energy, brain, digestive and heart support.
Sublingual drops absorb under the tongue, which is the appeal for people who find B12 tablets slow to dissolve or hard to swallow. Pairing B12 with folate and folinic acid follows the common practice of dosing the two together, since they work through related metabolic pathways.
- 2 fluid ounce sublingual drops
- Methyl B12 plus folate and folinic acid
- Vegan, gluten free, keto
- Unflavored formula
Who it's for
Works for people who prefer liquid supplements over pills, or who want a methylated B12 and folate combination. Not the pick for someone who wants a plain, single-nutrient B12 tablet.
Strengths and trade-offs
Drawn from this product's published specifications.
- Sublingual liquid, no capsule to swallow
- Combines methyl B12 with folate and folinic acid
- Vegan and plant based
- Unflavored, easy to dose into any liquid
- Dropper dosing is less precise than a fixed capsule
- Liquid format needs more careful storage than capsules
Performance notes
Sublingual delivery lets the B12 and folate absorb through the tissue under the tongue rather than passing through digestion first, which is the reasoning behind the drop format. The 2 fluid ounce bottle is dosed drop by drop, so intake is adjustable rather than fixed per capsule.
