The active form of B12 — for the gap your medication quietly digs.
Acid reducers and metformin quietly lower B12 over years — that's why this is in your formula.
Under the tongue, any time of day — it skips the gut problem entirely.
If that prescription ever ends, the B12 usually follows it out.
“When a daily medication is quietly draining B12, replacing it is about as close to a sure thing as nutrition gets. When nothing is draining it and your level is fine, extra B12 does nothing — so it only appears in formulas that need it.”
Want the depth? It's all here — tap what you're curious about. Nothing below changes the three things above.
B12 keeps two systems running: red blood cell production and the insulation on your nerves. Absorbing it from food is surprisingly elaborate — stomach acid, intrinsic factor, an ileum that cooperates — and common medications interrupt the chain: metformin and acid reducers (PPIs) both drain B12 quietly over years.
Methylcobalamin is the form your cells actually use — no conversion step, and as a lozenge it absorbs through the mouth, bypassing the gut machinery entirely.
If your draw and your medication list don't ask for it, it's not in your formula. That's the whole idea.
How we weigh a study: we read it for you — including who paid for it. A study funded by the company selling the result is flagged and never load-bearing on its own. No supplement brand pays Liana — nobody's thumb is on this scale.
High relative to the RDA on purpose: passive absorption is about 1% — the dose is built around the leak.
Under-the-tongue absorption doesn't care about stomach acid — the exact pathway your PPI blocks.
When B12 is genuinely short, homocysteine runs high; both should move on the retest.
If the depleting medication ever leaves your regimen, B12 usually follows it out within a season or two of stable retests. While the medication stays, a small maintenance dose stays with it — this is one of the honest exceptions to 'the goal is zero,' and your report says so.
In an unregulated aisle, the brand is half the decision — so we made it for you.
Methylcobalamin, not the cheaper cyanocobalamin most gummies use — active as-is.
Dissolves in the mouth, so a PPI or metformin can't intercept it.
A long record in third-party consumer-lab testing for content accuracy — in a category famous for missing it.
Scored dosing fits a 500 mcg or 1,000 mcg formula from one bottle.
Your own formula names the right bottle for your case. No brand pays to be here.
