What Our Research Found
Premium B12 rests on one question: do the bioactive forms beat cheap cyanocobalamin? Igennus answers by putting methyl, adenosyl and hydroxo in the same tablet, keeping the excipient list short, and shipping 180 servings. We looked at what that trio buys and what the evidence says it doesn't.
For correcting deficiency in most people, form differences are small, because cyanocobalamin converts to the active forms inside the body. The multi-form case rests on covering conversion edge cases and on buyer preference. It does not rest on demonstrated superiority for the average user, and nobody selling it should pretend otherwise.
Execution here is the premium tier done properly. 1000mcg sublingual dosing is fully corrective given roughly 1% passive absorption. The three forms mirror the body's own active and storage variants. The excipient list is short, and 180 servings mean one bottle covers half a year. The 4.7-star aggregate suggests owners get what the label promises. What the trio really buys is coverage of rare conversion inefficiencies, the theoretical case where cyanocobalamin's conversion step underperforms, and Igennus charges for that hedge up front.
Bottom line
Do the arithmetic before judging the price tag. The bottle runs about $29.99 for 180 servings. Webber's cheapest entry is $10.78 for 60 tablets, and Nature's Bounty sits at $19.08 for 120. Per tablet, Nature's Bounty is the cheapest of the three, Igennus lands in the middle, and Webber's megadose is actually the priciest per unit. So the premium here is a checkout premium, not a daily one. If methylated forms aren't a requirement, the smaller bottles still win on entry cost with identical bloodwork outcomes.
It earns its place with deliberate premium buyers. Anyone correcting routine low B12 should read our Webber Naturals review and start with the cheaper bottle.
Do bioactive B12 forms outperform cyanocobalamin?
The body runs on two active B12 coenzymes. Methylcobalamin handles methylation reactions, adenosylcobalamin handles mitochondrial metabolism, and absorbed B12 of any supplemental form gets converted into them as needed. Hydroxocobalamin, the trio's third member, is the long-retention form favoured in clinical injections. The multi-form pitch says supplying all three bypasses the conversion step. The counterpoint is that conversion works fine in the vast majority of people, which is exactly why basic cyanocobalamin corrects deficiency reliably in studies and in practice.
The Good & The Bad
thumb_up What We Loved
- check
All three bioactive forms in one tablet
Methyl, adenosyl and hydroxo cover the body's active and storage variants. No other mainstream bottle assembles the set this completely.
- check
Genuinely clean label
The excipient list is short. That backs the premium positioning with something you can read rather than something you have to believe.
- check
180 servings change the arithmetic
Six months per bottle brings the per-serving cost down into commodity range. The premium is real at the till and close to invisible per day.
- check
The right pick when a practitioner said methylated
It executes that instruction more completely than the single-form methyl bottles it competes with.
thumb_down Honest Drawbacks
- close
The $30 bottle is a real barrier at checkout
Basic corrective B12 starts around $11, so this asks roughly triple that to walk out the door. Head-to-head data showing the premium forms outperform in typical users is thin, which means the extra money buys theory.
- close
Lower per-tablet dose than the megadose labels
1000mcg corrects deficiency, but anyone comparing labels sees 5000mcg on cheaper bottles and has to be talked out of the obvious conclusion.
- close
It won't energize a body that isn't deficient
No B12 form does. Premium chemistry doesn't move the category's honest ceiling by a millimetre.
- close
Less familiar brand on Canadian shelves
Igennus is a UK name with lighter distribution here than Webber or Nature's Bounty. Availability and pricing move around more than they do for the drugstore staples.

How It Works
Sublingual tablet, corrective dose, three forms. The routine holds no surprises.
Confirm the need
The same evidence-backed groups apply here as to every B12: plant-based diets, adults over 50, metformin and acid-reducer users, absorption disorders. Bloodwork first.
Dissolve under the tongue
1000mcg per tablet. Sublingual delivery is pleasant and pill-free, and at this dose passive absorption does the reliable work regardless.
Run the 180-serving supply
Half a year of daily use per bottle. That count is what turns a $30 sticker into pennies a day.
Retest and reassess
If your levels normalize exactly the way a basic tablet normalized them before, you have your answer about the premium.

Frequently Asked Questions
Is the Igennus B12 Complex worth the higher bottle price?
If your practitioner asked for methylated B12, or you've decided you won't take cyanocobalamin, then yes. For plain deficiency correction the cheap tablets reach the same bloodwork result, and they cost a third as much to walk out of the store with. Run the per-serving numbers before you assume this one is expensive, though.
What does taking three B12 forms together actually get you?
Methylcobalamin and adenosylcobalamin are the two coenzymes your body actually uses, and hydroxocobalamin is the long-retention form clinicians inject. Supplying all three skips the conversion step instead of trusting it. In most people conversion works fine, so treat the trio as insurance against edge cases rather than a daily upgrade.
Is methylcobalamin better than cyanocobalamin for deficiency?
Not meaningfully, for typical users. Both correct deficiency reliably, and the body turns cyanocobalamin into the active forms without complaint. Methylated versions make sense inside specific protocols and for buyers who object to the cyanide-derived molecule on principle. What you should expect from the swap is peace of mind, not better numbers on a blood panel.
Is 1000mcg of B12 enough to fix a deficiency?
1000mcg is plenty. Passive absorption captures roughly 1% of an oral dose, so a single tablet still delivers several times the daily requirement, and it sits inside the range used in oral correction protocols. The 5000mcg labels elsewhere buy a bigger number on the bottle rather than a better outcome.
Who should choose a methylated B12 over a cheap B12 tablet?
Three buyers, mainly. Someone whose practitioner specified methylated forms. Someone who reads excipient lists and wants the short one. Someone hedging against rare conversion trouble. Everyone else correcting ordinary low B12 gets more value from the basic corrective tablet.
What's the biggest drawback of the Igennus B12 Complex?
You're paying about $30 up front for benefits most people's blood tests will never detect. The 180-count softens that considerably, since the per-serving cost lands close to the commodity tablets. Still, the premium-form idea itself rests on modest evidence, and ordinary B12 remains this product's real competitor.
