What Our Research Found
B12 occupies a strange spot in the supplement aisle. It's genuinely essential, genuinely deficient in millions of people, and marketed as an energy shot to everyone else. Webber Naturals sells Canada's default cheap megadose at roughly $11, so we set out to map who it actually serves.
Start with the number that makes sense of the whole category: passive B12 absorption runs around 1% of an oral dose. A 5000mcg tablet exists so that tiny fraction still clears your daily requirement several times over. The big number on the label is a delivery workaround, not a power level.
The tablet dissolves in your mouth, which sounds like a meaningful upgrade and mostly isn't. Swallowing works comparably for most people. What matters more is that at 5000mcg, even absorption-impaired users typically take in enough passively. That's why oral megadoses became a legitimate alternative to B12 injections for many deficient patients under medical supervision. Sixty tablets at this price puts the cost of starting a correction at the category floor, and a 4.7-star rating across a large Canadian buyer base suggests the tablets do what the bottle says.
Bottom line
If you're in a deficiency-risk group, this is an inexpensive, evidence-aligned correction tool. Confirm with bloodwork and let your doctor set the schedule. If you're not in one of those groups, expect to feel exactly nothing.
This belongs in the vegan pantry and the over-50 medicine cabinet. It does not belong in a morning routine bought on the promise of alertness.
Why does a B12 tablet need 5000 micrograms?
B12 deficiency concentrates in defined groups: plant-based eaters, since B12 is essentially absent from plants; adults over 50, whose declining stomach acid impairs the release of food-bound B12; and users of metformin or acid-suppressing drugs. Passive diffusion absorbs only around 1% of an oral dose, which is exactly why high-dose oral B12 works. One percent of 5000mcg still far exceeds daily requirements, and clinical practice increasingly accepts oral megadoses as an alternative to injections for many patients.
The Good & The Bad
thumb_up What We Loved
- check
Cheapest bottle in the category
Around $11 to start a correction is the lowest entry cost among the mainstream B12s, and the most micrograms per dollar by a wide margin.
- check
A dose backed by real protocols
High-dose oral B12 is an evidence-supported alternative to injections for many deficient patients, and this is the right strength for that job.
- check
Trusted Canadian brand
The 4.7-star aggregate across a large buyer base reflects consistent quality and tablets people don't mind taking.
- check
The one supplement vegans can't skip
B12 is essentially absent from plants. This covers a year of it for the price of a lunch.
thumb_down Honest Drawbacks
- close
No energy boost without a deficiency
The 'supports energy' framing only holds when you're correcting low B12. In a topped-up body, the surplus leaves in your urine.
- close
Cyanocobalamin only
Purists want methylated forms. The practical difference is likely small, but this bottle won't satisfy anyone who has decided otherwise.
- close
Quick-dissolve is mostly marketing
Sublingual delivery's absorption edge over swallowing is thin in the evidence. Buy the format because it's pleasant, not because it's superior.
- close
Megadosing forever without testing
Test, correct, retest is the sensible cycle. Taking 5000mcg indefinitely because a label suggested it is not.
- close
Small bottle for a long protocol
Sixty tablets runs out in two months of daily use, so committed daily users reorder more often than they would with a 120-count bottle.

How It Works
One tablet. The substance is in the dosing logic, not the ritual.
Confirm you need it
B12 status is a blood test away. The risk groups: vegans, adults 50+, metformin and acid-reducer users, and anyone with an absorption disorder.
Dissolve or swallow
Let the tablet melt under the tongue or swallow it. At this dose, passive absorption does the heavy lifting either way.
Dose on your doctor's schedule
Daily and every-few-days schedules both appear in deficiency protocols. Frequency is a medical call, especially when replacing injections.
Retest instead of guessing
Follow-up bloodwork tells you the correction worked. Subjective energy levels do not.

Frequently Asked Questions
Is 5000mcg of B12 too much to take every day?
For most people it's considered safe. B12 is water-soluble with no established toxic upper limit, and megadoses exist precisely because passive absorption captures only about 1% of the dose. Taking it daily forever without bloodwork, though, accomplishes nothing measurable. Test first, then let a doctor set the frequency.
Can B12 tablets replace B12 injections?
Often, yes. High-dose oral B12 in the 1000 to 5000mcg range achieves correction comparable to injections for many deficient patients, and clinical practice increasingly offers it first. Severe deficiency, neurological symptoms, or absorption diseases like pernicious anemia stay doctor-managed, where injections may still be the better route.
Does B12 actually give you energy?
If you were deficient, correcting that deficiency relieves the fatigue it caused, and it feels like new energy. In people with normal levels, controlled research finds no stimulant effect at all. The marketing borrows the deficiency story and sells it to everyone, which is where most disappointed reviews come from.
Cyanocobalamin vs methylcobalamin: does the form matter?
Less than the marketing implies. Cyanocobalamin is stable, cheap, and converts in the body, and comparative evidence shows both forms correct deficiency effectively. Specific medical situations and personal preference can justify methylated forms, at a real price premium this bottle sidesteps.
Who actually needs a B12 supplement?
Four groups with solid evidence behind them: vegans and vegetarians, adults over 50, users of metformin or long-term acid reducers, and people with absorption disorders. Outside those groups, a varied omnivorous diet typically covers B12 without any help from a bottle.
Is Webber Naturals B12 worth buying over pricier brands?
For deficiency correction, yes. It's the cheapest quality bottle to start with in Canada, and the vitamin behaves the same once it's inside you regardless of what the label cost. Buyers who specifically want methylated forms are the one group with a real reason to spend more.

Recurring themes we found across public owner reviews.
Deficient and vegan buyers dominate the positive reviews, with recurring reports of corrected bloodwork at follow-up and appreciation for a tablet that dissolves pleasantly.
The scattered disappointments come from buyers who expected a felt energy lift and noticed nothing, which is the predictable outcome in people who weren't deficient.
Price loyalty runs strong. Many owners describe switching from pricier brands after comparing labels and finding the same vitamin for a fraction of the cost.
