All three of these correct a B12 deficiency. That is the honest starting point, and it means the choice comes down to money and form preference rather than results. Nature's Bounty is the cheapest per tablet at review-time prices. Webber Naturals has the lowest upfront bottle price, which matters if you are testing whether you will stick with it. Igennus is the one to buy if a practitioner specified methylated forms. What none of them will do is give energy to somebody whose levels are already normal, and this guide starts there because the marketing never does.

Frequently Asked Questions
Which B12 supplement should I buy in Canada?
For pure cost per dose, Nature's Bounty 2500mcg. For the cheapest first bottle, Webber Naturals 5000mcg at about $11. For methylated forms on a practitioner's advice, Igennus. All three correct deficiency effectively, so the decision is budget and form preference rather than outcome.
Is 5000mcg of B12 too much compared to 1000mcg?
Both work, because passive absorption captures only around 1% of an oral dose regardless of size. That is why 1000mcg and 5000mcg tablets both deliver corrective amounts. The bigger number wins label impressions rather than bloodwork, so choose on price and count.
Does B12 give you energy if you are not deficient?
No. Controlled research finds no stimulant or energy effect in people whose B12 levels are already normal. Correcting a genuine deficiency relieves the fatigue the deficiency caused, which feels like new energy, and the marketing sells that story to everybody else.
Cyanocobalamin or methylcobalamin: does the form matter?
For most people, less than the price difference suggests. Cyanocobalamin is stable and converts in the body, and comparative evidence shows both forms correct deficiency. Specific medical situations and personal philosophy can justify methylated forms, which is exactly what the Igennus product is for.
Who actually needs to take B12?
Four groups with solid evidence behind them: vegans and vegetarians, adults over 50, people on metformin or long-term acid reducers, and anyone with an absorption disorder. Outside those groups a varied omnivorous diet generally covers it, and a blood test settles the question before you spend anything.
