Vitamin B12 1000 mcg Price Guide: Per-Unit Math

Vitamin B12 is the most-stocked B vitamin in our tracking data — over 500 live offers across retailers at any given time — and it is also the clearest example of a category where the sticker price tells you almost nothing. Today, bottles with the identical label claim, 1,000 mcg of B12 per unit, run from $0.99 to $22.40 in this guide alone. That looks like a simple quality gap until you divide price by count: the real spread between the cheapest and most expensive per-unit offers is 7.2 times, and the ranking has almost nothing to do with the sticker price.

This guide shows you the one number that matters — price per unit, normalized to the same 1,000 mcg dose — so you can rank any bottle on the shelf in about ten seconds. Every deal below links to its current listing page, and every price was pulled from live retailer listings on October 14, 2026.

What you are actually buying

Every product in this guide is a single-ingredient vitamin B12 bottle — no B-complex blends, no added folic acid or iron — so the comparison stays apples to apples. Within that constraint, two label details explain most of the price variation:

1. The form of B12. Cyanocobalamin is the most common and usually the cheapest form on shelves. Methylcobalamin and hydroxocobalamin are different chemical forms that appear on more premium-priced bottles. The form is printed on the supplement facts panel; knowing which one a bottle contains is the first step to comparing it against the right peers.

1. The delivery format. Tablets, capsules, sublingual lozenges and nuggets, fast-dissolve tablets, and gummies all deliver B12. Format changes what you pay per unit: gummies and fast-dissolves carry flavoring systems, while plain tablets and capsules are usually the cheapest per unit. Sublingual formats sit in between, and their units (lozenges, nuggets) count exactly like capsules for the math below.

One more trap to rule out before comparing: check the serving size. Some gummy labels state the dose per serving of two or three gummies, not per gummy. If a bottle says 1,000 mcg per serving and the serving is two gummies, the per-unit cost of 1,000 mcg is double the naive price-per-gummy number. Count units, not servings, when you compare.

The only math that matters: price per unit

Per-bottle prices are designed to confuse comparison. A $0.99 bottle and a $22.40 bottle can each be the better deal — it depends entirely on how many units are inside and what you pay per 1,000 mcg.

The formula:

Price per unit of 1,000 mcg = total price ÷ unit count

This works across every B12 format because one tablet, capsule, lozenge, nugget, or gummy at the 1,000 mcg strength is one dose. Applied to today's live single-ingredient 1,000 mcg offers:

Read the per-unit column, not the price column. The $0.99 gummy bottle costs less than half as much per unit as the $7.13 fast-dissolve bottle, and the $22.40 name-brand two-pack lands second-cheapest per unit despite being the most expensive sticker in the table. The 7.2x spread between the top and bottom rows is the entire reason to do this division before you buy.

The label trap in this category: gummy serving sizes

The Piping Rock gummy bottle in the table above prints its dose as 1,000 mcg per serving, and its listing reads 60 gummies for $0.99. If that serving is one gummy, the per-unit math in the table holds exactly. If the label on the bottle says the serving is two gummies, the true cost per 1,000 mcg is about $0.033 — still the cheapest in the guide, but half again what the naive division suggests. This is why the first checklist item below is reading the serving line, and why gummy-label doses deserve one extra glance compared with tablets and capsules, where one unit is almost always one serving.

The same rule protects you in the other direction: a two-gummy serving bottle at a higher sticker price can quietly be a better per-dose deal than its per-gummy price suggests. Count units of 1,000 mcg, not containers, and the comparison takes care of itself.

The annual math: what a one-a-day habit costs

If you take one unit a day, a year is 365 units. Applied to today's table:

The Vitamatic 60-count fast-dissolve costs about 7 times as much per year as the Piping Rock gummies for the same labeled dose. Small bottles of convenience formats are the most expensive habit in this category; the pattern from the creatine and vitamin D3 guides repeats here — count is the whole game.

Where the name-brand sublingual fits

Solgar is the name-brand sublingual in this guide: a two-bottle pack of 250 nuggets each, 500 units total at $22.40 — about $0.045 per nugget, second-best in the table, and one purchase covers more than 16 months of one-a-day use. We track Amazon supplement listings alongside every other retailer; the Amazon supplement offers page lists everything currently tracked from that retailer across categories, and it is where multi-bottle pack positions like this one tend to appear first.

One caveat on marketplace pricing: Amazon listing prices move more often than specialty-retailer prices, sometimes daily. Verify the price on the listing page at checkout time — the figure quoted here was pulled on October 14, 2026.

How to spot a genuinely good vitamin B12 deal

Because B12 is a single-ingredient commodity, deal quality is objective. Work through this checklist before clicking buy:

1. Confirm the serving line before you divide. One unit per serving makes the math in this guide exact; a two- or three-unit serving doubles or triples the true per-dose cost. Gummies are where this bites most often.

1. Compute price per unit yourself. Price divided by count — ten seconds. Ignore the sticker price entirely.

1. Compare the same form when the per-unit prices are close. Cyanocobalamin, methylcobalamin, and hydroxocobalamin are different chemical forms with different typical prices; when two bottles cost the same per unit, the form line is the tiebreaker, read straight off the supplement facts panel.

1. Buy the count you will actually finish. The per-unit math favors big bottles, but units that sit past their expiration date are a worse deal than a mid-size bottle at a slightly higher rate. Match the count to your real usage.

1. Price single-ingredient B12 against single-ingredient B12. B-complex bottles and B12-plus-folic-acid blends are different products; mixing them into the comparison makes every number meaningless.

Where to track vitamin B12 prices over time

One-off deal pages go stale. If you buy B12 regularly, the smarter habit is a page that refreshes:

• The vitamin B12 ingredient page lists every B12 offer currently tracked on the site, filterable by format and retailer.

• The capsule supplement deals hub rounds up current capsule-format offers across ingredients.

• The site-wide deals page is the front door for everything tracked across all supplement categories.

The short version

Vitamin B12 at 1,000 mcg is a commodity: confirm the serving line, confirm the form on the facts panel, then buy the lowest price per unit in a count you will finish. Today that means the 60-count Piping Rock gummies at about a penny and a half per unit for value buyers, the 500-nugget Solgar sublingual two-pack at about four and a half cents for name-brand sublingual fans, and the 250-count Bronson lozenges at about five cents as the bulk sublingual alternative. Recheck the live table before you buy — prices on this page move with the market.
