Vitamin C
Each format is ranked separately: each has its own pick and its own table, and none is priced against another.
Capsules, softgels and tablets
Our pick, delivery included · Cheapest independently tested, delivery known
Nature Made Vitamin C Extra Strength 1000 mg (300 tablets)$0.138per 1,000mg, delivered$4.14 a month
Cheapest per 1,000mg, delivery known
Sports Research Vitamin C 1,000 mg (240 veggie capsules)$0.127per 1,000mg, delivered$3.81 a month
Not our pick: no independent verification we could locate.
Least to spend today
Nature Made Vitamin C 500 mg (100 tablets)$0.32per 1,000mg, delivered$9.59 a month
More per 1,000mg, but $25.40 less to spend today, delivered.
How these lines are chosen
Among 29 products and 29 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of the size in the heading, priced the same way as the per-dose figure beside it. “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.
Why this pick, and what's cheaper
Not a score, no weightings to argue with. It is the cheapest per delivered dose among products clearing four factual bars (a certification we confirmed applies to this package, naming it where the certifier names packages; no recall, warning letter or failed test in the sources we checked; a price its retailer let us read within its cache limit; no more than a year's supply at the label's serving) and whose delivery cost we actually know. It is provisional: it is the best answer within the products, retailers and sources we have actually checked, and that universe is still narrow.
Powder
Cheapest per 1,000mg, delivery known
Thorne High Potency Vitamin C, Buffered (42 servings)$0.294per 1,000mg, delivered$8.81 a month
How these lines are chosen
Among 24 products and 24 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of the size in the heading, priced the same way as the per-dose figure beside it. “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.
Nothing here clears every bar, so there is no pick
A pick has to be independently certified, at the exact package sold where the certifier names packages, and carry no recall or failed test. Where a retailer does not publish a delivery rate, the pick is priced before delivery and says so. Nothing here clears that bar yet. These came closest, with what stopped each one:
Thorne High Potency Vitamin C, Buffered (42 servings) $0.294 per 1,000mg, no independent verification we could locate.
Nutricost Sodium Ascorbate Powder, Unflavored (454 g) $0.05 per 1,000mg, no independent verification we could locate; delivery cost is not published. Free delivery starts at $59.00, so this order is $39.03 short.
BulkSupplements.com Sodium Ascorbate (Buffered Vitamin C) Powder (500 g) $0.054 per 1,000mg, no independent verification we could locate; delivery cost is not published. Free delivery starts at $59.00, so this order is $35.03 short.
“Delivery cost is not published” usually means the retailer only publishes a free-delivery threshold and no rate below it. Adding anything else to the same order clears it. We cannot price that cart for you, so we show the gap instead of guessing.
Gummies and chewables
Our pick, delivery included · Cheapest per 1,000mg, delivery known · Cheapest independently tested, delivery known
Nature Made Chewable Vitamin C 500 mg (150 tablets)$0.403per 1,000mg, delivered$12.08 a month

Liposomal
Cheapest per 1,000mg, delivery known
Sports Research Vitamin C Liposomal (180 liquid veggie capsules)$0.708per 1,000mg, delivered$21.23 a month

Priced per 1,000 mg of vitamin C as each label prints it. That is a yardstick, not a suggested dose. Capsules and tablets, powders, gummies and liposomal products are each ranked on their own.
Prices checked daily. Every figure links to its source. Where the data comes from

Common questions
How much does vitamin C cost?
What 1,000 mg of vitamin C costs from each label, one format at a time: the lowest, middle and highest price in each, and how many packages. Before delivery.
What is the cheapest vitamin C?
Every vitamin C we price, ranked by what 1,000 mg costs as its label prints it and only against the same format, with which packages a certifier confirms.
Which vitamin C brands are third-party tested?
Every vitamin C we price, grouped by whether a certifier confirms the exact package sold, lists it without confirming it, or lists nothing we found.
Do third-party tested supplements cost more?
The cheapest product we track in each category beside the cheapest one a certifier names at the exact package, where one exists, and the gap per dose.
Is BulkSupplements third party tested?
Every BulkSupplements product we track, by whether a certifier names the exact package sold, only another size, or nothing we found. With listing IDs.
Do supplement travel packs cost more per dose?
Every travel pack or single-serve packet we price, next to the same brand’s smallest tub or bottle of the same product, per comparison dose.
Is Thorne third party tested?
Every Thorne product we price, checked in NSF’s Certified for Sport database: which listing names the exact package sold, with the listing IDs.

Which supplements are NSF Certified for Sport?
Every package we price that NSF names in its Certified for Sport database, by category, with the listing IDs and what each listing actually covers.
Do supplement prices actually change?
We re-read every price we can read automatically each day and keep every reading. Which prices have moved since we started, which have not, and by how much.
How many capsules is one serving?
How many pills the label calls one serving, across every capsule, tablet and softgel we price, and what that does to the count on the front of the bottle.

Every BUBS Naturals product we price, checked in NSF’s Certified for Sport database: which listing names the exact package sold, with the listing IDs.
Is Sports Research third party tested?

Is Nature Made third party tested?
Every Nature Made product we price, checked against USP’s Verified Products directory and its own label: which packages carry both, product by product.
About these numbers
What “per dose” means here: 1,000mg vitamin C
1,000 mg is a round figure inside the range of strengths vitamin C is sold in, chosen so packages of different strengths can be priced against each other. It is a yardstick for comparing prices, not a recommended intake, and it cannot change which product is cheapest: it scales every row by the same number. Packages are ranked one format at a time (capsules, softgels and tablets; powders; gummies and chewables; liposomal) and never across formats. Adopted on October 17, 2026, when the category was built.
Compared on the milligrams the Supplement Facts panel prints on its Vitamin C line, never on the weight of a compound. The form the panel names (ascorbic acid, sodium ascorbate, calcium ascorbate and others) is shown as a spec and is never a ranking input.

Where the data comes from
Every claim links to its source. Products, prices and certification listings are read from the retailers' own stores and the certifiers' own databases, and each figure links to the record it came from, so you can check any of them.
- Where a label does not state servings per container, the figure is derived from net weight and the product page says so.
- Amazon and Walmart are not included, so “cheapest” means cheapest among the retailers we track.
- Prices go stale. Each one shows when it was last checked, and says so when it is older than the retailer allows us to cache it.
- iHerb prices cannot be refreshed automatically. iHerb has not given us access to its price data, so those prices are marked stale until they are re-read. Each retailer offer carries its own check date.
Found something wrong? Tell us. Corrections are the point.
How we make money
No Buy button on this page earns us anything. The only links on the site that can are the Amazon links shown below the price comparison on some product pages, outside the comparison, and each says so beside it.
Commission will play no part in what we list, how it ranks, or which link we send you to. The Buy button points at the lowest price we have recorded even when that retailer pays us nothing.
