Vitamin C
Each format is ranked separately, with its own table and, where one qualifies, its own pick; 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, and its price was last read Nov 4, 2026 and we cannot refresh it automatically.
Last known price, Nov 4, 2026; we have no automatic way to refresh Sports Research (direct)'s prices.
Least to spend today
Nature Made Vitamin C 500 mg (100 tablets)$0.32per 1,000mg, delivered$9.59 for thirty doses of 1,000mg
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 1,000mg, priced the same way as the figure beside it. It is worked out before that figure is rounded, so it can differ from thirty times it by a few cents. It is not thirty servings where a serving holds more or less than 1,000mg. “Delivery known” ranks only products whose retailer publishes a delivery rate. A cheaper product whose rate is not published is in the full list below.
Why this pick
Not a score, no weightings to argue with. It is the cheapest per delivered dose among products whose delivery cost we know and that clear 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 current price, not a last known one
- no more than a year's supply at the label's serving
It is provisional. It is the best answer among the products, retailers and sources we have checked, and that set 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 for thirty doses of 1,000mg
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 1,000mg, priced the same way as the figure beside it. It is worked out before that figure is rounded, so it can differ from thirty times it by a few cents. It is not thirty servings where a serving holds more or less than 1,000mg. “Delivery known” ranks only products whose retailer publishes a delivery rate. A cheaper product whose rate is not published is in the full list below.
Nothing here clears every bar, so there is no pick
A pick has to clear four bars:
- independently certified, and named at the exact package where the certifier names packages
- no recall or failed test
- a price its retailer let us read recently
- no more than a year’s supply at the label’s serving
Where a retailer does not publish a delivery rate, the pick is priced before delivery and says so. These came closest, with what stopped each one:
Nutricost Sodium Ascorbate Powder, Unflavored (454 g) $0.05 per 1,000mg, before delivery, no independent verification we could locate. Free delivery starts at $59.01, so this order is $39.04 short.
BulkSupplements.com Sodium Ascorbate (Buffered Vitamin C) Powder (500 g) $0.054 per 1,000mg, before delivery, no independent verification we could locate. Free delivery starts at $59.01, so this order is $35.04 short.
Nutricost Vitamin C Powder, Unflavored (227 g) $0.062 per 1,000mg, before delivery, no independent verification we could locate. Free delivery starts at $59.01, so this order is $45.04 short.
Gummies and chewables

Nature Made Chewable Vitamin C 500 mg (60 tablets)$0.626per 1,000mg, delivered$18.79 for thirty doses of 1,000mg
Cheapest per 1,000mg, delivery known
Nature Made Vitamin C Extra Strength Dosage 1000 mg Chewables (90 tablets)$0.531per 1,000mg, delivered$15.93 a month
Not our pick: whether a certifier's listing covers it is not settled.

How these lines are chosen
Among 12 products and 12 retailer listings we track; Amazon and Walmart are not included. A month is thirty doses of 1,000mg, priced the same way as the figure beside it.

Where a retailer does not publish a delivery rate, the pick is priced before delivery and says so. These came closest, with what stopped each one:
Nutricost Liposomal Vitamin C 1,500 mg (120 capsules) $0.244 per 1,000mg, before delivery, no independent verification we could locate. Free delivery starts at $59.01, so this order is $37.04 short.

Core Med Science Liposomal Vitamin C (180 capsules) $0.444 per 1,000mg, before delivery, no independent verification we could locate. Free delivery starts at $75.00, so this order is $35.01 short.
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 are checked daily where a store can be read automatically; Nordic Naturals and Sports Research are read by hand, less often, and a price past its date says so. 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?
Per category, we compare the cheapest product we track with the cheapest a certifier names at the exact package: one format, and one strength where it matters.
Is BulkSupplements third party tested?
Every BulkSupplements product we track, grouped by what we found: a listing at the exact package, at another size or form, one not yet settled, or none. 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.
Is Core Med Science third party tested?
Every Core Med Science product we price, checked in NSF’s Certified for Sport database: which listing names the exact package sold, and the IDs.
Which supplements are NSF Certified for Sport?
Every package we track that NSF names in its Certified for Sport database, by supplement and brand, with the listing IDs and what each listing actually covers.
How do you check that a supplement is NSF Certified for Sport?
Where to search, why the search results are not enough, and which line of the listing to read against the package in your hand. No prices and no store links.
How do you work out what a supplement costs per dose?
Type the price, servings and amount per serving of one package or two. It works out each one's cost per serving and per comparison dose, and which costs less.
Do supplement prices actually change?
We keep every price reading we take: daily where a store can be read automatically, less often where it is read by hand. 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 have a price for, and what that does to the count on the front of the bottle.
Is MegaFood third party tested?
Every MegaFood product we price, checked in the NSF, USP and Informed databases: which listing names the exact package sold, and which we found no listing for.
Is BUBS Naturals third party tested?
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?
Every Sports Research product we track, checked in the certifier databases: which program lists each one, and which no database we searched lists.
Is Nature Made third party tested?
Every Nature Made product we price, checked against USP’s Verified Products directory, NSF’s Certified for Sport database and its own label, product by product.
Is Nature Made vitamin C USP Verified?
Nature Made vitamin C, every strength and form we price, checked against USP’s Verified directory and the USP Verified Mark on each bottle’s label.
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 servings-per-container figure was not read from the package's own panel, the product page says how it was worked out.
- Amazon and Walmart are not included, so “cheapest” means cheapest among the retailers we track.
- Prices go stale. Each product page shows when its price was last checked, and a price older than the retailer allows us to cache is marked as a last known price wherever it appears.
- 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. Where a link elsewhere on the site can, it says so beside the link.
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.
