The panel prints "Vitamin C (as Ascorbic Acid & Sodium Ascorbate) 1000 mg 1111%" per serving of 4 gummies. We compare milligrams of vitamin C, and this label prints milligrams, so we used its 1000 mg as printed, with no conversion. The label names the form as ascorbic acid and sodium ascorbate. The calorie, carbohydrate, sugar and sodium lines the panel also prints are nutrition facts rather than a second active, and nothing is priced on them. The panel's own "Servings Per Container 20" against a serving of 4 gummies is 80 gummies, the count the front face prints.
Delivery
Delivery cost
$8.00
Below free delivery (orders of $25.00 or more); $5.51 more would make delivery free.
Set the quantity at the retailer. This calculator does not add items to a cart. Uses the recorded unit price with no coupon or quantity discount. Tax is extra. Delivery terms apply to the contiguous US unless the policy says otherwise.
Free shipping within the contiguous United States on orders of $25 or more before tax, and a flat $8 fee below that, from Nature Made’s own shipping policy page read September 23, 2026 and again on October 17, 2026: "Free shipping within the contiguous U.S. is available on: Orders $25+ (before tax)" and "A flat $8 shipping fee applies to: Orders under $25". Shipments outside the contiguous United States, including Alaska and Hawaii, carry the same $8 fee. The page calls neither term temporary. It also says some products or state requirements may add cost, shown at checkout, so a delivered total can be higher than these two figures describe.
Where to buy
Nature Made (direct) · lowest recorded available price
Ordered by price, lowest first, and labeled so you can see what each link earns us. Commission is never an input to that ordering. If the retailer with the lowest current price pays us nothing, that is still the one we send you to. No link on this page earns us anything. Every Buy button is a plain retailer link.
Price history
Latest recorded price: $19.49 at Nature Made (direct), checked . Unchanged since we started checking on Oct 17 (29 checks).
We check each price about once a day, so this is the range we recorded, not necessarily every price there has been. It says what changed, not why, and nothing about where the price goes next.
Verification level C: Claimed, not confirmed
Two different things reach this level, and the product page says which. Either the label or the product page names an independent third-party program, such as NSF Certified for Sport, NSF Contents Certified or Informed Sport, and we have not confirmed a listing for this package in that program’s own database; or the only test results available are ones the manufacturer or a lab it commissioned published, which may well be accurate and is simply not independent. A mark printed on a package is not the same thing as a listing anyone can open, and that gap is what this level records. It is not a finding against the product.
Testing claim we recorded, and where it appeared: USP Verified mark printed on the front label, and the back panel prints "USP has tested and verified ingredients, potency and manufacturing process. USP sets official standards for dietary supplements. www.uspverified.org". USP Verified is a program whose directory names products and strengths and publishes no page for a single product; whether that directory names this product is recorded in the USP row on this page. The certifier's directory holds an entry (Nature Made Vitamin C Extra Strength 500 Mg Gummies) that may cover this package; whether it does is not settled either way.
Checked NSF Certified for Sport database on Oct 17, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked and absent. The full Certified for Sport directory read of Sep 24, 2026 holds one row under Nature Made, listing 1809934 "Micronized Powder Creatine Monohydrate", and no vitamin C row under this brand at all. Absence from a database is not a failed test. NSF's whole directory was read again on Oct 17, 2026, 2,581 listings, and still holds no vitamin C listing under this brand.
USP's directory read of Sep 21, 2026 holds two vitamin C gummy rows from this brand, "Nature Made Vitamin C Extra Strength 500 Mg Gummies" and "Nature Made Zero Sugar Vitamin C Gummies 250 Mg Per Serving". This package's label prints the USP Verified Mark, and it is sold under a different name and serving, "Maximum Strength Dosage" with 1000 mg per serving of 4 gummies, under its own store handle; the Extra Strength gummies print 500 mg per serving of 2. USP's directory names a product and a strength, and this package's name and its strength per serving are not the row's, so whether the Extra Strength row covers this package cannot be read from the directory. It is left Unknown until it can be settled, with that row recorded as the entry that may cover it.
The program's directory holds an entry (Nature Made Vitamin C Extra Strength 500 Mg Gummies) that may cover this package. Whether it names this package is not settled either way, so this row is neither a listing nor an absence.
Nature Made is not on the October 2026 Informed Sport product list, which we read on Oct 3, 2026. The list, published by LGC, has 497 brands and 1,887 product lines. Not being listed is not a failed test. Informed Sport certifies what a company submits, so this means only that no product from this brand was on the published list that day.
Nature Made is on LGC's Informed Choice product list of October 2026, which we read on Oct 3, 2026. None of its 12 product lines names a vitamin C product. Not being listed is not a failed test. Informed Choice certifies what a company submits, so this means only that this product was not on the published list that day.
No laboratory report with figures is recorded here for this product.
Not established: Heavy-metal testing, Label-accuracy testing, Vegan status.
Absence of data is not evidence that a product is clean. It means we found no published result for that testing.

Vitamin C: 1,000mg as labeled
The panel prints "Vitamin C (as Ascorbic Acid & Sodium Ascorbate) 1000 mg 1111%" per serving of 4 gummies. We compare milligrams of vitamin C, and this label prints milligrams, so we used its 1000 mg as printed, with no conversion. The label names the form as ascorbic acid and sodium ascorbate. The calorie, carbohydrate, sugar and sodium lines the panel also prints are nutrition facts rather than a second active, and nothing is priced on them. The panel's own "Servings Per Container 20" against a serving of 4 gummies is 80 gummies, the count the front face prints.
Packages in the same category and format, with the same ingredients. Where we recorded the ingredient forms from the label, only packages with the same forms are shown. Where a category is compared by strength, they also have the same labeled strength. Only current prices are shown, cheapest container first. Prices are before delivery. Formulas, flavors and allergens may differ: check each label. These are browsing options, not recommended substitutes.
What this rests on: Prices are the last ones we recorded at the retailer named on each product page. Prices go stale, so each page says when it was checked. We track some products, not every one sold, and Amazon and Walmart are not among our stores. Listings and labels are read at the source, and each page links to them. Found an error? Tell us.
