Upper intake level
Adults, 2,000mg a day, from food, beverages and supplements together. One serving of this product holds 400mg, less than that level on its own. This level is for vitamin C only; the panel also prints food blend 575 mg (organic orange, organic brown rice, organic cranberry, organic blueberry, organic broccoli head, organic parsley leaf, carrot, organic beetroot), which it does not cover.
An upper intake level is the largest daily intake unlikely to cause harm for most people. It is not a recommendation about what to take.

In whole units
3 tablets = 1,200mg for $1.27
This is the smallest whole number of tablets that holds at least one comparison dose. It is shown as a caveat and is deliberately not used in ranking, because rounding up changes the amount as well as the price.
- One comparison dose is 2.50 tablets, and tablets cannot be split. The smallest whole number that holds at least the 1,000 mg comparison dose is 3 tablets, which hold 1,200 mg.
- Printed on the panel image this product page publishes for both sizes as "Vitamin C (as ascorbic acid) 400 mg 444%" in a "Serving size 1 tablet" serving. Milligrams of vitamin C are the comparison basis and the panel prints milligrams, so nothing is converted. The panel prints no servings-per-container line; this bottle's own front prints "90 TABLETS | 90 SERVINGS", the label's own count on the panel's serving. The 90-tablet bottle is the "90 Day | 90ct" variant (SKU 10439) of the same product in the brand's own feed, and it carries the same one panel the page publishes for the line. The panel's second line is "Food Blend 575 mg" (organic orange, organic brown rice, organic cranberry, organic blueberry, organic broccoli head, organic parsley leaf, carrot, organic beetroot). It is named on this package's row as a second active; the price per dose pays for the 400 mg of vitamin C alone, and the marking changes no ranking. The label's VEGAN and GLUTEN FREE seals are what those two answers rest on; its Non-GMO Project Verified, kosher and "MADE WITHOUT 9 FOOD ALLERGENS" seals make no testing claim.
Delivery
Delivery cost
Applies, amount not published
Delivery is NOT free on this order. It is $12.01 below the $50.00 threshold, and this retailer does not publish a rate, so we cannot tell you what it will add. Free shipping on orders over $50 within the US, from MegaFood's own shipping policy page, first read September 1, 2026: "Q: How much does shipping cost? A: All orders over $50 ship free", with a site-wide banner saying the same. The page read the same on September 28, 2026. No rate is published for orders below $50, so delivered cost under the threshold is Unknown.
Cost per dose delivered
at least $1.06
We will not put a number on this. The product price is a floor, not the price you will pay. Reaching the free-delivery threshold, or choosing a retailer that publishes its rate, is the only way to know in advance.

Verification, Tier D: Could not locate independent data
We could not locate independent testing or certification for this product. That is a statement about our search, not about the product. These programs certify what a company submits to them, so a product can be absent simply because it was never entered, which is not a finding against it. Which certifier databases we searched, and when, is listed below. Where a program is not listed there, we have not checked it and do not imply anything either way.
- Searched 4 certifier databases and found no listing for this product, and located no published test results. Programs we did not search are named below as not checked.
- Checked NSF Certified for Sport database on Oct 17, 2026: not listed.
- Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked and absent. The Certified for Sport directory as captured on Sep 23, 2026 holds one MegaFood row, 1730628, its Micronized Creatine Monohydrate Unflavored Powder, and no vitamin C row. The label on this package prints no NSF mark. 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.

This brand does not appear in the directory or in its brand facet, and no product in it names this brand. USP verifies the products a company submits to it, so this records which products were submitted and nothing else. Absence from a database is not a failed test.
