Is Nature Made vitamin C USP Verified?
Latest price check:
- Capsules, softgels and tablets: Nature Made Vitamin C Extra Strength 1000 mg (300 tablets).
- Gummies and chewables: Nature Made Chewable Vitamin C 500 mg (60 tablets).
Partly: 9 of the 16 Nature Made vitamin C packages we track, not all of them. USP's directory names a product and a strength, not a package, and USP says the mark on the label is how a buyer knows. So a package counts as USP Verified here only when both hold: the product is in USP's directory, which we read in full, and this package's own label prints the USP Verified Mark. Every row below marked yes or no was read against that directory, with the row it matches quoted; 2 rows are not settled either way yet, and are marked that way, not as absent.
USP's directory names a product and a strength, not a bottle size, so bottles that match the same row can get different answers here: each counts only if its own label prints the USP Verified Mark.

What the directory says
USP's Verified Products directory carries 7 rows matching products in this table, each quoted above beside the package it was read against. USP publishes no page for a single product and no listing ID, so the row itself is the record, and each product page names the day the directory was read.
3 products here had no row in USP's directory on the day it was read. A directory row is one of the two things this site needs before it calls a package USP Verified, and the card below says what each label prints. Absence from a directory is not a failed test.
2 products here match a directory row that is not yet confirmed for the package we price. The card below says why; until it is settled, the product page shows them as unconfirmed and none of them can be a pick.
2 products here are not settled either way yet. A directory row may cover them; until that is settled against this exact package, the product page shows them as unchecked and none of them can be a pick. The card below names the directory row and says what the label prints.
What each product page shows
Every Nature Made product we track, across all categories: Is Nature Made third party tested?
Where to buy: the vitamin C shortlist
The pick is the cheapest product that clears four bars:
- certified, and named at the exact package where the certifier names packages
- no adverse finding on record
- a price its retailer let us read recently
- no more than a year’s supply at the label’s serving
It is ranked per delivered dose where the retailer publishes a delivery rate. Where none does, it is the cheapest such product before delivery, and it says how far the order is from free delivery. It is the same pick the category page shows. Any other answer beside it is the cheapest under a different rule, and its own line names that rule. Answers that cost more than the pick are folded into one line until you open it.
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. Every package we price, with its delivery terms, is on the Vitamin C page.

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 the retailer publishes no delivery rate, the pick is priced before delivery and says so. Nothing we track here clears all of those yet. Each of these misses at least one bar, and says which:

Full comparison of every product in this category: Vitamin C. Every question we answer: the question index.
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.
