Is Nature Made vitamin C USP Verified?
Our picks, each format ranked separately: Capsules and tablets: Nature Made Vitamin C Extra Strength 1000 mg (300 tablets); gummies and chewables: Nature Made Chewable Vitamin C 500 mg (150 tablets). Where to buy
Partly: 9 of the 16 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 certified product, at the exact package sold where the certifier names packages, with no adverse finding on record, a price its retailer let us read recently, and no more than a year’s supply at the label’s serving; 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 answer shown beside it is the cheapest under a different rule and says so on its own line; answers that cost more than the pick fold under one line until you ask for them.
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.

A pick has to be independently certified, at the exact package sold where the certifier names packages, and carry no recall or failed test. Nothing we track here is yet. Each of these misses at least one bar, and says which:

What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
