What is the cheapest NSF certified collagen?
BulkSupplements.com Collagen Peptides Powder (Bovine), Unflavored (500 g) is the cheapest per 10g, at $0.565 before delivery ($27.97 a container).
8 of the 45 collagen peptides products we track have their exact package named in NSF's Certified for Sport database. That is a stricter test than “the brand is NSF certified”, and it is deliberately so: NSF lists package sizes against each certificate, and a size it does not name is not one it has stood behind. Each price is delivered where the retailer publishes a delivery rate and before delivery where it does not, and each row says which. 6 more collagen peptides packages, from Sports Research, are certified by Informed Choice, whose listings name no package size, so they are not in the tables below, which rank only packages NSF names. A pick can still be one of them, because the pick uses the category's own bar. Every brand, by program: Which collagen brands are third-party tested?

Cheapest among the 8 collagen peptides packages we track that NSF names at the exact package, not the cheapest that exists. NSF certifies collagen peptides from more brands than we carry, and our catalog is extended brand by brand, so a certified product we have not added yet cannot appear here however cheap it is.

Where to buy: the collagen peptides 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 44 products and 44 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 “Delivery known” ranks only products whose retailer publishes a delivery rate; a cheaper product with an unpublished rate is on its own line, or in the full list below.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, with no recall or failed test, a price its retailer let us read recently, and 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. This one 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.
