What is the cheapest NSF Certified for Sport creatine?

Our pick: Optimum Nutrition Micronized Creatine Powder, Unflavored (1.2 kg), $0.25 per 5g delivered. NSF Certified for Sport does not list this package; it qualifies because Informed Choice lists it.
Buy at Optimum Nutrition (direct)why this one

BulkSupplements.com Creatine Monohydrate (Micronized) Powder (1000 g) is the cheapest per 5g, at $0.15 before delivery, at $29.97 a container.

17 of the 61 creatine 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. 10 more creatine packages, from Optimum Nutrition, NOW Foods and Sports Research, are certified by Informed Choice or Informed Sport, whose listings record tested batches and no package size at all, so they cannot be ranked by the exact-package test this page applies. Every brand, by program: Which creatine brands are third-party tested?

Named at the exact package, but not priced per 5g

Listed, but at another package

NSF lists these products, and the listing names a package other than the one we price. Very likely the same formula; not a package NSF has put its name to.

Cheapest among the 17 certified creatine packages we have checked, not the cheapest that exists. NSF certifies creatine 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.

Every brand in this category, by program: Which creatine brands are third-party tested? How much does creatine cost per serving? Is a bigger tub of creatine cheaper per serving? NSF Certified for Sport vs Informed Sport: what is the difference?

Where to buy: the creatine monohydrate 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.

Corrected Oct 2, 2026: until then the pick here was Sports Research Creatine Monohydrate, Unflavored (1 kg). Our record of Optimum Nutrition's own store left out the flat delivery rate its delivery page publishes below its free-delivery threshold, so delivery there counted as unknown and none of its packages could be the pick. With the rate recorded, its delivered cost is known.

How these lines are chosen

Among 61 products and 74 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.
