Which plant protein brands are third-party tested?

9 of the 21 plant protein products we track have their exact package named by a certifier. 2 more are certified by production batch instead, which names no package. Another 1 comes from a product line a certifier lists, but at a package size the certificate does not name. The remaining 9 appear in no database we searched.

A certifier lists a specific package against each certificate. A brand can sell the same formula in several sizes, or several flavors, and have one of them listed, so “this brand is NSF certified” can be true while the tub in your hand is not the tub NSF tested. The middle group below is that gap.

Each row names the plant source or sources its own panel prints. NSF lists some brands flavor by flavor, so one flavor of a line can be named while the flavor beside it is not; where a line comes in several flavors, one is priced and the row says which.

Certifier names this exact package, 9

The strongest evidence available here. For NSF, the listing names the package size sold; it was opened, its package text recorded, and its ID is on the product page. For USP, which names products rather than packages, the product is in USP's directory and the USP Verified Mark is on this package's own label, and both are on the product page.

Certified batch by batch, no package named, 2

Certified, but by production batch rather than by package: Informed Sport, Informed Choice and IFOS test and report lot by lot, so their listings name no tub, bottle or count. That is real independent testing of the product; it is not a statement that the package in your hand was the one tested.

Not listed by NSF Certified for Sport when we read its full directory. These programs certify what a company submits to them, so a product can be absent from the database simply because it was never entered, which is not a finding against it.

Where to buy: the plant protein 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 Thorne Plant Protein, Chocolate (676 g). 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 21 products and 21 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.

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.
