Is NOW Foods protein third-party tested?
Last reviewed 2026-10-11. Every certificate entry below was read in the programme's own directory on the date printed beside it, and each links its source. Product label figures come from the product data, read 2026-08-30.
Not that we can verify. NOW Sports Whey Protein Isolate has no entry in NSF Certified for Sport, Informed Choice or Clean Label Project.

NSF Certified for Sport: no entry found
Checked 2026-10-11: no entry for this brand in the NSF Certified for Sport directory (searched by brand; the brand filter named 323 brands on the check date). That is a statement about what the programme publishes, not a finding about the product.
Informed Choice: no entry found
Checked 2026-10-11: no entry for this brand in the Informed Choice directory (searched by brand; the brand filter named 202 brands on the check date). That is a statement about what the programme publishes, not a finding about the product.
Clean Label Project: no entry found
Checked 2026-10-11: no entry for this brand in the Clean Label Project directory (read the certified-brand index, which named 154 brands on the check date). That is a statement about what the programme publishes, not a finding about the product.
Informed Sport, a different programme from Informed Choice, showed NOW Foods as a certified brand when this site read it on 2026-08-29. A brand entry does not name this tub, and the per-product search was behind a bot challenge, so no product match exists.
