Our Verdict
The cleanest non-NSF option. Perfect Supplements doesn't have Sport-level certification, but it's Glyphosate Residue Free certified (rare in the category), passes PFAS testing, and Mamavation's heavy metal testing came back so clean that no Prop 65 warning is required. For people who care more about contamination than NSF batch testing, it's a strong alternative.
