Puori PW1 Grass-Fed Whey Protein (Unflavored)

1. Ingredients 35% of the rating 5 of 5

   One ingredient, whey protein concentrate, with nothing added: no sweetener, flavor, lecithin or gum.

2. Independent testing 35% of the rating 4 of 5

   Two unflavored batches read: lead, cadmium, arsenic and mercury not detected, by an accredited lab, but Puori pays for the program and CLP’s list does not show this pack.

3. Sourcing 10% of the rating 3 of 5

   New Zealand and pasture-raised are stated, but no farm, certifier or audit is named.

4. Trust 10% of the rating 4 of 5

   Puori publishes every batch and names the lab; one open 2026 Prop 65 lead notice about protein powder names its CP2 blend, not PW1.

5. Value 10% of the rating 2 of 5

   $2.74 for 25 g of protein, higher than every powder we reviewed except Momentous.

1. Whey protein concentrate (milk)

• Paid certification Ellipse Analytics, for Clean Label Project’s Transparency Project (Puori pays) September 28, 2026

  Batch 26240 of the unflavored powder: arsenic, cadmium, mercury and lead not detected per serving (limits 10, 4.1, 0.3 and 0.5 µg). BPA, BPS, glyphosate, phthalates, pesticides, residual solvents and antibiotics pass. Protein found: 23.29 g. Open ↗ (opens in a new tab)

• Paid certification Ellipse Analytics, for Clean Label Project’s Transparency Project (Puori pays) June 10, 2026

  Batch 26141 of the unflavored powder: the same four metals not detected, and the same other tests pass. Protein found: 23.36 g against 24 g claimed. Open ↗ (opens in a new tab)

• Paid certification Clean Label Project certificate DSP0007-2018B-01 January 2025

  Lists PW1 Bourbon Vanilla and Dark Chocolate with the Purity Award and Pesticide Free marks, which screen for heavy metals, pesticides, glyphosate, phthalates and bisphenols. It does not list the unflavored pack. Open ↗ (opens in a new tab)

• Independent Clean Label Project 2025 protein study (a nonprofit that also sells certifications) 2025

  Tested 165 protein powders. PW1 Bourbon Vanilla, a different flavor from this page, made its Clean Sixteen list, which CLP says was non-detect for lead, cadmium, mercury and arsenic. CLP does not publish per-product figures. Open ↗ (opens in a new tab)

Is the unflavored pack really Clean Label Project certified?

Its label shows the marks and Puori posts unflavored batch reports through the Transparency Project. But CLP’s certificate (opens in a new tab) and brand page (opens in a new tab) list only the vanilla and chocolate, so we could not confirm it.

Is there lead in Puori’s powders?

Not in the two unflavored batches we read. A May 2026 Prop 65 notice (opens in a new tab) alleges lead in protein powder and names Puori’s CP2 collagen and whey blend as its example, not PW1. It has no settlement posted, and a 2018 lead notice was resolved.

Is the whey really grass-fed and from New Zealand?

Puori says so on the product page (opens in a new tab) and names no farm or certifier. We could not check it.

Do the people recommending it get paid?

One organic-living blogger lists Puori with a 20% code and says purchases through her links support her work (opens in a new tab). We found no ownership or investor tie to any influencer.

Does it contain lactose?

Yes. The label says whey protein concentrate (milk and lactose). An isolate has less lactose.

• The label is one ingredient, whey protein concentrate, with 24 g of protein in a 30 g scoop. The Bourbon Vanilla we reviewed before has five, including coconut palm sugar and a stevia-derived flavor, so we switched this page to the unflavored powder.
• Puori posts a report for every batch, made by Ellipse Analytics (an ISO/IEC 17025 lab) for Clean Label Project’s Transparency Project. Both unflavored batches we opened, 26240 (September 2026) and 26141 (June 2026), found arsenic, cadmium, mercury and lead not detected, against limits of 10, 4.1, 0.3 and 0.5 µg a serving.
• The same reports pass bisphenols, glyphosate, phthalates, pesticides, residual solvents and antibiotics, and the protein found (about 23.3 g) matches the label.
• Clean Label Project’s own 2025 study of 165 protein powders put the Bourbon Vanilla in its Clean Sixteen, the products with the lowest contaminant levels.

• It is the second most expensive whey on our list: $79 for 30 servings, about $2.63 a serving or $2.74 for 25 g of protein.
• Puori pays for the testing program, so the batch reports are a paid certification, not an independent test. The lab and the certifier overlap: Ellipse Analytics both does the testing and signs Puori’s certificate.
• Clean Label Project’s published certificate (issued January 2025) lists the Bourbon Vanilla and Dark Chocolate, not the unflavored pack. The unflavored label carries the marks anyway, and its batch reports are on Puori’s site. We could not confirm the unflavored listing at Clean Label Project.
• “Grass-fed, pasture-raised” and “New Zealand” are Puori’s words. No farm, certifier or audit is named.
• It is a concentrate, so it carries some lactose. It is not on the NSF Certified for Sport, Informed Choice or Informed Sport lists, so we found no banned-substance testing.
