Puori CP1 Pure Collagen Peptides (unflavored, 30 servings)

1. Ingredients 35% of the rating 5 of 5

   One ingredient, hydrolyzed collagen peptides, with nothing else on the label: no flavor, sweetener, gum or added amino acid.

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

   All 23 posted batch reports from an ISO 17025 lab pass metals (lead not detected in 22, 0.18 µg in one) and recent ones pass phthalates and PFAS, but Puori pays for the program.

3. Sourcing 10% of the rating 2 of 5

   “Grass-fed” is stated but no farm, country or certifier is named, and a 2022 survey said Puori did not claim it.

4. Trust 10% of the rating 3 of 5

   Puori publishes every batch and names the lab, but a 2026 lead notice names its CP2 collagen and whey blend as an example of protein powder, and a 2018 notice, settled, named two other powders.

5. Value 10% of the rating 2 of 5

   About $3.60 per 25 g of protein at the maker’s $39, among the dearest powders we list, though collagen is bought for its peptides.

The rating, 3.9 of 5, is the weighted average of these scores. See how we rank protein powders & shakes and our standard.

• Paid certification Ellipse Analytics, for Clean Label Project’s Transparency Project (Puori pays): all 23 CP1 batch reports on Puori’s results page August 2026

  Reports dated 18 August 2023 to 4 August 2026. Heavy metals pass in every one, against limits per serving of 10 (arsenic), 4.1 (cadmium), 0.3 (mercury) and 0.5 µg (lead): lead not detected in 22 and 0.179 µg in batch 8624035 (May 2024); cadmium and mercury never detected; arsenic not detected or 0.15 to 0.28 µg. Bisphenol A and glyphosate not detected throughout. No report says fail. PFAS is listed as Pass in 13 reports, with no analytes or figures. Some reports were posted with label-claim, phthalate, bisphenol S or antibiotic checks pending or not run. Open ↗ (opens in a new tab)

• Paid certification Ellipse Analytics, for Clean Label Project’s Transparency Project (Puori pays): batch 8626121 July 2026

  Certificate dated 15 July 2026 (expires 30 April 2028): arsenic, cadmium, mercury and lead not detected; phthalates BBP, DBP, DEHA and DEHP not detected (limits 1,200, 8.7, 2,200 and 310 µg); BPA and glyphosate not detected (BPS not run); pesticides, residual solvents and antibiotics pass; protein 10.63 g against 9 g claimed; PFAS listed as Pass, without figures.

• Paid certification Ellipse Analytics, for Clean Label Project’s Transparency Project (Puori pays): batch 8626003 March 2026

  Certificate dated 11 March 2026 (expires 30 August 2028): arsenic, cadmium, mercury and lead not detected per serving (limits 10, 4.1, 0.3 and 0.5 µg); BPA and glyphosate not detected; pesticides, residual solvents and antibiotics pass; protein 10.58 g against 9 g claimed. Phthalates, PFAS and BPS were not run in this one. Open ↗ (opens in a new tab)

• Paid certification Clean Label Project certificate DSP0007-2018B-01 (Puori pays) January 2025

  Issued 1 January 2025, lists “CP1 Pure Collagen Peptides” (UPC 815667021066, listed 25 February 2020) with the CLP Certified and Pesticide Free marks. The label also shows the Purity Award, which this certificate does not list for CP1. That UPC is the one on Amazon’s listing; the maker’s own store shows another barcode (815667031065), so the certificate may predate the current pack. CLP says brands choose to be certified and that it is supported partly by certification fees from brands. Open ↗ (opens in a new tab)

• Independent Mamavation, a consumer blog that earns affiliate commissions on collagen it recommends September 2022

  Its 2022 survey of collagen and gelatin brands lists Puori CP1 among those that “tested very clean” for lead, not claimed grass-fed at the time. It publishes no figures and names no lab for that result. Open ↗ (opens in a new tab)

Is there lead in Puori’s collagen?

Not in the 23 CP1 batch reports we read: lead was not detected in 22 and was 0.179 µg in one, against a limit of 0.5 µg a serving. But California’s Attorney General lists a May 2026 notice (opens in a new tab) alleging lead in protein powder that names Puori’s CP2 Active Collagen and Whey Protein Powder as a non-exclusive example, with no settlement posted, and a 2018 notice (opens in a new tab), since settled, on its Greens G3 and CB3 Pure Carbs powders (search (opens in a new tab)). Neither names CP1, but the 2026 notice’s examples are not exclusive.

Is the collagen really grass-fed?

Puori’s page (opens in a new tab) says yes and the label reads “grass-fed bovine”, with no farm, country or certifier. Mamavation’s 2022 survey said CP1 did not claim to be grass-fed, so the claim may be newer than that test.

Has anyone tested for phthalates or PFAS?

In some batches, yes, paid for by Puori. Ellipse’s reports for batches 8625180 (December 2025), 8626100 and 8626121 (July 2026) list phthalates as passed, with BBP, DBP, DEHA and DEHP not detected in the one we read in full, and 13 reports list PFAS as a pass with no analytes or figures. The other reports, including 8626003, show them as not run or leave them out. Mamavation’s own phthalate and PFAS tests of collagen covered a different brand, Perfect Supplements.

Does collagen work, and is it a protein I can rely on?

Our types and benefits article says collagen peptides likely improve skin elasticity and hydration, with some trial evidence for joint pain at about 10 g a day, and rates its confidence 3 out of 5. Collagen is not a complete protein, so it does not replace whey or food protein.

Do people who recommend it get paid?

Some may. Puori’s site footer lists an Affiliate Program, so a creator’s praise could be paid, and Mamavation’s 2022 write-up links CP1 through an Amazon affiliate short link, so the blog may earn a commission. We did not check whether any promoter owns part of the brand.

• The label is one ingredient: hydrolyzed collagen peptides (grass-fed bovine). Per 10 g scoop it has 9 g of protein, 35 calories, 50 mg of sodium and no sugar, flavor or sweetener.
• Puori posts a certificate of analysis for each batch, made by Ellipse Analytics, an ISO/IEC 17025 lab, for Clean Label Project’s Transparency Project. We read all 23 posted for CP1 (August 2023 to August 2026): every one passes heavy metals. Lead was not detected in 22 and was 0.179 µg in one (May 2024), cadmium and mercury were never detected, and arsenic was not detected or 0.15 to 0.28 µg, against limits of 0.5, 4.1, 0.3 and 10 µg a serving.
• The same reports pass bisphenols, glyphosate and pesticides. The newest full ones (8626100 and 8626121, July 2026) also list phthalates and PFAS as passes, and 8626121 shows its four phthalates not detected. Protein found was 9.3 to 10.8 g against 9 g on the label in the 20 reports that give it.
• Clean Label Project’s certificate lists CP1 by UPC, and a 2022 Mamavation survey put it among the collagens that “tested very clean”.

• Puori pays for the testing program, so the batch reports are a certification, not an independent test. The lab that tests also signs the certificate.
• Phthalates and PFAS were not run in every batch: 13 reports list PFAS as a pass, but only as a one-word summary with no analytes or figures, and the other 10 (including 8626003 from March 2026) show it as not run or leave it out. Some reports were posted with label-claim, solvent or antibiotic checks still pending.
• “Grass-fed” is Puori’s word: the page names no farm, country or certifier, and Mamavation wrote in 2022 that Puori did not claim grass-fed.
• California lists a 2026 lead notice on “protein powder” that names Puori’s CP2 collagen and whey blend as a non-exclusive example, and a 2018 notice, since settled, on its Greens G3 and CB3 Pure Carbs powders. Neither names CP1.
• $1.30 a serving at the maker, about $3.60 per 25 g of protein ($3.24 at Amazon’s $35), one of the dearest per gram of protein we list. Collagen is not a complete protein.
