The short version
- One ingredient: 20 g of collagen peptides from bovine sources per 4-tablespoon serving (70 calories, 0 g sugar, 110 mg sodium) and nothing else listed [2].
- It holds a seal we could check: NSF’s public Certified for Sport directory lists the unflavored powder, including the 265 g (9.33 oz) canister [3]. That speaks to contaminants, banned substances and label accuracy, not to whether it works.
- The research is mixed rather than empty. Pooled skin trials lean positive, but most are rated high risk of bias, and one analysis found no effect in trials without pharmaceutical funding [4][5][6]. Joint findings are inconsistent and come mostly from adults with a diagnosed joint condition [7][8].
- A serving is 20 g, above the 1–10 g a day reported in two reviews of skin trials [9]. Amazon showed $18.65 for 9.33 oz on Sep 25, 2026 (about $1.33–$1.43 a serving) and lists it as non-returnable unless damaged or defective [12].
The four checks
Actives
DisclosedOne ingredient, collagen peptides (from bovine), with the amount stated (20 g) rather than hidden in a blend [2]. Not disclosed: the peptide supplier, or how finely it is broken down.
Testing
VerifiedNSF’s own directory lists this unflavored powder under Certified for Sport, including the 265 g and 547 g sizes [3]. We did not see the mark on the pack images we opened. See what testing seals mean.

What is inside
These figures come from the brand’s own supplement-facts image for the 9.33 oz canister [2]. It says about 14 servings; Amazon says 13 [12], and 265 g divided by 20 g is 13.25. New to labels? See how to read a supplement facts panel.
| Ingredient | Amount per serving | What to know |
|---|---|---|
| Collagen peptides (from bovine) | 20 g | Single ingredient. The brand describes it as enzyme-treated (hydrolyzed) collagen from grass-fed, pasture-raised bovine hide, types I and III [1][14]. |
| Protein | 18 g | Shown with a 0% Daily Value. The pack front says collagen is not a complete protein and should not replace dietary protein [1][2]. |
| Calories | 70 | For the 4-tablespoon (20 g) serving. |
| Total sugars | 0 g | The brand also states no artificial sweeteners, colors or flavors [1]. |
| Sodium | 110 mg | 5% of the Daily Value per the panel; worth noting if you count sodium. |
| Other ingredients | None listed | 9.33 oz label: made in a facility that processes milk and fish. The 19.3 oz label adds tree nuts [2]. |
The label says “Manufactured for: Vital Proteins” (Franklin Park, Illinois) and does not name the factory [2]. “Grass fed” and “upcycled bovine hide” are the seller’s own descriptions; we saw no outside certification for them.
What the testing seal covers
NSF’s directory lists “Collagen Peptides” from Vital Proteins LLC: unflavored powder, 20 g (4 tbsp) serving, package sizes from 140 g to 680 g including 265 g and 547 g, lot number “All” [3]. NSF says its Certified for Sport mark means the product contains none of 290 substances banned by major athletic organizations, the contents match the label, there are no unsafe levels of contaminants, and it is made at a GMP-certified facility that NSF audits [3]. It is a separate NSF program from NSF’s “Contents Certified” dietary-supplement listing, which on the same date also had a “Collagen Peptides” powder entry with a 20 g (4 tbsp) serving under the company name “Nestlé Healthcare Nutrition, Inc. DBA Vital Proteins” [3]; that entry gives no flavor or pack sizes, so we treat the Certified for Sport listing as the precise match. Nor is it the brand’s FAQ line that its “manufacturing facility is NSF certified cGMP” [14], which describes a factory rather than this product (NSF’s GMP-registration list does name that company’s Franklin Park, Illinois, site [3]). The product page shows only a bare “NSF” badge [1], and we did not see the mark on the pack images we opened, so check your own canister against the directory.
The seal does not tell you whether the collagen does anything for skin or joints. A fitness-review site also reports rating the unflavored powder in the top 10% of 150-plus protein powders in its own lab tests for label accuracy and purity [15]; it earns commissions and does not say how many lots were tested, so read that as an extra data point, not a certification.
What the research says
Skin
Most trials look at skin. A 2023 meta-analysis of 26 randomized trials (1,721 people) found better skin hydration and elasticity than placebo, while noting several biases in the trials it pooled [4]. A 2026 systematic review of 25 trials was more guarded: hydration improved in 10 of the 15 trials that measured it and elasticity in 10 of 13, but most trials were rated high risk of bias, and its authors call the clinical evidence inconsistent and the benefit preliminary [6].
The sharpest caution is a 2025 meta-analysis of 23 trials (1,474 people). Pooled, collagen looked helpful. Split by funding source, trials without pharmaceutical-company funding found no effect on hydration, elasticity or wrinkles, and high-quality trials showed no significant effect either; the authors concluded there is currently no clinical evidence to support collagen supplements for skin aging [5]. Industry groups dispute this, arguing that funding alone does not make a trial unreliable and citing what they call data errors [11]. Our read: positive studies exist, independent confirmation is thin, and the outcomes are instrument readings (skin water content, stretchiness) that do not tell you what you would see in a mirror.
Joints
Joint trials mostly enrolled adults with a diagnosed knee-joint condition, so they say little about healthy adults. A 2019 meta-analysis found lower total scores on a standard joint-symptom questionnaire and on a pain scale with collagen, but no significant change in that questionnaire’s pain or function sub-scores, though its stiffness sub-score fell [7]. A 2025 update pooling 11 knee trials (870 people) reported improvement in both function and pain, with large differences between trials (heterogeneity of 75% and 88%) [8]. That is a real finding in one specific group, with products and doses varying between studies. It is not evidence about this product or about people without that condition, and we did not assess who funded those trials.
How a serving compares with the doses studied
Reviews that report doses put skin trials at roughly 1–10 g a day: 2.5–10 g for 8–24 weeks in eight hydrolysate trials within a 2019 review of 11 studies, and a median of 3.5 g (range 1–10 g) across 10 trials in a 2025 review [9]. One serving here is 20 g, two to eight times the first range. The brand’s FAQ suggests 10–20 g a day “for results” [14]; we could not match that to a set of trials, and we did not compile joint-trial doses. Trials also used different collagen sources and forms [4], and this label does not say which peptide ingredient it contains.
Protein quality and safety
Collagen lacks tryptophan, an essential amino acid, so under the standard protein-scoring method it counts as an incomplete protein [10]. The pack says the same, so 18 g of collagen protein does not stand in for 18 g from meat, eggs or dairy. (One author of that paper declares research services for a maker of collagen supplements and another is affiliated with GELITA AG, a collagen-peptide producer; we cite it only for the tryptophan point, which the label also states.) The 2026 review reports collagen was generally well tolerated with few adverse events [6]. The label advises asking a healthcare practitioner first if you are pregnant, lactating, on medication or have a health condition [2].
Buy this for what it reliably is, a plainly labeled collagen powder with an NSF listing, not for a promised skin or joint result. The independent evidence for those results is thin, and a 20 g serving is larger than the doses reported in the skin reviews we cite.
Price and where it is sold
On Sep 25, 2026 Amazon’s listing for the 9.33 oz (265 g) canister, sold by Vital Proteins and shipped by Amazon, showed a one-time price of $18.65 and a Subscribe & Save price of $17.72 [12]. That is about $1.33 a serving on the label’s 14 servings, or $1.43 on Amazon’s 13. The brand’s own site listed the same size at $27.00 (about $1.93 a serving) or $22.95 on subscription, and the 19.3 oz size at $45.00 (28 servings, about $1.61 each) [1]. Prices move; read these as observations from that day.
Check which listing you open. Amazon also carries an “Advanced” version (with added hyaluronic acid and vitamin C), bundles and third-party sellers; a 19.3 oz plain listing we opened was sold by a third-party seller at $37.99. The brand says to look for “Ships from Amazon, Sold by Vital Proteins” [14].
Returns: Amazon marks this listing non-returnable for food-safety reasons, with a refund or replacement if it arrives damaged or defective and you send a photo through Your Orders [12]. The brand’s own store asks to be told of problems within 30 days of receipt for orders placed on vitalproteins.com, and says some returns may carry a restocking fee [13]. We found no money-back guarantee wording.
Who is behind it: Nestlé Health Science says it bought a majority stake in Vital Proteins in 2020 and later completed the final acquisition [16]. Nestlé’s 1 September 2026 announcement of the sale of its mainstream supplement business names seven brands, and Vital Proteins is not among them [16]; ownership can change, so check. The Certified B Corporation logo on the pack is a company-level standard, not a product test [17].
Who should look elsewhere
- Anyone who needs a complete protein source: collagen lacks tryptophan, and the pack says not to use it in place of dietary protein.
- Vegans, vegetarians and anyone avoiding beef-derived products; it is made from bovine hide.
- People with milk, fish or tree-nut allergies or on a low-sodium plan (110 mg a serving), who should read the exact pack they receive, since the 9.33 oz and 19.3 oz labels differ.
- Anyone expecting a specific skin or joint result. The independent evidence is thin, and joint trials mostly involved adults with a diagnosed joint condition.
- People who are pregnant or nursing, or who take prescription medicines, should ask a pharmacist or clinician first; the label says the same.
