Key Takeaways
- Both deliver roughly 20 g of bovine hydrolyzed collagen per two-scoop serving, making amino acid dose essentially equivalent on paper.
- No published, independent RCT exists for either brand's specific product; underlying collagen evidence comes from proprietary hydrolysate trials (VERISOL, Peptan), not these powders.
- Vital Proteins carries NSF certification claims on select SKUs; Orgain does not consistently claim equivalent third-party certification for its collagen line. Verify SKU-level status at NSF's public database.
- The Clean Label Project's 2020 collagen report found detectable heavy metals in many collagen powders across the market; neither brand is categorically exempt from contamination risk.
- Orgain typically costs less per gram of collagen at major retailers, meaning the Vital Proteins premium is driven by brand positioning, not proven superior outcomes.

Evidence Ledger: What the Research Actually Supports
| Claim | Best Evidence Type | Effect Direction | Confidence |
|---|---|---|---|
| Hydrolyzed collagen improves skin elasticity and hydration | Multiple small RCTs, most manufacturer-funded (e.g., Proksch et al. 2014 on VERISOL) | Modest positive | Moderate (for specific hydrolysates, not these brands) |
| Collagen peptides reduce joint pain in athletes | RCTs including Shaw et al. 2017 on gelatin/vitamin C; Clark et al. 2008 on UC-II | Small to moderate positive | Low to Moderate (evidence is hydrolysate-specific) |
| Hydroxyproline-containing peptides detected in plasma after ingestion | Human pharmacokinetic studies (Iwai et al. 2005) | Confirmed absorption | High (for absorption, not clinical effect) |
| Collagen supplementation builds muscle | Small RCTs in older adults (Zdzieblik et al. 2015) | Modest positive when combined with resistance training | Low to Moderate (inferior to whey for leucine content) |
| Orgain or Vital Proteins specifically improve any clinical endpoint | No product-specific published RCT found | Unknown | Very Low |
| Heavy metals present in some collagen powders | Clean Label Project 2020 independent testing | Contamination detected in subset of brands tested | Moderate (methodology not peer-reviewed but testing real) |
How Hydrolyzed Collagen Works (With Real Numbers)
Collagen peptides are produced by enzymatic hydrolysis of bovine (or marine) collagen. This breaks triple-helix collagen fibers into shorter chains, typically 2,000 to 5,000 daltons molecular weight, compared to intact collagen at roughly 300,000 daltons. The smaller chains survive gastric transit and are absorbed as di- and tripeptides, particularly Pro-Hyp and Hyp-Gly sequences.

Try the BMI Calculator →Iwai et al. (2005) detected plasma hydroxyproline peptides peaking approximately 2 hours post-ingestion in human subjects given hydrolyzed collagen. These peptides are proposed to stimulate fibroblast activity and collagen synthesis in skin and connective tissue, though the precise mechanism from plasma peptide to dermal collagen deposition is not fully established.
Proksch et al. (2014) showed significant improvements in skin elasticity and hydration at 2.5 g per day of VERISOL collagen peptides over 8 weeks in a 69-person RCT. Crucially, VERISOL is a specific, proprietary Gelita hydrolysate. Neither Orgain nor Vital Proteins uses VERISOL or is manufactured to that hydrolysate specification. Extrapolating VERISOL data to these products is not scientifically supported, though commodity bovine hydrolysate likely has overlapping peptide composition.
What the mechanism does NOT prove: absorption of hydroxyproline peptides does not guarantee fibroblast stimulation in vivo at physiological doses, and fibroblast stimulation in cell culture does not guarantee measurable skin or joint outcomes in humans. Each step in that chain carries uncertainty.
Amino Acid Profile and Dose Comparison
Collagen protein is characterized by an unusual amino acid composition. Approximately one third of residues are glycine. Proline and hydroxyproline together account for another 20 to 22% of residues. This means collagen is rich in these three amino acids and low in essential amino acids, particularly leucine (less than 1% by weight), which limits its utility as a primary protein for muscle protein synthesis.
| Metric | Orgain Collagen Peptides (unflavored) | Vital Proteins Collagen Peptides (unflavored) |
|---|---|---|
| Collagen per serving | 20 g (2 scoops) | 20 g (2 scoops) |
| Protein per serving | 18 g (label figure) | 18 g (label figure) |
| Calories per serving | Approx. 70 | Approx. 70 |
| Glycine (estimated) | Approx. 6 to 7 g (based on collagen composition norms) | Approx. 6 to 7 g (based on collagen composition norms) |
| Leucine | Low (under 1 g, typical for collagen) | Low (under 1 g, typical for collagen) |
| Source | Bovine hide | Bovine hide |
| Type | Type I and III | Type I and III |
| Additional ingredients (unflavored) | Minimal; check label for specific SKU | Minimal for unflavored; some SKUs add vitamin C |
Sourcing, Processing, and Purity
Both brands source from bovine hide, primarily from cattle raised in Brazil or other large-scale agricultural regions. Vital Proteins markets its sourcing as grass-fed and pasture-raised, a claim the brand has promoted heavily. Orgain uses similar language on some products.
The practical significance of grass-fed versus grain-fed for collagen purity is unclear. Collagen is a structural protein, not a fat-soluble nutrient, so fatty acid profile differences between grass-fed and conventional cattle (which are real for beef fat) have little bearing on the collagen peptide powder itself. The more meaningful sourcing question is whether the raw hide undergoes heavy metal testing and whether the hydrolysis process is validated for consistency of molecular weight distribution.
Vital Proteins reports NSF Certified for Sport status on some products (this applies to select SKUs, not the entire line). NSF Certified for Sport tests for over 270 substances banned in sport and conducts facility audits. This is a meaningful certification for athletes who face drug testing, though it does not test for heavy metals at food safety thresholds specifically.
What Most Pages Get Wrong About Collagen Comparisons
Most comparison articles treat these two products as clearly distinct when they are actually sourced from similar commodity bovine hydrolysate supply chains, likely from a limited pool of large-scale collagen ingredient suppliers (Gelita, Rousselot, and a handful of others supply most of the US market). The brand on the label does not determine the hydrolysate specification.
Second, almost every article cites collagen clinical studies as if they validate these specific products. They do not. The Proksch VERISOL data, the Shaw gelatin-plus-vitamin C joint data, and the Zdzieblik sarcopenia data are all hydrolysate-specific or formulation-specific. Generic bovine powder at 20 g per day may have similar effects or may not. The literature does not resolve this for commodity products.
Third, the heavy metal issue is almost never discussed. The Clean Label Project's 2020 report tested 28 collagen products and found detectable lead, arsenic, cadmium, and mercury in a substantial portion of products tested. The methodology was not peer-reviewed and detection does not equal harm (levels matter), but the absence of routine ICP-MS COA documentation from most brands is a real gap that neither Orgain nor Vital Proteins consistently addresses in public-facing documentation.
Honest Head-to-Head Table
| Criterion | Orgain Collagen Peptides | Vital Proteins Collagen Peptides | Winner |
|---|---|---|---|
| Collagen dose per serving | 20 g | 20 g | Tie |
| Third-party certification (select SKUs) | Not consistently claimed for collagen line | NSF Certified for Sport on select SKUs | Vital Proteins (narrow advantage) |
| Price per gram of collagen (typical retail) | Lower cost per gram | Higher cost per gram | Orgain |
| Product-specific RCT evidence | None | None | Tie (neither wins) |
| Sourcing transparency | Bovine hide; grass-fed claims vary by SKU | Grass-fed, pasture-raised marketed consistently | Slight Vital Proteins edge on marketing; real-world difference unclear |
| Retail availability | Target, Costco, Amazon | Target, Costco, Amazon, Whole Foods | Vital Proteins (slightly broader) |
| Heavy metal COA transparency | Not routinely published publicly | Not routinely published publicly | Tie (neither fully transparent) |
| Added vitamin C in formulation | Not in unflavored base | Some SKUs include vitamin C (relevant for collagen synthesis pathway) | Context-dependent; see Shaw et al. 2017 for vitamin C rationale |
Why Heat, pH, and Storage Matter (The Chemistry)
Hydrolyzed collagen peptides are significantly more stable than intact collagen because enzymatic hydrolysis has already broken the triple helix. This means dissolving them in hot coffee or tea does not meaningfully denature them further. The relevant degradation concern is not temperature during use but conditions during storage and shipping.
Peptide powders are hygroscopic: they absorb atmospheric moisture, which accelerates clumping and provides a substrate for microbial growth. The practical rule is to store in a sealed container away from humidity, not in a refrigerator where condensation on a warm-room entry cycle increases moisture exposure.
Vitamin C is often co-formulated with collagen or recommended alongside it because ascorbic acid is a required cofactor for prolyl hydroxylase, the enzyme that hydroxylates proline to hydroxyproline during endogenous collagen synthesis. Shaw et al. (2017) demonstrated this pathway relevance in a gelatin-plus-vitamin C RCT showing increased collagen synthesis markers in athletes. Whether supplementing with 50 mg vitamin C alongside collagen makes a meaningful difference when most people are not scorbutic is debated, but the biochemistry is sound. Neither Orgain plain nor Vital Proteins plain unflavored adds vitamin C to address this pathway.
Label and COA Literacy: How to Judge the Product Yourself
When evaluating either product, look for these specific items:
| What to Look For | Where to Find It | What a Good Answer Looks Like |
|---|---|---|
| Molecular weight of hydrolysate | COA from manufacturer or brand | 2,000 to 5,000 daltons for optimal absorption; some brands specify average MW |
| Heavy metal testing | COA with ICP-MS results | Lead under 0.5 mcg per serving (CA Prop 65 threshold for daily supplements), ideally under detection limit |
| Third-party certification | NSF, Informed Sport, or USP seal on label | Verify the specific product at nsf.org/certified-products, not just the brand name |
| Amino acid panel | Full amino acid profile on label or COA | Glycine roughly 25 to 33% of total amino acids; hydroxyproline present; low leucine expected |
| Protein per gram of collagen | Label math: protein divided by collagen listed | Hydrolyzed collagen is roughly 90% protein by weight; large gaps suggest filler or measurement methodology issues |
| Degraded product appearance | Visual inspection | Severe yellowing beyond light cream, hard clumping resistant to stirring, or off smell suggest moisture compromise or age |
Neither Orgain nor Vital Proteins publishes full COA documentation proactively on their consumer-facing websites as of this writing. Both can be contacted directly for batch COAs. If a brand refuses to provide a COA with heavy metal results for a protein powder you consume daily, that is a meaningful flag regardless of brand prestige.
How Both Compare to Actual Alternatives
| Product Type | Collagen Peptides (Orgain or Vital Proteins) | Whey Protein Isolate | Specific Hydrolysate (e.g., VERISOL) |
|---|---|---|---|
| Leucine per 20 g | Under 1 g | Approx. 2 g | Similar to generic collagen |
| Muscle protein synthesis | Weak stimulator | Strong stimulator | Weak stimulator |
| Skin/joint evidence | Extrapolated from other hydrolysates | Minimal relevant evidence | Direct RCT evidence (VERISOL: Proksch 2014) |
| Price per 20 g serving | Low to moderate | Moderate | Higher (specialty product) |
| Where collagen peptides WIN | Tasteless dissolution, glycine content, collagen-specific amino acids | Collagen loses here | Collagen loses on evidence strength |
| Where collagen peptides LOSE | Muscle building, essential amino acid completeness, product-specific evidence | Wins on protein quality | Commodity collagen loses on evidence specificity |
FAQ
Are Orgain collagen peptides and Vital Proteins the same product?
No. Both are bovine-derived hydrolyzed collagen type I and III, but they differ in glycine and proline content per serving, certifications, third-party testing claims, added ingredients, and price per gram of collagen.
Which has more collagen per serving, Orgain or Vital Proteins?
Vital Proteins lists 20 g collagen per two-scoop serving. Orgain lists 20 g per two-scoop serving as well. Serving sizes match on paper, but the amino acid profile breakdown differs slightly and should be checked on current product labels.
Is Vital Proteins third-party tested?
Vital Proteins claims NSF certification for some products. Always verify the specific SKU at NSF's public database rather than relying on brand marketing, as certification status can change between product runs.
Does either brand actually improve skin or joints based on clinical evidence?
Neither brand has funded a published RCT on their own product. The underlying evidence for hydrolyzed collagen comes from trials on specific branded hydrolysates like VERISOL and BioCell Collagen, not generic bovine collagen powder. Effects are modest and evidence is manufacturer-funded in most cases.
Which is better value, Orgain or Vital Proteins?
Orgain typically costs less per gram of collagen than Vital Proteins, though pricing varies by retailer. Vital Proteins commands a premium partly due to branding and marketing partnerships rather than demonstrably superior clinical outcomes.
Do collagen peptides from either brand actually get absorbed?
Hydrolyzed collagen is absorbed as di- and tripeptides, particularly hydroxyproline-containing peptides that are detected in plasma. However, absorption does not guarantee tissue incorporation or the clinical outcomes shown in funded trials.
Does Orgain collagen have any additives?
The unflavored Orgain collagen peptides product is minimally formulated, but some Orgain collagen products include organic cacao, probiotics, or other ingredients. Always read the label for the specific SKU you are purchasing.
Is Vital Proteins worth the higher price?
Not demonstrably on evidence. Both deliver similar amino acids at similar doses. Vital Proteins' premium reflects brand recognition and distribution scale, not proven superior clinical outcomes in head-to-head trials.
What is the glycine content in each product?
Collagen is roughly 33% glycine by amino acid composition. At 20 g collagen, a rough estimate is about 6 to 7 g glycine per serving for both products, but exact figures depend on the specific hydrolysate source and should be confirmed on current nutrition labels.
Can I mix either product with hot coffee?
Yes, both dissolve in hot liquids. Hydrolyzed collagen peptides are heat-stable up to typical beverage temperatures. The concern is prolonged high-heat processing, not mixing a scoop into coffee.
Are there heavy metal contamination risks in either product?
The Clean Label Project tested collagen products and found detectable heavy metals including lead in some samples across multiple brands. Neither Orgain nor Vital Proteins is immune to this risk. Look for COA documentation with ICP-MS heavy metal testing.
