Why This Comparison Matters
Vital Proteins and Sports Research are the two best-selling collagen peptide brands on Amazon. Vital Proteins has the brand recognition advantage - it is in every Whole Foods and has heavy social media marketing. Sports Research has built a loyal following among value-conscious buyers who want comparable quality at a lower price.
Both products deliver hydrolyzed bovine collagen peptides (primarily types I and III) from grass-fed sources. The active ingredient is functionally the same. The differences are in third-party testing, sourcing documentation, price, and brand trust.
We scored both on our four-factor system to see if the brand premium is justified.
Detailed Score Breakdown
Vital Proteins Collagen Peptides Original
Vital Proteins
20g collagen peptides per serving (2 scoops) - exceeds the 10-15g joint/muscle evidence dose and far exceeds 2.5-5g skin dose. Bovine hide sourced, type I and III.
Certified Paleo, Whole30 Approved. No third-party testing certification (NSF, USP, Informed Sport) publicly documented. GMP-compliant facility per brand claims. No contaminant testing verified externally.
$0.73/day at a 10g effective dose (1 scoop) - mid-range for a market-leading bovine collagen. Full 20g serving runs $1.46/day.
Source (bovine hide) disclosed. Collagen types (I and III) disclosed. Amino acid profile published on label. No proprietary blends. No third-party cert displayed.
The market-share leader and likely the most-researched consumer collagen brand in the US. Good transparency on source and type, but lacks independent third-party quality testing (NSF, USP) that would elevate this to an A-tier product.
Sports Research Collagen Peptides
Sports Research
11g collagen peptides per scoop - within the evidence-supported range for joint and muscle benefits (10-15g). Bovine hide, type I and III.
Informed Sport Certified (batch-tested for banned substances) and non-GMO verified. Pasture-raised, grass-fed bovine sourcing. Third-party testing gives this a meaningful quality edge over most competitors.
$0.47/day at one 11g scoop - among the best value in the category for an Informed Sport certified product
Source (grass-fed, pasture-raised bovine hide) disclosed. Types I and III noted. Informed Sport cert displayed. Full amino acid profile available. No proprietary blends.
Informed Sport certification is rare in the collagen category and provides real assurance of what is - and is not - in the product. Grass-fed bovine sourcing. The most quality-credentialed product at a competitive price point.
How We Compared These Products
Every product in our database is scored on four equally-weighted categories: clinical evidence quality, third-party testing and purity verification, cost per clinically effective dose (not cost per pill), and label transparency. These scores combine into an overall letter grade from A+ through F.
Cost per effective dose is calculated using the clinically studied dose from published research, not the manufacturer's suggested serving. If a product requires multiple servings to reach the dose used in clinical trials, that cost is reflected in the value score.
