The budget pick: 20 g of grass-fed bovine collagen per serving for roughly a dollar on Amazon, with a full amino acid profile, though it lacks a named third-party certification.

Our verdict
Hard to beat on price for a plain 20 g collagen, and more transparent than most thanks to the amino acid profile. The trade-off is the absence of third-party certification, so athletes and buyers who prioritize verified testing should pay more for Vital Proteins or Garden of Life.

Orgain's Grass Fed Collagen Peptides is the value option in this category. The ingredient list is a single line, collagen peptides (bovine), and a two-scoop serving delivers 20 g of type I and III collagen with 18 g protein, 70 calories and 100 mg sodium. Like Sports Research, Orgain prints a typical amino acid profile on the label, with about 4 g glycine, 2.4 g proline and 2 g hydroxyproline per serving.
The price is what stands out. The 1 lb tub holds about 22 servings and sells for around $21, roughly $0.96 per 20 g serving or $0.48 per 10 g of collagen, about half the cost of some premium brands. It is gluten free, made without dairy or soy ingredients, paleo friendly and IGEN non-GMO tested, and Orgain is a certified B Corporation.
What you do not get is independent contaminant or sport certification: we found no NSF, USP or Informed listing for this product, so its quality score is capped accordingly. As with every collagen, the evidence is modest; skin benefits reported in industry-funded trials are not consistently reproduced in high-quality independent studies, while joint trials suggest small-to-moderate relief for osteoarthritis pain.
Buyer feedback is broadly positive (4.5 stars from nearly 40,000 buyer ratings), and creators on TikTok highlight it as a budget find that mixes well into coffee. Amazon's review summary notes mixed opinions on taste and on how well it dissolves in cold water, and some buyers report nausea. Note that the brand labels a serving as two scoops, so the scoop in the tub is 10 g.

Testing & quality
Protein powders carry USDA Organic certification; the brand does not publish batch heavy-metal results, and a July 2026 proposed class action against Costco alleges heavy metals in its protein powder, which Orgain disputes.
