Understanding the Structural Roles of Collagen Type 1 and 3
Sourcing collagen peptides for nutraceutical or pharmaceutical formulations often comes down to one core question: which type delivers the right structural support for your target application? Collagen Type 1 and Type 3 are the two most abundant fibrillar collagens in the human body, and they play distinct yet complementary roles in tissue integrity, skin elasticity, bone strength, and blood vessel structure. For overseas buyers — whether you are a purchasing manager evaluating batch consistency, an R&D developer comparing molecular weight profiles, or a QA specialist reviewing certification dossiers — understanding the functional differences between these two collagen types is essential for selecting the right raw material. This article breaks down their structural roles, typical specifications, and practical sourcing considerations for food, supplement, and pharmaceutical applications.
What Are Collagen Type 1 and Type 3, and Why Do They Matter for Formulators?
Collagen Type 1 is the most prevalent collagen in the body, found in skin, bones, tendons, and ligaments. It provides tensile strength and structural scaffolding. Collagen Type 3, often co-localized with Type 1, is abundant in extensible tissues such as skin, blood vessels, and internal organs — it contributes to tissue elasticity and flexibility. For product developers, the ratio of Type 1 to Type 3 in a raw material can influence gel strength, solubility, and bioactivity. A common sourcing pain point is batch-to-batch consistency in this ratio, which directly affects end-product performance. Beyond Biopharma, a Shanghai-based manufacturer with over 10 years of experience in the collagen peptide and gelatin industry, addresses this by maintaining strict process controls and providing detailed COAs for every batch.
How Are Collagen Type 1 and Type 3 Produced and Processed?
Both collagen types are typically extracted from bovine, porcine, or marine sources through enzymatic hydrolysis. The process involves breaking down raw collagen into smaller peptides while preserving the amino acid profile and bioactive sequences. For Type 1, common sources include bovine hide and fish skin; for Type 3, bovine bone and certain fish scales are used. The degree of hydrolysis determines molecular weight — lower molecular weight peptides (2,000–5,000 Da) are associated with faster absorption and higher solubility. Beyond Biopharma uses fully automatic production lines with GMP clean workshops, stainless-steel sealed piping, and automated temperature/pH control to ensure consistent peptide profiles across batches. Their product lines include Edible Gelatin and Pharmaceutical Gelatin, which are rich in Type 1 collagen, as well as Undenatured Collagen Type II for joint health applications.

Applications and Recommended Solutions for Collagen Type 1 and Type 3
Selecting the right collagen type depends on your target application:
- Food & Gummies/Softgels: Type 1 collagen from bovine or fish gelatin (Bloom 150–260) provides the gel strength and clarity needed for gummy confections and softgel capsules. Beyond Biopharma offers Halal and Kosher verified fish gelatin for clean-label formulations.
- Hard & Soft Capsules: Pharmaceutical-grade Type 1 gelatin (bovine bone) with high bloom and viscosity is ideal for hard capsules. For softgels, ultra-high-viscosity gelatin ensures shell integrity.
- Sports Nutrition & Joint Health: Type 1 collagen peptides support tendon and ligament recovery, while Type 3 contributes to skin and vascular health. For joint-specific applications, Undenatured Collagen Type II is a clinically supported option. Beyond Biopharma also supplies bovine chondroitin sulfate sodium and glucosamine HCl for comprehensive joint health formulas.
- Beauty-from-Within: Low molecular weight fish collagen peptides (Type 1) are preferred for skin elasticity and hydration. Type 3 collagen supports dermal matrix structure.
- Plant-Based & Vegan Formulations: For allergen-free and vegan products, Beyond Biopharma offers Plant Protein Peptide alternatives (pea, rice, soy) that mimic the amino acid profile of collagen without animal sources.

Frequently Asked Questions About Collagen Type 1 and Type 3
Q: What is the main difference between Collagen Type 1 and Type 3?
A: Collagen Type 1 provides tensile strength and is abundant in skin, bones, and tendons. Collagen Type 3 supports elasticity and is found in skin, blood vessels, and internal organs. They often work together in tissues.
Q: Can I get a blend of Collagen Type 1 and Type 3 from a single supplier?
A: Yes. Many collagen peptide products naturally contain both types, especially those derived from bovine hide or fish skin. Beyond Biopharma can provide COAs showing the specific Type 1/Type 3 ratio per batch.
Q: What molecular weight is best for absorption of Type 1 collagen?
A: Lower molecular weight peptides (2,000–5,000 Da) are generally associated with faster absorption. Fish collagen peptides often have lower molecular weights compared to bovine sources.
Q: Are there vegan alternatives to Collagen Type 1 and Type 3?
A: Yes. Plant protein peptides from pea, rice, or soy can be formulated to mimic the amino acid profile of collagen. Beyond Biopharma offers plant-based hydrolyzed protein peptides for vegan and allergen-free applications.
Q: What certifications should I look for when sourcing collagen Type 1?
A: Key certifications include ISO 9001, FDA registration, Halal, Kosher, and BSE-free status for bovine sources. Beyond Biopharma holds these certifications and provides full documentation.
Q: How do I ensure batch consistency for collagen Type 1 and Type 3?
A: Request a Certificate of Analysis (COA) for each batch, covering molecular weight, protein content, bloom, viscosity, and heavy-metal testing. Beyond Biopharma provides COAs with every shipment.

Mike
Physical TherapistI’ve been using this type 1 and 3 collagen for about three months now, and I’m genuinely impressed. As a PT, I’m always looking for something to help my patients with joint recovery, but I started taking it myself for my own creaky knees after long shifts. The difference in my morning stiffness is real—I can actually squat down to tie my shoes without groaning. Plus, my nails aren’t splitting anymore. Tastes neutral in my coffee too.
Sarah
Graphic DesignerHonestly, I bought this on a whim because I kept seeing ads about collagen for skin elasticity. I’m a designer so I spend way too many hours staring at screens, and my face was starting to look a bit… tired. After a month of mixing this into my morning smoothie, I feel like my skin has a little more bounce? Hard to prove scientifically, but my coworker actually asked if I changed my skincare routine. Only giving 4 stars because the scoop is tiny and I wish the jar was bigger.
Tom
FirefighterNot gonna lie, I was skeptical. My wife bought this for me because I wreck my shoulders and back on the job. I’ve been taking it for six weeks now and I swear my recovery time after a heavy shift has improved. I’m not saying it’s magic, but I’ve had fewer aches in my rotator cuff and my joints don’t crack as much when I’m hauling hose. Mixes fine in my post-workout shake, no weird aftertaste. Worth a shot if you’re hard on your body.
Emma
High School TeacherI started taking this hoping it would help with some joint pain from standing all day in the classroom. It’s okay—I do think my hair looks a little shinier, which is nice. But I haven’t noticed a huge difference in my knees yet after two months. Maybe I need to give it more time. The powder dissolves pretty well in hot tea, but it clumps if I try cold water. Not a bad product, just not a miracle worker for me personally.
