Understanding Collagen Peptides
Collagen is the most abundant protein in the human body, providing structure and strength to connective tissues like skin, bones, tendons, and ligaments. As we age, our natural collagen production declines, leading to common signs of aging such as wrinkles, joint stiffness, and weakened bones. Collagen peptides, or hydrolyzed collagen, are smaller, more easily digestible fragments of collagen that can be absorbed more efficiently by the body than whole collagen.
Types of Collagen and Their Benefits
Not all collagen peptides are the same. Supplements typically focus on a few specific types, each with its own benefits:
- Type I: The most abundant type, found in skin, bones, tendons, and ligaments. It provides tensile strength and is best for skin and bone health.
- Type II: Primarily found in cartilage, this type is key for joint support and can help alleviate joint pain and inflammation, particularly in cases of osteoarthritis.
- Type III: Often paired with Type I, it's present in the skin, muscles, and blood vessels, contributing to elasticity and flexibility.
- Multi-Collagen: Products containing a blend of multiple types (I, II, III, V, and X) offer comprehensive benefits for skin, hair, joints, and gut health.
Sourcing and Hydrolyzation
Collagen peptides are derived from various animal sources. The source and processing method impact the supplement's profile:
- Bovine Collagen: Sourced from the hide and bones of cows, this is a common source of Type I and III collagen. Reputable brands, like Transparent Labs, use grass-fed, pasture-raised cattle.
- Marine Collagen: Derived from the skin and scales of fish, this is primarily Type I collagen. Some research suggests marine collagen may be more easily absorbed due to its smaller particle size. Further Food offers a high-quality marine option.
- Chicken Collagen: A source of Type II collagen, making it particularly beneficial for joint-related concerns.
- Hydrolyzed vs. Undenatured: The process of hydrolyzing collagen into smaller peptides is crucial for bioavailability. Undenatured Type II collagen is used in some joint-specific formulas, like Momentous, at lower doses.

How to Choose the Right Collagen for You
Choosing the best collagen supplement depends on your specific health goals, dietary needs, and lifestyle.
For Skin, Hair, and Nails: If your primary focus is improving skin hydration, elasticity, and supporting hair and nail growth, look for supplements rich in Type I and III collagen. Vital Proteins and Sports Research are excellent choices in this category.
For Joint and Cartilage Support: Those with joint discomfort or athletes looking to protect their cartilage should opt for a supplement with Type II collagen. Momentous Collagen Peptides, with its Fortigel, is specifically formulated for this purpose.
For Comprehensive Wellness: A multi-collagen product, like Ancient Nutrition's, is ideal for individuals seeking broader benefits that address multiple areas of the body simultaneously.
Consider Your Dietary Needs: If you follow a pescatarian diet, marine collagen from brands like Further Food is a great alternative to bovine options. Vegans can use collagen boosters with vitamins and plant extracts, such as Ora Organic Aloe Gorgeous, though these don't contain actual collagen.
Third-Party Testing Matters: Since the FDA does not regulate supplements, relying on third-party tested products ensures you're getting a safe, pure, and accurately dosed product. Look for certifications like NSF Certified for Sport or Informed-Choice, especially if you're an athlete.
Conclusion: Making Your Choice
Selecting the best collagen peptides involves considering your personal health goals, product quality, and budget. Whether you choose a high-potency powder like Transparent Labs for maximum purity, a multi-source blend from Ancient Nutrition for comprehensive benefits, or a specialized formula like Momentous for joint support, consistency is key to seeing results. Always choose hydrolyzed collagen peptides for optimal absorption and look for supplements that include synergistic ingredients like Vitamin C to maximize your body's ability to synthesize collagen.
