Best Collagen Supplements 2025
Evidence-based reviews for skin elasticity, joint health, and gut support
Understanding Collagen Supplementation
Collagen is the most abundant protein in the human body, providing structure to skin, bones, tendons, ligaments, and other connective tissues. As we age, natural collagen production declines by approximately 1% per year after age 25, contributing to visible signs of aging like wrinkles, joint stiffness, and reduced skin elasticity.
Collagen supplements provide hydrolyzed peptides, which are broken down into smaller amino acid chains for better absorption. Research published in journals like Nutrients and the Journal of Cosmetic Dermatology suggests that oral collagen supplementation may support skin hydration, elasticity, and joint comfort, though individual results vary.
Most clinical studies use doses of 10-20 grams daily for 8-12 weeks before observing benefits. It's important to set realistic expectations: collagen supplements support the body's natural processes but are not a cure for aging or joint conditions.
Quick Tip: Look for hydrolyzed collagen peptides with at least 10g per serving. Type I and III are best for skin and bones, while Type II targets joint cartilage. Taking collagen with vitamin C can enhance your body's natural collagen synthesis.

Collagen Buying Guide
Types of Collagen
Type I Collagen
Makes up 90% of your body's collagen. Found in skin, bones, tendons, and ligaments. Best for skin elasticity, bone strength, and wound healing.
Type II Collagen
Found primarily in cartilage. Targets joint health and mobility. Often sourced from chicken sternum.
Type III Collagen
Works alongside Type I in skin, muscles, and blood vessels. Supports skin firmness and elasticity.
Collagen Sources
- Bovine (Cow):Rich in Type I and III. Most common and affordable. Look for grass-fed sources.
- Marine (Fish):Primarily Type I. Smaller particles may absorb better. Good for pescatarians.
- Chicken:High in Type II. Best for joint-specific support.
- Eggshell Membrane:Contains Type I, V, and X. Includes other joint-supportive compounds.
Research on Collagen Benefits
Skin Health
Clinical studies published in the Journal of Cosmetic Dermatology show that 10-20g of collagen peptides daily for 8-12 weeks may improve skin hydration and elasticity. A 2019 review in Nutrients found positive effects on skin aging markers, though results varied by individual.
Realistic expectation: Modest improvements in skin texture and hydration, not dramatic wrinkle reversal.
Joint Health
Research in Osteoarthritis and Cartilage suggests that collagen supplementation may support joint comfort in individuals with joint stiffness. Type II collagen specifically has shown promise for cartilage support in clinical trials.
Realistic expectation: May support joint comfort, not a replacement for medical treatment of arthritis.
Gut Health
Emerging research suggests collagen may support intestinal barrier function. The amino acid glycine (abundant in collagen) plays a role in gut lining integrity, though clinical evidence is still limited.
Realistic expectation: Promising but preliminary. More research needed.
How to Take Collagen
- Dosage: 10-20g daily for skin and joint benefits (based on clinical research)
- Timing: Can be taken any time of day. Consistency matters more than timing
- With Vitamin C: Taking with vitamin C-rich foods or supplements may enhance collagen synthesis
- How to mix: Dissolves in hot or cold liquids. Add to coffee, smoothies, oatmeal, or water
- Timeline: Most studies show benefits after 8-12 weeks of consistent use
What to Look For
- Hydrolyzed collagen peptides (better absorption than unhydrolyzed)
- At least 10g per serving (clinical studies use 10-20g)
- Clean sourcing (grass-fed for bovine, wild-caught for marine)
- Third-party testing when possible
- Minimal additives and fillers
- Appropriate collagen type for your goals (I/III for skin, II for joints)
What to Avoid
- Products making cure or disease treatment claims
- Extremely low doses (under 5g per serving)
- Excessive added sugars or artificial ingredients
- Unverified sourcing or quality claims
- Products without clear collagen type information
