What Is Collagen and Why Does It Matter?
Collagen is the most abundant protein in the human body — making up approximately 30% of total protein and forming the structural framework of skin, tendons, ligaments, bones, and cartilage. After age 25, the body produces roughly 1–1.5% less collagen per year. By age 40, collagen production has declined significantly enough to affect skin elasticity, joint cushioning, and recovery from exercise.
Types of collagen relevant to supplements:
- Type I: Most abundant — skin, tendons, ligaments, bones. Found in bovine and marine sources.
- Type II: Cartilage and joints. Found in chicken sternum collagen.
- Type III: Skin and blood vessels. Often paired with Type I in bovine collagen.
- Type V: Hair, nails, and cell surfaces. Found in eggshell membrane.
- Type X: Joint cartilage. Found in eggshell membrane and chicken collagen.
The 5 Best Collagen Supplements

What Does the Research Actually Show?
The evidence for collagen supplementation is growing but still developing. Here is what the published data supports:
Skin: A 2019 systematic review in the Journal of Drugs in Dermatology (Choi et al.) analyzed 11 randomized controlled trials and found hydrolyzed collagen supplementation significantly improved skin elasticity, hydration, and dermal collagen density compared to placebo. Doses in studies ranged from 2.5g to 10g daily.
Joints: A 2016 study in Current Medical Research and Opinion (Clark et al.) found 10g/day of collagen hydrolysate significantly reduced joint pain in athletes compared to placebo over 24 weeks. Type II collagen at lower doses (10–40mg) has been studied specifically for osteoarthritis.
Tendons and connective tissue: The Shaw et al. 2017 study in the American Journal of Clinical Nutrition is the most cited — gelatin (collagen) supplementation with vitamin C, taken before exercise, significantly increased collagen synthesis markers in tendons.
Hair and nails: Evidence is more limited. A few small studies show modest improvements in nail growth rate and brittleness with collagen supplementation. Hair studies are largely anecdotal or industry-funded.
Effective doses: Most studies showing benefit used 10–15g/day of hydrolyzed collagen peptides. Very low doses (2–5g) may be insufficient for musculoskeletal or skin benefits.

Frequently Asked Questions
What is the best collagen supplement overall in 2026?
Vital Proteins Collagen Peptides is the best overall — 20g of NSF Certified, grass-fed bovine Type I and III collagen at a reasonable price. It has the broadest consumer and practitioner trust of any collagen brand.
How much collagen should I take per day?
Most studies showing benefit use 10–15g per day. For skin and joint support, 10g is a common starting dose. For tendon and athletic performance protocols, 15g pre-exercise with vitamin C is the research-supported approach.
Does collagen supplementation actually work?
The evidence is strongest for skin elasticity and hydration (multiple RCTs) and joint pain reduction in active individuals. Evidence for hair and nail benefits is weaker. Results vary by individual and are typically seen after 8–12 weeks of consistent use.
What is the difference between Type I, II, and III collagen?
Type I and III are found in skin, tendons, and bones — most relevant for skin, hair, nails, and general connective tissue. Type II is found in cartilage — most relevant for joint support. Most bovine collagen supplements provide Type I and III; chicken or multi-collagen products add Type II.
Is bovine or marine collagen better?
Both are effective sources of Type I collagen. Marine collagen has smaller peptides (potentially better absorption) and is preferred by pescatarians avoiding beef. Bovine collagen is more cost-effective and provides both Type I and III. Neither is clearly superior based on current evidence.
When is the best time to take collagen?
For general skin and joint support, timing is flexible — many people add it to morning coffee or smoothies. For athletic tendon support, 15–30 minutes before exercise with vitamin C is the protocol with the strongest research backing.
Can vegans take collagen supplements?
Standard collagen supplements are animal-derived. Vegan collagen boosters exist (vitamin C, lysine, proline, silica) but do not contain actual collagen. Vegan products support the body's own collagen production rather than supplying exogenous collagen peptides.
Do collagen supplements have side effects?
Collagen supplements are generally well-tolerated. Some people report mild digestive discomfort at higher doses. Marine collagen may cause reactions in those with fish allergies. Those with hypercalcemia should use caution with bone broth-based collagens.
