How Does Collagen Help Joint Health? These Facts Might Surprise You!


Collagen is the most abundant protein in the human body and is a major component of connective tissues such as tendons, ligaments, cartilage, bones, and skin. As we age, our bodies produce less collagen, leading to joint stiffness, bone loss, and wrinkled skin.

Collagen supplements have surged in popularity in recent years due to claims that they can improve skin health and relieve joint pain. But does consuming more collagen really benefit our joints? Let’s take a closer look at what collagen is, how it affects joint health, and whether taking collagen supplements is worth it.  

How Does Collagen Help Joint Health?

Collagen is a key building block of healthy cartilage, which covers the ends of bones within joints to allow them to slide and glide smoothly. Cartilage is made up of collagen fibers embedded in a flexible ground substance.

Collagen And Joint Health

With age and wear and tear, cartilage can deteriorate and become thin and ragged. This loss of cartilage cushioning is a hallmark of osteoarthritis. Consuming collagen supplements may help:

  • Boost collagen production: Ingesting collagen peptides provides the raw materials for your body to replenish depleted collagen. Supplements with collagen hydrolysate contain bioactive collagen peptides that are easily absorbed. 
  • Support cartilage repair: Several studies indicate collagen supplements stimulate cells called chondrocytes to produce new cartilage components. This may counteract cartilage breakdown in osteoarthritis.
  • Reduce inflammation: Research shows collagen supplements suppress inflammatory cytokines in the joints. This inflammation-dampening effect may also promote pain relief.
  • Improve joint mobility: Clinical studies found collagen supplements improved joint function and flexibility in athletes and those with osteoarthritis after just a couple of months.

What Are The Best Sources Of Collagen For Joint Health?

The collagen peptides found in supplements are derived from four main sources:

  • Bovine (cow or beef) collagen: A rich source extracted from cow hides and bones. Ensure the cattle are grass-fed for higher quality.
  • Marine (fish) collagen: Derived from the scales and skins of fish like cod, salmon, or tilapia. Has a low molecular weight for easy absorption.  
  • Egg shell membrane collagen: Extracted from the thin lining of egg shells. Contains beneficial bioactive proteins.
  • Chicken collagen: Derived from chicken feet, bones, or cartilage. Has similar benefits as bovine collagen.

Look for a hydrolyzed collagen powder that provides around 10-15 grams of collagen peptides per serving. Powdered collagen blends easily into smoothies or water. Ready-to-drink collagen beverages are also available for convenience.

Other Natural Ways To Boost Collagen Production

In addition to collagen supplements, other evidence-based ways to increase collagen levels include:

  • Eat collagen-boosting foods: Proline-rich foods like citrus fruits, leafy greens, eggs, and berries support natural collagen synthesis. Vitamin C is also key.
  • Apply vitamin C topically: Creams with vitamin C may help stimulate collagen growth when applied to the skin. 
  • Do resistance training: Lifting weights places controlled stress on the muscles and tendons, triggering increased collagen production.
  • Get enough sleep: Our circadian rhythm guides collagen production. Not getting 7-9 hours of sleep at night disrupts this cycle.
  • Quit smoking: Smoking dramatically depletes collagen levels and accelerates aging of the skin and joints.
  • Manage stress: Chronic stress raises cortisol, which can inhibit collagen production and increase inflammation.

Early research indicates supplemental collagen may help alleviate joint pain, improve flexibility, and support cartilage health by boosting natural collagen production. Consuming 10-15 grams per day of multi-source collagen powder provides an easy way to get more of this important protein in your diet.

Along with collagen supplements, eating collagen-rich foods, exercise, proper sleep, and stress reduction also support healthy collagen levels for vibrant skin, strong bones, and smooth joint movements. However, speak to your doctor before starting any new supplements.


Q: What are the most common types of collagen?

A: The major types are: Type I (skin/tendon/bone collagen), Type II (cartilage collagen), and Type III (supports Type I). Collagen supplements usually contain a mix of Types I and III. 

Q: When is the best time to take collagen supplements?

A: Most experts recommend taking collagen supplements first thing in the morning or at night before bed on an empty stomach. This supports maximum absorption by the intestines.

Q: How long does it take for collagen supplements to work?

A: Research shows collagen supplements may start providing benefits in as little as a few weeks. But most studies suggest taking collagen consistently for 2-3 months to see the best results. 

Q: Are collagen supplements safe?

A: Collagen supplements are generally safe for most people. However, some people may experience mild side effects like an upset stomach, bad taste, or feeling full. Those with food sensitivities should consult their doctor before trying collagen peptides.

Q: Do collagen supplements really reduce wrinkles? 

A: Clinical studies show mixed evidence of collagen and wrinkles. But many dermatologists and users report improved skin elasticity and hydration from taking collagen daily. More research is still needed.
