Key Takeaways
- For targeted benefits such as improving skin appearance or joint comfort, collagen supplements offer more consistent results due to standardized dosing and easy absorption.
- Collagen supplements provide concentrated collagen peptides that can support gut, joint, and skin health.
- Bone broth provides collagen, along with minerals and amino acids, in a whole-food form; however, nutrient levels vary depending on the preparation method.
Bone broth and collagen supplements are rich in nutrients that support gut, joint, and skin health. Collagen supplements provide a concentrated form of the protein that supports the structure of skin, bones, and connective tissues. Bone broth provides collagen along with minerals and amino acids.
Collagen Supplements Support Gut Health
Collagen supplements have stronger and more consistent research supporting gut health benefits, though bone broth may provide supportive nutrition as part of a balanced diet.
- Supports gut barrier function and reduces inflammation: Studies on collagen peptides suggest they support gut barrier function and may help reduce inflammation.
- May improve digestive symptoms: Some small clinical studies have reported improvements in digestive symptoms in people with certain digestive conditions, including ulcerative colitis.
Bone broth provides collagen in the form of gelatin, along with amino acids and minerals. Although there are fewer studies examining the effects of drinking bone broth on gut health, recent research suggests that its nutrients may help strengthen the gut barrier, reduce inflammation, and enhance nutrient absorption.
Collagen Also Contributes to Joint Health
People seeking targeted joint support may benefit from collagen supplements.
- Supports connective tissue health: Collagen supplements provide a consistent dose of amino acids that support connective tissues, such as cartilage—the flexible tissue that cushions the ends of bones and allows smooth joint movement.
- Supports natural collagen production: Hydrolyzed collagen breaks down into smaller peptides that the body can easily absorb. These peptides may also help the body increase its own collagen production.
- May reduce joint pain and stiffness: Clinical studies have shown that collagen supplementation may help reduce joint pain and stiffness in individuals with osteoarthritis and in physically active adults.
Bone broth contains collagen along with naturally occurring compounds such as glucosamine and chondroitin, which support joint structure and function. However, the nutrient content of bone broth varies significantly depending on the preparation method.
One analysis found that bone broth provided lower, less reliable levels of amino acids than therapeutic doses of collagen supplements.
Opt for Collagen Supplements for Skin Health
For skin-focused goals such as improving firmness and reducing fine lines and wrinkles, collagen supplements offer the most reliable results.
- Improves skin elasticity: Multiple studies show that taking collagen peptides can increase skin elasticity, reduce the appearance of wrinkles, and improve skin hydration.
- Supports visible skin improvements: Research suggests that taking 2.5 to 10 grams of collagen daily for 8 to 12 weeks may lead to visible skin improvements.
Bone broth contains amino acids that may support skin health, but studies have not directly tested bone broth’s effects on skin appearance. One small study found that a collagen-rich chicken soup improved skin elasticity and skin tone; however, more research is needed to determine whether bone broth offers the same benefits.

Collagen Supplements: Uses and Benefits
Collagen is the most abundant protein in the human body. It provides structure and support for skin, hair, nails, bones, and connective tissues, including tendons, ligaments, and cartilage.
The body naturally produces collagen, but production slows and decreases with age. As collagen levels decline, wrinkles may develop, and joints may become stiff and painful.
Collagen supplements are made by breaking down animal tissues into a fine powder through a process called hydrolysis, which converts large protein molecules into smaller pieces called peptides. These collagen peptides are more easily absorbed and utilized by the body.
Possible benefits of collagen supplementation include:
- Improved skin elasticity and reduced wrinkle appearance
- Stronger nails and hair
- Reduced joint pain and stiffness
- Support for bone strength
- Support for gut health
Bone Broth: Uses and Benefits
Bone broth is a traditional food made by simmering animal bones in water for many hours. This slow cooking process releases many nutrients into the broth, including minerals, amino acids, healthy fats, and electrolytes.
Possible benefits of bone broth include:
- Improved digestive health
- Stronger bones
- Hydration and electrolyte balance
- Weight management support
