Collagen is a vital protein found naturally in the human body, contributing to the structure of skin, bones, and cartilage. Unfortunately, as we age, collagen production begins to decline, leading to various health and aesthetic issues. To combat this, many individuals turn to collagen supplements, which are typically derived from hydrolyzed collagen peptides sourced from animals. These supplements may come in pill, liquid, or powder forms and are believed to promote health benefits for skin, nails, joints, muscles, and bones.
1. May Improve Skin Health
Research indicates that collagen supplementation can enhance skin elasticity and hydration. Studies have shown that taking collagen for a period of four to 24 weeks can reduce wrinkles and improve overall skin texture. Supplements may even promote the production of elastin, a protein crucial for skin resilience.
2. May Relieve Joint Pain
Collagen has been studied for its potential to ease joint pain and other arthritis symptoms. Regular intake of collagen supplements can stimulate collagen synthesis in cartilage, which may slow the progression of osteoarthritis—a degenerative condition that affects joint health.
3. May Prevent Bone Loss
Collagen supplements may play a role in combating osteoporosis, a condition characterized by decreased bone mass and density. Though most studies have involved high-risk groups like postmenopausal women, they suggest that collagen could alleviate symptoms such as stiffness and pain in affected individuals.
4. May Increase Muscle Mass
Collagen may also support the synthesis of important muscle proteins, like creatine, which can enhance muscle mass. In one study, male participants who supplemented with collagen reported significant gains in muscle mass and strength, particularly when combined with resistance training.
5. May Promote Heart Health
Collagen supports the structural integrity of arteries, minimizing the risk of cardiovascular issues by preventing weakness or narrowing. Some studies have found that collagen supplementation can improve levels of beneficial HDL cholesterol and enhance arterial flexibility.
6. May Improve Gut Health
Collagen’s amino acids, such as glycine and glutamine, can fortify the lining of the digestive tract. Collagen supplements may act as a protective barrier against harmful bacteria, potentially alleviating symptoms such as bloating in adults.
7. May Strengthen Hair and Nails
The amino acids found in collagen, particularly keratin, are essential for maintaining healthy hair and nails. Preliminary studies suggest that collagen supplementation can reduce hair breakage and improve the overall quality of nails.
8. May Help Support Weight Loss
Though research is still emerging, collagen supplementation may help enhance feelings of fullness, potentially aiding in weight loss. One study indicated that taking marine collagen daily for 12 weeks could lead to reductions in body fat percentage.
A Word From Verywell
Collagen is produced naturally in the body through a diet rich in protein and nutrient-dense foods such as nuts, broccoli, and whole grains. Lifestyle choices such as avoiding alcohol, smoking, and excessive sun exposure can also help maintain collagen levels.

Are There Downsides to Taking Collagen Supplements?
While collagen supplements are generally safe for most adults when taken in moderation, some common side effects can occur. Individuals allergic to shellfish should exercise caution, as some collagen products are derived from marine sources.
Collagen-Rich Foods
To naturally increase collagen levels, incorporate the following foods into your diet:
- Beef: Especially from bovine hide and bones
- Bone Broth: A rich source of collagen from animal bones
- Chicken: Particularly chicken cartilage
- Fish: Known for providing marine collagen
- Pork Rinds: Made from pigskin
Additionally, consume foods abundant in amino acids essential for collagen production, such as eggs, dairy, legumes, and soy.
How Much Collagen Do You Need?
There are no federal guidelines for collagen supplementation; however, research generally supports a daily intake of 2.5 to 15 grams for optimal benefits, especially for skin health. Always consult a healthcare provider before starting any new supplement to ensure it’s appropriate for your needs.
Summary
Collagen is an essential protein supporting various body functions, including skin, joints, and bones. While collagen production naturally declines with age, supplementation may offer multiple health benefits. Available in various formats, it’s essential to understand the potential advantages and consult with a healthcare professional before integrating collagen into your routine.
