What are the True Benefits of Collagen Supplements?

Collagen supplements  have become a popular topic in the wellness community and for good reason. They are said to offer a range of health benefits, from improving skin health to supporting joint function. But what does the science say, and how can you incorporate them into your lifestyle? Let’s dive into the world of collagen and discover its true benefits.

Understanding Collagen

Collagen is the most abundant protein in our bodies, especially type 1 collagen. It’s found in muscles, bones, skin, blood vessels, the digestive system, and tendons. It’s what helps give our skin strength and elasticity, along with replacing dead skin cells. When it comes to our joints and tendons, in simplest terms, it’s the “glue” that helps hold the body together.

The Role of Collagen in the Body

Our body’s collagen production naturally begins to slow down as we age. We can see this in the form of signs of aging, such as wrinkles, sagging skin, and joint pain due to weaker or decreased cartilage. Other lifestyle factors — like eating a diet high in sugar, smoking, and high amounts of sun exposure — can also contribute to depleting collagen levels. It’s interesting to note that collagen-related diseases most commonly arise from a combination of genetic defects, poor intake of collagen-rich foods, or nutritional deficiencies that affect the production of collagen.

How to Naturally Produce Collagen

Our bodies produce collagen by combining amino acids — nutrients you get from eating protein-rich foods, like beef, chicken, fish, beans, eggs, and dairy products. The process also requires vitamin C, zinc, and copper. You can get vitamin C by eating citrus fruits, red and green peppers, tomatoes, broccoli, and greens. For zinc, add foods like beef, lamb, pork, shellfish, chickpeas, lentils, beans, milk, cheese, and various nuts and seeds to your diet. Copper can be found in organ meats, cocoa powder, cashews, sesame seeds, and lentils.

Collagen Supplements: What Are They?

Collagen supplements are typically sold as collagen peptides or hydrolyzed collagen, which are forms of collagen that are more easily absorbed by our bodies. These supplements can be derived from various sources, including bovine (cow), porcine (pig), chicken, and marine (fish) collagen. Vegan options are also available, which are made from genetically modified yeast and bacteria.

Benefits of Collagen Supplements

Improve Skin Health

Collagen plays a crucial role in skin repair and regeneration, which is why it’s often associated with youthful skin which helps improve skin hydration and elasticity. As we age, our body’s natural collagen production declines, leading to visible signs of aging such as wrinkles and sagging skin. Collagen supplements have been shown to help:

  • Boost skin hydration: By increasing the skin’s water content, collagen supplements can lead to plumper, less dry skin.
  • Enhance skin elasticity: Improved elasticity means more resilient skin, which can reduce the appearance of fine lines and wrinkles.
  • Support skin repair: Collagen can aid in the healing process of the skin, helping to repair damaged skin and maintain a healthy complexion.

Helps Improve Joint Health:

Collagen is a major component of cartilage, the tissue that protects your joints. With age, the amount of collagen decreases, leading to joint issues such as stiffness and pain. Collagen supplements can:

  • Ease joint pain: Regular intake of collagen may reduce pain associated with joint degeneration and improve quality of life.
  • Maintain joint flexibility: Collagen helps to maintain the integrity of cartilage, which is essential for smooth joint movement.
  • Support joint repair: Collagen supplementation may contribute to the regeneration of joint tissue and help manage conditions like osteoarthritis.

Strengthen Bones and Muscles

Collagen is essential for maintaining the integrity of our bones and muscles. It helps to:

  • Maintain bone density: Collagen contributes to the density and strength of bones, which can prevent conditions like osteoporosis.
  • Support muscle tissue: Collagen is involved in maintaining muscle mass and function, which is particularly important as we age to prevent sarcopenia, a loss of muscle mass.

Improve Heart Health

The role of collagen in cardiovascular health is significant. It helps to:

  • Provide structure to arteries: Collagen fibers provide elasticity and strength to blood vessels, supporting healthy circulation.
  • Maintain heart muscle: Adequate collagen levels are necessary for maintaining the structural integrity of the heart muscle.

Hair and Nail Growth

Collagen’s impact on hair and nail health includes:

  • Strengthening hair: Collagen may support hair follicle health and could contribute to hair strength and growth.
  • Improving nail growth: Collagen can improve nail strength, reducing brittleness and promoting faster growth.

Support Digestive Health

Collagen’s benefits for digestive health are due to its role in:

  • Maintaining the gut lining: Collagen helps in the repair and regeneration of the intestinal lining, which is crucial for overall digestive health.
  • Promoting digestion: Collagen can aid in the smooth movement of food through the GI tract, thus supporting proper digestion.

Bone Broth: A Natural Source of Collagen

Bone broth is made by simmering the bones and connective tissue of animals. This nutrient-dense, flavorful liquid is rich in amino acids and is an excellent source of natural collagen. Bone broth can be a part of a balanced diet and is a comforting way to support collagen production in the body.

Randomized Controlled Trials

The gold standard for testing the effectiveness of supplements is through randomized controlled trials. These studies have provided evidence that oral collagen supplements can have beneficial effects on skin health and joint pain.

Side Effects

While collagen supplements are generally safe, they can cause digestive side effects, such as feelings of fullness and heartburn. It’s also important to note that supplements are not regulated by the Food and Drug Administration (FDA) in the same way that food and drugs are, so it’s crucial to purchase them from reputable sources.

How Much Collagen Should You Take?

The amount of collagen you should take daily depends on the reason for using it. For general health, doses between 2.5 to 15 grams of collagen daily have been used in studies and are generally considered safe.


Collagen supplements can be a beneficial addition to a balanced diet, especially for those looking to improve skin health, hydration, and elasticity, as well as support joint and bone health. However, it’s important to approach them as a complement to a healthy lifestyle, not a substitute for a varied diet.

Remember, the key to reaping the benefits of collagen supplements is consistency and choosing a product that fits your specific needs and health goals. Whether you opt for powders, capsules, or bone broth, incorporating collagen into your daily routine could be a step towards a healthier, more vibrant you.
