Collagen: What It Is, Types, Functions, and Benefits

What is Collagen?

Collagen is a protein that forms the foundation of your skin, muscles, bones, tendons, ligaments, and connective tissues. It’s made up of amino acids like glycine, proline, and hydroxyproline. Different types of collagen perform various functions in the body. However, as we age, collagen levels naturally decline, which is why collagen supplements are often recommended.

Types of Collagen

Here are the five main types of collagen and their functions:

Type 1: The most common, making up 90% of your body’s collagen. It provides strength and structure to bones, skin, tendons, and ligaments.

Type 2: Found in cartilage, it supports joint health.

Type 3: Helps build muscles, arteries, and organ tissues.

Type 4: Found in skin layers, it supports healthy skin.

Type 5: Present in the placenta, cornea, and certain skin layers.

Collagen-Rich Foods

Add these foods to your diet to boost collagen:

• Bone broth
• Chicken
• Egg whites
• Fish
• Tomatoes
• Berries
• Broccoli
• Whole grains

Signs of Collagen Deficiency

• Fine lines and wrinkles
• Joint pain
• Hair loss and brittle nails
• Muscle soreness
• Decreased bone density
• Low blood pressure
• Digestive issues (like leaky gut)

Causes of Collagen Deficiency

• Inactivity
• Stress
• Alcohol consumption
• Smoking
• Excessive sun exposure

Benefits of Collagen

• Improves Skin Hydration: Boosts skin moisture and elasticity.
• Reduces Wrinkles: Helps smooth wrinkles and enhances skin texture.
• Enhances Skin Elasticity: Restores firmness and prevents sagging.
• Eases Joint Pain: Reduces inflammation and improves cartilage health.
• Prevents Bone Loss: Maintains bone density and reduces the risk of fractures.

How to Boost Collagen Levels

While collagen-rich foods help, it’s hard to get enough through diet alone. Collagen supplements are a convenient option.

Marine collagen, especially Japanese marine collagen peptides, is highly absorbable and effective for skin health. Starting collagen supplements early can help combat wrinkles, sagging, and joint issues over time.

Conclusion

Collagen is essential for maintaining healthy skin, hair, nails, and joints. Since most collagen comes from animal sources, vegetarians and vegans might find it harder to get enough through food alone. That’s where supplements, particularly marine collagen, can play a key role in promoting overall health and youthful skin.
