What is Collagen and Why is it So Important?

Collagen is the most abundant protein in the human body and makes up about 30% of our total protein content. It is the most important building block for skin, bones, tendons, ligaments and connective tissue.

The name "Collagen" comes from the Greek word "kólla", meaning "glue" – because collagen literally holds our body together. It forms a stable structure that gives our skin firmness and elasticity.

From the age of 25, our body's own collagen production begins to decline – by about 1-1.5% per year.

The good news: By taking hydrolyzed collagen (collagen peptides), we can support our body's collagen production.

The small peptides are easily absorbed by the body and can work where they're needed.

Collagen has a unique amino acid composition – particularly rich in glycine, proline and hydroxyproline, which are essential for forming new collagen fibers.

Collagen Effects on Skin: Fewer Wrinkles, More Elasticity

The skin is the body's largest organ and consists of about 75-80% collagen. It provides structure, firmness and elasticity to your skin. As we age, the body's collagen production decreases, leading to:

  • Fine lines and deeper wrinkles
  • Loss of skin elasticity and firmness
  • Drier, thinner skin
  • Slower wound healing

Regular intake of hydrolyzed collagen can improve skin moisture, increase elasticity and reduce fine lines. The small collagen peptides travel through the bloodstream directly to the skin layers and stimulate the body's own collagen production.

Recommended daily dose for visible skin improvements: 15g collagen daily. With Rosavie Collagen Powder, you can reach this dose with just one scoop.

Collagen for Healthy Joints and Cartilage

Joints are complex structures that connect bones and enable movement. Collagen (especially Type II) is the main component of joint cartilage – the smooth layer covering bone ends that acts as a shock absorber.

With increasing age or heavy strain (sports, physical work), cartilage can wear down. The result: stiffness, pain and limited mobility. Taking collagen supports:

  • Regeneration of cartilage tissue
  • Flexibility and mobility of joints
  • Reduction of joint discomfort during activity
  • Strengthening of tendons and ligaments

Athletes and people with active lifestyles particularly benefit from regular collagen intake to support joint health.

Stronger Hair and Nails Through Collagen

Hair and nails mainly consist of keratin, a protein similar in structure to collagen. The amino acids from hydrolyzed collagen – especially proline and glycine – are essential building blocks for keratin production.

Regular collagen intake can bring the following improvements:

  • Hair: More volume, shine and strength, less breakage and split ends
  • Nails: Stronger, less brittle nails, faster growth
  • Scalp: Better blood circulation and nutrient supply to hair follicles

First visible improvements in hair and nails typically appear after 8-12 weeks of regular intake.

What Collagen Types Exist?

In the human body, 28 different collagen types have been identified so far. The most important ones for beauty and health are:

Type I – The Beauty Type (90% of body collagen)

Found in skin, bones, tendons, ligaments and teeth. Optimal for anti-aging and skin health.

Type II – The Joint Specialist

Main component of joint cartilage. Ideal for joint health and mobility.

Type III – The Partner of Type I

Works together with Type I in skin, blood vessels and internal organs. Supports skin elasticity and wound healing.

Rosavie Tip: Our collagen products contain hydrolyzed collagen Types I and III – the optimal combination for skin, hair and nails.

When Does Collagen Start Working?

One of the most common questions is: "When will I see results?" The answer depends on various factors – your age, diet and how consistently you take collagen.

The good news: Most people notice first positive changes after 4-6 weeks. For optimal results, we recommend taking collagen for at least 3 months.

Important: Collagen is not a miracle cure that works overnight. It's an investment in your long-term health and beauty. The earlier you start, the better!
