UNDERSTANDING THE COLLAGEN JOURNEY
How Is COLLAGEN Absorbed?
Many people take collagen supplements to support their skin, hair, nails, joints, and overall wellbeing. But what actually happens after you consume collagen?
From digestion in the gut to distribution throughout the body, collagen undergoes a fascinating journey before its amino acids and peptides can be used by the body's tissues. Understanding this process can help explain why consistent collagen supplementation is often recommended.
In this guide, we'll explore exactly how collagen is absorbed and utilised by the body, step by step.

What Is Collagen? The Ultimate Guide to the Body’s Most Essential Protein
Collagen is the most abundant protein in the human body, making up nearly 30% of our total protein content. It’s the structural backbone of our skin, bones, muscles, tendons, ligaments, cartilage, and even blood vessels. Often described as the “glue” that holds the body together, collagen plays a vital role in maintaining strength, elasticity, and regeneration throughout the body.
In this complete guide, we’ll break down:
- What collagen is
- The different types of collagen
- How your body makes collagen
- Why collagen levels decline with age
- The benefits of collagen supplements
- Scientific research supporting collagen use
🔬
What Exactly Is Collagen?
Collagen is a fibrous, structural protein made of long chains of amino acids, primarily:
- Glycine
- Proline
- Hydroxyproline
- Arginine
These amino acids form triple helices that bundle into strong collagen fibrils—key components of connective tissue.
It’s found in:
- SKIN: providing firmness and elasticity
- BONES & JOINTS: giving structure and shock absorption
- MUSCLES: supporting strength and recovery
- HAIR & NAILS: aiding growth and resilience
- GUMS & TEETH: maintaining oral health
In fact, this wonder protein makes up around 70% of the dry mass of our skin and forms the extracellular matrix (the mesh network that keeps our skin resilient and bouncy).
THE COLLAGEN ABSORPTION JOURNEY
step 1
Collagen Enters the Digestive System
When you consume collagen, whether as a liquid, powder, capsule, or gummy, it first enters the stomach. Most supplements contain hydrolysed collagen peptides, which have already been broken down into smaller peptide chains. This process makes collagen easier to digest and incorporate into everyday nutrition. Digestive enzymes and stomach acids begin breaking collagen down further into smaller peptides and amino acids.
Step 2
Collagen Is Broken Down Into Amino Acids
Inside the small intestine, collagen peptides are further digested into individual amino acids and short-chain bioactive peptides.
Some of the key amino acids found in collagen include:
Glycine
Proline
Hydroxyproline
Arginine
Alanine
These amino acids are the building blocks the body uses to support a variety of tissues and biological processes.
Step 3
Absorption Through the Intestinal Wall
The resulting amino acids and collagen peptides pass through the intestinal lining and enter the bloodstream.Research suggests that certain collagen-derived peptides may be absorbed intact rather than being completely broken down into individual amino acids.Once absorbed, these nutrients become available for use throughout the body.
step 4
Transport Around the Body
After entering the bloodstream, collagen-derived amino acids and peptides circulate throughout the body.
Rather than travelling directly to a specific area such as the skin, they are distributed wherever the body requires them.
These building blocks may contribute to the maintenance and renewal of:
Skin | Hair | Nails
Bones | Cartilage
Tendons | Ligaments
Muscles
Blood vessels
Step 5
Supporting Natural Collagen Production
The body continuously produces, repairs, and replaces collagen-rich tissues.The amino acids supplied through diet and supplementation can be used as part of these natural processes.Vitamin C plays an especially important role because it contributes to normal collagen formation for the normal function of skin, bones, cartilage, gums, teeth, and blood vessels.This is why many collagen products include vitamin C or are recommended alongside a vitamin C-rich diet.
step 6
Supporting Skin Structure and Appearance
One reason collagen supplements have become so popular is their association with skin health.
Collagen is a major structural protein within the skin and helps support:
✨ Skin firmness
✨ Skin elasticity
✨ Skin hydration
✨ Overall skin appearance
As natural collagen production declines with age, many people choose collagen supplementation as part of their beauty and wellness routine.
step 7
Supporting Joints and Connective Tissues
Collagen is also found throughout the body's connective tissues.
These include:
🦵 Cartilage
🏃 Tendons
💪 Ligaments
🦴 Bones
Because of collagen's role in these structures, collagen supplementation is commonly used by active individuals, athletes, and those seeking to maintain mobility as they age.
Why Does Hydrolysed Collagen Matter?
Most modern collagen supplements use hydrolysed collagen peptides.
Hydrolysis breaks collagen into smaller peptides that:
✅ Mix easily into liquids
✅ Digest more efficiently
✅ Are convenient to consume daily
This makes hydrolysed collagen one of the most popular forms of collagen available today.

What Happens When Collagen Declines?
Collagen loss is a natural part of ageing. By the time you reach 40, you may lose up to 1% of collagen each year. This leads to:
- Wrinkles and sagging skin
- Joint discomfort
- Loss of muscle mass
- Thinner hair and brittle nails
- Delayed wound healing
This is why many turn to collagen supplements to support natural levels.
Factors That Influence Collagen Absorption
Several factors may influence how effectively the body utilises collagen:
🍊 Adequate vitamin C intake
🥩 Sufficient dietary protein
💧 Good hydration
😴 Quality sleep
🏃 Regular physical activity
🚭 Avoiding smoking
☀️ Limiting excessive UV exposure
A balanced lifestyle helps support the body's natural collagen-producing processes.

Why Choose Marine Collagen?
Marine collagen, sourced from wild-caught fish skin and scales, is:
- More bioavailable than bovine collagen (up to 1.5x better absorption)
- Naturally rich in Type I collagen
- Sustainable and eco-friendly
- Suitable for pescatarians
Essentia Natura uses premium marine collagen peptides combined with Vitamin C, Hyaluronic Acid, Biotin, and Zinc for enhanced results.
Peptan® collagen increases skin hydration but 28% after 8 weeks! Plus in those women the skin hydration level increased a phenomenal 91% after 8 weeks as well.

When & How to Take Collagen
Best Time: Morning on an empty stomach or post-workout
Form: Liquid (like Essentia Natura), powder, or capsules
Dosage: 5–10g per day is typically effective
Support Nutrients: Take with Vitamin C to enhance absorption
