Frequently asked questions about collagen

Frequently Asked Questions about Collagen

Collagen is generally described as the “glue that keeps the body together”.

Collagen is tissue fibres with high tensile strength due to their unique triple helix structure and the cross-linking between the fibrils.

Collagen is the most abundant protein in the human body. Collagen is a specialised protein, 25-30% of the protein in the body consists of collagen.

Collagen has many functions in the body but could be described as giving structure to the tissue in the body, keeping the body intact and functional.

75% of the skin consists of collagen. Collagen keeps the skin, firm, elastic, hydrated and smooth.

90% of organic bone consists of collagen. Collagen acts as the structure of the bone for minerals to bind upon. Collagen gives the bone strength and flexibility.

85% of Tendons consist of collage. Collagen gives connective tissue its strength and elasticity.

70% of Cartilage, (Type I Fibro-cartilage and Type II elastic and hyaline cartilage). Mostly elastic and hyaline collagen for healthy cartilage.

70% of Ligaments – Connective Tissue consists of collagen for strength and flexibility.

Collagen is derived from animal tissue. all animals have collagen to keep their body structure and form.

Commercial collage is primarily sourced from cowhide and is called “bovine-derived collagen”.

The second most common source of commercially sold collagen is fish, also known as “marine collagen” but contrary to the term “marine” which implies sea fish, most fish collagens are derived from freshwater fish like tilapia, using the skin or in some cases the scales or both.

The third source is derived from pigs called “porcine-derived collagen”. Porcine collagen is only sold in certain countries; not many health and fitness collagen supplements contain porcine.

Another source of commercial collagen is derived from chicken cartilage. This is mainly collagen Type II and is predominantly used in small quantities as denatured Type II Collage sold in the joint health market.

All of these collagens are sourced as native intact collagen and have to be hydrolysed and enzymatically pre-digested before they could be used as edible collagen for humans.

Hydrolysed collagen is called “collagen peptides” and is only bioavailable in this form.


Collagen consists of amino acids bound together to form a triple helix of elongated fibril known as a collagen helix. The collagen fibres are made of coiled, stacked ropes of protein. The structure is a triple helix, of protein strands bundled into microfibrils that are packed and connected together in strong, long collagen fibres.

Collagen peptides are small collagen molecules created through hydrolysis. The hydrolysed collagen strands are then further digested by using an enzymatic process resulting in collagen peptides.

The peptides are amino acid structures bonded in a specific sequence and are the building block of collagen fibrils.

Mono-, di- and tripeptides are formed by the process. The tripeptides and dipeptides are the most significant.


Hydrolysis occurs when the native collagen is treated with water and heat to denature the collagen into individual collagen strands. These stands are not bioavailable and have to be broken down into smaller pieces to be bioavailable.

A specific enzyme is used to target specific amino acid bonds. The enzyme cleaves the bond to form the smaller peptide particles.

Bioavailability refers to the intrinsic properties of a substance essential to pass through the gastrointestinal tract and be delivered intact to the target tissue site.

 Your Skin

The most noticeable will be the loss of the firmness and elasticity of the skin. Fine lines and wrinkles will start to appear due to contributing factors such as exposure to UV, pollution, and lifestyle choices.

Collagen provides the structure in the skin, elastin binds to the collagen to give your skin natural elasticity, it creates the environment for hyaluronic acid to bind to the collagen fibres and provides the skin with moisture.

By losing collagen the skin losses structure, firmness, elasticity and moisture.

                Your Bones

Less noticeable signs will be the loss of bone density and the natural flexibility of the bones. Most of the time you will incur a fracture before you are aware of the problem.

Collagen is the structure of all the bone in your body. It provides a flexible framework for organic minerals like Calcium to bind to. The combination of collagen and minerals ensure strong, dense and flexible bones to reduce the chances of fractures.

By losing collagen the bones become weak and brittle, increasing the risk of osteoporosis and fractures.

                Your Joints

The demands of day to day life causes wear and tear on joints cartilage. This impairs the joints and causes restricted mobility and inhibit normal movement.

Damage to the cartilage and joints causes pain and discomfort. You become less active and lose even more muscle and connective tissue.

                Your Muscle and Connective Tissue

Your muscles and connective tissue (ligaments and tendons) makes up the unit that keeps all your bones in place, it provides movement, stability and balance.

85% of tendons and 70% of ligaments consists of collagen.

The loss of collagen has a dramatic impact on body posture, overall muscle strength, mobility and balance. This will increase the risk of injury, fractures and pain due to poor posture and balance and mobility.

Yes! Most definitely!

It is never too late to start using collagen powder.

Your body will always be able to use collagen peptides to repair and replenish your body.

We have customers in their 90s still using the SONTAL Collagen daily.

In simple terms, collagen peptides consist of proteins familiar to the body. Your body produces the same collagen endogenously.

It is not necessary to take collagen earlier than the age of 25, until then your body produces its own collagen, and your collagen stores should be normal.

Collagen peptides are not a medicine but rather a functional food.

You may use collagen peptides from a younger age under special circumstances, you might be an athlete who wants to reduce the risk of injury or you might be recovering from an injury or surgery.

You can also ask your doctor or healthcare professional for advice if you feel you may benefit from collagen peptide supplementation.

Results will start soon after but you might only notice visible results between 8 and 12 weeks.

 Keep in mind;

  1. Collagen peptides are not medicine.
  2. Collagen powder consists of unique amino-acid structures called peptides. It is a protein, recognised by the body to be unique and the same as the endogenous collagen produced by your own body.
  3. Your body will use the collagen peptides as needed and determined by your body’s metabolic pathways. It can’t be forced.
  4. Your results will be unique to your body but will surely benefit you in many ways.
  5. Your health, diet, age, gender and medication will also play a determining role.

Studies show Peptan peptide absorption within 24 h.

Results will start soon after but you might only notice visible results between 8 and 12 weeks.

You might experience the results you expected but you will also receive all the benefits of taking collagen powder supplementation.
