After water, Collagen is the most abundant protein in your body and makes up several body parts, including tendons, ligaments, skin and muscles. It makes up 80% of your skin's structure which maintains skin elasticity and helps to strengthen the skin and provide hydration. As you age, your body produces less collagen, leading to joint pain and stiffness, hair loss or thinning, skin ageing and wrinkles and a decrease in the elasticity of ligaments and tendons. Other well-known benefits include stronger hair and nails, gut health, brain health, joint support and some research even mentions weight loss.

Types of Collagen

There are five types of collagen throughout the body and they all have different functions.

Type I: This type is the most abundant collagen in the body, used to form our skin, bones, tendons, blood vessel walls and other connective tissues.   

Type II: This collagen type is found mostly in cartilage and vitreous humour (tissue in the eyeball). It's also a structural component of the ear, the nose, the bronchial tubes, the rib cage and more.

Type III: This collagen type is found largely in blood vessels, intestines, muscles, skin, hair, nails, teeth, eyes, muscles and more. Like type l, it contributes to tissue elasticity and often in supplements designed to support healthy skin.

Type V: Type V collagen contributes to the formation of bone matrix, cornea of the eye, muscle fibres, liver, lungs and the placenta. Type V collagen also helps to form cell surfaces, maintain healthy hair and it co-exists with type II collagen in joint cartilage.

Type X: This collagen plays a crucial role in bone formation.

We Come Highly Recommended

Collagen theory is the only Collagen product that contains green tea, grape seed and aloe vera which is great for my skin and my weight loss goals. I noticed a more radiant glow to my skin after just 2 weeks! Highly recommended!


Collagen theory’s products are now part of my beauty/fitness ritual and it is a less invasive and less expensive alternative to expensive Collagen fillers that do not last! I use a combination of Collagen theory quality products to achieve and maintain my beauty and fitness goals. The results are amazing!


I have been using Collagen for just over a year now before a friend recommended Collagen theory’s products. I find that is far more superior than all the other products I have tried in terms of overall skin and health benefits. I am happy to join the Collagen Theory Family.


I got Collagen theory SYNERGY for my gran after trying their product myself and seeing great results. She is very pleased and tells me it helped her Joint aches. I don’t suffer with joint aches myself, but I do get bloated and I feel this has helped as well as great skin, hair and nails. They are also fairly priced.


Collagen Theory is my go-to for post workout clean protein supplement. I like that it is all natural, and even the liquid is sugar free. I feel fuller in the mornings when I supplement my porridge with Collagen Theory.
