About Collagen


What’s collagen?

Collagen is the most abundant protein in the human body. It is regarded as the substance that holds the whole body together and can be found in the bones, muscles, skin and connective tissues like joints & tendons.[1]

 

Why is collagen important?

Collagen is the protein that keeps much of your body supple and healthy. It plays important structural roles and contributes to mechanical properties, organization, and shape of tissues. It is vital to the skin, bones, joints, hair, and nails, among others.

Collagen is the main component of human skin (80%) and is in the middle layer of the skin – the dermis – collagen gives skin structural support, rmness and elasticity and helps form a brous network, upon which new cells can grow.

It is in fact even extensively used in plastic surgery as a filler to rejuvenate skin in the form of collagen injections.

Why should we take collagen supplements?

Although the body consistently produces collagen until around the age of 40, collagen production begin to decline at around age 25, at the rate of about 1.5% per year.[2]  That means that by the age of 45, levels would have reduced by as much as 30% in your body.

This intrinsic ageing process may be accelerated by photo-ageing from sun exposure, lifestyle patterns of alcohol consumption, smoking, high stress and high sugar consumption lifestyle.

As collagen diminishes, formation of wrinkles, the appearance of brown spots, loss of skin firmness and skin thickening appears and visibly increases with time.  Gravity makes it worse by pulling the loosen skin causing sagging eyelids; eye bags to appear giving an aged appearance.

One effective strategy to managing the natural process of skin ageing is to adopt a healthy outlook in life, have balance work life patterns and maintain a balanced diet and a good supply of food supplements.[3]
