The difference between collagen and silica

The big difference? Collagen provides the readily available base for an instant collagen 'top up' while silica helps to make collagen so will take longer for any noticeable effect.

Connective tissue

Connective tissue can be found in many different areas of your body, other than your hair, skin and nails, including:

  • Cartilage to protect bones from rubbing against each other in your joints
  • Ligaments that connect bones to bones at joints
  • Tendons that attach and anchor muscles to a bone
  • Bone that provides a strong structural framework for your body
  • Teeth that allow you to chew and breakdown foods for healthy digestion


Collagen provides tensile strength, firmness and stability to connective tissue and is the most abundant protein found in your body, making up around 30% of your total body protein. Collagen fibres are made up of three different amino acid building blocks or proteins that intertwine together, much like a strongly braided rope. Collagen holds you together by ‘supporting and connecting’ different structures in your body, giving you ‘architectural strength’, like bricks and mortar in a building.

There are over 20 types of collagen in your body, although type I collagen makes up around 90% of the collagen found in your body. Marine collagen provides type I collagen which has greater absorption and bioavailability due to its low molecular weight or smaller particles, when compared to bovine, porcine or poultry sources of animal based collagen.

As you begin to ‘mature’ and age, you may start to notice a number of unwelcome changes occurring in your body. Collagen levels, particularly type I collagen, naturally begin to decline as you age, resulting in visible signs of ageing and problems with weak, painful and stiff joints. 


Your body contains around 7g of silica, concentrated mainly in your skin, bones, hair, tendons and blood vessels. When you’re young, you naturally have higher levels of collagen and silica, and this is reflected in your firm, wrinkle-free skin and flexible pain-free joints. Silica is required for the production of collagen, and as you age, both your collagen and silica levels begin to decline. A silica deficiency creates problems in producing and maintaining healthy collagen levels.  

To help maintain healthy connective tissue right now, take collagen for an instant ‘top up’ to replenish lost or declining levels of collagen to help slow down the visible signs of ageing and to help stabilise and strengthen your joints.
