Discover what collagen can do for you.


Of all the supplements in our range, collagen and silica are quickly gaining popularity thanks to new studies and research about their health benefits.


You’ll find collagen products suited to your needs across our site, with collagen tablets, collagen capsules and collagen powder, which simply stirs into your drink.


Silica is more common in its capsule form, but just like our collagen range, we stock silica products in various sizes for you to stock your supplements cupboard with.


But what are the benefits of collagen and silica? What is collagen used for, and why is it being recommended by health experts alongside silica? Let’s start with collagen.


What is collagen?


It’s easiest to think of collagen as the building blocks of the body. Categorised as a structural protein, it connects tendons, ligaments and muscles and gives your skin its elasticity and structure – it’s also the basis of strong and healthy bones.


What is collagen made of?


Specific amino acids like glycine, proline hydroxyproline and arginine all feature in collagen. You’ll find many of these in supplement form and in a variety of high protein foods, including bone broth.


In addition, collagen is also the most common protein in the body, where it’s naturally produced. So why would you ever need collagen supplements?


For starters, your body begins to slow its collagen production after you reach 25. Another reason to explore collagen supplements is that smoking, ultraviolet light from the sun and consuming excessive sugar can decrease your collagen levels.


What are the benefits of collagen?


Collagen’s perceived benefits have been written about extensively.


Here are just a few of the most common benefits written under review:


  • Bone health – collagen contributes to normal function of bones
  • Skin and nail health – collagen contributes to maintanence of normal skin and nails
  • Joint health – collagen helps maintainence of cartilage in the body which is integral to good joints


What is silica?


If collagen is in all of us, silica is found everywhere else. A natural compound, it makes up over a quarter of the Earth’s crust and is found in rocks, sand and even some foods. Like collagen, silica has many different perceived benefits. These include the following:


  • Bone formation and maintenance – silica may help to improve your bone health, with a deficiency in silica believed to be partly linked to cartilage deterioration
  • Collagen production – some studies show silica can help your body’s production of collagen, which you’ve already read is linked to a number of skin and bone benefits


Foods that contain silica


The list of foods that contain silica includes but isn’t limited to:

  • Wholegrains
  • Green beans
  • Rice
  • Cucumbers
  • Tomatoes

Similar to collagen, silica can be found in supplement form, with a range of silica capsules and tablets available on our website from leading supplement brands.


Silica supplements are an excellent choice if your diet contains few of the above foods, or simply if you’re looking for supplements to add to your cabinet.
