Collagen

Compare every Collagen product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.

Structural protein supporting joints, skin, and connective tissue

We rank Collagen by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.

What it is

Collagen is a structural protein, which is a large molecule that acts as a building block for the body. It provides the essential framework and strength for your skin, joints, and connective tissues.

Why it's used

It is primarily taken to support the health and integrity of the body's structural systems. People use it to help maintain the elasticity of their skin and the cushioning in their joints.

How it's made

Commercial collagen is produced by extracting the protein from animal sources, such as bovine cows or marine fish. The raw materials are processed using heat and enzymes to break the large proteins down into smaller pieces that the body can absorb more easily.

What it typically costs

This ingredient is generally mid-range in price. This is because the process of extracting and refining the protein from animal tissues is more involved than producing simple synthetic vitamins, but there is a very large global supply of raw materials.
