What you should know before you start using collagen

Collagen has become one of the most talked-about supplements in the UK wellness space and with good reason. As the body’s most abundant protein, collagen provides structure and strength to the skin, hair, nails, joints, and connective tissues. However, collagen production naturally slows down over time, typically from the mid-20s onwards. This gradual decline is part of the natural ageing process.

With this in mind, many people include collagen supplements in their daily routines to provide the body with amino acids that serve as building blocks for collagen formation.

What is collagen?

Collagen is a structural protein naturally produced by the body. It acts as a framework that helps maintain tissue integrity and elasticity. Over time, the body’s ability to produce collagen decreases. This is why collagen supplements are often formulated to supply amino acids.

How does collagen work in the body?

When taken orally, collagen peptides are broken down into amino acids and small peptides. These nutrients are then available for use wherever the body needs them, including in connective tissues and skin.

Consistency is key: using collagen daily over a longer period may help maintain normal protein metabolism and overall tissue structure.

What type of collagen is found in supplements?

There are several types of collagen found in the body, but the most common ones used in supplements are types I, II, and III:

Type I – Found in skin, hair, nails, and bones

Type II – Present mainly in cartilage and joints

Type III – Supports connective tissues and works alongside Type I

Different formulations may contain marine, bovine, or chicken-derived collagen sources. Choosing between them depends on personal preferences, diet, and lifestyle.

How can collagen be taken?

Collagen supplements come in several convenient formats, such as powders, capsules, and ready-to-drink liquids:

Powders can be mixed into smoothies, coffee, or water.

Capsules are easy to take when travelling or on the go.

Liquid collagen provides a simple way to include it in your daily routine.

Regardless of the form, taking collagen consistently is what matters most. Combining collagen with vitamin C, which contributes to normal collagen formation for the normal function of skin, cartilage and bones, can further support the body’s natural processes.*

What to consider when choosing a collagen supplement

Look for products that clearly state their collagen source and type.

Choose hydrolysed collagen (collagen peptides) for easier absorption.

Consider formulas that also include vitamin C for added support.

Opt for a trusted brand that provides transparency and quality assurance.

Collagen is more than a passing wellness trend. It’s a key structural component of the human body.
Understanding what collagen is, how it functions, and how to include it in your daily routine can help you make informed choices for your overall wellbeing.
