Collagen supplements have become increasingly popular in recent years — but what exactly is collagen, and how do you choose the right product?

If you’re considering adding collagen to your routine, here’s a practical guide to understanding what it is, how it’s used in the body, and what to look for when selecting a supplement.

What Is Collagen?

Collagen is a structural protein naturally found in the body. It is a key component of connective tissues, including skin, cartilage, bones, and tendons. As we age, natural collagen production gradually declines.

Collagen supplements are designed to provide specific amino acids that are also found in the body’s own collagen.

Types of Collagen in Supplements

There are several types of collagen, but most supplements focus on:

• Type I & III – Commonly found in skin, bone and connective tissue

• Type II – Found in cartilage

Most over-the-counter collagen products contain hydrolysed collagen peptides (also called collagen hydrolysate). This means the protein has been broken down into smaller peptides for easier mixing and digestion.

Common Sources of Collagen

Collagen supplements are typically derived from:

• Bovine (cow) collagen

• Marine (fish) collagen

• Porcine (pig) collagen

If you have dietary preferences or restrictions, check the source carefully. Marine collagen may be preferred by those avoiding red meat, while bovine collagen is more widely used in multi-type formulations.

How Collagen Supplements Are Used

Collagen powders are often:

• Mixed into smoothies

• Added to coffee or tea

• Stirred into yoghurt or oats

• Taken in capsule or liquid form

They are generally flavourless (or lightly flavoured) and designed to fit into a daily routine.

Collagen supplements are intended to supplement dietary protein intake and should be used alongside a balanced diet that includes a variety of nutrients.

Ingredients to Look For

When choosing a collagen supplement, consider:

1. Ingredient transparency
Look for clearly stated collagen type and source.

2. Minimal additives
Check for unnecessary fillers, artificial colours or sweeteners.

3. Third-party testing
Quality assurance and manufacturing standards matter.

4. Complementary nutrients
Some formulas include vitamin C, which contributes to normal collagen formation in the body.

Is Collagen Right for Everyone?

Collagen supplements are not suitable for vegans, as they are animal-derived. Individuals with food allergies (such as fish) should check the source carefully.

As with any supplement, it’s best to speak with a qualified health professional if you are pregnant, breastfeeding, managing a health condition, or taking medication.

The Bottom Line

Collagen is a naturally occurring protein that plays a structural role in the body. Supplements provide specific amino acids found in collagen and are commonly used as a convenient way to increase protein intake.

Choosing a high-quality product with clear labelling and appropriate sourcing can help ensure it fits your dietary preferences and lifestyle.

Always read the label and follow the directions for use.
