What Is Collagen and Why Is Everyone Talking About It?

Scroll through any wellness feed and you will not get far before collagen appears. It is stirred into coffee, sold as flavoured powders, added to drinks and promised on the labels of countless skincare products. For something most of us never thought about a few years ago, collagen has become one of the most talked-about words in health and beauty. So what is it really, and does it deserve the attention?

Here is a clear, no-nonsense look at what collagen is, what it does, and how you can support your body's own supply through the food you eat.

What collagen actually is

Collagen is a protein, and it is the most abundant one in the human body. Think of it as a kind of scaffolding. It gives structure and strength to your skin, bones, tendons, ligaments and cartilage, and it helps hold everything together. When people describe skin as firm and bouncy, collagen is a big part of what they are picturing.

Your body makes its own collagen naturally, building it from the amino acids in the protein you eat. The trouble is that production gradually slows with age. From your mid-twenties onwards, natural collagen levels begin to dip, and this is one of the reasons skin loses some of its elasticity and joints can start to feel less supple over time. That slow decline is a big part of why collagen has captured so much interest.

Why it became so popular

Most of the buzz centres on two areas: skin and joints. Supplement makers point to research suggesting that collagen may help support skin elasticity and hydration, and some studies have looked at its role in joint comfort for active people. The idea of a single ingredient that supports both how you look and how you move is an easy one to get excited about.

It is worth keeping a level head, though. Research into collagen supplements is still developing, results vary between studies, and a supplement is never a substitute for a balanced diet and a healthy lifestyle. If you do try a collagen product, treat it as one small part of the picture rather than a miracle fix.

Is there collagen in plants?

This is where a lot of confusion creeps in. Collagen is an animal protein, which means it is found in the skin, bones and connective tissue of animals and fish. There is no collagen in plants, so any product labelled as vegan collagen does not actually contain the protein itself.

What these plant-based products usually offer instead is a blend of nutrients that help your body build its own collagen. That is a meaningful difference, and it is good news for anyone following a plant-based diet. You do not need to eat collagen to make collagen. You simply need to give your body the right building blocks.

Feeding your body's own collagen supply

Your body produces collagen using protein alongside a handful of key nutrients, and vitamin C is one of the most important. Without enough vitamin C, the body simply cannot make collagen properly, which makes it a genuine star of the show rather than a nice-to-have.

To support natural collagen production, aim for a diet rich in protein from foods such as beans, lentils, nuts, seeds and wholegrains, plenty of vitamin C from fruit and vegetables, and a good range of colourful plants that deliver the zinc, copper and antioxidants your body uses along the way. Berries, citrus fruits, peppers, leafy greens and pumpkin seeds are all worth a regular place on your plate.

If you want a simple way to top up your vitamin C intake, our pure Vitamin C Powder stirs easily into water, smoothies or juice. Since vitamin C plays such a direct role in collagen formation, it is one of the most sensible things to keep in the cupboard, whether or not you ever reach for a collagen product.

Focus on nutrition

Collagen is having its moment for a reason. It is the protein that keeps skin, joints and connective tissue strong, and its natural decline with age explains why so many people are keen to top it up. Whether you choose a supplement or not, the most reliable approach is the least glamorous one: eat well, include plenty of protein and vitamin C, and give your body the raw materials it needs to keep doing what it does best.

Talked about as it is, collagen is really just a reminder of something simple. Look after your body from the inside, and it tends to show on the outside.
