Do collagen supplements actually work? We did some digging

Collagen—it’s basically the fundamental components that make up your skin, muscles, bones and ligaments. This naturally occurring protein in your body provides structural support while helping with joints and skin elasticity to give you that youthful look. However over time and with age, our bodies produce less and less resulting in wrinkles and sagging skin. Enter: collagen supplements.

To give yourselves an extra boost of collagen when we can’t make enough, many are turning to supplements to improve the appearance of skin. But do they actually work? We take a deep-dive into the world of collagen supplements and if they’re really what they chalk up to be. 

Is a collagen supplement good for you?

There’s no denying we’re flooded with anti-aging rhetoric. Wrinkles = bad so we (especially as women) are told that any lines, wrinkles and sagging of the face is something we should address immediately. So it’s little wonder more and more collagen-based products have entered the market. These supplements are designed to improve the look of wrinkles and skin elasticity, increase skin hydration, while also supporting generally healthy skin, nails and hair. 

In 2019, US university researchers found collagen supplements do in fact work. Four of the five studies hard reported improvement in the skin when supplements were taken. The report found skin moisture and collagen density, skin hydration, wrinkling and elasticity, skin moisture and roughness were all improved.

However, as Clare Collins, Laureate Professor in Nutrition and Dietetics from the University of Newcastle correctly pointed out, while the results leaned favourably towards supplements, the research was flawed. The supplements and the subjects varied across trials which made it difficult to make a like-by-like comparison, and the research was funded by cosmetic companies. 

While collagen supplements aren’t necessarily “bad” for you, it’s difficult to paint with a broad stroke if they’re good for everyone. While some may see great improvement across skin concerns, some may not see any results.

At what age should I take collagen supplements?

The way we show signs of aging can depend a lot on environmental factors (like UV rays or smoking), our skin tones and our race. However most research agrees the production of collagen begins to slow down in our mid-20s, and continues to decrease into our 30s and 40s. 

Aussie beauty brand Vida Glow suggests taking a preventative approach. You can begin to take collagen supplements as soon as you hit these milestone ages or when you begin to notice changes to your skin, hair and nails. 

Who should not take collagen supplements?

There are a number of things you should consider before taking a supplement. These include:

• If you have dietary restraints – Many supplements have animal products which are unsuitable to vegetarians or vegans. 
• If you have certain medical conditions – Those prone to gout should not take these supplements.  
• If you are taking any other forms of medication – Speak to your doctor if you’re receiving treatment for other issues or if you’re pregnant as this may impact your ability to safely take collagen supplements.
