Collagen craze: Does this popular supplement really work?

The health and wellness scene is always riding a new craze and in the last few years 'collagen' has been hailed as the latest must-use supplement.

Collagen is the most abundant protein in the body and helps to keep our skin plump, our joints and bones strong, and our hair and nails healthy.

But is the buzz around this supplement warranted?

Is there credible science to support that taking it will supplements can replenish our dwindling supply? And if so, what's the best way of getting it into our bodies? 

Registered dietitian and spokesperson for the Association for Dietetics in South Africa, Elske Rich says collagen in made in our bodies from the amino acids we eat.

"Amino acids are like the building blocks of protein."

So why the need to supplement, if our bodies already make collagen?

Rich explains that our collagen supply naturally starts to decrease, on average around 1% a year, as we reach our mid to late 20s. 

"That's why there is this interest in the supplement."

Rich adds that the effect of taking a collagen supplement are not felt overnight.

It's important to take it for 8-12 weeks, she says.

"Most of the studies have show small measurable improvements in skin elasticity or hydration or fine lines only after 8-12 weeks, and that's when it's above 2.5 grams a day of hydrolized collagen.

It's something we need to stick with and not look at as a quick fix says Rich.
