I have some in my cupboard. And I'm far from alone - creatine has become the supplement of choice for millions.
Originally known for enhancing the performance of bodybuilders and athletes in the 1990s, this white powder is now entering the spice cupboards (well, that's where I store mine) of women in their 40s.
It's arguably one of the world's most researched supplements. Thousands of studies have been carried out over the past few decades evaluating its ability to increase muscle mass and overall strength.
"Creatine has become so big, you feel that if you are not using it, you are kind of losing out," says Dr Henry Chung, a lecturer in sport and exercise science at the University of Essex. "It's moved from elite sport into the mainstream. It's not about whether to take it anymore, it's about when to take it - before or after exercise? Everyday? How much?
"In which form is best? Powder, tablets, gummies?"
