One of the unquestioned staples of bodybuilding supplementation, ZMA is often up there with creatine and protein in terms of popularity. Rumoured to increase testosterone, muscle mass and your chance of bizarre dreams, ZMA is promoted as a cheap and effective supplement for the average gym goer.

In my own brief training experience, it’s something I’ve used on a regular basis not because of its observable benefits, but because people talk about it so damn much. So my own conformity aside, it’s important to note that ZMA’s history and effectiveness is far more suspect than we might consider. That’s putting it mildly.
