It seems that it has become synonymous to suggest a supplement when trying to improve your health and fitness. The real question here shouldn't be which supplement you need, but rather, do you really need one to begin with?
You can't search the internet or browse social media any more without seeing an advertisement claiming to cure what ails you.
After working almost a decade in sales for a nation wide supplement chain, one thing the customers taught me was that most of them wanted a fix to whatever problem they had. Most of the time, it didn't have to be a quick fix, just a fix to something they didn't think they were capable doing on their own.
The real question is whether or not the supplement they were buying actually was doing what they had hoped it was doing.
