Mention testosterone and most people think of aggressive men, bodybuilders and steroid abuse. Phrases such as "Too much testosterone." have painted the humble hormone in a bad light for decades.
However, having too much testosterone is often not the problem, especially for men in their forties and fifties. The far more serious issue is having too little testosterone.
Testosterone, a steroidal hormone made in the testicles, essentially makes men...well, men. It's responsible for a host of vital functions including, but not limited to:
Red blood cell development
Maintaining healthy testosterone levels, therefore, is crucial for optimum health. And therein lies the problem because testosterone levels naturally decline as you move beyond your thirtieth birthday. Each year, you lose around 1% of your testosterone production, and that's assuming you're living the good life.
If you factor in several other lifestyle habits and traits that tend to develop as we get older, things only get worse:
Excess weight and body fat
Lack of exercise
Poor sleep quality
