#3 – DHEA
DHEA is actually an endogenous steroid hormone found in our body, but after we turn 30, the amount of DHEA that our body produces starts to decline. This is why some men take DHEA supplements, which contain synthetic forms of this hormone, as an equivalent replacement. These supplements actually do a great job, but the problem is that they can harm your health in other ways. More specifically, it lowers the amount of the good cholesterol in your body, putting your heart health at risk.
