SHBG is a glycoprotein produced by the liver. When sex hormones are bound by SHBG, they fail to trigger their intended reaction within cells.
Since testosterone is one hormone that can be bound by SHBG, free testosterone can become scarce when there’s an abundance of SHBG in the bloodstream.
It’s easy to assume that SHBG is bad for the body because it prevents testosterone from doing its job. But, SHBG prevent the negative consequences of having too much androgen.
This is why, when the body increases its production of estrogen, it also increases its production of SHBG.
Unfortunately, this means of regulating testosterone can go out of control. Like hormones, SHBG can be affected by what goes into your body through your diet or the environment your body is exposed to.
Xenoestrogens and phytoestrogens found in processed food, plastics, and certain bath products abnormally increase the SHBG in the body.Alcohol increases the rate at which testosterone converts to estrogen, and in turn also increases the production of SHBG.
Aside from that, drugs like statins, anti-depressants, and beta-blockers cause an increase in the body’s production of SHBG. With these medications, the body produces too much SHBG that there’s inadequate free testosterone left for use.
Simply put, the body can produce excessive amounts of SHBG when exposed to certain substances. Awareness of these substances is key to having the right amount of free testosterone.
The easiest and, perhaps, most beneficial thing to do is to optimize your testosterone levels through natural means. This is because testosterone has been shown to decrease SHBG levels in the body.
In this way, your body is getting the best levels of the male sex hormone while preventing SHBG from exceeding the necessary amount. This can be done by supplementing with vitamin D, boron, and zinc.
Another way of getting the right levels of SHBG is by supplementing with magnesium. This effect has been seen on those who have at least a gram of magnesium in their daily diet.
Regardless of how you prefer to control your SHBG, doing so is crucial as testosterone is too important for the body. Having little of it can lead to detrimental consequences to your health and physique.
