What Is Free Testosterone?
Your body has total testosterone and free testosterone. Total testosterone is all the testosterone in your blood. But some of it is bound to proteins. The rest is free testosterone. This free part is active and can enter cells to work.
Doctors say free testosterone shows your real hormone level. If free testosterone is low, you might feel tired or weak. So, boosting free testosterone can improve energy and health.
How Do Supplements Work?
Supplements can help raise free testosterone in different ways. Some increase total testosterone. Others lower the proteins that bind testosterone. Some help the body make more testosterone naturally.
Remember, supplements are not magic pills. They work best with a good diet, exercise, and rest. Let’s see some supplements that may help raise free testosterone.
