Boron is an ultra-trace element found in humans and other animals. While we know that it strengthens cell walls in plants, its role in human physiology is largely unknown.
Iranian scientists found that supplementing 10 mgs of boron from Sodium Tetra Borate (STB) per day in healthy young males for a week decreased levels of sex-hormone binding globulin, and significantly increased levels of free testosterone which makes the hormone more biologically active. Boron (STB) supplements also decreased biomarkers of inflammation such as c-reactive proteins (CRP). Lowering the level of CRPs has been shown to lower the risk of heart disease.
This is the first human study to report an increase of free testosterone after a boron supplement. This is also the first human study with boron (STB) that increased testosterone and decreased estrogen (estradiol). For more information about Sodium Tetra Borate (STB), go to stbboron.com.
