Inevitably, as men age, our testosterone levels will begin to decrease over time. This starts to occur around 25 years of age. The biggest decline occurs after age 35. Some conditions that are attached with having low T are, feeling fatigue, little or low libido, mind fog and the inability to put on muscle mass at the gym. In 2011 there was a study that was published in the Journal of Trace Elements in Medicine and Biology where boron was added as a supplement for men. What they found in several test studies was an increase in men’s steroid hormone level in the form of free testosterone. FREE testosterone is defined as the amount of testosterone that it is not bound to the sex hormone binding globulin (SHBG ). Free testosterone plays and important role in bodybuilding or looking young. Testosterone has been studied increasingly over the last couple of decades. In 1997 researchers conducted a study using 10 mg per day and witnessed an increase in both testosterone and estrogen levels after 4 weeks. The key component in the study was that boron was being consumed daily, with a chemical loss of 84% excreted in urine. The 84% loss sounds like a lot, but it has a high level of bioavailability when compared to most other supplements. The quick results: Free testosterone increase almost 30%, Vitamin D3 increased almost 20% and DHEA increased 56%. Please ask a doctor or health professional prior to taking any supplement. In the case of taking minerals, keep in mind that they are not passed out of your body quickly and can become toxic at levels greater than 20 mg per day, which is the Tolerable Upper Limit (TUL) of boron. My daily intake of boron is 3mg three times per day totaling 9 mg per day. My first noticeable observation that I experienced was a dramatic increase in my weightlifting routine. This observation was noted in my maximum weight that I was able to lift during the workout. Also, I was able to complete a higher number of repetitions. I noticed that this increase occurred after 24 days of consistent boron usage.
