Testofen is a dietary supplement produced by Gencor Nutrients, which claims that the supplement helps maintain healthy sexual desire and vitality, muscle mass and free testosterone levels in men. It is comprised of a fenugreek extract, known as Trigonella foenum-graecum, and other minerals, according to the National Institutes of Health.
According to Gencor Nutrients' website, Testofen is a unique extract of fenugreek standardized to Funuside, a proprietary mix of saponin glycosides. The company claims that supplementing diets with Testofen and regular exercise can help men maintain healthy testosterone levels in order to support multiple body functions.
In a study reported by the NIH, researchers investigated the effects of Testofen on the male libido in a double blind clinical study. The study was conducted on healthy males without erectile dysfunction ages 25 and 52 who were given either an oral dose of 600 milligrams of Testofen per day or a placebo for six weeks. The researchers concluded that Testofen had an overall positive effect on both qualitative satisfaction scores and physiological aspects of the libido, including sexual arousal and orgasm. Though it did not have any effect on mood or sleep, Testofen had a positive effect on self-reported satisfaction with muscle strength, energy and well-being. The supplement, as reported by the study, may help to maintain normal healthy testosterone levels.
