Methoxyisoflavone for Sports & Fitness
Methoxyisoflavone is a member of the family of flavonoids (isoflavones). In a U.S. patent, the developers of this substance claim, based on preliminary animal research, that it possesses muscle-building and bone-building (anabolic) effects without the side effects seen with either androgenic (male) hormones or estrogenic (female) hormones.1
Why Do Athletes Use It?*
Some athletes say that methoxyisoflavone improves muscle mass gains from strength training without undesirable hormonal side effects.
What Do the Advocates Say?*
Methoxyisoflavone is a recently developed supplement related to the flavonoid family. Only one preliminary human trial has tested its effects on body composition changes with exercise. Although results were promising, double-blind research is needed to confirm them.
How Much Is Usually Taken by Athletes?
Methoxyisoflavone is a member of the family flavonoids (isoflavones). In a U.S. Patent, the developers of this substance claim, based on preliminary animal research, that it possesses anabolic (muscle-building and bone-building) effects without the side effects seen with either androgenic (male) hormones or estrogenic (female) hormones.2 A preliminary controlled trial found that strength-training athletes who took 800 mg per day of methoxyisoflavone for eight weeks experienced a significantly greater reduction in percentage body fat than those who took a placebo.3 Double-blind research is needed to confirm these findings. The U.S. patent also claims methoxyisoflavone reduces appetite and lowers blood cholesterol levels. Whether this claim is true has not yet been demonstrated in published scientific research
