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
Where is it found?
Several substances similar to methoxyisoflavone are found in many plants and some foods, including soybeans. Whether methoxyisoflavone itself is found in nature is unknown.
Methoxyisoflavone has been used in connection with the following conditions (refer to the individual health concern for complete information):
| Science Rating | Health Concerns |
|---|---|
 | Athletic performance |
 Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit. | |
Who is likely to be deficient?
Methoxyisoflavone is not an essential nutrient, so no deficiencies are possible.
Are there any side effects or interactions?
Hormones with anabolic effects on muscle often have side effects that include acne, male-pattern baldness, prostate enlargement, and lower high-density lipoprotein (HDL; “good”) cholesterol. Whether methoxyisoflavone can cause these side effects has not been investigated.
