5-Methyl-7-Methoxy Isoflavone health benefit Methoxyisoflavone supplement and body building, does it work?

5-Methyl-7-Methoxy Isoflavone health benefit and review of research studies

5-Methyl-7-Methoxy Isoflavone is touted as a beneficial supplement for body building. If you wish to improve muscle strength, you are better off using Creatine powder supplements, they work much better to increase muscle size.

Research
Studies with 5-Methyl-7-Methoxy Isoflavone supplements in humans are quite limited. We believe that claims about this supplement are, at this time, premature.

5-Methyl-7-Methoxy Isoflavone claims
If you search the internet, you will see claims such as, "5-Methyl-7-Methoxy Isoflavone is a sensational, non-steroidal anabolic isoflavone, 3 times more potent than ipriflavone for increasing muscle mass and endurance. What does 5-Methyl-7-Methoxy Isoflavone research say? Not much.

Methoxyisoflavone study
Effects of methoxyisoflavone, ecdysterone, and sulfo-polysaccharide supplementation on training adaptations in resistance-trained males.
J Int Soc Sports Nutr. 2006 Dec 13;3:19-27. Wilborn CD, Taylor LW, Campbell BI, Kerksick C, Rasmussen CJ, Greenwood M, Kreider RB. Human Performance Lab, University of Mary Hardin Baylor, Belton, TX.
Methoxyisoflavone, 20-hydroxyecdysone, and sulfo-polysaccharide have been marketed to athletes as dietary supplements that can increase strength and muscle mass during resistance-training. However, little is known about their potential ergogenic value. The purpose of this study was to determine whether these supplements affect training adaptations and/or markers of muscle anabolism/catabolism in resistance-trained athletes. Forty-five resistance-trained males were randomly assigned to ingest in a double blind manner supplements containing either a placebo; 800 mg/day of Methoxyisoflavone; 200 mg of ecdysterone; or, 1,000 mg/day of sulfo-polysaccharide for 8-weeks during training. Results indicate that Methoxyisoflavone, ecdysterone, and sulfo-polysaccharide supplementation do not affect body composition or training adaptations nor do they influence the anabolic/catabolic hormone status or general markers of catabolism in resistance-trained males.
