Ingredients: Avela contains l-arginine, eurycoma longifolia, cniddium monnier 50% extract, xanthoparmelia scabrosa extract, GABA, epimedium sagittatum, butea superba extract, avena sativa extract, mucuna pruriens extract, ginkgo biloba, maca root extract, tribulus terrestris extract, muira puama extract and bioperine.
Does it Work?: It might. According to a study reported in the 2003 issue of Phytomedicine, male rats who were fed eurycoma longifolia displayed an increase in testosterone and sperm count, suggesting it may improve the body's reproductive processes. Another study, which was conducted by the same researchers, also revealed it may strengthen the vessels that facilitate erection strength. Cathy Wong, an alternative medicine expert for About.com, also identifies l-arginine and ginkgo biloba as natural remedies for erectile dysfunction. She claims both ingredients facilitate blood flow to the penis, making it easier for men to get--and maintain--an erection.
None of these ingredients have been proven effective by national studies, however. Most of its reported effects occurred in small, animal or human-controlled studies, and have only been replicated in a few follow up studies. There isn't enough evidence that confirms it absolutely can improve problems associated with erectile dysfunction--it only suggests they may be viable treatments.
Is it Safe?: No. Ginkgo biloba can cause gastrointestinal (GI) irritation, nausea, vomiting, diarrhea, dizziness, heart palpitations and an increased risk for bleeding. People taking antidepressants or anticoagulants should speak with their physician prior to using Avela. Xanthoparmelia scabrosa is also a known toxic herb--regular use is not recommended.
Grade: C+. Not enough studies prove Avela's ingredients have the efficacy to improve the ability to maintain erections. Although some studies suggest it may improve erection strength, they haven't demonstrated these abilities in numerous studies. The risk of unwanted side effects is also a huge disadvantage, especially if you have a history of bleeding or gastrointestinal disorders. GRADE C+
