WESTCHESTER COUNTY, NEW YORK - JANUARY 24, 2006 - ConsumerLab.com announced today that it found only six out of eleven supplements used for sexual enhancement to contain key ingredients listed on their labels and meet other quality criteria. Products failed testing due to lead levels or for containing lower levels of compounds than expected.
Testing focused on the products made with yohimbe, L-arginine, or epimedium ('horny goat weed') due to their popularity and evidence supporting their use. Results for supplements made with ginseng, DHEA and acetyl-l-carnitine, which may also provide benefit, are available in separate Reviews on the ConsumerLab.com website.
The testing included popular products such as ArginMax for Women, Excite Male Performance, Libido-Max, and Source Naturals Male Response as well products from Bodyonics (Pinnacle), Natrol, Nature's Harmony, Planetary Formulas, Progressive Laboratories (PL), TwinLab, and Ultimate Nutrition. Products were also screened for possible adulteration with pharmaceuticals, such as those in Viagra, Cialis, and Levitra. Spiking with these agents has been reported in some supplements but was not found in the products tested.
In addition to products selected by ConsumerLab.com, two products are included in the report for passing the same testing through ConsumerLab.com's Voluntary Certification Program. These products are from Nature's Bounty and Puritan's Pride. A product from Vitamin World is also noted in the report for being identical to a product that passed testing.
The new report is available at http://www.consumerlab.com/results/sexen.asp. The report provides results for each product, ingredient comparisons, expert tips on buying and using these supplements, and potential side effects. Reviews of other popular types of supplements are also available at www.consumerlab.com. New Reviews to be released in coming weeks include prostate supplements (saw palmetto and beta-sitosterol), calcium and vitamin D, probiotics, garlic, and supplements to help prevent cancer (green tea, selenium, and lycopene).
