PARSIPPANY, N.J., Feb. 2, 2011 /PRNewswire/ -- DSM Nutritional Products today announced a new study published in the international peer-reviewed journal, Maturitas, that offers new hope for women suffering from hot flashes and night sweats.(1) The data shows that geniVida®, a non-soy, non-hormonal genistein dietary ingredient and the active ingredient in DSM's i-cool™, is a safe and effective non-drug option for the management of hot flashes and night sweats in postmenopausal women.


"These findings are encouraging for the 42 million women aged 45 years and above in the United States who experience these menopausal symptoms(2)," said Dr. Malkanthi Evans, Scientific Director, KGK Synergize Inc. and lead study author.

These new data demonstrate that of the subjects who completed at least 4 weeks on trial (n=40), the women on geniVida experienced an average of 51% reduction in hot flashes and night sweats by week 12 compared to only 27% for the placebo group (p<0.026), a highly statistically significant difference.  The corresponding reduction in total duration of hot flashes and night sweats per day was also statistically significant. Additionally, although not reported in the publication, the study showed 28% of the women in the geniVida group experienced an 85% reduction in their hot flashes (p<0.0002).

"This exciting new study reinforces the proven efficacy and safety of geniVida, the active ingredient in DSM's i-cool supplement," said James Elliott, Ph.D. director of nutritional science for DSM Nutritional Products. "i-cool has already helped tens of thousands of women manage their hot flashes and night sweats and we look forward to the relief this product can bring to the millions of other women who suffer from these symptoms."

About the Study

This randomized, double-blind, placebo-controlled study was conducted at five clinical centers in Ontario, Canada under the highest scientific standards. The study participants included 84 healthy postmenopausal women between the ages of 40 and 65, suffering from a minimum of 40 hot flashes or night sweats per week and in a physiological state of natural or surgical menopause. The participants were randomly assigned to consume placebo or a single 30 mg daily dose of geniVida for 12 weeks.

There was no significant difference between subjects on geniVida or placebo with respect to the number of subjects who experienced at least one adverse event.
