NAD chastises Natrol for claims about Promensil

NEW YORK The National Advertising Division of the Council of Better Business Bureaus on Tuesday recommended that Natrol, which distributes Promensil, a dietary supplement marketed for the relief of the symptoms of menopause, modify or discontinue certain claims for the supplement. NAD did find, however, that the advertiser had provided adequate support for certain claims.

At the outset of the NAD inquiry, Natrol explained that Promensil is a brand of dietary supplement for the relief of menopausal symptoms. The supplement contains an extract of red clover, standardized to provide four naturally occurring isoflavones, biochanin A, formononetin, genistein and daidzein. 

Following a review of each of the 22 cited studies, NAD found that while there is significant research that Promensil may provide certain benefits for menopausal women, the challenged advertising overstates the results of such research. 

Specifically, NAD determined that there was insufficient evidence to support the message conveyed by the advertiser’s claim that “22 clinical studies can’t be wrong.” NAD determined, as well, that because of conflicting efficacy research, as well as  deficiencies in many of the studies, the evidence was not sufficiently reliable to support the advertiser’s unqualified “clinically proven” claims and recommended that such claims be discontinued or modified.

NAD further recommended that the advertiser’s “Doctor Recommended” claim be modified to clearly and conspicuously disclose that the doctors surveyed were Australian and Canadian.   

With respect to claims concerning hot flashes, NAD found that, based on the current research, the advertiser can make qualified claims that more accurately reflect the current state of the science, i.e., that Promensil may help reduce the frequency and/or the severity of hot flashes.

NAD also found that Natrol provided a reasonable basis to make certain limited claims that Promensil can help relieve the frequency and/or severity of hot flashes, increase testosterone which may alleviate certain mood swings, promote breast health, promote heart health and promote emotional well-being. 

Natrol noted in its advertiser’s statement that it would modify its advertising to conform to NAD’s findings, the NAD reported. “Natrol thanks the NAD for its consideration and review of the evidence submitted to it by Natrol. Although Natrol respectfully disagrees with the decision reached by the NAD, it voluntarily accepts the NAD’s recommendations and suggestions on the claims in question,” the company stated in its letter to NAD.

Thank you, NAD, for this (2007) report on Promensil. I have just purchased this product on the recommendation of my pharmacist. Obviously, the company took your recommendations to heart and re-worded it's claims. However, I must say, in my case, that is, that the product seems to be living up to its promises/statements. I have been suffering from severe menopausal symptoms for the last six years; it's been horrible living like I have been. But, since starting the Promensil six days ago I have noticed a significant decrease in the number of hot flashes I usually have throughout the day. The severity (thank you, Jesus) of the heat and sweating is GREATLY reduced. :) So, I want to thank you for looking out for consumers and your fair reporting, and a big thank you to Natrol for putting out this great product!
