NAD cites Green Willow Tree for overstatement of Thyodine effects


NEW YORK The National Advertising Division of the Council of Better Business Bureaus on Wednesday recommended that Green Willow Tree discontinue certain advertising claims for its Thyodine dietary supplement product, including that its product is a “safe, all-natural hormone,” and that “Thyodine helps to stimulate the thyroid gland to produce normal amounts of thyroid hormone again.”

In its defense, Green Will Tree maintained that Thyodine includes vitamins, amino acids, minerals, supplemental glandulars and other ingredients that have been generally accepted in the scientific and medical community as beneficial to, and supportive of, thyroid function.  

However, NAD determined that the advertiser’s claims go beyond the simple message that Thyodine contains ingredients that have been shown to help support a healthy thyroid.

The company, in its advertiser’s statement, noted that it does not “fully agree with the conclusions.”

However, the company said that it would adjust advertising for Thyodine to “attempt to meet the recommendations submitted … by NAD.”

The claims were challenged by the Council for Responsible Nutrition, a trade association of dietary-supplement manufacturers.
