In 2006, actress Suzanne Somers released the book "Ageless: The Naked Truth About Bioidentical Hormones" endorsing the use of bioidentical hormones. The book was criticized by a group of doctors who (though generally supportive of BHT) state that more research is required, and object to protocols mentioned in the book—because of their potential danger and the promoters' lack of qualifications. Somers' book may have increased awareness of the existence of BHT for a growing number of menopausal women, but also may have caused confusion by making unsubstantiated claims for BHT and referring to bioidentical hormones as non-drug products with fewer risks. Bioidentical hormones have also been discussed on "The Oprah Winfrey Show", with Somers as a guest.
