Mary Tyler Moore Exposes Premarin (VIDEO)

Watch as Mary Tyler Moore shares the secret ingredient of Premarin: Cruelty and suffering to horses and their foals.

Every year, doctors prescribe hormone replacement therapy (HRT)—also referred to as menopausal hormone therapy—to hundreds of thousands of women experiencing menopausal symptoms. One of the HRT drugs that has historically been among the most widely prescribed is made from animal waste. The drug is Premarin, an estrogen-therapy drug currently manufactured by Pfizer (formerly Wyeth Pharmaceuticals), which also produces Prempro, an estrogen/progestin combination. Both drugs contain horse urine, specifically pregnant mare’s urine (PMU). Not only has this form of HRT proved to be dangerous to humans, horses raised for their urine are also kept confined and pregnant, and their foals often end up in the slaughterhouse.
