The Perimenopause Solution Podcast - A podcast by Tara Thorne

Many women don’t realize there’s a big difference between synthetic progestins and natural bioidentical progesterone when it comes to hormone support. In this short episode, Tara breaks down the key distinctions between these two types of progesterone, explaining why bioidentical forms are the safest and most effective option for women in midlife. Tara highlights the potential harms of synthetic progestins—which are commonly found in birth control pills, certain IUDs, and some hormone replacement therapies—including increased risks of breast cancer, negative cardiovascular impacts, mood disturbances, and more. In contrast, natural bioidentical progesterone supports sleep, mood, brain health, and overall well-being, without the risks associated with its synthetic counterparts. If you’re on hormone therapy or using birth control, Tara encourages you to check what type of progesterone you’re taking and consider making a switch if necessary. This episode is full of clear, empowering information to help you make the best choices for your long-term health as you navigate perimenopause and beyond.
