What if the same hormone responsible for breastfeeding is also suppressing ovulation, lowering libido, and impacting your mood?

In this episode, we break down prolactin, a hormone produced by the pituitary gland that plays a critical role in fertility, reproductive health, and dopamine regulation.

While prolactin is essential for breastfeeding, elevated levels outside of pregnancy and postpartum can disrupt ovulation, reduce sexual desire, and interfere with overall hormone balance.

We explore the most common causes of high prolactin, including chronic stress, poor sleep, over-exercising, and certain medications. You’ll also learn how prolactin interacts with dopamine and why this connection matters for both fertility and mood.

Finally, we walk through natural ways to support healthy prolactin levels, including key nutrients like vitamin B6 and magnesium, along with simple lifestyle shifts that can help restore hormonal balance.

If you’re struggling with irregular cycles, low libido, or unexplained fertility challenges, this is a conversation you don’t want to miss.
