Vitamin D and PMOS – What's the Link?

Vitamin D is one of the most common nutrient deficiencies in women with PMOS (Polycystic Metabolic Ovarian Syndrome), but its role extends far beyond bone health.

In this episode of It's Not You, It's PMOS, fertility dietitian Lora Attia and co-host Nick Nation explore the growing evidence linking Vitamin D to insulin resistance, hormone regulation, ovulation, fertility, inflammation, mood, and overall metabolic health.

You'll learn:

• Why Vitamin D functions more like a hormone than a vitamin.
• Why Vitamin D deficiency is more common in women with PMOS.
• How low Vitamin D levels are associated with insulin resistance, elevated androgens, irregular periods, and fertility challenges.
• The role of Vitamin D receptors in the ovaries, uterus, and other reproductive tissues.
• Common mistakes people make when taking Vitamin D supplements.
• When testing and supplementation may be appropriate.

Whether you're trying to improve your fertility, manage PMOS symptoms, or better understand your metabolic health, this episode provides practical, evidence-based information to help you make informed decisions.
