"Perimenopause & Heart Health: How Vitamin D and Hormones Impact Women in Their 40s & 50s"

Dr. Haver positions this supplement protocol as a direct response to the new study showing that perimenopausal women with low vitamin D and high fasting glucose have a 5-fold increase in arterial thickening. Given that 80% of her patients are vitamin D deficient and perimenopause already elevates FSH-linked arterial risk, she proactively recommends repletion. She doesn’t advocate waiting for bone loss or a fracture; the argument is now cardiovascular. The dosing at 4,000 IU is higher than many standard multivitamins (often 400–800 IU) and reflects a therapeutic repletion approach. She mentions that the specific product she takes and recommends combines the D3 with omega-3s and vitamin K, noting the combination is important for absorption. This reflects a practical, integrated formula rather than taking separate pills. While she doesn’t name a brand in this clip, it aligns with her clinical brand where she formulates supplements for women in menopause.

Dr. Haver breaks down a brand-new study that measured vitamin D, FSH, fasting glucose, and carotid intima-media thickness in 227 women ages 40–59, all in perimenopause or early menopause with hot flashes. Low vitamin D was independently associated with thicker arterial walls. FSH, which surges during this life stage, also independently associated with thickening. Fasting blood glucose was a risk factor at every age. The most alarming finding: in women under 50, the combination of low vitamin D and high fasting glucose produced a 5.1-fold increase in arterial wall thickness—five times the risk. She frames this as evidence that the ‘hormonal chaos of perimenopause is leaving a mark on our arteries before you have a single symptom of disease.’ This challenges the notion that cardiovascular prevention in women should wait until after menopause; the damage is already accumulating, and modifiable factors like vitamin D and glucose control offer a window for intervention. She ties this directly to her clinical experience, where 80% of her patients have sub-optimal vitamin D levels, and she already checks fasting glucose, insulin, and HOMA-IR on everyone—making the study actionable for her practice immediately.

Dr. Haver describes that eight out of ten women she sees for menopause symptoms have sub-optimal vitamin D levels. This is not a cherry-picked statistic—it’s the reality of her daily practice. She uses this to justify why she checks a comprehensive metabolic panel including fasting insulin and HOMA-IR on all her patients, not just vitamin D and glucose. The high prevalence means that many women are walking around with a deficiency that, combined with rising FSH and often dysregulated glucose, is silently thickening their arteries. She urges women to ask their doctors for these specific labs, moving beyond bone-centric thinking around vitamin D to a cardiovascular and metabolic lens. This observation turns the abstract study finding into a concrete, common scenario: if you’re a perimenopausal woman with hot flashes, there’s a very good chance your vitamin D is low and your glucose may be higher than ideal, and together that’s a 5-fold risk amplifier.
