Does vitamin D help with irregular periods during perimenopause?

Some women find that vitamin D helps manage irregular periods during perimenopause, though individual results vary. The connection between vitamin D and irregular periods involves how this supplement interacts with the hormonal and neurochemical pathways that become disrupted during perimenopause.

The evidence for using vitamin D specifically for irregular periods ranges from anecdotal reports to clinical studies. What matters most is whether it works for your body. Many supplements need 4 to 8 weeks of consistent use before you can fairly evaluate their effect on symptoms like irregular periods.

If you want to try vitamin D for irregular periods: Start with a lower dose, choose a reputable brand with third-party testing, and track your irregular periods severity daily so you have objective data. Continue your other management strategies (sleep, exercise, stress reduction) while testing vitamin D so you can isolate its effect.

Always check with your healthcare provider before starting vitamin D, especially if you take other medications or have existing health conditions.
