Could Hair Loss Signal a Vitamin D Deficiency After 50—and How to Fix It
Many midlife women may have subtle vitamin D deficiency that shows up as fatigue, frequent illness, bone or back pain, muscle weakness, mood changes—and even hair thinning. Restoring vitamin D can improve bone health, immunity, and weight management, with some studies suggesting lower dementia risk when levels are adequate. Boost levels through modest sun exposure (about 10 minutes midday, several days a week), foods rich in vitamin D (fatty fish, egg yolks, fortified milk/yogurt/juices), and vitamin D3 supplements, while avoiding doses above 4,000 IU daily unless directed by a doctor; a blood test is recommended to guide dosing.
