Vitamin D is a vital nutrient for women over 60, yet many in this age group are not getting enough. Critical for bone strength, muscle function, hormone regulation, and immune health, vitamin D deficiency is common among older women.
Registered dietitians emphasize its importance and offer guidance on how to maintain adequate levels through diet, supplementation, and safe sun exposure.
Why Vitamin D Matters for Older Women
As we age, nutritional requirements evolve, and vitamin D often rises to the top for women over 60. This fat-soluble vitamin supports hundreds of physiological processes essential for strength and resilience. Health authorities recommend adults over 50 aim for 600–800 IU (15–20 mcg) daily.
Protecting Bone Health
Bone density declines significantly after menopause due to reduced estrogen, increasing the risk of osteoporosis. “Vitamin D enables the body to absorb and utilize calcium effectively, keeping bones strong,” explains Avery Zenker, RD. Studies show that combined calcium and vitamin D supplementation can boost bone mineral density and reduce hip fracture risk in postmenopausal women.
Maintaining Muscle Strength
Vitamin D is crucial not only for bones but also for muscle function. Samantha DeVito, M.S., RD, CDN, notes that muscle tissue contains vitamin D receptors, which support contraction, coordination, and balance. Adequate vitamin D intake can reduce the risk of sarcopenia—the age-related loss of muscle mass—and help older women maintain mobility, strength, and independence.
Supporting Hormone Balance
Vitamin D regulates key hormones, including parathyroid hormone (PTH) for bone health, insulin for blood sugar control, and thyroid hormones.
Patricia Bannan, M.S., RDN, highlights a “double hit” after age 60: declining estrogen levels and reduced vitamin D production, which together can disrupt bone, muscle, mood, and endocrine health. Low vitamin D is associated with increased PTH, insulin resistance, thyroid issues, inflammation, and weaker immunity.
Boosting the Immune System
Vitamin D plays a role in both innate and adaptive immunity, helping the body respond to infections and maintain immune memory. Immune cells such as monocytes and lymphocytes rely on vitamin D to coordinate responses to bacteria and viruses. While research continues, maintaining adequate vitamin D levels may support immune health in postmenopausal women.
Vitamin D-Rich Foods
Although sunlight is a primary source of vitamin D, dietary intake is essential, particularly for those who spend time indoors or live in northern regions. Foods high in or fortified with vitamin D include:
Fatty fish (salmon, mackerel, sardines, trout)
- Eggs
- Dairy products (milk, cheese, yogurt)
- Fortified plant milks (soy, almond, oat)
- Fortified cereals
- Certain mushrooms
Other Nutrients Important for Women Over 60
Protein: Supports muscle mass, strength, and metabolism. Women over 60 should aim for at least 0.36 grams per pound of body weight daily, with higher amounts for those who exercise regularly.
Calcium: Essential for bone health. Intake often declines with age, particularly for women avoiding dairy.
Vitamin B12: Crucial for red blood cell production, nerve function, and DNA synthesis. Absorption decreases with age, and plant-based diets may require fortified foods or supplements.
Ensuring sufficient intake of these nutrients—especially vitamin D—can help women over 60 maintain strength, mobility, and overall health.
