16 Best Vitamins and Supplements for Women Over 50 in 2026

11. Vitamin C - Antioxidant Power and Immune Support

Vitamin C requirements may increase for women over 50 due to heightened oxidative stress, decreased immune function, and the body's increased need for antioxidant protection against age-related diseases. While severe vitamin C deficiency is rare in developed countries, suboptimal levels are common among older adults due to factors such as decreased appetite, medication interactions, and reduced absorption efficiency. For women navigating the challenges of aging, vitamin C provides essential support for immune function, collagen synthesis, iron absorption, and protection against oxidative damage. The vitamin's role in collagen production becomes particularly important for maintaining skin health, wound healing, and blood vessel integrity as natural collagen synthesis declines with age. Research suggests that adequate vitamin C intake may help reduce the risk of cardiovascular disease, support cognitive function, and enhance the absorption of plant-based iron sources, which becomes increasingly important for women with changing dietary patterns. The recommended daily allowance of 75 milligrams may be insufficient for optimal health in women over 50, with many experts suggesting 200-500 milligrams daily for enhanced antioxidant protection. Buffered vitamin C or mineral ascorbates may be better tolerated than ascorbic acid for individuals with sensitive stomachs. Time-released formulations can help maintain steady blood levels throughout the day, maximizing the vitamin's protective benefits.

12. Zinc - Immune Function and Wound Healing Support

Zinc deficiency becomes increasingly prevalent among women over 50 due to factors such as decreased dietary intake, reduced absorption efficiency, and increased losses through medications and chronic conditions. This essential trace mineral plays crucial roles in immune function, wound healing, protein synthesis, and DNA repair, making adequate intake vital for healthy aging. For women over 50, zinc supports not only immune system competence but also taste and smell sensation, which can decline with age and affect nutritional status. Research indicates that zinc deficiency may contribute to increased susceptibility to infections, delayed wound healing, hair loss, and impaired cognitive function. The recommended daily allowance of 8 milligrams for women may be insufficient for those with increased needs due to stress, illness, or certain medications. Zinc supplementation in the range of 15-30 milligrams daily can help restore optimal levels, though excessive intake can interfere with copper absorption and immune function. Chelated forms such as zinc picolinate or zinc bisglycinate offer superior bioavailability compared to zinc sulfate or oxide. Timing is crucial, as zinc should be taken on an empty stomach for maximum absorption but may cause nausea, so taking it with a small amount of food may be necessary. Women should be aware that calcium, iron, and fiber can inhibit zinc absorption, necessitating strategic timing of supplementation for optimal benefit.
