Study Finds Vitamin D Increases Chemotherapy Response in Breast Cancer

Vitamin D is essential for bone health by aiding calcium and phosphorus absorption, with deficiency leading to conditions such as rickets in children and osteomalacia or osteoporosis in adults. Despite sufficient sun exposure, many people remain vitamin D deficient due to complex factors like skin melanin levels affecting vitamin D synthesis. Recent studies suggest vitamin D supplementation may slow cellular aging by reducing telomere shortening, though the clinical significance requires further research. Additionally, low-dose vitamin D supplementation has shown promise in enhancing chemotherapy effectiveness in breast cancer patients, offering a cost-effective adjunct to treatment. While vitamin D supports immune function and disease resistance, excessive intake can cause toxicity, highlighting the need for balanced supplementation. Foods rich in vitamin D and responsible sun exposure remain important for maintaining adequate vitamin D levels.
