Vitamin D is an essential fat-soluble vitamin that plays a critical role in bone health, immune function, cardiovascular health, and neuroinflammatory regulation. Initially recognized for its importance in calcium and phosphorus metabolism, recent research has expanded its role to include chronic pain management, muscle function, and disease prevention. Vitamin D is primarily synthesized through skin exposure to UVB radiation, but dietary intake and supplementation are necessary to prevent deficiencies, especially in populations with limited sun exposure. Deficiency in vitamin D is a growing global health concern and has been associated with an increased risk of osteoporosis, autoimmune diseases, cardiovascular disorders, and neurodegenerative conditions. This review examines recent findings on vitamin D’s impact on various physiological systems, including its influence on chronic musculoskeletal pain, athletic performance, and immune modulation. Additionally, the review explores the risks of excessive supplementation, highlighting the importance of precision dosing. Furthermore, alternative approaches, including Homoeopathy, have been suggested for addressing vitamin D-related deficiencies. Remedies such as Calcarea Phosphorica 6X have been proposed as potential supportive therapies to enhance vitamin D metabolism. However, while Homoeopathic interventions may offer complementary benefits, conventional vitamin D supplementation remains the primary method for addressing deficiencies. Despite advances in understanding the role of vitamin D, research gaps remain regarding optimal dosage, long-term effects, and its interaction with other micronutrients. A multidisciplinary approach combining conventional medicine with emerging therapies may provide a holistic strategy for managing vitamin D-related health conditions. Future studies should focus on personalized supplementation strategies to maximize benefits while minimizing risks.
