This review explores the multifaceted impacts of vitamin D deficiency on overall health and investigates diverse strategies for addressing this issue. Vitamin D deficiency presents a global health issue with notable implications for cardiovascular, immune, and brain health. Strategies to address deficiency encompass dietary modifications, food fortification, and supplementation. Serum 25(OH)D concentration serves as a crucial biomarker, with levels below 20 ng/mL being indicative of deficiency. Tailored supplementation regimens, often favoring vitamin D3 for its enhanced bioavailability, necessitate careful consideration to avoid toxicity risks. The incorporation of vitamin D-fortified foods into dietary patterns presents a promising systematic approach to mitigating deficiency and promoting overall health. The Functional Food Center's regulatory process offers a structured framework for creating products fortified with vitamin D, emphasizing the importance of regulatory compliance and clinical validation. While existing evidence underscores the efficacy of fortified products, ongoing epidemiological and post-market research is imperative to fully establish their status as functional foods.
