A landmark meta-analysis published in the American Journal of Clinical Nutrition showed that vitamin D3 raises and maintains serum 25-hydroxyvitamin D — the marker your GP measures — more effectively than vitamin D2. Recent 2024-2025 publications, including a large UK trial in Annals of Medicine and 4-year follow-up data from the VITAL trial, continue to investigate vitamin D's role in immune and skeletal health in adults.\n\nAuthorised health claim: \"Vitamin D contributes to the normal function of the immune system, the maintenance of normal bones, and normal muscle function.\"\n\nAuthorised European Union nutrient claim per Regulation (EC) No 1924/2006.

        "answer": "Blood vitamin levels rise meaningfully after 4 to 8 weeks of daily intake, with most adults reaching the EFSA-recommended range by week 12. Effects on energy or immune resilience vary by individual. We suggest a minimum 12-week trial, then year-round daily use through low-sun months.",
