Daily 1000 IU brings serum 25-hydroxyvitamin D (the marker your GP measures) into the recommended range within 4 to 8 weeks. The form here is cholecalciferol — D3. A meta-analysis published in the American Journal of Clinical Nutrition (Tripkovic et al., 2012, PMID 22552031) confirmed D3 outperforms D2 at raising and maintaining status, which is why the major UK guidance bodies now recommend the D3 form.\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.

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.",
