Important Safety Information
Do not exceed 4,000 IU/day without medical supervision. High doses over long periods can cause vitamin D toxicity. Get your levels tested every 3-6 months when supplementing. Symptoms of toxicity include nausea, vomiting, weakness, and kidney problems.
This calculator provides general guidance based on common recommendations. Optimal dosing depends on individual factors including genetics, medications, and health conditions. Consult a healthcare provider, especially if you have kidney disease, sarcoidosis, or take medications affecting calcium metabolism.
