Description
Nivagen Vitamin D3 Cholecalciferol 50,000 IU capsules provide high-potency vitamin D supplementation for individuals with severe deficiency or those requiring intensive repletion therapy. Each capsule delivers 50,000 International Units of vitamin D3, the most bioactive form of vitamin D, which is essential for calcium absorption, bone health, immune function, and overall wellness. This pharmaceutical-grade supplement is typically prescribed for patients with documented vitamin D deficiency or those at high risk for deficiency due to limited sun exposure, dietary restrictions, or absorption issues. The 100-capsule bottle provides a substantial supply for long-term therapy under medical supervision. Vitamin D3 (cholecalciferol) is the preferred form over D2 (ergocalciferol) due to its superior absorption and longer duration of action. Leader Brand ensures consistent potency and purity through rigorous testing and quality control measures. These capsules are ideal for healthcare providers treating patients with conditions such as osteoporosis, osteomalacia, or chronic kidney disease where high-dose vitamin D supplementation is medically necessary.
Suggested Use
Take one capsule weekly or as directed by healthcare provider. Best absorbed when taken with a meal containing healthy fats. Typical regimen is once weekly for 6-8 weeks for deficiency correction, then maintenance dosing as prescribed. Do not exceed recommended dosage without medical supervision.
