Product Name & Strength: Nature's Field Vitamin D3 50,000 IU, 30 Capsules.
Indications (Approved Uses): Pharmacologically indicated for the intensive treatment and management of severe vitamin D deficiency in adults. It is universally utilised for the short-term loading phase of vitamin D repletion, the prevention and treatment of osteomalacia, and as a potent adjunct in the management of osteoporosis. Furthermore, high-dose cholecalciferol may be indicated in specific clinical conditions affecting vitamin D absorption or metabolism, such as hypoparathyroidism.
Contraindications (Safety Warnings): Hypersensitivity to cholecalciferol or any excipients in the formulation. This extreme high-dose preparation is strictly contraindicated in patients with hypercalcaemia, hypercalciuria, hypervitaminosis D, severe renal impairment, or calcium-based renal calculi (nephrolithiasis). Extreme caution is required in patients taking cardiac glycosides (such as digoxin) due to the increased risk of fatal arrhythmias exacerbated by hypercalcaemia, as well as in patients taking thiazide diuretics. It should be used with significant caution in patients with sarcoidosis or other granulomatous disorders due to an inherent increased sensitivity to vitamin D.
Side Effects (Adverse Reactions): Generally well-tolerated when dosed correctly according to baseline serum 25(OH)D levels. Adverse effects are almost exclusively associated with overdosage leading to hypercalcaemia or hypercalciuria. Symptoms of vitamin D toxicity include nausea, vomiting, constipation, anorexia, a metallic taste in the mouth, polyuria, polydipsia, muscular weakness, fatigue, and confusion. Chronic toxicity may result in irreversible renal damage, ectopic soft tissue calcification, and cardiac arrhythmias.
Active / Nutritional Information: The active formulation consists solely of Cholecalciferol (Vitamin D3) at a therapeutic high-strength dose of 50,000 IU per capsule, formulated to provide intensive pharmacological support for the correction of profound vitamin D deficiencies.
Instructions for Use / Dosage: For oral administration. Due to the exceptionally high concentration of 50,000 IU, this medication is strictly not intended for daily use. Adults typically take one capsule weekly for six to eight weeks to rapidly correct a documented deficiency, followed by a transition to a lower-dose daily or monthly maintenance regimen as guided by serum calcium and vitamin D monitoring. It should be swallowed whole with water, preferably alongside a meal containing dietary fat to optimise absorption. Always consult the physical package labelling for exact manufacturer dosage guidelines or follow the direct advice of a healthcare professional.
