Product Description:

Cholecalciferol is vitamin D3, the form the skin makes in sunlight. The liver and kidney convert it to calcitriol, the hormone that governs how the body handles calcium and phosphate. This page covers tablets and capsules of 1,000, 2,000, 5,000 and 50,000 IU; 40 IU equals one microgram. Softgels carry the vitamin dissolved in oil, while tablets use a dry, stabilised powder. Most D3 is made from lanolin from sheep wool, and lichen-derived D3 serves vegan ranges.

Strengths of 1,000 to 2,000 IU are usually sold as food supplements for daily intake, with the amount set by the label. Products of 50,000 IU are registered as prescription medicines in many markets, taken weekly or less often under medical supervision for diagnosed deficiency, and 5,000 IU may fall either side depending on the country. Regulators set tolerable upper intake levels, so permitted supplement strengths vary. Vitamin D is fat-soluble and absorbed well with a meal. With high doses, pharmacists check calcium levels and thiazide use.

Sourcing notes. First agree the regulatory category of each strength in the destination, because it decides between a CTD or ACTD dossier and a supplement notification. Cholecalciferol is sensitive to light, heat and oxygen, so ask how overage is set and request zone IVb stability data for hot humid markets. Ask for a CoA per batch with assay against label claim, content uniformity, heavy metals and microbial limits, and raw material meeting the USP or Ph. Eur. monograph. State strength, tablet or softgel, D3 source, gelatin type and any halal need.
