Vitamin D3

Vitamin D3, or cholecalciferol, is a fat-soluble vitamin of the secosteroid family, supplied by Nustras as a white crystalline powder. Because finished products need only very small amounts, it is normally incorporated through oil solutions or dry powder concentrates on a carrier.

It is formulated into vitamin D supplements, multivitamins, softgels, drops, tablets and gummies, into fortified milk, plant-based beverages, cereals and spreads, and into vitamin premixes for food and animal feed.

The material is a white to off-white crystalline powder, practically insoluble in water and soluble in oils and alcohol; it is sensitive to light, heat and oxygen. CAS number 67-97-0, molecular formula C27H44O, molecular weight 384.6. Identity is confirmed by infrared spectroscopy and assay by HPLC, both standardised to specification; heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies vitamin D3 in bulk commercial quantities, in sealed nitrogen-flushed packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Cholecalciferol is a permitted form of vitamin D in major supplement and food-fortification markets; buyers confirm the concentration, grade and permitted level for their application.
