Vitamin D3 Crystalline 40 Million IU/g

Product Overview

Cholecalciferol crystalline is vitamin D3 at its highest commercial concentration – 40,000,000 IU/g (1 mg ≈ 40,000 IU). This is a raw material for premix houses and manufacturers who dilute it to their own working concentrations, not a finished-goods grade. VeraVita Bio supplies D3 crystalline in bulk with full handling documentation; diluted powder grades (100,000 IU/g and below) are available on request.

Key Features

• 40,000,000 IU/g crystalline cholecalciferol – maximum-concentration grade
• For premix houses and dilution-capable manufacturers
• Diluted standard grades (e.g. 100,000 IU/g on carrier) available on request
• Fat-soluble vitamin with well-defined stability behaviour
• One of the highest-volume vitamins globally – dependable supply
• COA and safety documentation on request

How It Works

• Potency maths – 1 µg cholecalciferol = 40 IU, so the crystalline grade delivers 40,000,000 IU per gram; dilution grades exist precisely because this concentration is impractical to dose directly.
• Handling discipline – at this potency, accurate weighing, validated scales and trained operators are mandatory; overdose risk in formulation is real and must be engineered out.
• Formulation role – the source material behind D3-fortified foods, supplements and premixes worldwide; the vitamin itself has authorised EU claims that belong to the finished label.
• Regulatory note: maximum vitamin D levels in food supplements are capped in several EU markets – confirm local limits before formulation.

Typical Applications

• Premix manufacturing (as dilution raw material)
• High-dose D3 supplements (producer-diluted)
• Food fortification (dairy, cereals, beverages)
• K2 + D3 combination products (diluted grades)
• Vitamin dilution houses and contract manufacturers
