Product Overview
Riboflavin (vitamin B2) is a water-soluble B-vitamin supplied as an intensely yellow-orange crystalline powder – the colour is so characteristic that it doubles as a food colourant (E101) in permitted uses. It is a staple of B-complex, energy and fortification premixes worldwide. VeraVita Bio supplies bulk riboflavin powder for capsule, tablet, gummy and beverage manufacturers.
Key Features
- Industry-standard vitamin B2 source with dual nutrient/colourant identity (E101)
- Water-soluble crystalline powder, intensely yellow – visible at trace levels
- Stable in dry dosage forms; photo-sensitive in solution
- Core component of B-complex, energy and multinutrient premixes
- High-volume commodity vitamin with dependable supply
- COA with assay on request
How It Works
- Nutritional role – riboflavin is an established essential nutrient precursor to FAD/FMN coenzymes; authorised EU nutrition claims exist for the vitamin and belong to the finished label.
- Formulation behaviour – crystalline riboflavin is stable dry but degrades under visible light in solution; beverage and gummy applications need light-protective packaging.
- Colour contribution – its intense yellow makes it useful both as a nutrient and as a natural colour; dose accordingly in white-tablet aesthetics.
- Maximum permitted levels in food supplements vary by market – confirm local caps before finalising formulas.
Typical Applications
- B-complex and multinutrient capsules and tablets
- Energy and sports formulas
- Fortified beverages (with light-protective packaging)
- Gummies and chewables
- Food fortification and colouration (E101 uses)
- Premix manufacturing
