Formulation
Working with Riboflavin Powder in Formulations
Particle size, light exposure and water solubility can influence how Riboflavin powder is handled in different finished-product formats.
Dry Blending
The documented particle-size requirement can support dispersion and blend-uniformity planning in tablets, capsules and dry premixes.
Light Protection
Riboflavin is light-sensitive, so formulation development, processing and packaging should consider exposure to light.
Water Solubility & Dispersion
Riboflavin has relatively low water solubility compared with many other water-soluble vitamins. For beverage, liquid or high-uniformity systems, formulators should evaluate dispersion, dissolution conditions and the effect of the complete formulation rather than assuming rapid dissolution from the Vitamin B2 classification alone.
Finished-Product Format
Dosage, excipients and processing conditions should be considered for the intended tablet, capsule, premix or other finished-product format.
Applications
Riboflavin Powder for Supplements & Vitamin Premixes
Common uses include solid-dose supplements, multivitamin and B-complex formulas, and nutritional premixes.

Multivitamin & B-Complex
Suitable for multivitamin and B-complex formulations that use Riboflavin as the Vitamin B2 ingredient.
