Applications
Biotin Powder for Supplement Formulations
D-biotin can be used across standalone biotin products, B-complex and multivitamin formulas, and nutritional premixes.
Standalone Biotin Supplements
For capsule, tablet or powder products formulated with biotin as the primary vitamin ingredient.
B-Complex & Multivitamin Formulas
For formulas combining vitamin B7 with other B vitamins, minerals or complementary nutrients.
Nutritional Premixes
For measured vitamin blends intended for downstream supplement and nutrition manufacturing.
Formulation
Working with D-Biotin Powder
Biotin is commonly used at relatively low inclusion levels, making weighing and distribution important considerations in production.
Plan for Consistent Distribution
For larger blends, an appropriate premixing or dilution approach can help distribute the vitamin ingredient more evenly before final blending.
Set the raw-material input according to the finished-product formula and the applicable ingredient specification.
Use a suitable blending sequence when a small quantity of biotin must be dispersed through a larger batch.
Account for the processing requirements of capsules, tablets, powders or premix systems.
Confirm blend uniformity and product stability through the controls established for the final formulation.
