What Is Vitamin H Powder?
The actual scientific name of the substance is D-Biotin or Vitamin B7. It is a water-soluble coenzyme necessary for the synthesis of fatty acids, amino acid metabolism, and cellular energy generation. Our product has a specific rotation of +89° to +93° according to USP/EP pharmacopeia criteria which confirms 100% D-isomer purity which is the only physiologically active form.
The crystalline structure provides excellent thermal stability (>230°C melting point), making it ideal for high temperature processing in tablet compression and extrusion applications. While racemic DL-Biotin mixes are only 50% effective, our pure substance ensures 100% bioavailability in formulations.

Functions
This coenzyme has important functions in several metabolic processes. Strengthens the keratin framework in hair and nails to improve structural stability. It participates in gluconeogenesis . It supports a steady blood sugar homeostasis in carbohydrate metabolism .
Enhances dermal collagen network for cosmetic purposes. In animal nutrition, it enhances hoof quality in animals and feather growth in poultry. It also serves as a necessary cofactor in the enzyme systems of propionyl-CoA carboxylase and acetyl-CoA carboxylase.
Application Fields
Nutraceuticals Solid Dosage
Our 99% pure grade gives you outstanding flowability in high speed rotary presses. The particle size dispersion (40-100 mesh) avoids problems of content consistency in tablets and hard-shell capsules. The powder is resistant to compressive forces without any capping or lamination flaws.
Functional Food & Beverage Fortification
For dairy and beverage applications requiring cold-water solubility, we offer CWS-grade formulations. These maintain stability during pasteurization cycles and low-pH environments in juice matrices without causing oil separation or ringing.
Animal Feed Premixes
Feed-grade product incorporates cross-linked coating technology to preserve >95% potency during steam pelleting processes. It remains chemically inert when blended with trace minerals in compound feed formulations.
Cosmetic Raw Materials
Our pharmaceutical grade substance is used in high-concentrate serums and scalp treatments when volume constraints need the highest density of active ingredients per milliliter.

FAQ
Q: What is the difference between 1% or 2% Biotin and Pure product?
A: Pure powder (>98%) suitable for medicines and high-concentrate cosmetics. The 1%-2% level versions are triturations on carriers such as maltodextrin for use in animal feed or supplements for microgram level weighing and homogenous mixing.
Q: How does it function when processed under high temperature?
A: Pure D-Biotin is stable with melting point over 230°C. For lengthy periods of extrusion with moisture/pressure, we propose spray-dried forms for potency after processing at >95%.
Q: Is your product suitable for vegan formulations?
A: Yes. Our material uses chemical synthesis from fumaric acid, making it vegan-friendly. Non-animal origin statements are provided upon request for certification compliance.
Q: Why is Specific Rotation critical?
A: It confirms 100% D-Biotin content. DL-Biotin has only 50% activity. Deviation from +89° to +93° indicates inactive isomers, reducing efficacy.
Q: What storage prevents caking?
A: Store sealed below 25°C at <60% relative humidity in aluminum foil bags or lined drums. Maltodextrin carriers in diluted grades are hygroscopic—proper sealing prevents agglomeration.
