Easy Health Inc. has more than 11 years experience in natural health products and provides D-biotin Powder (pharmaceutical grade) with confirmed test 99.0-100.5%. Specific rotation of +89° to +93° indicates 100% physiologically active stereoisomer content, unlike racemic mixtures where only ½ is effective. Strictly controlled to assure loss on drying ≤1.0% and heavy metals within international standards (Pb ≤2.0 ppm, As ≤1.0 ppm). ISO, Halal, Kosher, FDA and USDA Organic certificates. The crystalline shape is strong at processing temperatures up to 2 hundred°C and so may be utilized in food fortification, nutritional dietary supplements and beauty packages requiring long-term balance.
Vitamin H, commonly known as Coenzyme R, is the naturally occurring, metabolically active version of Vitamin B7. Unlike synthetic DL-biotin, our product offers pure D-isomer effectiveness with just 50% active molecules.
This water-soluble vitamin acts as an important cofactor for carboxylase enzymes. These enzymes are used in the synthesis of fatty acids, breakdown of amino acids, and the creation of glucose. Biotin helps keep metabolic pathways running. Without enough biotin, energy levels and cellular health are affected .
The product will be essential for developing high performance supplements. Its crystalline structure guarantees homogeneous dispersion in premixes. The powder is highly soluble in dilute alkali solutions, making it easier to make aqueous formulations for beverages and liquid vitamins.

Mastering Metabolism
D-biotin is an essential coenzyme in the carboxylase processes. This allows your consumers' cells to make fatty acids, break down amino acids and make glucose efficiently. This metabolism assistance provides energy and cell vitality for a long time.
Beauty from Within
Credibility in beauty and health products comes from verified biotin effects. Clinical trials have found that biotin builds keratin infrastructure, leading to fuller hair, more resilient nails, and better skin hydration. Compatible with aqueous and emulsion systems, which is highly valued by cosmetic formulators.
Processing Stability
This crystalline structure remains intact throughout the steps of tablet compression, encapsulation and baking. Potency is stable up to 200°C so you can reliably make fortified foods and supplements. This thermal resilience helps to cut reformulation expenses and improves product shelf life to 36 months.
Regulatory Certainty
Our D-biotin Powder meets the food, supplement and pharmaceutical standards in China, EU, USA and other international markets. Pre-approved status speeds your product registration deadlines and decreases compliance documentation burden.

Dietary Supplements
Increase hair pores and skin nail complexes, b nutrition complexes and prenatal nutrients with specific microgram dose. The small particle length (ninety five% to eighty mesh) assures homogeneous content material in drugs and drugs.
Food Fortification
Fortify functional beverages, infant formula, protein bars and breakfast cereals . Powder is stable during extrusion and UHT processing to preserve declared label claims over shelf life.
Cosmetics & Toiletries.
Add to shampoos, conditioners, serums and lotions for hair electricity and scalp health. Pre-dissolve in aqueous section or use with permitted solubilizers to optimise bioavailability.
Animal Nutrition
Support hoof health in dairy cattle Prevent fatty liver syndrome in poultry Improve reproductive function in swine The heat-stable version survives pelleting temperatures without loss of effectiveness.

Each batch is rigorously tested by HPLC and the assay is verified to be in the region of 99.0-100.5%. Our ISO certified factory utilises HACCP standards from raw material receipt to final packaging. Heavy metal limitations and microbiological safety are verified by third-party testing before shipment.
Each order includes full traceability documents. You're provided with Certificates of Analysis, stability data and regulatory support files that make your quality audits easier. Our R&D team provides formulation expertise to help you optimise dose levels and ingredient interactions.


Q: What is the difference between D-biotin and DL-biotin?
A: D-biotin is the natural physiologically active version of biotin. DL-biotin is a racemic combination with only 50% active D-form. 99% pure D-biotin is contained in this product.
Q: How is it stored?
A: Keep in a well sealed container in a cool, dry area away from light and moisture. Vacuum-sealed packing is recommended for best stability for long-term storage.
Q: Is it heat stable for baking and extrusion?
A: Yes it is normally stable under regular food processing temperatures. Some loss of potency can occur at temperatures above 200°C or with extended exposure to high heat, hence process validation is recommended.
A: How long do they usually last?
A: 36 months when sealed and stored under recommended circumstances for long term formulation integrity.
Q: How much should I take?
A: 30-100 µg/day (supplements for people); 0.1-0.5 mg/kg (animal feed). Local regulatory constraints for food fortification applications should always be observed.
Q: Can it be used for vegetarian and vegan products?
A: Yes, it is synthetically created and 100% devoid of animal derived elements. It is ideal for vegetarian and vegan formulations.
Q: Is there any solubility problem in formulations?
A: Slightly soluble in water (0.02g/100ml). Warm water pre-dissolve or use with authorised solubilizers for aqueous systems. The powder is stable in alkaline medium.
Q: Are there recognised interactions for stability?
A: Do not mix with strong oxidizers, acids or raw egg whites (avidin in the egg whites will bind biotin) When properly manufactured, it is compatible with most vitamins and minerals in premixes.
