D-Biotin (Vitamin H / Vitamin B7) · High-Potency Biotin for Supplements, Foods & Beverages

Key characteristics

• Chemical name: D-biotin (vitamin H, vitamin B7).
• Form: typically a white or almost white crystalline powder or crystals with no significant odour at use levels.
• Potency & dosage: used at microgram-per-serving levels, requiring carefully designed premixes or trituations for accurate and homogeneous dosing.
• Solubility: sparingly soluble in water; normally introduced via dry premixes, tablets, capsules or specialised liquid systems.
• Stability: generally good in dry, protected systems, with sensitivity to oxidation, light and certain process conditions especially in liquids.
• Function: used to fortify foods, beverages and supplements with vitamin B7, supporting positioning around energy metabolism, macronutrient metabolism and, where permitted, hair, skin and nail health.

Atlas supports customers in premix design, carrier selection and dosage strategy to ensure reliable biotin delivery and label-claim compliance at very low use levels.

Indicative specification points

Final specifications are agreed for each project. Typical food and nutrition-grade D-biotin parameters include:

• Assay: high-purity D-biotin (on dried basis, e.g. within an agreed pharmacopeial range).
• Identification tests: confirm D-biotin structure and purity according to pharmacopeial or food/nutrition-grade methods.
• Specific rotation and related characteristics: monitored to verify the D-isomer and ensure consistent quality.
• Loss on drying: controlled to support powder stability, potency and flow.
• Residue on ignition / sulphated ash: limited in line with specification and regulations.
• Particle size distribution and bulk density: designed to suit premix blending, tableting, encapsulation and powder handling at micro-dose levels.
• Related substances and organic impurities: controlled to meet food, infant and supplement standards.
• Heavy metals and specific contaminants: limited to comply with global and local safety requirements.
• Microbiological profile: aligned with good manufacturing practice, with tighter limits for infant and medical nutrition applications where applicable.

Each batch is supplied with a Certificate of Analysis (COA) and a detailed technical data sheet. Additional documents (GMO status, allergen statements, dietary suitability, contaminants, origin, Halal/Kosher certifications) can be provided from approved producers.

Dietary supplements & beauty-from-within concepts

• Tablets and capsules – D-biotin used alone or in multivitamin, B-complex and “hair, skin & nails” formulas, subject to local maximum levels and claim conditions.
• Gummies, chewables and softgels – biotin incorporated via specialised premixes for convenient, consumer-friendly supplement formats.
• Sublingual tablets, drops and sprays – liquid and orally disintegrating delivery systems designed for targeted biotin supplementation.

Functional foods, cereals & snacks

• Breakfast cereals and cereal bars – D-biotin included within multi-vitamin premixes to support overall nutrient profile and positioning.
• Nutrition and snack bars – products targeting active lifestyle or beauty-from-within concepts, where biotin is combined with proteins, collagen, other vitamins and minerals.
• Bakery products – fortified breads and baked snacks manufactured from premixed flours or vitamin blends, with attention to biotin stability across baking processes.

Fortified beverages & instant powders

• Energy and functional drinks – D-biotin used at low levels together with B-complex vitamins, minerals and functional ingredients.
• Fortified juices and RTD beverages – micro-dose biotin added via premixes, with consideration for pH, light and shelf-life conditions.
• Instant multivitamin and nutrition powders – biotin delivered through multi-vitamin/mineral premixes in sachets, sticks and canisters.

Clinical, infant & specialised nutrition

• Medical and clinical nutrition – D-biotin included as part of multi-nutrient systems in oral nutrition supplements and enteral formulas, within category-specific regulations.
• Infant, follow-on and growing-up formulas – biotin used according to strict compositional and purity specifications defined in local and international legislation.
• Condition-specific products – targeted formulations where biotin contributes to a carefully designed micro-nutrient profile, always within national regulatory limits.

Formulation guidance

• Biotin dosage is driven by:
  • Regulatory minimum and maximum levels for the product category,
  • Desired nutrition and health claims (where permitted),
  • Target consumer group and overall vitamin profile.
• Due to its very low inclusion level, D-biotin is almost always introduced via diluted vitamin premixes or trituations on suitable carriers, to avoid dosing errors and segregation.
• Stability is influenced by temperature, moisture, oxygen, light and matrix interactions; formulation and packaging (e.g. oxygen/light barriers) help preserve biotin levels.
• In complex systems (e.g. beverages, high-temperature processes), it is recommended to validate process and shelf-life losses and, where legally acceptable, adjust overages accordingly.
• Regulatory and nutrition teams must confirm authorised forms, maximum levels, claim conditions and labelling rules in each destination market and product category.

Quality & documentation

• Supplied as food or nutrition-grade D-biotin with agreed specifications for assay, impurities and physical properties.
• Each batch is accompanied by a Certificate of Analysis (COA) and a technical data sheet detailing key analytical parameters and methods.
• Additional documentation can include GMO status, allergen declarations, contaminants and heavy metal data, dietary suitability (e.g. vegetarian/vegan where applicable), BSE/TSE statements, origin and Halal/Kosher certificates, depending on the selected producer and grade.
• Manufacturing sites typically operate under recognised ISO and food safety management systems (e.g. HACCP, FSSC/ISO 22000), with further certifications available on request.
• Customers remain responsible for regulatory compliance, maximum use levels, claims and labelling in each destination market.

Packaging, storage & logistics

• Standard packaging: usually drums or cartons with appropriate inner liners to protect against moisture and light; specific pack sizes for premix makers can be evaluated.
• Suitable for full-container or mixed-container shipments together with other vitamins, sweeteners, minerals and functional ingredients.
• Store in a cool, dry place, away from heat, light and odour-intensive substances to preserve biotin potency and powder quality.
• Typical shelf life is defined in the product specification and on the COA; customers should verify D-biotin retention in their own products via stability and shelf-life studies.
• Shipments can be arranged under FOB, CFR, CIF or other agreed Incoterms, with export, customs and quality documentation coordinated from Ankara, Türkiye.
