Frequently Asked Questions for Formulation Engineers & Buyers
Direct answers to common procurement, compressibility, solubility, and quality assurance queries.
What is the difference between Vitamin D3 100 CWD Powder and Vitamin D3 500 DC Beadlets?
Vitamin D3 100 CWD (100,000 IU/g) is a fine microencapsulated powder engineered to disperse rapidly in cold water, making it ideal for effervescent tablets, chewables, and drink mixes. Vitamin D3 500 DC (500,000 IU/g) consists of denser, free-flowing spherical micro-beadlets designed specifically for direct compression swallowable tablets, where high active potency and low volumetric usage are required to avoid bulk volume expansion.
How does microencapsulation protect Vitamin D3 during high-speed compression tableting?
Cholecalciferol is inherently sensitive to oxygen, light, and mechanical shear. Our microencapsulation process embeds the active lipophilic vitamin inside a protective protective matrix (such as food starch, gelatin, or gum arabic) stabilized with antioxidants like alpha-tocopherol or sodium ascorbate. This protective coat withstands compression forces up to 25 kN on rotary presses without fracturing the inner core or triggering potency loss.
Can you provide plant-based or vegan Vitamin D3 for organic certified formulations?
Yes. While conventional D3 is derived from lanolin (sheep’s wool grease), Xi'an Le-Nutra manufactures a 100% plant-sourced Lichen-derived Vitamin D3. It is fully certified Non-GMO, vegan, and free from animal-derived gelatin or allergens, allowing European and North American brands to meet clean-label, vegan, and organic market positioning.
What excipients work best with your DC Grade Vitamin D3 micro-beadlets?
Our DC grade beadlets exhibit exceptional flowability and segregation resistance when combined with Microcrystalline Cellulose (e.g., MCC PH-102 or PH-200), Dicalcium Phosphate (DCP), and directly compressible Lactose Monohydrate. For lubrication, low-shear additions of Magnesium Stearate or Sodium Stearyl Fumarate (0.5% – 1.0%) are recommended to ensure clean punch ejection.
What is the standard lead time and minimum order quantity (MOQ) for custom ingredient batches?
Standard inventory grades (such as D3 100 CWD and 500 DC) carry an MOQ of 25 kg (standard fiber drum) with immediate air or ocean dispatch within 3-5 business days. Custom particle size mesh cuts, specialized matrix shell formulations, or co-granulated D3+K2 premixes carry an MOQ of 100 kg with an expedited production turnaround of 10-14 days.
How does Xi'an Le-Nutra support global regulatory filings and quality audits?
We provide full technical dossier packages including DMF documentation, CEP statements where applicable, US FDA GRAS notices, allergen-free certificates, GMO-free statements, BSE/TSE-free declarations, and third-party heavy metal / pesticide screening reports.
