FAQ ： Ascorbic Acid

Q1: What is the difference between vitamin D3 and vitamin D2?

A1: Vitamin D3 (cholecalciferol) is the form synthesized in human skin and is commonly derived from lanolin, while vitamin D2 (ergocalciferol) is plant-derived. Vitamin D3 is widely regarded as more effective at raising and maintaining blood levels of 25-hydroxyvitamin D, and it is the preferred form in most supplements and fortified foods.

Q2: Why choose the 100,000 IU/g powder form?

A2: The standardized powder enables precise, low-dose addition with excellent blending uniformity. Compared with handling the highly potent crystalline form, it is safer and easier to process, and it is ideal for tablets, capsules, sachets and fortified food applications.

Q3: What is the MOQ and delivery time?

A3: The MOQ is 500 kg, and preferential pricing is available for bulk orders (≥ 1,000 kg). Delivery time is 2–3 weeks after order confirmation, with on-time delivery guaranteed for large orders.

Q4: How should vitamin D3 powder be stored?

A4: Vitamin D3 is sensitive to light, air and heat. Store the product in sealed, light-protected packaging in a cool, dry place. Under recommended storage conditions, it maintains its potency within specification throughout the stated shelf life.
