FAQ
Q1: What is the difference between natural and synthetic Vitamin E?
A: Natural Vitamin E (d-alpha-tocopherol) has approximately twice the bioavailability of synthetic Vitamin E (dl-alpha-tocopherol) due to stereoisomer recognition by biological systems. Our natural form demonstrates superior tissue retention and biological activity.
Q2: Why choose powder form over oil form for formulations?
A: Powdered Vitamin E offers superior stability, easier handling in manufacturing, better compatibility with dry mixes, and precise dosing accuracy compared to oil forms, while maintaining equivalent bioavailability through our advanced microencapsulation.
Q3: What is the recommended dosage for formulation?
A: Clinical studies show efficacy at 100-400 IU daily for general antioxidant support. We provide technical guidance for optimal dosing based on specific health targets and population needs.
Q4: How stable is your Vitamin E powder in final products?
A: Our microencapsulated powder maintains ≥95% potency for 24 months when stored properly. We recommend protective packaging and avoidance of high-heat processing to maximize stability.
Q5: Can your Vitamin E powder be used in aqueous systems?
A: Yes, our instantized formulation is specifically designed for excellent dispersibility in water-based systems, making it ideal for beverage and instant drink applications.
