Vitamin D₃ is known to be sensitive to oxidation by air. Loss of activity is further accelerated by heat and exposure to light. Vitamin D₃ in our Hansevit^®  D₃ 500 is embedded in a matrix of gelatin and carbohydrates, stabilized with antioxidants – an additional flow aid ensures good flowability. Thanks to ZMC´s unique micro-encapsulation technology the tailored addition of nature-like antioxidants ensures the highest possible protection against oxidation of the active substance. Proven protection – without use of synthetic antioxidants like BHT and BHA.
