In order to preserve nutritional value and high potency of the Fresh Royal Jelly it needs to be kept frozen. However, it is safe to keep the monthly supply of Fresh Royal Jelly in refrigerator. When you purchase the more economical large container of our Fresh Royal Jelly transfer the amount of Royal Jelly which you plan to use, within a month, into a smaller container and keep it in the refrigerator. Freeze the rest of the Royal Jelly for later use. Then, when you need another monthly supply, just defrost it in the refrigerator for a day or two, transfer again the amount you plan to use within a month into a smaller container and freeze the rest.
