We recommend that you consume your liposomal products within 40 days of opening for maximum potency and longevity. If you are concerned about using your product within this time frame, please note that your product should not go rancid after 40 days when stored at normal conditions, however it will slowly begin to degrade as soon as it is opened, as with any nutrient exposed to temperature, light and air changes.
As with any vulnerable nutrient, degradation over time is normal, so the goal is to keep the nutrient at a consistent, cool temperature. We recommend refrigeration during this time to prevent degradation and maximize potency. If you are traveling, and you choose to take your liposomal product with you, it should be fine if kept at normal room temperature, or high temperature only for short periods of time (please see this article here: Can my liposomal be exposed to very hot or cold temperatures?. It is personal preference as whether to take the product with you, as its rate of degradation will depend upon your travel destination and route. Other factors that may increase degradation include exposing the liquid to air and light frequently, such as opening the bottle.
Note: Unopened liposomal products typically retain potency and freshness for about 1 year from the "made date" under good storage conditions. You can find the “made” date of this product located on the bottom of the bottle.
