Like any other supplement, Ojai Energetics Full-Spectrum Hemp Elixir can expire and has an estimated shelf life of one year opened and two years unopened. After this period, the elixir will lose some of its potency. Refrigeration is optional—nothing will happen to the elixir if you do or don’t chill it. With regular use, a bottle of our hemp elixir will last about a month for optimal endocannabinoid system health.
