There is no need to keep LYMA capsules in the fridge. LYMA’s solid copper storage vessel keeps the capsules stable at room temperature (below 77 degrees F). Or if you’re on the go, you can use the resealable pouch to store your LYMA capsules. It should be kept out of reach of children and it should not be displayed in direct sunlight or close to heat sources such as radiators, cookers, or under strong lights.
