Our liquid tinctures do not require refrigeration, at all. There is no harm in keeping them in the fridge, if you would prefer to, though this can change the consistency of the liquid and may make it a bit more difficult to dose accurately. The base the herbs are suspended in will protect the potency and quality of the supplement, though it is recommended to store our products away from direct sunlight, in a cupboard or drawer.
The same applies to capsules and/or powders: the ingredients have already been dried and are preserved as part of the manufacturing process. However, if the product contains probiotics, you may like to keep it in the fridge.
