Please see the instructions on the back of each pouch on how to store each product.  We advise you store this in a cool, dark and dry place away from sunlight.  We haven't frozen our Pea Protein powder to see how well this freezes and also what impact it would have on the nutritional value, we  therefore recommend you do not do this, unless your own research indicates that it will not have any detrimental impact on the product.
