Probiotic bacteria themselves should be fine undergoing the process of freezing, however for the OptiBac Probiotics range we would not recommend freezing the capsules as there is a possibility that the capsules themselves could deteriorate during the freezing & defrosting period.

So from our range, it's fine to freeze the products which come in powdered sachets (For your child's health, For a flat stomach, and For maintaining regularity), but we wouldn't recommend freezing the other products in the range.

If you are wondering about freezing probiotics other than those in our range, the answer will probably depend on the quality of the probiotic strain in question. Incidentally, freezing 'prebiotics' (the food source for your probiotics) should always be fine, as these tend to be more hardy than probiotics.
