Will my dry probiotics in capsules die if I freeze them for a long period of time?, even over a year. I'm talking about the regular capsules of probiotics that are purchased in little bottles to take with every meal.
Friendly bacteria themselves should be fine undergoing the process of freezing, however, I would not recommend freezing the capsules as there is a possibility that the capsules themselves could deteriorate during the freezing & defrosting period. So from my prospects, it's fine to freeze the products which come in powdered sachets (For babies & children, One week flat, and Bifidobacteria & fibre), but I wouldn't recommend freezing the other products in the range.
If you are wondering about freezing live cultures other than those in range, the answer will probably depend on the quality of the live culture strain in question. Freezing yogurt drinks should not damage the live cultures - this process causes the bacteria to enter a dormant state, which is reversible when consumed.
