While probiotics are sensitive to changes in environment, humidity tends to be more important than temperature when it comes to their survival.
When stored in a fridge, probiotics are likely to be subject to constant changes in temperature and humidity whenever the fridge is opened and closed. This may cause dew condensation, exposing the probiotics to humidity and reducing their effectiveness. Meanwhile, storing probiotics in dry, cool places can keep the probiotics active without the need for a fridge.
Probiotics Protocol is designed to protect its probiotics from sudden and rapid changes in temperature and humidity through the application of special solutions such as CSP’s Activ-Vial probiotic packaging to keep your cat’s supplements safe and secure without needing to rely on a fridge.
Just make sure to store them somewhere free from direct light and humidity!
