How should the probiotic be stored, and does this affect its effectiveness?

Probiotics contain live microorganisms, and storage conditions directly affect their viability. For this product the instructions are: store in a cool, dry place out of the reach of children, and do not use if the packaging is damaged. In addition, there are general rules that apply to most probiotics in capsules:

• Temperature. Avoid storing them in hot places — next to the cooker, on a windowsill in direct sunlight or in a car in summer. Heat speeds up the death of the bacteria.
• Humidity. The bathroom is not the best place to keep supplements: fluctuations in humidity and temperature have a negative effect on capsules. A dry place is preferable.
• Expiry date. Probiotics lose activity over time even when stored correctly. Check the date on the packaging and do not use the product once it has passed.

Some probiotics need to be kept in the refrigerator, while others are stable at room temperature — this depends on the specific strain and the manufacturing technology. Check the storage conditions on the label or in the instructions for this product.
