Keep BioSil capsules and drops:
- at room temperature (that means storing it in the refrigerator is not necessary, but it won't harm the ingredients' effectiveness)
- dry (if BioSil gets in contact with moisture or water, it deforms)
If you preserve BioSil as indicated above, you can keep BioSil capsules for 2 years and BioSil drops for 3 years, even if the packaging has already been opened. The date (month and year) printed on the bottle indicates when the BioSil product becomes ineffective.
