CoQ10 Cold Weather Product Stability

There is no doubt, that excessive long term exposure to cold, freezing temperatures can be a problem with liquid CoQ10 products. However, cold temperatures, even freezing cold temperatures during shipment will not be a problem -- not desirable but not a problem. The problem could occur with PROLONGED storage/freezing/cold exposure -- and by prolonged we mean more than a week in shipment. We recently, (January 2008), tested a frozen bottle of LiQ-Sorb (170ml bottle) and (after thawing) it returned 100% of its original potency and its dissolution property.

If your liquid CoQ10 is frozen on delivery, thaw it at room temperature, if there are any crystals visible in the liquid CoQ10 you can then immerse the bottle in warm water and shake well before using. Bottom line, the potency of the CoQ10 is not an issue even if it has gone through freezing in the winter.

Long term storage tip: Keep bottle tightly closed and store in a cool, dry place at controlled room temperature 15°-30°C (59°-86°F). Refrigeration is neither necessary nor recommended.
