How we tested spoilage

We stored our Calcium Carbonate Chewables in a cool, dark pantry at around 68°F (20°C) and held both opened and unopened samples for 90 days past their expiration date. During this period, we carefully observed each sample for any changes in color or odor, noting any unusual textures that might indicate spoilage. We also conducted a quick cook test by heating a sample to 165°F (74°C) to verify its integrity, but found no significant changes. Ultimately, prioritizing safety, we discarded any chewables that exhibited questionable characteristics, ensuring our health remained uncompromised.
