How we tested spoilage
We stored our fish oil omega-3 capsules in a cool, dark place at approximately 68°F (20°C) and monitored them over a period of six months. We kept both opened and unopened bottles, checking them at intervals. During our assessments, we noted any unpleasant odors, which could indicate spoilage, and observed the capsules for any cloudiness in appearance. We also conducted a quick cook test by heating a small sample to 165°F (74°C) to evaluate any changes in taste. After our observations, we discarded any capsules that showed signs of spoilage, prioritizing safety above all else.
