Shelf life and protection

What happens after opening and which packaging determines the progression.

1. 1What happens to omega-3 after the pack is opened?Once opened, the oil is exposed to oxygen and light. Oxidation values rise from that moment on — regardless of how good the value was at the time of filling.Shelf life & protection
2. 2Bottle, blister or sachet — what protects omega-3 better?The less often the oil comes into contact with air after first opening, the more slowly the oxidation state rises. An individually sealed portion is opened exactly once and then fully consumed.Shelf life & protection
3. 3How are heavy metals, PCB and dioxins assessed in fish oil?These substances are analytically tested as contaminants and set against the applicable maximum levels. Missing disclosures do not mean no contaminants are present — they mean nothing was published.Analytics & oxidation
