What happens to omega-3 after the pack is opened?
Direct answer
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.
The quality of a product is not a state but a progression.

The moment of opening
Until opening, the packaging determines what happens to the oil. After that, handling decides how quickly the oxidation state rises.
Three influences after opening
Oxygen
Every contact accelerates oxidation
Light
Accelerates degradation further
Temperature
Heat acts as an amplifier
The MVS quality chain
Select, process, verify, protect — as one continuous chain.
Select
Raw material, origin and specification are defined and documented before processing.
Process
Concentration, molecular form and purification steps determine the later quality.
Verify
Analytics on the finished product — not only a certificate for the raw material.
Protect
Capsule, packaging and portioning protect the oil until it is taken.
What accelerates degradation
- Leaving a bottle open for extended periods
- Storing capsules in an open container
- Heat, for example above a radiator or in a car
- Taking portions with damp hands
Why the packaging format matters
A bottle is opened at every use. An individually sealed portion is opened immediately before use and then fully consumed.
Protection as part of the concept
MVS treats the protection of the individual portion as part of the quality chain — not as a packaging detail.
