Bottle, blister or sachet — what protects omega-3 better?
Direct answer
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.
The packaging determines how often the oil is exposed to ambient air.

The difference lies in handling
A bottle is opened as many times as portions are taken. At two portions a day that is a double exposure — every day.
Packaging formats compared
| Bottle | opened at every use, remaining volume partly filled |
|---|---|
| Blister | individual capsules removable, the rest stays protected |
| Sachet | sealed until use, then fully consumed |
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 applies regardless
Regardless of the format: store cool, dry and dark. Light and heat accelerate degradation in any packaging.
The MVS choice
MVS seals portions individually so that protection is maintained until consumption.
