Once you open a bottle of liquid fish oil or capsules, the content will be exposed to air and this will initiate oxidation of the product. The ConCordix Smart Chews are individually sealed in aluminium blisters, providing a protective barrier against oxygen, humidity and light. This ensures a fresh, high-quality product every day. Consuming one Smart Chew, will not expose the remaining dosages in the blister to oxygen. During production of ConCordix Smart Chews, we avoid oxidation of the fish oil through a closed production unit operating under inert conditions.
