Wild oily fish, such as herring, sardines or mackerel, is a very good source of the valuable unsaturated fatty acids Omega-3 EPA and DHA and of vitamin D. Lean fish, on the other hand (battered fish bites, fish fingers, tilapia and pangasius), hardly contains these important nutrients. Pure Arctic MSC Fish Oil with vitamin D is there for everyone who struggles with oily fish. The daily dose (2.5 ml) (one dessert or coffee spoon) of Pure Arctic Fish Oil contains the Omega-3 fats of (converted) about one whole herring. It has been scientifically proven that this amount of EPA and DHA is good for the heart**, good for your eyesight* (helps you keep seeing sharply) and good for your brain function*. The beneficial effect is obtained with a daily intake of 250 mg of DHA* or 250 mg of EPA/DHA**. These are legally approved health claims. No less than 20% of the fat in our brains consists of Omega-3 DHA; it is an important building block for the brain (just like calcium is for the bones). The vitamin D in the fish oil is important for the maintenance of strong bones and strong teeth. Vitamin D also contributes to a good immune system and plays a role in the maintenance of strong muscles. It has been scientifically proven that EPA and DHA are also good for blood pressure1 and the triglyceride2 (blood fats) level. The beneficial effect is obtained with a daily intake of 3000mg1 and 2000mg2 EPA/DHA. The daily intake of EPA and DHA must then not exceed 5000 mg.
