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. A lot of the fish prepared for children (battered fish bites, fish fingers, tilapia and pangasius) is lean fish and hardly contains these important nutrients. The Brain Building Blocks Kids contains Pure Arctic MSC Fish Oil with vitamin D and is there for everyone who struggles with oily fish. One dessert / coffee spoon of Pure Arctic Fish Oil contains the Omega-3 fats of (converted) more than half a 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 your children 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. Research has shown that many children of colour have a vitamin D deficiency. Especially during the winter months and in spring, taking extra vitamin D (for example in fish oil) is recommended for your child. More and more children with white skin also have too little vitamin D. On the one hand, less fish is being eaten; on the other hand, children play indoors more, so the skin gets less sunlight.
