Vitamin A contributes to ensuring iron metabolism and to the maintenance of normal vision. Vitamin B12 contributes to the function of the immune system, to the normal psychological function, to the reduction of tiredness and fatigue, and contributes to normal red blood cell formation. Vitamin C contributes to the function of the immune system, to the normal psychological function, and contributes to the normal function of the immune system. Vitamin D contributes to the maintenance of healthy bones and teeth and to the normal function of the immune system. The Omega-3 junior syrup contains vitamin D in its natural D3 form (cholecalciferol), which absorbs well into the body. Folate contributes to normal blood formation. Also contributes to the normal psychological function and to the reduction of tiredness and fatigue.

Omega-3 unsaturated fatty acids are important for the synthesis of eicosanoid hormones, which impact reproductive functions, regulate blood clotting, blood pressure and body temperature. They also impact the normal development and function of the brain and nervous system. According to certain guidelines, fat should represent up to 30% of consumed energy, whereby saturated fat should not exceed 10%. Omega-3 also belong to unsaturated fatty acids, which fall among essential fatty acids – which means that the body is unable to synthesise them, and therefore need to be introduced with food. A large dietary source of omega-3 is represented mainly by “fatty” fish, which are however not consumed in sufficient quantities by children.

Omega-3 fatty acids have an indispensable role in the growth and development of children's nervous system, brain tissue and vision, particularly in the last three months of pregnancy and first years of the child’s development. This is why the need for omega-3 fatty acids, which have also a significant impact on the heart and nervous system, is increased in that period of time. People consume 77% less fish, which are a source of omega-3 fatty acids, than what is recommended. The recommended daily dose for children aged 2 to 18 is the same as for the adult population, i.e. eating fatty fish once to twice a week. Since a sufficient quantity of omega-3 fatty acids cannot be ensured through food, fish oil may be added to meals of children, which they often do not like due to its unpleasant smell and taste.

Omega-3 fatty acids fall among essential fatty acids, which means that our body is unable to synthesise them and must be consumed through food. There are 3 type of omega-3 fatty acids: ALA, EPA and DHA. Our body must first convert ALA fatty acid into EPA and DHA; however, this conversion is very inefficient, since it converts only a very low percentage. The most important step in endogenous synthesis is the conversion of EPA into DHA, which is considerably impacted by the intake of EPA and DHA through food. DHA may also be synthesised from EPA, which is consumed with seafood, through the same biochemical process. For this reason, vegetable oils, rich with omega-3 (with ALA), are not the best choice for replacing omega-3 fatty acids. Age and gender also affect conversion to a considerable extent.
