What do omega 3 fatty acids do?

Some omega-3 fatty acids are essential for humans. This means that they cannot be produced by the human organism itself. All other required omega 3 fatty acids can then be produced from them. However, the conversion rate is sometimes rather low, which is why it is advisable to also supply non-essential fatty acids such as DHA and EPA via the diet or food supplements.
The fatty acid DHA is most concentrated in the brain and the retina. EPA is a precursor substance for eicosanoids, which play a role in the immune system, blood clotting and the regulation of blood pressure and heart rate. The following health claims have been scientifically proven to be true:
- DHA contributes to the maintenance of normal brain function
- DHA contributes to the maintenance of normal vision
- EPA and DHA contribute to normal heart function
- DHA intake by the mother contributes to normal brain development in the fetus and breastfed infant
- DHA intake by the mother contributes to normal eye development in the fetus and breastfed infant
- DHA intake contributes to the normal development of vision in infants up to 12 months of age
- 3g (8.33 ml algae oil) DHA and EPA contribute to the maintenance of normal blood pressure. No more than 5 g of DHA and EPA should be consumed.
- 2g (5.5 ml algae oil) DHA contributes to the maintenance of normal blood triglyceride levels. No more than 5 g of DHA and EPA should be exceeded.
