Body heart & brain supportOmega-3 fatty acids
Omega-3 fatty acids
- Are good for the heart, resistance, joints (reduce inflammation), eyes, skin and brain
- Are not created by the human body
- Must be taken through the diet (oily fish, walnuts, linseed) or a dietary supplement
- EPA, DHA and alpha-linolenic acid are the most important omega-3 fatty acids.
- We eat too many omega-6 fats and too little omega-3 fatty acids
Heart and blood vessels
The positive effect of omega-3 fatty acids on heart, blood vessels, cholesterol, triglycerides and high blood pressure has been demonstrated in clinical studies. Therefore, several official health authorities recommend eating fish at least twice a week. Especially fatty fish such as salmon, mackerel, herring, sardines and albacore are a rich source of omega-3 fatty acids.

Double-blind placebo-controlled research shows that fish oil rich in EPA and DHA has a beneficial effect on joint function, modulates cartilage degradation and is better than placebo. This is probably due to the inhibitory effect of EPA and DHA from fish oil on inflammation factors such as COX enzymes and interleukins.

Eyes & brains
Omega-3 fatty acids support the normal functioning of the eyes and brain. Studies in humans show that omega-3 fatty acids from fish oil promote recovery after eye surgery. Omega-3 fatty acids also alleviate the symptoms of dry eyes due to intense screen use (TV, computer, tablet, smartphone).
The effects of EPA or DHA, two omega-3 fatty acids from fish oil, on the functioning of the brain have been thoroughly investigated in dozens of studies. In general, we find that EPA and DHA positively influence the health of the brain (e.g. concentration, behaviour).
