- cardioprotective.
Consumption of oily fish can help protect against cardiovascular disease, preserving arteries and heart even during periods of high stress. Fish oil may offer protection from senile dementia by counteracting neuroinflammation and neuronal death of brain cells. Consuming oily fish can also protect against oral and skin cancers.

As for the dosage recommended by experts, however, it is 1-5 g per day. , to be taken preferably with meals. Generally they are prescribed as follows: 5 g per day for the treatment of lipidemic and cardiovascular metabolic decompensations, therefore in the presence of high cholestrol and triglyceride levels; 3 g per day for the management of inflammatory diseases, 1 g per day for the prevention of oxidative damage. .
