Fish oils are crucial for the good health of your heart and brain – and they can even make you happier! These substances, full of omega-3 fatty acids, can improve your heart’s health and reduce your risk of memory loss and Alzheimer’s disease, and they appear to ease depression.
For maximum benefit, eat one to two servings of fatty fish (mackerel, herring, salmon, and tuna are good choices) a week, or take 1 gram daily of fish-oil supplements that contain EPA (eicosapentaenoic acid) and DHA (docosalhexanoic acid). Do not consume more than two servings a week o fatty fish, to avoid ingesting dangerous levels of mercury and other contaminants.

thanks very good
Using pharmaceutical-grade fish oils may limit your exposure to contaminants, such as mercury, dioxins and PCB’s. Pharmaceutical-grade fish oils provide a minimum amount of omega 3 fatty acids and must adhere to specific manufacturing procedures. These will provide your best source of clean omega 3 fats without increasing your exposure to toxins and mercury found in fresh fish.
