If you have heart disease or at risk of heart disease the research is very compelling in taking an Omega 3 supplement. Yes you can get Omega 3s from diet but it is not enough. You would have to have quite substantial amounts of nuts and fish daily to get the amount of of Omega 3s to benefit your heart health. Two omega-3 fatty acids that have been associated with heart health benefits, docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), are found in fish oils. The best source for DHA and EPA are fatty coldwater fish such as herring, mackerel, salmon and tuna. Fish oil supplements also can provide omega-3 fatty acids.
There are a lot of supplements to help with your heart health and many types of omega 3s. Be sure that the omega 3s are just that Omega 3s. There are Omega 3-6-9 supplements but we feel you can get enough OMega 6s and 9s in your diet and no need to supplement those. It is the Omega 3s that you want for heart health at most. Be sure that most of the omega 3s consist mostly of DHA and EPA.
The benefits of Omega 3s on your heart health can help your blood pressure, and your cholesterol profile which includes your LDL and triglycerides.
Be sure to supplement with Omega 3s in your diet too. It is just that it is hard to get enough from diet alone, especially if you are having large amounts of fish. You then have to worry about mercury content.
To your succses.
