You have probably been hearing a lot about fish oil, fish oil capsules and Omega-3's. These are vitamins and minerals that are primarily found in Mediterranean diets, which are thought to be responsible for healthy hearts and a great functioning digestive system.
Most importantly, those who eat primarily "Americanized" diets tend to take in too much omega-6 polyunsaturated fatty acids but not enough omega-3 polyunsaturated fatty acids (found in fish and fatty mammals). Which is a recipe for heart disaster.
But how do you get just the right amount of Omega-3's? It's easy if you take it in pill form. I buy mine from Life Extension Vitamins website, where for around $27 you can buy a bottle of 60 capsules, which should last you about a month (taking two each day).
