What kind of fish oil and EPA do you take? They vary a lot in their source, and I have not been able to digest any of them in the past. My digestion is good, as long as I stick to the diet which I've found to work over many years. But sometimes one would like to add something new. I wonder what is a safe source of fish oil? Fish are widely toxic today, due to toxins in the waters of several kinds. I cannot eat ANY fish without hearing about how I have made a mistake, from my digestive system. And yet, if I stick to my diet, I have almost no digestive disturbance.
