I don't know for sure, but I think the brand you are taking isn't fish oil, but isn't it krill oil? You might try taking a good fish oil tablet, 2000 grams daily... that's what I take.
Your total cholesterol is high, but so is your HDL - the good cholesterol. Have both the LDL and HDL gone up, or just the HDL? If so the MegaRed is doing what it does best, raise the good cholesterol.
If I had your cholesterol test, I would mix in a Statin.
