It's a lot. It's more than just the mg amount, it's the mg of fish body oils, epa and dha per pill. Some have higher concentrations than others. I use the trader joe's brand, which actually has a higher concentration than most, even the fancy swanson fish oil.
My pills are 500mg, with a fish body oil of 1100mg. Of that, the EPA is 300mg, and the DHA is 200. I take about six of those pills. Because of the higher concentration, I can take less. Normally you want to take around nine. Best to ask your doctor, though.
