Your question has insufficient info. Typically, 600 mg fish oil per day is not harmful. But you are not specifying what fish, nor the EPA/DHA content.
That's not a high dose, but the above is correct in noting that not all fish oil is created equal.
Hi, Sorry to mention this.
Fish Oil Concentrate 600mg
Omega-3 fatty acid 300mg
EPA 162mg
DHA 108mg
Thanks
