I take fish oil as well. That’s actually the only polyunsaturate oil in liquid form that I consume intentionally because the benefits are well known. High quality stuff that’s IFOS certified is getting prohibitively expensive though.
I get Carlson’s Labs lemon liquid fish oil. Sometimes Costco super strength fish oil capsules. I read its good for the cardiovascular system and for fatty liver disease. My parents take it with Glucosamine for arthritis pain. Their Dr approved. I also read that fish oil reduces triglycerides.
