That will never work for LDL! If you want to take any type of fish oil for LDL or triglycerides, get your Dr. to prescribe Lovaza (which is now available in generic). Its a high quality prescription fish oil used to lower triglycerides and lower LDL. Adding this to my regime lowered cholesterol by 50 in less than a month! It also dramatically reduces triglycerides. Otherwise, the other fish oils may be good for the heart in general (maybe, depending on brand and dosage - they're all kind of sketchy and marketed as wonder drugs but too low in potency for any real benefits), but this Rx is designed to do what you are looking for!
It's nothing more than a very, very low dose natural statin. you may want to get on the real thing.
