the lower the level is the better i'm told it should be around 4 when i was put on cholestrol lowering drugs some 35 years ago my levels were around 25 and my trigs around 20.since then on various drugs im now on atorvastatin and fenofrebate max doses my levels are about 4.8 my trigs are 3, they have saved my life- both my parents and siblings all have had heart bypasses .I know I get aches and pains in my joints and limbs but thats better than getting a heart attack i take extra vitamin D to combat the after effects.
