my cholesterol has been under 150 for the last 4 yr, and I have a lot of brain fog, depression, trouble concentrating, lightheadedness, confusion, etc, even when sugar levels are 90 -120. I eat meat, eggs, fish am only 32. Any connection? no meds. Do vitamins or mineral supplements raise or lower cholesterol? when my total cholesterol was under 100 it was horrible! Its better now with a level of 144, the highest its been for four yr. How do you get it up if that number is a problem? blood pressure is 100-120 over 60-80.
