in regards to cholesterol your obviously going to have to look at fitness and obesity (the more obese the higher the fat storage in the apoproteins, therefore the more free LDL/cholesterol there will be lying about in the blood which is not going to be able to be uptaken by the liver
metabolism would be more to do with glucose...obviously diabetics would have a lack of metabolism as there is a lack of insulin release/utility so lack of uptake of glucose into skeletal muscle
from what i know the person who posted these results, its his mother in law whos results they are and they are currently taking a few other medicines, however those medicines are long term and these results are from the addition of vascepa, so most of the effects seen should be due to vascepa, if not a synergistic effect of vascepa working with the other medicines (which would be great for combo news tbh)
