If you are using time released supplements, you should take them with food to ensure that they move through your body at the right pace and release the proper amount of nutrients and vitamins your body needs at the right time.

Cholesterol, which is a fatty substance found in many foods, is absorbed by the body then transferred from the liver to be stored by tissue as fat. This is carried through the bloodstream by molecules known as LDL (Low Density Lipoproteins). When the LDL is oxidized, it reacts to the cholesterol and a fat substance known as plaque begins to get deposited on the artery walls, which causes the blood flow to stop.
