Lipids and sterols are critical components of our cell membranes, and are needed to ensure the transport of nutrients into and waste out of the cells. unfortunately, grain processing strips away the outer nutrient-dense layers that provide phytolipids, phytosterols and other vital nutrients from foods. this leads to inefficiency at the cellular level, leaving you feeling tired and sluggish as well. tre-en-en is the first and only whole grain lipid and sterol supplement proven to enhance energy and vitality by optimising cell membrane function. if cellular membranes are starved of vital nutrients, they become inflexible and can't perform critical functions. whole grain lipids and sterols allow your cell membranes to become their flexible best, making it easier for nutrients to get in and waste to get out.
