Solgar is proud to introduce Solgar Platinum Edition - the first line of nutritional supplements to use nanotechnology to deliver unprecedented bioavailability. Fat-soluble nutrients are essential to health but are not very bioavailable. That is because in order to be absorbed, they must first be converted in the body to a water-soluble form. Unfortunately, this "pre-processing" is imperfect, causing a significant - and sometimes near-total - loss of active ingredient.A Solgar first, Nutri-Nano is a patent-protected nanotechnology that transforms fat-soluble nutrients into water-soluble ones - significantly increasing absorption. How? Through surrounding the fat-soluble molecules with a water-soluble shell called a micelle, which is only 30 nanometers in diameter. (A nanometer is one-billionth of a meter). The micelles carry the fat-soluble nutrient directly to the absorption site, where it is released and absorbed.
