A fast and effective way to deliver Vitamins in to the system even if digestive efficiency is limited.By applying vitamin sprays directly into the mouth, ideally under the tongue, they are absorbed directly through the mucous membrane into the blood system rather than having to be processed by the digestive system and major organs. This ensures no loss during the absorption process. The solutions from better you have been microemulsified to ensure the particle size is optimal for absorption in this way. Dr Mercola sprays use Nano technology and a patented NanoMist delivery system that reduces the size of the B-12 molecule to microscopic Nano droplets, which delivers the nutrients to the body for fast and easy absorption. Because the digestive efficiency is not always assured, particularly when they are unwell or out of sorts sprays bypass the digestive system offering the fastest way of absorbing the vitamin.
