Each serving of LifePak Nano is delivered in a convenient twin sachet packet; one side contains five dry capsules, and the other side con-tains two CR-6 LipoNutrients softgel capsules. The meaning of the name CR-6 stands for the six carotenoids (CR=carotenoid) present in the softgel capsule. In addition to the six carotenoids, other fat-soluble vitamins are delivered along with essential omega-3s (equivalent in potency to a serving of MarineOmega). The name CR-6 LipoNutrients refers to all the contents of the softgel, all of which are fat-soluble nutrients and are enhanced through pre fat-dissolved delivery, or enhanced with nanotechnology.
