Clathrate, a host-guest complex, is a compound where molecules (guests) are trapped within the lattice of other components (hosts) creating a ‘tube-like structure’ In HydraDuct-B3 the lattice is made of glycerin and urea (hosts) and the other components are B3 precursors (guests). The originality of HydraDuct-B3 is to create an entrapping structure to sequester B3 precursors from pumpkin seeds, squash seeds and bacillus ferment. This is an original association of simple ingredients with a very unique delivery mechanism.
