The present invention relates to cocrystals of Methylxanthines with Stilbenoids as coformers, their polymorphic forms and to the process for preparation thereof. The debittering of Methylxanthines is carried out by co-crystallization using Stilbenoids as coformers. The invention further relates to the preparation of polymorphic forms of debittered cocrystals and their use in nutraceutical and pharmaceutical compositions.
