An example embodiment may involve (i) receiving, by a server device, deoxyribonucleic acid (DNA) information associated with a user; (ii) parsing, by the server device, the DNA information to identify one or more single nucleotide polymorphisms (SNPs); (iii) determining, by the server device and based on the identified SNPs, an endocannabinoid genotype of the user; (iv) determining, based on the endocannabinoid genotype of the user, a recommendation of one or more cannabinoid formulations; (v) transmitting, to a client device associated with the user, a web-based representation of a first graphical user interface; and (vi) receiving, from the client device, an indication to display a detailed representation of a particular cannabinoid formulation of the one or more cannabinoid formulations.
