The service personalizes product selection to customers' dietary needs and preferences (e. g. , organic, gluten-free, high-protein, low-sugar), emphasizes strict product standards (non-GMO, no artificial flavors/colors, no synthetic preservatives, etc. ), and provides scheduled delivery and repeat-order capabilities. Thrive Market also runs a social-impact component—sponsoring one-year memberships for people in need, accepting SNAP EBT, and donating healthy groceries and disaster relief funds.
