Defend is the maintenance phase — and the phase most customers stay in once they reach it. A monthly rhythm of probiotic refills, the Nourish stack continuing, and the Incubator for at-home yogurt culture.
Defend isn't an end-point. It's the running protocol of someone whose gut works. The reason the brand has a six-product monthly subscription bundle is that most reset customers convert to it within ninety days.
Customers in Defend report a particular shift: gut work stops being a project. The box arrives, the rhythm continues, and the ecosystem holds. That's what the phase is for.
