Build your stack
Pick your formulas. Keep one date.
Every formula runs the same 31-day cycle, so adding a second or a third changes nothing about your calendar. Select what you want below and the whole stack ships together, on one date, every month.
Questions
Asked, answered.
Does adding a second formula change my date?
No. Every 31 Vital formula holds exactly 31 doses, so a second or third bottle empties on the same day as the first. One reorder date, however many formulas you run.
Can I change the stack later?
Yes. Add or remove a formula any month from your account. The date stays where it is, because the bottle length never changes.
What if I start mid-month?
Start any day. The bottle runs 31 days from the day you open it, and that day becomes your reorder date.
