How the 31 system works
Every bottle holds exactly 31 doses. Start any day of the month, take one dose daily, and the bottle ends exactly one month later. On subscription the next bottle lands on that same date, every month, and you can move, pause or cancel from your account.
What it supports
A routine you keep
One dose, once a day. The bottle covers the whole month, so nothing needs counting.
A stack that syncs
Every 31 Vital formula runs the same cycle. Add one, add three, everything restocks together.
A date you know
The renewal lands on the same day each month, because the bottle length is fixed.

The routine settles.
One dose, same time each day. The grid starts filling.

No decisions left to make. The first bottle completes on day 31.
The system is the habit.
The next bottle is already on the shelf. Reorders land on your date, every month.
Member voices
The month, kept.
First supplement routine I have kept past February. The bottle just ends when the month does.
Everything runs out on the same day. One order on the first, done.
I stopped counting pills. Turns out that was the whole problem.
Questions
Asked, answered.
Why 31 and not 30?
31 matches the longest month. In a 30-day month you end with a dose of margin, in February with two or three. You never open an empty bottle.
When does my order ship?
On your date, every month. You can move, pause or skip any month.
How is this tested?
Every lot is manufactured under cGMP (21 CFR Part 111) with a certificate of analysis on file, and third-party tested before release.
