28 Days. 4 Phases. 1 Cycle of You.
Your cycle does not need to be exactly 28 days. Phase timing varies, and the app adapts to the cycle information you record.
You were never inconsistent.
You were cyclical.
Your period is only one part of your menstrual cycle. 28FOUR is being built to support the changing nutritional context of all four phases—and to make the daily routine feel simple.
Why it’s simpler
A simpler way to support your whole cycle.
No supplement spreadsheet. No identical routine every day. No boxes arriving before you need them. 28FOUR follows your cycle, guides your daily formula and helps you know when each phase is running low.
The system
Four formulas.
One connected app.
Your 28FOUR Starter System brings four reusable glass bottles and your first supply of each phase formula. After that, you refill only the phase that runs low — never the whole system, and never on a fixed monthly schedule.
The app follows your cycle and tells you which formula to take, how many capsules, when your phase is changing and when you’re running low.
Cycles vary. Phase timing is estimated and becomes more personal as you record your cycle.
Why 28FOUR exists
Women were never the problem. The framework was incomplete.
We have spent generations being told to expect the same energy, focus and capacity from ourselves every day. When that changes, we call ourselves inconsistent.
But the female body is not designed to remain static.
28FOUR exists so women can understand the complete rhythm of their bodies — and have products, education and daily support built around that reality.
The future of women’s wellness is cyclical.
