28four

28 Days. 4 Phases. 1 Cycle of You.

28 Days.
4 Phases.
1 Cycle of You.

A new era of cycle-specific menstrual wellness.

You were never inconsistent.

You were cyclical.

For generations, we have been taught that our menstrual cycle is simply the days we bleed. That was never the full story.

Our bodies move through four distinct phases—each with its own shifting rhythm, needs and strengths. 28four was created to help women understand and support the whole cycle.

Restore

A time to turn inward. To restore, replenish and listen more closely to what the body is asking for.

Follicular phase campaign image

02Days 8–14

Follicular

Renew

Energy begins to rise. Curiosity returns. The body moves into a phase of renewal, possibility and forward motion.

Ovulatory

Radiate

Expression, connection and outward energy come into focus. A phase of visibility, communication and radiance.

Luteal phase campaign image

04Days 22–28

Luteal

Rebalance

The pace begins to shift. Awareness turns inward again, creating space to rebalance, refine and prepare.

Four phases. One rhythm.

Understand your cycle

The system

One cycle was never meant to be supported in one way.

Four phase-specific formulas, connected through one intelligent cycle-tracking app.

28four is a four-part cycle support system created around the Menstrual, Follicular, Ovulatory and Luteal phases.

Each phase has its own formula, identity and daily guidance. The 28four app tracks where you are in your cycle and tells you which formula to take, and when—so the supplements and the app work as one connected system.

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. Unmotivated. Too emotional. Not disciplined enough.

But the female body is not designed to remain static.

28four was created from the belief that women deserve to understand the complete rhythm of their bodies—and to have products, education and daily support built around that reality.

We are not here to make women easier to manage.

We are here to give women the language, knowledge and tools to understand themselves differently.

This is cycle support for the whole month—not only the days you bleed.

The future of women’s wellness is cyclical.
