The Science
The Thinking Behind
PeriPak
Your month has a rhythm. PeriPak gives each week its own formula, so your support isn’t the same on Day 1 as on Day 28.
Why a Weekly System
One formula every day
isn’t built for a changing month.
Many women notice that sleep, mood and energy shift across the month in these years. PeriPak gives each week its own formula, each built around a different kind of support.
Week 1 · Replenish+
Formulated to support recovery and nutrient replenishment at the start of the month.
Week 2 · Ignite+
Formulated to support steady energy, stamina and motivation. Supports focus and mental clarity.
Week 3 · Center+
Formulated to support a calm, balanced mood and emotional resilience. Helps the body manage everyday stress.
Week 4 · Exhale+
Formulated to support restful sleep and relaxation, and the body’s natural wind-down at the end of the month.
Four weekly formulas. One capsule a day. One simple system.
Understanding Perimenopause
Perimenopause is the transition before menopause, and it can last 4–10 years. It often begins in a woman’s 40s, and for some women it starts earlier.
During these years, hormone levels shift in less predictable ways. Many women notice changes in sleep, mood, energy and the length of their cycles.
You’re not imagining it. This is a real stage of life, and it deserves support designed for it.
