Every Phase Matters

Phase One - Cycle Support

Phase One - Cycle Support

Formulated by Cynthia Donovan, MS, RDN, CDN — Period Nutritionist

Your cycle is one of the most powerful indicators of your overall health — and for active women, it's often the first thing to suffer.

Whether you're training hard, managing stress, under-fueling, or simply trying to stay ahead of hormonal imbalances, Phase One - Cycle Support was built for you. This isn't just a supplement for women in crisis — it's daily nutritional support for every active woman who wants to protect, optimize, and understand her cycle.

Who It's For

  • Active women who want to support their cycle while training
  • Women experiencing irregular cycles or hormonal imbalances
  • Women recovering from Hypothalamic Amenorrhea (HA) or period loss
  • Women under high stress with demanding schedules
  • Women focused on long-term bone and hormone health
  • Women recovering from under-fueling or RED-S
  • Women who want to stay ahead of hormonal drift before it becomes a problem

What's Inside

  • Magnesium Glycinate (300 mg) — calms the nervous system, improves sleep quality, and reduces stress reactivity to support healthy reproductive signaling
  • Vitamin D3 (2,000 IU) — supports endocrine function, mood stability, and addresses deficiency common in active women
  • Vitamin K2 as MK-7 (100 mcg) — works with D3 to support calcium utilization and long-term skeletal integrity
  • Zinc Bisglycinate (15 mg) — supports stress tolerance, neurotransmitter function, and hormonal recovery
  • Calcium Citrate (300–500 mg) — protects bone density during low-estrogen states and supports overall skeletal health

Why Phase One

Most women's supplements are built for the average person. Phase One is built for the woman who pushes herself — and needs her body to keep up. Every ingredient was chosen specifically to support the hormonal pathways most vulnerable to training stress, under-fueling, and a demanding lifestyle — including those affected by Hypothalamic Amenorrhea (HA).

Clean ingredients. No fillers. Formulated with active women in mind.
