Your symptoms point to
Excess Estrogen
Here is what it means, why it shows up, and what your body is asking for.
What this often feels like
Women with this pattern describe some combination of the following:
Bloating that arrives in the second half of your cycle and lingers for days
Mood shifts and irritability that feel like a different person taking over
Periods that are heavy, painful, or both
Headaches or migraines that follow your cycle on a predictable pattern
Cyclical breakouts or acne that flare in the same window each month
Weight that holds on around the hips and thighs no matter what you change
Breast tenderness or fullness in the days leading up to your period

What This Pattern Is
Excess estrogen is not as simple as producing too much
Excess estrogen is one of the most common cyclical patterns women experience, and one of the most misread. It is rarely about your body producing more estrogen than it should. More often, it is about estrogen not being broken down and cleared as efficiently as it could be.
The liver, the gut, and the nutrient pathways that move estrogen through and out of the body all play a role. When any of those systems are under-supported, estrogen builds up in circulation and the symptoms follow. The cyclical nature of what you feel is your body telling you exactly where in the cycle the support is needed.
Cycle Sync supports your body's natural estrogen rhythm and clearance.
Why This Happens
Several things shape this pattern
Modern life adds to the picture in ways previous generations did not face. Endocrine-disrupting chemicals like BPA in plastics, phthalates in fragrances, and parabens in personal care products all contribute to the body's estrogen load. Diet and gut health matter too. A liver carrying a heavy detoxification burden, or a gut that is moving slowly, both slow the clearance of estrogen.
Stress and sleep disruption add another layer. When cortisol stays elevated, the body diverts the precursors that would otherwise become progesterone, leaving the estrogen-progesterone ratio further out of balance. The result is a pattern that tilts estrogen-heavy and shows up in the second half of your cycle.
How Cycle Sync supports this pattern
Two phases. Two formulations. One body finally being supported the way it works.
Phase 1:Builds the foundation
In the first half of your cycle, estrogen rises naturally as your body prepares for ovulation. Phase 1 supports the liver and inflammatory pathways from day one, building capacity before the heavy clearing work begins. The result is a body better prepared to handle the second half of the cycle.

Phase 2:Brings in the clearing nutrients
In the second half of your cycle, estrogen needs to be broken down and cleared. This is the half of the month where the excess estrogen pattern is most felt, and Phase 2 is built specifically for it. DIM and Calcium D-Glucarate sit at the center of the formulation as the two ingredients that exclusively appear in this phase, doing the dedicated estrogen-clearing work. Magnesium and Chasteberry work alongside them to support the calmer luteal-phase rhythm women with this pattern have been reaching for.

What women on the routine are saying
★★★★★
"I was actually able to sleep through the night during my last cycle. Menstrual cramps used to wake me every 3 to 4 hours once my pain meds wore off. Now I only need pain medicine a few times a day instead of around the clock, and I had no cystic acne breakouts."
★★★★★
"Less hormonal acne, a less painful period, and overall just felt better. I love the way this helps naturally support your body."
★★★★★
"I noticed changes in the first month. I used to get cystic acne on my cheeks and jawline around ovulation and leading up to menstruation. That has significantly decreased."
★★★★★
"Less bloating, more consistent energy. Still some mood swings around my period but nowhere near as bad. My period also started on day 29 instead of the day 34 to 36 it usually does."
★★★★★
"The emotional shifts during certain parts of my cycle used to feel really intense and hard to manage. Since taking Cycle Sync, those have significantly decreased and my cycle feels much more balanced. I feel more emotionally stable throughout the month."

How to use Cycle Sync
Built around your cycle, not your calendar
Phase 1 · Days 1–14
Start on day one of your period
Phase 1 runs from the first day of menstruation through ovulation. This is the half of your cycle when estrogen is rising and your body is preparing for the luteal work ahead.
Phase 2 · Days 15–28
Switch at ovulation
Phase 2 runs from ovulation through the day before your next period. This is the half where DIM, Calcium D-Glucarate, Magnesium, and Chasteberry do the heavy lifting for the excess estrogen pattern, supporting your body's natural clearance work.

A few common questions
When should I expect to notice a difference?
Most women notice early signals in their first cycle, with the most meaningful shifts arriving between cycles two and three. Cycle Sync supports your body's natural rhythm, which is why one cycle is your starting point. The closer you can track your cycle alongside it, the better the results.
When do I switch from Phase 1 to Phase 2?
On the day of ovulation. If you do not track ovulation yet, take Phase 1 for the first 15 days of your cycle and Phase 2 for the remaining days. Your first order includes a cycle-tracking guide to help you align the switch more precisely over time.
What if my cycle is shorter or longer than 28 days?
Cycle Sync is built for cycles of any length, as long as you have one. Knowing your ovulation day lets you align the phase switch. If your cycle is longer than 30 days, there may be a few days between bottles. If your cycle is shorter, you may switch a few days earlier. The two-phase structure adapts to your body, not the other way around.
Why two bottles instead of one?
Because your body works in two phases. Phase 1 brings in foundational nutrients that support the liver and inflammatory pathways through the rising-estrogen first half of your cycle. Phase 2 brings in DIM and Calcium D-Glucarate, the two ingredients that exclusively appear in this phase to do the dedicated estrogen-clearing work. One pill cannot do both jobs well.
Can I take this with hormonal birth control?
Hormonal birth control delivers synthetic hormones that suppress ovulation. Cycle Sync is built to support a natural cycle, so it is not recommended for women currently on hormonal contraceptives. If you came off birth control recently and your cycle is returning, Cycle Sync is built for that window. Reach out at hello@rootifysupplements.com if you want guidance.
Is it safe during pregnancy or breastfeeding?
Cycle Sync is not recommended during pregnancy or breastfeeding. A prenatal is what your body needs during those windows. Cycle Sync is safe to take up until conception.
How does the subscription work?
Your 30-day routine ships every 30 days so you always have what you need for the next cycle. You can pause, skip, change the cadence, or cancel from your account at any time. No phone calls, no hoops.
How is Cycle Sync different from other PMS supplements?
Most PMS supplements are a single formula taken every day, with no respect for the fact that the body is doing different work in the first and second halves of the cycle. Cycle Sync is the only two-phase system we know of, formulated by an OB-GYN and Registered Dietitian, with every ingredient and dose disclosed.
What if it does not work for me?
