You have tried generic vitamins. You have done the routines. Here is what they were missing.

Your energy, your mood, your recovery: none of them stay the same all month. They shift with every phase of your cycle.

When you take the same supplement every single day, you are giving your body nutrients it does not need right now, and missing the ones it actually does. That is not a willpower problem. That is a structure problem.

Cycle Sync was designed to fix exactly that.

Two phases. Two formulations. One body finally being supported the way it works.

We designed Cycle Sync to reflect the natural flow of estrogen and progesterone across the menstrual cycle. You will see below the shift from rising estrogen in Phase 1, to rising progesterone and breaking down estrogen in Phase 2. Mimicking this flow with the right ingredients will help you feel your best and support a healthy, consistent cycle.*

Phase 1 · Days 1–14

Menstruation + Follicular

Estrogen is rising

Your body is repairing and building.

The first half of your cycle begins with menstruation, then moves into the follicular phase as your body prepares for ovulation. Estrogen rises steadily throughout this window. Phase 1 is formulated to support iron stores, energy metabolism, and antioxidant pathways to match this biological phase.*

Rising Estrogen Energy + Iron Support*
Phase 2 · Days 15–28

Ovulation + Luteal

Progesterone rises

Estrogen begins to break down.

After ovulation, progesterone takes the lead while estrogen begins to metabolize. This is when many women feel the most shift in mood, energy, and comfort. Phase 2 is formulated to support nervous system function, progesterone production, and estrogen metabolism during the second half of your month.*

Rising Progesterone Calm + Balance Support*

Two bottles. Taken at the right time in your cycle. That is the system.

Clinically proven and trusted by practitioners around the country

“I use Cycle Sync in my practice because it supports women through every phase of their cycle. The formulations are high quality, research-backed, and reflect how I care for my patients. It’s also priced in a way that makes it accessible, which means my patients can actually stay consistent.”

What happens in your first 90 days.

Weeks 1–3

The first signals.

Your body is adjusting to phase-based nutritional support. Many women begin to notice shifts in how they feel during different parts of their cycle. Sleep and stress patterns start to shift. These early signals tell you the structure is working.*

Weeks 4–7

The shift you have been waiting for.

This is where most women feel the difference. The cyclical pattern becomes clearer, mood becomes more stable week to week, and energy feels more consistent across the month.*

Weeks 8–12

The routine clicks.

By weeks 8 to 12, the structure becomes second nature. Your cycle tracking feels more predictable. Your routine is locked in. Your overall sense of wellbeing reflects the consistency you have built.*

The Formula

12 clinically backed ingredients. Every one chosen for a reason.

Cycle Sync is not a general women's multivitamin. Every ingredient was selected for what your body needs at a specific point in your cycle, backed by published research, and formulated by practitioners who work with women's hormones every day.

Vitamin B6

P-5-P (active form)

50–100 mg

Magnesium

Frequently Asked Questions

  • Because hormones fluctuate between the follicular and luteal phase, we want to prime the right nutrients into the body to align with this fluctuation to set up for optimal balance.

  • Birth control and other hormonal contraceptives work by delivering synthetic hormones (like estrogen and progestin) to suppress ovulation and create changes in the cervix and uterine lining. Cycle Sync could interfere with or alter the intended effects of birth control, including decreasing its effectiveness in preventing pregnancy.

    Therefore, the question to ask yourself is, why am I taking birth control? If it is for preventing pregnancy, Cycle Sync may not be your answer. But if the reason is something else, such as acne, painful periods, or hormone imbalance, it may be worth looking into trying to balance your hormones naturally instead with Cycle Sync. It does take time and effort, and should be under the supervision of a healthcare professional.

  • If you are having a period, start Phase 1 on the first day of menstruation. Take Phase 1 for 15 days and phase 2 until next menstruation. It would be advised to track your cycle while taking this product for best results. Knowing your ovulation day will allow the proper time to transition between phases.

    If you have not had a period for more than 3 months, it would be advised to contact your healthcare professional before starting Cycle Sync.

  • It is not suggested to take while pregnant. A prenatal should be taken during pregnancy and lactation. Cycle Sync is safe to take up until conception.

  • Yes, this can help alleviate estrogen dominance symptoms and help hormone production during perimenopause years.*

  • You should see improved symptoms within a couple weeks. However, it is suggested to take for at least 3 months before seeing changes in your menstrual cycle. The closer you can track your cycle to this product, the better the results. The product should also be accompanied by healthy habits such as proper hydration, daily movement, quality sleep, reducing stress, and an anti-inflammatory nutrition approach.*

  • It is suggested to take Cycle Sync with your first meal of the day. Taking without food may cause indigestion.

  • The use of this product should be consulted with a physician before using for those under the age of 18.

  • Hormone Tracking with Apps - The Natural Cycles app is compatible with Oura Ring, Apple Watch, and NC° Thermometers. The algorithm automatically syncs & analyzes your data for you. It can even monitor physical and emotional changes to spot patterns and get alerts for irregularities.

    Hormone Tracking with Wearables - Devices like Tempdrop, Ava, or Oura track BBT, HRV, and sleep to estimate ovulation.

    Basal Body Temperature (BBT) Method - Use a basal thermometer to measure body temperature every morning before getting out of bed. Before ovulation temperature is lower (97.0°F–97.7°F) and after ovulation progesterone causes a temperature rise (above 97.8°F). When there’s a half-degree rise in your temperature, you’re ovulating.

    Calendar method - Track cycle length (from the first day of one period to the first day of the next). Subtract 14 days from your cycle length to give you an estimated ovulation day. For example, for an average 30 day cycle, your estimated ovulation date is Day 16. The more data you have on cycle length (multiple months worth), the more accurate the estimation. This method is likely to be the least accurate of those listed above.

  • Phase 1 includes menstruation and the follicular phase, while Phase 2 includes ovulation and the luteal phase. Therefore, on the day of ovulation, you will switch into Phase 2. Use the above tracking methods to correctly track your cycle. If unable to do so, take Phase 1 for 15 days, Phase 2 for 15 days.

  • This is where tracking your ovulation is very important, so you can still align the phases correctly. Some may experience a shorter or longer follicular phase, some may experience a shorter or longer luteal phase. By knowing your ovulation day, you know when to switch to the next phase. If your cycle is longer than 30 days, there may be a couple day gap between taking the next phase.

  • A proper cycle will help with fertility, so yes it can help regulate hormones for conception. In particular, this product helps solve progesterone insufficiency, which is a common cause of fertility issues. In addition, tracking your cycle will help you determine your ovulation day, which is very important for knowing what days you are most fertile.*

  • Yes, but it may not be as efficient. It will help lower inflammation and provide proper detoxification, but it will not necessarily help improve hormone levels to the same degree due to lower hormone production at this stage.*

  • We believe that this product is more effective when taken consistently in alignment with your menstrual cycle. By having a subscription, the product will constantly be at your door step to transition into that next month and keep you on track. This also allows you to customize the length of phases, as the bottle has 15 servings for each phase, but you can use next month’s supply to customize this for longer/shorter cycles.

  • It does not contain any synthetic hormones. All the ingredients are aimed to help aid in the natural production of hormones.
