One packet a day, every day.
Start the day your box arrives and take one packet each night with water — ideally with food. Because it includes magnesium, which relaxes the body, evening is the sweet spot. Consistency matters: the nutrients build up over the first weeks.
Begin when your box arrives — no need to wait for the start of your period.
Take one packet in the evening with water, ideally with food. Magnesium can make you sleepy, so nightly works best.
Don't skip. One box is one full month — let the ingredients do their work.
By your second or third cycle, most people notice a more predictable pattern.

Frequently asked.
What does "cycle regularity" mean here?+
Cycle regularity is the length of time between periods and the consistency of that pattern. Bye Irregularity was formulated to support the underlying biology — the hormones, energy, and micronutrients — that drive a regular pattern.
How is this different from a prenatal?+
It's not a prenatal. It's a targeted formula for cycle regularity with inositol, magnesium, and chasteberry at doses chosen for that purpose. It also contains iron and folic acid, which are important if you're trying to conceive — but it is not a substitute for a prenatal.
How long until I notice a difference?+
Most people notice a more predictable pattern by the second or third cycle. The ingredients build up over the first weeks, so consistency matters more than the first month.
Can I take this with birth control?+
Yes. Bye Irregularity is hormone-free and does not interact with hormonal birth control. The ingredients are nutrients and a botanical — they work alongside other medications.
Is this safe while trying to get pregnant?+
Yes. The ingredients — inositol, magnesium, chasteberry, iron, and folic acid — are considered safe while trying to conceive. Many people take Bye Irregularity as part of a trying-to-conceive routine. Once pregnant, switch to a prenatal.
A more predictable cycle, one month at a time.
Start the day it arrives and take one packet each night with water — the evening timing suits its magnesium, which can make you sleepy. By your second or third cycle, most people notice a more predictable pattern.
