Cycle System
YOUR NINE-DAY ROUTINE
Take Cycle System daily for nine days each cycle: the seven days before your period and the first two days of your period. Take 1 Day capsule in the morning and 1 Night capsule in the evening.
On harder days within that window, you may take 2 Day capsules in the morning and 2 Night capsules in the evening. Do not exceed 4 capsules in 24 hours. This is a nine-day routine, not an everyday supplement for the whole month.
28 CAPSULES, WITH ROOM TO ADJUST
Each box contains 28 capsules: 14 Day + 14 Night. Your nine-day routine uses 18 capsules at 1 Day + 1 Night daily. The 10 extra capsules let you take 2 Day + 2 Night on up to five of those nine days, if needed. You do not need to use the higher amount every day.
One routine for the days your cycle asks more of you.
Seven days before your period. Its first two days. Cycle System gives this nine-day window a simple morning-and-evening routine, with two different formulas and clearly marked capsules.
Day + Night, clearly separated
The Day formula brings together botanicals including fennel, ginger, turmeric, rhodiola, and chaste tree. The Night formula includes lemon balm, passionflower, and magnesium bisglycinate. Each capsule type has its own ingredient list and is individually sealed.

Every ingredient. Every milligram. On the label.
Day Capsule
| Ingredient | Dose | What it does |
|---|---|---|
| Fennel extract | 100mg | Traditionally used to support digestive comfort. Helps reduce bloating and supports the body in managing water retention. |
| Rhodiola extract | 100mg | An adaptogen that supports mood, mental clarity, and resilience during hormonal shifts. 4:1 concentrated extract, equivalent to 400 mg of rhodiola root. |
| Turmeric extract | 50mg | Supports a healthy inflammatory response and overall comfort. We use 95% curcuminoids for concentrated potency. |
| Chaste tree extract | 40mg | Traditionally used to support menstrual cycle comfort and hormonal balance. 4:1 concentrated extract, equivalent to 160 mg of chaste tree fruit. |
| Ginger extract | 10mg | Supports abdominal comfort and digestive ease. 10:1 concentrated extract, equivalent to 100 mg of ginger root. |
| Vitamin B6 (P5P) | 5mg | Most brands use a cheap, inactive B6 your body has to convert. We use P5P, the active form, for direct mood and clarity support. |
| Vitamin D3 | 2.5mcg | Vitamin D supports normal muscle function and immune health. Sourced from lichen (plant-based). |
| Black pepper extract | 5mg | Supports absorption of turmeric and other key ingredients. |
Night Capsule
| Ingredient | Dose | What it does |
|---|---|---|
| Yarrow extract | 80mg | A European botanical traditionally used to support abdominal comfort and ease cramp-related discomfort. 4:1 concentrated extract, equivalent to 320 mg yarrow herb. |
| Lemon balm extract | 80mg | Supports calm and relaxation. Standardized for consistent potency. 4:1 concentrated extract, equivalent to 320 mg lemon balm leaf. |
| Passionflower extract | 50mg | Supports restful sleep and helps ease the tension and restlessness that PMS can bring at night. 4:1 concentrated extract, equivalent to 200 mg passion flower aerial parts. |
| Magnesium (bisglycinate) | 30mg | Most supplements use magnesium oxide, which your body absorbs poorly. We use bisglycinate, chosen for bioavailability and gentle absorption. The form matters as much as the dose. |
| Vitamin B6 (P5P) | 5mg | Same active P5P form as the Day capsule. Supports neurological function around the clock. |
| Lavender essential oil | 2mg | Supports relaxation before sleep. |
| Sweet orange essential oil | 2mg | Supports a calmer evening wind-down. |
