Juice cleanse during your period? How to find the right time in your cycle

Yes, a juice cleanse during your period is possible. However, many women find it more challenging during these days because they need more rest and warmth. For many, the cleanse feels easier in the days after their period. There are currently no robust studies that clearly recommend one phase. A recent review explicitly describes research on fasting and the female cycle as a gap (Review, 2026).

If you feel well during your period, there is little to stop you from doing your cleanse. If you experience severe discomfort during your period, choose a milder option or a later time. Our article explains whether a juice cleanse is suitable for you in general.

A cycle usually lasts around four weeks and proceeds in phases. After the period comes the follicular phase, during which the estrogen level rises. After ovulation, the luteal phase begins, during which mainly progesterone is produced (Frauenärzte im Netz). Every woman experiences these phases differently, including the days during the period, so it is best to listen to your own body.

Some recommend starting a juice cleanse in the first half of the cycle, that is, in the days after the period until ovulation. Many women experience this phase as a time of greater energy. This can help the cleanse feel easier than during the period.

Others prefer the second half of the cycle. Here, it is worth taking an honest look at appetite. A review found that women eat more on average during the luteal phase, usually around 200 to 350 kilocalories more per day than during the first half of the cycle (review, 2023). In the studies, the differences ranged from around 160 to more than 500 kilocalories. A cleanse during this time may therefore feel more challenging because the gap between your usual food intake and the cleanse is greater.

Yes, you can juice fast during your period, and many women do so deliberately. The important thing is to take it easy. During their period, many people notice that they need more warmth, rest, and sleep than usual. So do not schedule strenuous appointments or intense workouts for these days. A quiet weekend is often a better setting during your period than a full workweek.

During your period, pay particular attention to getting enough fluids, such as water and warm herbal tea between juices. Another point is iron. The body loses iron during menstruation, and the German Nutrition Society (DGE) gives 16 milligrams per day as the reference value for women before menopause (DGE, 2025). Juices provide only a small amount of it. A short cleanse during your period is usually not a problem, but after the cleanse, iron-rich foods such as legumes and whole grains should be a regular part of your meals again.

Typical companions during the first days of a cleanse, such as mild headaches or feeling cold, may feel more intense during your period. Our article on headaches, feeling cold, and hunger during a juice cleanse explains what can help.

Cycle-based nutrition means adapting your food and also a juice cleanse to the phases of your cycle. The idea behind it is that hormones, energy levels, and appetite change over the course of the month.

During the follicular phase directly after your period, many women feel more energetic. For many, this is a good time to start a juice cleanse. Energy levels usually remain high around ovulation. In the second half of the cycle and during your period, however, a gentler approach is more suitable, such as a shorter cleanse or more breaks.

This is how you plan with your rhythm rather than against it. Whether this works for you is individual. Always listen to your own body rather than following a rigid plan.

Preparation is even more important than usual during your period. One or two light preparation days beforehand can make the first day of the cleanse easier, as our article on juice cleanse preparation explains. Have a hot-water bottle, herbal tea, and comfortable clothing ready.

A shorter cleanse is often the better choice during your period. Three days are enough to interrupt your routine without overwhelming you. Our article Juice cleanse: 3, 5, or 7 days explains how to choose the duration. Gentle exercise such as walking or calm yoga is a good fit for these days.

During your period, also pay attention to the composition of the juices. A vegetable-focused cleanse contains less sugar than one focused on fruit, making these days calmer. DALUMA juice cleanses are vegetable-focused, cold-pressed, and organic; you can find all varieties in the juice cleanses overview. If you prefer to start cautiously during your period, choose the shortest option and extend it next time.

A juice cleanse during your period is possible, but for many people it is not the easiest time. Most find the days after their period the most pleasant time to start, while the second half of the cycle can be a little more demanding. There are no reliable studies supporting a fixed rule, so your own body awareness matters more than any plan.

If you fast during your period, keep the cleanse short and gentle, drink enough, and consciously plan time for rest. After the cleanse, add iron-rich foods back to your plate. Our article does a juice cleanse really do anything takes an honest look at what a cleanse can actually achieve.
