Coffee during the juice cleanse?

Better not to, but don’t stop abruptly either. Traditionally, caffeine is stopped no later than the day before fasting begins (DGE, 2018). If you drink several cups a day and only stop on the first day of your cleanse, you’ll be dealing with caffeine withdrawal on top of fasting. That’s why it’s worth reducing your coffee intake in the days beforehand, so coffee doesn’t become an issue during your juice cleanse.

The table also shows why coffee makes such a difference during a juice cleanse. One large cup contains more caffeine than several cups of green tea.

Having a single cup of black coffee in the morning during a juice cleanse is no big deal if you’re otherwise struggling with withdrawal. Skip the milk and sugar, as they add extra calories to your cleanse.

Caffeine is a regular part of the day for many people. When it suddenly disappears, the body often reacts with headaches, fatigue, and a bad mood. A randomized study of 100 regular coffee drinkers examined this in 2026. On days without caffeine, participants had headaches on 30 percent of days, compared with just 10 percent of days when they drank coffee (Randa and colleagues, 2026). When headaches did occur, they were also significantly worse without coffee. This is exactly what many people experience when they give up coffee overnight during a juice cleanse.

For your cleanse, this means that if you suddenly give up coffee during a juice cleanse, it’s easy to mistake withdrawal for the fast itself. Both feel similar, and in the end, the cleanse gets the blame.

The best way to handle coffee during a juice cleanse starts three to four days beforehand. Instead of quitting overnight, gradually cut down by half. This gives your body time to adjust before you also stop eating.

• Four days beforehand, cut your usual number of cups in half.
• Three days beforehand, replace one cup with green tea.
• Two days beforehand, have one small cup in the morning; stick to tea and water for the rest of the day.
• On the day before the cleanse, skip coffee, as is also recommended for traditional therapeutic fasting.

With this step-by-step plan, coffee during a juice cleanse is no longer an issue for most people. If you usually drink five cups or more, it’s best to allow five days so giving up coffee doesn’t spill over into the first days of your cleanse.

Not everyone can give it up, and that’s okay. If you have a severe headache on the first morning despite preparing, a small cup of black coffee is often a better choice than giving up on the day. The important thing is to stick to that one cup. A simple rule for coffee during a juice cleanse: no more than one cup, only in the morning, and always black.

Decaffeinated coffee can help you keep the ritual. The taste stays the same, and so does the cup in your hand; it’s just largely free of caffeine. For some people, that’s exactly the trick to replacing coffee during a juice cleanse without feeling guilty.

It’s a different story if you’re sensitive to caffeine, pregnant, or taking medication. In that case, it’s best to ask your doctor about coffee during your juice cleanse beforehand. During pregnancy, EFSA recommends no more than 200 milligrams of caffeine a day anyway, or about two cups of filter coffee (Federal Center for Nutrition, 2026).

A new morning routine helps most. The warm mug is often more important than the caffeine. Many people miss coffee during their juice cleanse more as a ritual than as a pick-me-up. Herbal tea in the morning, such as ginger or peppermint tea, gives you the same ritual without withdrawal.

Green tea is a gentle transition. It contains caffeine, but much less than coffee. During the first few days of your cleanse, a cup in the morning can make it easier to give up coffee during your juice cleanse. After that, water and herbal tea throughout the day are enough. Many people find that on the second or third day, they miss coffee during their juice cleanse less than they expected.

Pay attention to the sugar in your juices, too, as it affects how alert you feel throughout the day. Vegetable-based juices make for a steadier day than fruit-heavy ones, as our article on calories and sugar in a juice cleanse explains. Find all the options in our overview of juice cleanses.

Coffee during a juice cleanse isn’t forbidden, but it can be an unnecessary stumbling block. Giving it up gives many people headaches, which was clearly measurable in a 2026 study. That’s why it’s best to cut back on caffeine in the days before your cleanse. If you plan ahead for coffee during your juice cleanse, you’ll start more calmly and won’t let withdrawal take over the first few days.

If you still feel the urge on the first morning, a small cup of black coffee is better than quitting. In that case, coffee during the juice cleanse remains the exception, not the rule. The same applies in reverse afterward: start with one cup and see how it sits with you. Our article explains how: how to reintroduce foods properly after a juice cleanse.
