FAQ

Yes, all Frank Juice products are made entirely without animal ingredients and are vegan.

It's true that our bodies cleanse themselves, otherwise we wouldn't be able to survive. Our liver is our main organ for filtering and breaking down harmful substances, and makes sure that not too many toxins build up. Unfortunately, our time is marked by stress, bad air, environmental toxins, additives in food, little exercise and a mostly unhealthy diet. All of this affects the delicate balance of our bodies and can throw our inner balance off.

In our opinion, all adults can generally benefit from a cleanse. It should be built into your everyday life as a regular habit. It's also suitable for people who are lactose intolerant or who eat vegan, vegetarian or gluten-free. Teenagers under 18 should only do a cleanse with their parents' consent. A cleanse is NOT suitable for pregnant women, breastfeeding mothers or people with conditions that a cleanse could affect negatively. If you take medication, please be sure to check with your doctor whether a cleanse is right for you.

If you're pregnant or breastfeeding, you should NOT limit your diet to juices only. A cleanse doesn't meet the increased calorie and nutrient needs during this time. However, you can add our juices, soups or shots to your diet at any time as a supplement.

No. Fibre is an important part of a balanced diet. It is crucial for good digestion. But it doesn't contain nutrients. A cleanse is about no longer digesting food, an activity for which your body uses around a third of its energy every day. The digestive system is meant to rest in order to turn to other tasks. After your cleanse, we definitely recommend that you eat plenty of green vegetables and fresh fruit.

Proteins are built from amino acids. Your body breaks down the proteins it takes in into their components and then reassembles them into new "usable" proteins. It can also use plant protein very well, because all plants contain proteins, especially green ones! Don't believe us? Where do you think animals like elephants, buffalo and gorillas get their protein? From grass and leaves! You can also supplement your cleanse with our vegan protein powder in organic quality with just 3 ingredients (soy, pea, sunflower) and high-quality protein.

This is a question you should clarify with your doctor. There are two different types of diabetes and not both turn out to be problematic in combination with a Frank cleanse. Our answer is nevertheless: rather not, because of the high fructose content of some juices.

A clear YES! After all, there are no animal products whatsoever in our juices.

The Frank cleanse is gluten-free in principle. However, our white juice may contain traces of gluten (oats). You can easily have this juice swapped out by leaving a note when you order.

There's no universal answer to that. Of course, we think that cleansing and drinking cold-pressed juices should become a regular part of your life, and that you should keep to a certain regularity. Many of our customers therefore cleanse at the start of every month, others three to four times a year, and still others "only" at significant moments, such as New Year. The best thing is to simply try it out and let your own experiences and impressions convince you.

That depends on what you want to achieve with your cleanse. If you just want to give it a try because you don't know if it's for you, start with a 3-day cleanse. Occasionally the first three days come with cleansing reactions such as headaches or a slight feeling of dizziness. That's why we actually recommend a 5-day cleanse. Of course, five days take a bit more discipline, but we think: if you're doing it anyway, you might as well do it properly. The next step up would be 7 days. On request, you can also extend your cleanse to an even longer period.

One day of Frank cleanse consists of 6 x 330 ml of freshly pressed juice. Depending on the cleanse level (Starter, Medium or Pro), your juice cleanse contains 2x, 3x or 4x green juice. The more green juice in your cleanse, the less fructose and fewer calories you take in. We recommend that cleanse beginners start with the Starter cleanse to get used to the process.

Green juice contains all-rounders like spinach and celery, which have an extremely high nutrient and chlorophyll content.

Of course! A 1-day cleanse is the shortest form of short-term fasting. Some of our customers, for example, do a juice day every Friday. Or how about Wednesday: Monday, Tuesday, Cleanse Day!

Unlike a conventional centrifugal juicer, we use a special hydraulic cold-pressing process to make our juices. The fruit and vegetables are first turned into a pressable mash, and then several tonnes of pressure gently squeeze out all of the delicious juice, down to the last drop. With centrifugal juicers, the juice oxidises very quickly because of the high speed and is also heated. This has a strongly negative effect on the quality of the juice.

HPP is by far the gentlest, most natural and most vitamin-friendly way of keeping food, and juice in particular, fresh and shelf-stable for longer. And with pressure alone! Imagine you're at the deepest point of the ocean, take the pressure there times 6, et voilà, that's exactly how HPP works (6000 bar). No heat. No compromises.

Our juices are made and bottled south of Munich, near Lake Starnberg.

You'll find this information on the detail page of our juices. We know that calories matter a lot to many people. But in the end, it always comes down to the type of calories you take in. 100 kcal of green juice is not the same as 100 kcal of cheeseburger. We're pretty sure you won't put on weight from our juices, if that's what you're worried about.

Your juices keep for at least 14 days when refrigerated, from the time they're delivered to your home.

Frank Juice is made exclusively from fresh and natural ingredients. Just as no vegetable or fruit is 100% identical to another, our juices can also have slight differences in colour and consistency.

Frank Juice consists only of natural ingredients. No concentrates, no stabilisers, just fresh fruit and vegetables. The sediment and the separation of the juices is a quality feature and a guarantee of the freshness and naturalness of our products. Only artificial additives can prevent the natural sediment and separation of the juice. Just shake well before use, that's it.

As soon as you've ordered your cleanse, you'll receive a link to our Cleanse Guide with your order confirmation. It explains in detail how you should ideally behave before, during and after a cleanse.

Remember: it's a cleanse, not a diet! What matters here is how you behave before and, above all, after your cleanse. As a rule, you will lose weight during a cleanse. However, our cleanse isn't only about weight loss, it's above all a nudge towards a healthier you. In the long run, your goal should be to live more healthily and more mindfully, and to feel better overall as a result. That's how you reach your ideal figure in the long term, too.

Yes, you are! Of course, a cleanse takes a bit of discipline. But it wasn't designed to put you under pressure. You can combine a cleanse with one of our soups at any time. If that still isn't enough, there's a small cheat list in the preparation booklet. But it usually doesn't come to that.

Water with lemon or herbal tea is ideal. Do you know our Frank Teas yet? If possible, skip black tea, though. It often contains high amounts of theine. What you should absolutely stay away from are carbonated drinks, sugary drinks and lemonades of all kinds. You should also give up coffee and alcohol during the cleanse.

You want to skip green juice completely? Out of the question! Green juice is the linchpin of every cleanse and contains all the important vitamins, minerals, enzymes and antioxidants that make your juice cleanse a success. We now offer several different green juices. Give it another try!

You can. But don't overdo it. You're still taking in calories, just fewer of them. So limit yourself to light jogging or a long walk. Thanks to the conscious breathing, yoga and Pilates boost the cleanse effect and are therefore also a good option.

In general, you should schedule your cleanse for a period that gives you a certain amount of flexibility. Especially if you're doing a cleanse for the first time, you should take your time to feel your way into the whole thing. Generally, our juices fit into everyday life extremely well and you don't have to worry about where to get your lunch or dinner.

Mild withdrawal symptoms can occur, especially if your body is used to coffee or cigarettes. These may show up as headaches, slight nervousness and occasional dizziness. Skin blemishes can occur in isolated cases. All of this is a sign that your body is cleansing, and is therefore welcome. As soon as you order a cleanse, you'll receive our Cleanse Guide, which has plenty of tips on how to deal with these symptoms. If they happen at all.

In principle, you're flexible when it comes to the drinking order. What's important, though, is to start every day with the green juice. Nevertheless, we include a flyer with every package that recommends a drinking order. Make sure not to drink the last juice too close to bedtime.

Your body takes in food differently in the morning than in the evening. Since your body has had enough time overnight to empty the bowel, it is particularly receptive in the morning, meaning it uses all the vitamins and nutrients you give it especially well. That's why you start your cleanse with our rich green juice. If you're used to protein-rich food in the morning, you can also sacrifice part of your white juice.

Your juice should definitely be stored cool. A tip from us: since a Frank cleanse consists of at least 6 bottles, we recommend making some space in the fridge beforehand. This shouldn't be a problem, since you're giving up solid food during this time. Another option is to use our shipping box as a small fridge and swap the cooling packs regularly.

Your body is used to chewing solid food every day. The better you prepare for your cleanse with our Frank cleanse nutrition recommendations, the easier the changeover will be. We advise against chewing gum, as it can confuse your digestive system and contains either sugar or sweetener. Both are to be avoided during a Frank cleanse. If you really can't manage otherwise, eat a little apple. But make sure to chew it well.

Yes, you can, as long as we're talking about vegetarian, plant-based and natural ingredients, so primarily fruit and vegetables. The actual benefit of a cleanse is lost to some extent, but it's of course not unhealthy and therefore possible. The most important thing is that you feel good.

We chose our PET1 bottle for the following reasons:

1. Bear in mind that a 3-day cleanse consists of 18 bottles. Five days even contain 30 bottles. If they were made of glass, that would add up to a total weight of 9 kg of glass. 9 kg that has to be transported. That shipping has to be paid for. And afterwards the bottles also have to be disposed of.

2. We're working more and more with grocery retail. This requires a certain shelf life. Pasteurising is absolutely out of the question for us, as it destroys all the vitamins, enzymes and nutrients in the juice. So we chose HPP. On the one hand, that is very complex; on the other, it's impossible with glass bottles, as they couldn't withstand the enormously high pressure and would burst.

We've looked into that too. So far, though, without any notable prospects. For one thing, growing crops for bioplastic is highly controversial. For the fast growth of beets or corn, soil and groundwater are often heavily over-fertilised. For another, production causes a higher fine dust load than the conventional production of PET. Bioplastic is also difficult to recycle. For many waste disposal companies in Germany, the degradation time of approx. 3 months is far too long. For this reason, bioplastic often ends up in the incinerator together with conventional materials. Most recently, we've started using r-PET bottles. These bottles contain a certain proportion of recycled plastic. For our bottles, this proportion is at least 50%.
