Quick answer

During fasting season, general nutritional support moves into focus: magnesium contributes to electrolyte balance, to normal muscle function, and to the reduction of tiredness and fatigue – a sensible building block on days with reduced food intake, complemented by a base package and a sleep complex for the night.

Fasting has a long tradition and, at the same time, is enjoying huge popularity as a modern health routine. The spectrum ranges from religiously rooted fasting periods to popular intermittent fasting – as varied as the motives are, the underlying question is just as similar: how do I sensibly nourish my body during a phase with less food?

Whether it's intermittent fasting, a multi-day fasting cure, or the classic Lenten fasting period before Easter: anyone who deliberately abstains from food or strongly reduces it changes their energy and nutrient intake for a while. Many people experience fasting as a beneficial break for body and mind. At the same time, the question arises of how to keep an eye on your basic mineral supply during such days – the electrolyte balance in particular takes on special importance during fasting.

For the purpose of a fasting companion, we've put together a set focused on electrolytes, broad general nutritional support, and evening calm. It's meant to sensibly accompany mindful fasting days without undermining the idea of fasting itself.

Fasting today takes many forms: some set a daily eating window in everyday life, others plan a multi-day fasting week once a year, and others still deliberately give up certain things during the classic Lenten fasting period. As different as these forms are, they share one thing – the body temporarily gets less, or no, solid food, and therefore also less of the minerals that normally come in through meals. Drinking a lot also increases excretion. That's exactly why the mineral and electrolyte balance moves more into focus during fasting than it otherwise would.

Why This Combination for Fasting Season

During fasting, the electrolyte balance takes centre stage, because fewer minerals are supplied through food. That's why magnesium is the central building block: it contributes to electrolyte balance, contributes to normal muscle function, contributes to normal functioning of the nervous system, and contributes to the reduction of tiredness and fatigue. These functions are especially relevant on days with reduced food intake.

Around the magnesium foundation, a base package for metabolism and energy, an amino building block, and a sleep complex for the night complement each other. This way, the set accompanies this mindful time from morning to evening – with a focus on general nutritional support rather than extra calories.

One note upfront that stands above everything else: fasting isn't suitable for everyone, and longer fasting cures ideally belong under professional supervision. The following set is intended as a supplement for healthy adults who fast deliberately – not as a licence to ignore health limits. Especially with multi-day or therapeutic fasting, the question of which nutrients make sense when should be clarified with medical supervision.

The Products in the Set

The following building blocks range from the magnesium foundation in two forms, through an amino building block and a broad base package, to a sleep complex. Depending on your form of fasting, pay particular attention to the ingredient lists – the descriptions below explain what fits which situation.

Magnesium Complex – Four Sources, 400 mg Elemental

The Magnesium Complex with four bioactive sources and 400 mg of elemental magnesium is the centrepiece. During fasting, magnesium supports electrolyte balance and normal muscle function, and contributes to the reduction of tiredness – the obvious building block for mindful days.

Magnesium Bisglycinate – Chelated and Gentle on the Stomach

Magnesium Bisglycinate is a chelated form of magnesium that's gentle on the stomach. Especially when the stomach is empty during fasting, many people appreciate a particularly well-tolerated variant. It can be used flexibly throughout the day or in the evening.

Scheunengut Essentials – Magnesium & Amino Intenso

Scheunengut Essentials combines the Magnesium Complex and Amino Intenso. Amino acids are the building blocks of the body's own proteins – a popular building block for people who keep an eye on their protein building blocks even while fasting. As a duo pack, they're the practical combination.

Metabolism & Energy Complete Package

The Metabolism & Energy Complete Package brings liver, thyroid, and magnesium into balance. As a base package, it extends general nutritional support during fasting season beyond magnesium alone.

Steinbrecher – Chanca Piedra with a Vitamin Building Block

The Steinbrecher combines chanca piedra with banana, lemon, and a vitamin building block in lab-tested quality. Since drinking enough fluids is central to fasting anyway, this building block fits well into a fasting routine.

Melatonin Sleep Complex – For the Night

The Melatonin Sleep Complex with 1 mg of melatonin per tablet and magnesium rounds off a fasting day. Melatonin contributes to the reduction of time taken to fall asleep (when 1 mg is taken shortly before going to bed) – helpful while the body gets used to the changed routine.

This makes the set a small toolkit for mindful days: the magnesium foundation in two forms for the electrolyte balance, the amino building block and the broader base package for general nutritional support, and the sleep complex for the night. Not everyone needs all the building blocks – for many people who fast, magnesium is the central point, and everything else is optional. What matters is that you choose deliberately depending on your form and duration of fasting, and keep an eye on the ingredient lists.

How to Combine Them

Think in terms of segments of the day. During the day: the Magnesium Complex or the Essentials support your electrolyte balance; drink plenty of water and unsweetened beverages. As a base: the Metabolism & Energy Complete Package and the Steinbrecher can be built into a daily routine. In the evening: the stomach-friendly Magnesium Bisglycinate fits well into an evening routine, and the Melatonin Sleep Complex shortly before bed supports falling asleep.

Please note: some supplements contain small amounts of calories or additives. If you're fasting strictly, check the label information and decide what fits your form of fasting. With water fasting or therapeutic fasting, intake belongs under medical supervision.

One recurring misunderstanding is worth clearing up: pure minerals like magnesium, without any notable calories, don't trigger a relevant insulin response, which is why many people also use them during stricter fasting phases. However, as soon as a product contains amino acids, sugar, flavourings, or other calorie-containing ingredients, it's no longer “true” fasting depending on the definition you use. How strictly you handle this is your decision – what matters is that you know the ingredient list and choose deliberately instead of relying on assumptions. With intermittent fasting, you elegantly sidestep the question by taking supplements within your eating window.

Fundamentals First

Fasting is, first and foremost, a matter of the right framework: drinking enough, listening to your body, choosing the form of fasting that fits your own situation, and not setting an overly ambitious duration. People with pre-existing conditions, pregnant women, breastfeeding women, and adolescents should seek medical advice before a fasting cure. A balanced diet during eating phases supplies most nutrients. Supplements come in where intake drops due to fasting – above all with the electrolyte balance. Thought of in this order, the set is a sensible companion for mindful days.

Just as important as the fasting itself is the transition afterwards. Gently breaking the fast with easily digestible food, slowly increasing portion sizes, and continuing to drink enough all help the body readjust. Anyone who carries the mindfulness gained around eating and fullness into everyday life gets the most out of fasting. The set can accompany these phases, but it replaces neither mindful eating afterwards nor the fundamental decision of whether and for how long fasting is right for you. It's intended precisely as that kind of companion – targeted, honest, and complementary.

Frequently Asked Questions (FAQ)

Why Is Magnesium Important During Fasting?

During fasting, less is supplied through food, and the electrolyte balance moves into focus. Magnesium contributes to electrolyte balance, to normal muscle function, and to the reduction of tiredness – which is why the Magnesium Complex is the core building block.

Do the Supplements Break My Fast?

That depends on your form of fasting. Some products contain small amounts of additives or calories. Check the labels and decide according to how strict your fasting is. With pure water fasting, intake belongs under medical supervision.

Which Form of Magnesium Best Fits an Empty Stomach?

Many people find chelated Magnesium Bisglycinate particularly gentle on the stomach – handy when you're fasting on an empty stomach. Stick to the recommended intake.

Can I Use the Set with Intermittent Fasting?

With intermittent fasting, you can easily fit intake into your eating window. This way, you sidestep the question of whether a supplement breaks your fast.

Is Fasting Suitable for Everyone?

No. People with pre-existing conditions, pregnant women, breastfeeding women, and adolescents should seek medical advice before a fasting cure. The set does not replace this kind of guidance.

Note: Food supplements are not a substitute for a balanced diet and a healthy lifestyle. If you have an existing medical condition, are pregnant, breastfeeding, or taking medication, speak with your doctor before a fasting cure and before use.
