Natural Detox: How to support the body’s cleansing processes in 21 days

8 min. reading

In the modern world, we are exposed to more than 80,000 different chemicals every day, and the average adult has at least 700 stored in their body.

Natural detoxification is not a fashion trend, but a vital function that runs continuously in our bodies.

By properly supporting the detoxifying organs – liver, kidneys, intestines, lymphatic system, lungs and skin – we can significantly improve energy, immunity and vitality.

Detoxification is one of the most important processes for staying healthy, but it is often misunderstood. It is a natural, continuous process that happens in your body 24/7, not just during “detox diets”.

What is natural detoxification and how does it work?

Natural detoxification (metabolic detoxification) is a biological process by which the body identifies, metabolises and eliminates substances that could upset its internal balance. It is a complex system of enzymatic reactions involving many organs – mainly the liver, kidneys, digestive tract, lymphatic system, skin and lungs. Together, they act as a sophisticated biological filter that maintains homeostasis.

The main detoxifying organs

1. The liver
It is the main biochemical centre of detoxification. It is the site of the three phases of toxin metabolism – from activation to neutralisation and excretion. They need amino acids, antioxidants, vitamins and minerals to function optimally.

2. Kidneys
The kidneys filter about 180 litres of blood every day and excrete water-soluble metabolites and toxins in the urine. To function well, they need adequate hydration, mineral balance and a minimum of excess medication or unhealthy diet.

3. The digestive system
The stomach, intestines and microbiota are the first line of defence against toxins from food. In the gut, excretion through faeces is crucial – but only if digestion and peristalsis are balanced.

4. The lymphatic system
It acts as a transport and purification system for waste substances, cellular debris and inflammatory mediators (molecules involved in inflammatory processes). Since it has no pump of its own, it is stimulated by movement, breathing, massage and proper hydration.

5. Skin
It is the largest organ of the body, acting as both a protective barrier and an excretory organ. It removes water-soluble substances such as urea, ammonia and some metals by sweating. Its condition often reflects the body’s internal balance.

6. Lungs
They are involved in the excretion of volatile compounds and metabolic products such as carbon dioxide and acetone. They also regulate the acid-base balance and link respiratory processes to the functioning of the nervous system.

Toxic body burden - where are the everyday toxins hiding?

The modern environment brings stresses that often exceed the body’s detoxifying capacity.

Traces of hundreds of chemicals can be found in the blood of the average adult.
Most people have at least seven different pesticides in their urine.
A study (Environmental Working Group, 2005) found 287 industrial chemicals in the umbilical cord blood of newborns, more than 200 of which are neurotoxic.

The most common sources of toxins:

pesticides, herbicides, mycotoxins (moulds),
heavy metals: lead, cadmium, mercury,
plasticisers (BPA, phthalates) in plastics and packaging,
Preservatives and additives in food,
air pollutants and exhaust fumes,
fragrances, perfumes, cosmetics and cleaning products.

How to identify overloaded detoxifying organs?

Many symptoms that are often treated in isolation can be the result of an overloaded detoxification system. In modern medicine, they are often treated symptomatically – without addressing the real cause.

The most common signs of an overloaded detoxification system:

chronic fatigue (up to 80% of people with liver dysfunction),
slow digestion and bloating, especially after fatty meals,
skin problems: rashes, itching, redness, eczema,
mood disorders: irritability, anxiety, foggy head,
Sleep disturbances: difficulty falling asleep or waking up early,
Hormonal imbalances: PMS, irregular periods, fluid retention,
hypersensitivity to alcohol, medicines, synthetic fragrances,
a bitter taste in the mouth, especially in the morning.

If you are experiencing several of these symptoms at the same time, there is a good chance that your detoxifying organs need extra support – through diet, exercise or targeted nutritional support.

The liver is key to this – for more on liver health, see the blog:

Hormones and weight loss: the hidden conductors of metabolism

Calories and exercise play a role in weight loss, but they are not the whole story. It is often the case that, despite carefully planned diets and regular exercise, results do not happen. One reason for this may be a hormonal imbalance that determines whether fat is used up or stored.

How hormones affect weight:

insulin – stable levels allow for better fat burning,
leptin – the satiety hormone that tells the brain when enough is enough,
Thyroid hormones – regulate the metabolic rate,
cortisol – a stress hormone that, in excess, promotes fat accumulation.

Natural ways to support hormonal balance:

time-limited feeding (14-16 hours of fasting),
quality sleep (7-9 hours, preferably before midnight),
stress management (meditation, yoga, nature walks),
regular physical activity (a combination of strength training and aerobic exercise).

Hormones are therefore the “hidden conductors” that can determine whether a diet works or not – so optimising them is key to long-term weight loss.

8 natural strategies for optimal detoxification

Once you understand your body’s signals and recognise the need for support, it’s time to take active action. The following strategies are based on a modern understanding of how the body works and focus on supporting natural processes rather than forcing them to speed up.

1. The three phases of liver detoxification – holistic support

The liver is the main biochemical centre of detoxification. To safely remove harmful substances from the body, they work in three successive phases. If there is an imbalance (e.g. activated phase I without adequate support from phase II), oxidative stress can increase. Therefore, coordinated support of all three phases simultaneously is essential.

Phase I – Biotransformation
Converts fat-soluble toxins into reactive compounds that are more water-soluble, but often temporarily more toxic.
Support: milk thistle, artichoke, green tea, broccoli, alpha-lipoic acid.

Phase II – Conjugation
Reactive compounds bind to molecules such as glutathione, amino acids and sulphates, allowing them to be neutralised and prepared for excretion.
Support: NAC, L-methionine, glycine, taurine, choline, B vitamins.

Phase III – Excretion
Conjugated substances are excreted from the liver cells into the bile or blood by means of transport proteins, and from there on out of the body in the urine and faeces.
Support: vitamin C, vitamin E, selenium, molybdenum, magnesium, phosphatidylserine.

2. Anti-inflammatory diet for detoxification

The cornerstone of successful detoxification is a diet that does not stress the detoxifying organs while providing essential nutrients. Anti-inflammatory foods reduce oxidative stress, strengthen the gut microbiome and support natural metabolic pathways.

Foods that support detoxification:

cruciferous vegetables (broccoli, kale, cauliflower) – activate detoxifying enzymes
green leafy vegetables – source of folate and magnesium
berries (blueberries, raspberries) – rich in antioxidants
oily fish (2-3 times a week) – a source of omega-3 fatty acids
Fermented foods – strengthen the gut microbiome
Citrus fruits – vitamin C for glutathione regeneration

Foods to avoid during detoxification:

processed foods with additives
sugar and artificial sweeteners
trans fats and oxidised oils
alcohol
industrially processed meat

3. Hydration and kidney support

The kidneys play a central role in the elimination of water-soluble toxins and metabolic waste. These “natural filters” filter around 180 litres of blood every day, regulating electrolyte balance, acid-base balance and the excretion of waste substances in the urine. Without adequate hydration, the kidneys cannot function optimally, which can lead to the accumulation of toxins and put additional strain on other detoxifying organs.

Optimal hydration:

30-35 ml of water per kilogram of body weight per day
2 glasses of warm water with lemon in the morning on a fasting diet
green tea – 2-3 cups daily
herbal teas (dandelion, spotted knapweed, St John’s wort)

Natural diuretics:

asparagus, leek, parsley
watermelon, cucumber
birch leaf tea

4. Activation of the lymphatic system

The lymphatic system acts as a transport and purification network, removing cellular waste, toxins and pathogens. As it has no pump of its own, regular exercise and external stimulation are essential for its function. When lymphatic flow slows down, toxins and inflammatory substances can build up, putting a strain on regeneration and weakening immunity.

Techniques to stimulate lymphatic flow:

dry brushing – 5 minutes before showering
lymphatic massage – gentle pressure against the heart
Trampoline exercises – 10-15 minutes per day
Deep breathing – supports the movement of lymph in the chest
yoga in inverted poses – gravity helps further

5. A healthy gut as the first line of detoxification

The gut is the first line of defence against toxins. Its lining acts as a selective filter: it lets in beneficial nutrients while keeping out harmful substances and bacteria. When the barrier becomes damaged, a condition known as ‘leaky gut’ occurs, which allows toxins to enter the bloodstream and can trigger chronic inflammation.

Strategies for a healthy gut:

prebiotics – fibre that feeds beneficial bacteria
fermented foods – kefir, sauerkraut, kombucha
selected amino acids (e.g. L-glutamine) – support the repair of the intestinal mucosa
regular discharge – at least 1-2 times a day

Toxin binding and excretion:

Activated charcoal – helps reduce bloating after meals
soluble fibre (psyllium, pectin) – supports intestinal secretion
Modified citrus pectin – aids binding and excretion
Silicon (e.g. from horsetail extract) – supports connective tissue metabolism and binding of substances

6. Detoxification through the skin

The skin is the largest excretory organ, with more than 2 million sweat glands. Water-soluble toxins, metabolic wastes and some heavy metals are excreted through sweat, while a healthy skin barrier protects against the intrusion of harmful substances.

Methods to support detoxification through the skin:

infrared sauna – 15-30 minutes, 3-5 times a week
Epsom salt bath – 2 cups salt, 20 minutes
sweating with exercise – naturally stimulates secretion
dry brushing – stimulates lymphatic flow and blood circulation
cold showers – boost circulation and skin vitality

7. The importance of quality sleep for detoxification and recovery

During sleep, the body carries out its most important repair processes. During the deep stages of sleep, the glymphatic system is activated, removing toxins from the brain tissue, while at the same time increasing the secretion of growth hormone, which stimulates the regeneration of cells throughout the body.

Rules for quality sleep:

sleep before 22:30 – the liver is most active between 1:00 and 3:00
total darkness – stimulates melatonin production
room temperature 18-20 °C
no screens for at least 2 hours before bedtime
deep sleep allows for glymphatic drainage of the brain

8. Stress and cortisol management

Prolonged stress inhibits natural detoxification processes and increases inflammation. Elevated cortisol diverts the body’s resources away from repair and detoxification, triggering responses that put additional strain on the organs. This results in a faster depletion of magnesium stores and B vitamins, which are important for the function of detoxifying enzymes.

Stress reduction techniques:

meditation – 10-20 minutes a day
breathing exercises – method 4-7-8
Walking in nature – proven to lower cortisol by up to 30%
yoga – combining movement and mindfulness
regular daily rhythm – stabilises the circadian cycle

Frequently asked questions

How long does natural detoxification take?
The first improvements, such as better digestion or more energy, can be seen within 3-7 days. More noticeable changes usually occur within 2-4 weeks, while deep detoxification can take 3-6 months – depending on the level of toxic burden and lifestyle.

Can I detox during pregnancy?
Intensive detoxification programmes are not recommended during pregnancy and breastfeeding, as they can trigger the release of toxins into the bloodstream. During this period it is safe to support the body with a balanced diet, sufficient fluids and gentle digestive measures.

Which reactions are normal during detoxification?
In the initial phase, you may experience mild symptoms such as headache, fatigue or changes in digestion. This is the body’s normal response to the mobilisation of toxins. Symptoms usually resolve within 3-5 days; however, if they persist longer or intensify, a consultation with a specialist is recommended.

Can I take medication during detoxification?
If you are taking medication, always consult your doctor or pharmacist before starting a detox. Some nutrients used to support detoxification can interfere with liver enzymes and thus with the metabolism of medicines.

How often should I detox?
Natural detoxification should be part of your ongoing support – through a balanced diet, exercise, hydration and quality sleep. Targeted programmes (e.g. 21-day protocols) can be carried out 2-4 times a year, depending on lifestyle and level of exposure.

When to see a doctor?
Contact your doctor if you experience:

severe fatigue lasting more than a week,
severe headaches or dizziness,
skin rashes or allergic reactions,
indigestion with vomiting,
unusual or severe pain.
