Liver detoxification is a process that reduces toxin buildup within the body, particularly the liver. The liver contains enzymes that metabolize and filter out alcohol, drugs, and other toxins. Optimal liver health is vital for overall wellness, so it's beneficial to ensure the body’s detoxification process is efficient.
This article aims to help doctors and patients better understand detoxification and the signs that liver detox is working.

Understanding Liver Detoxes
Liver detox, or a liver cleanse, includes methods that enhance liver health and reduce toxin buildup within the body. Common reasons individuals seek liver detoxification include:
- Drinking too much alcohol
- Impaired liver health and function
- Medication or drug misuse
- Toxin exposure
- Being overweight
- Fatigue
- Poor sleep
- Diminished mental health or cognition
- Poor overall health and well-being
- Toxic hepatitis (liver inflammation)
Toxic hepatitis may result because of exposure to excess alcohol, drugs, prescription medications, dietary supplements, or chemicals. When left untreated, this form of hepatitis may eventually damage the liver and cause irreversible scarring.
Detoxification in the liver occurs in two phases. During phase 1, cytochrome enzymes activate drugs and toxins using various reactions, resulting in water-soluble metabolites. During phase 2, phase 1 end-products are neutralized during conjugation reactions. Specific molecules attach to them, making these products less harmful and eliminating them from the body.
Medical liver detoxification generally uses drugs or other therapies as a treatment in clinics or hospitals.
Natural detox methods often consist of diet and other lifestyle changes, such as fasting, drinking more water or tea, or taking dietary supplements. While some forms of liver detoxification simply involve making healthier lifestyle changes, others use more extreme methods.
Do Liver Detoxes Work?
Whether or not specific liver detoxes work is sometimes controversial.
Theoretical Basis for Liver Detox
A healthy liver detoxifies efficiently on its own, as long as an individual isn’t exposed to excessive amounts of drugs, alcohol, or other toxins. The liver processes and eliminates toxins naturally, but detoxification methods can enhance detox and the liver’s overall functioning.
Effectiveness of Liver Detox Programs
Studies have examined the effects of specific liver detox programs.
One study found that phytonutrients support the liver’s detox process by stimulating the production of detoxification enzymes or acting like antioxidants, diminishing harmful effects of free radicals. This detox program used a whole-food dietary supplement in the form of a shake and resulted in a 40% increase in cellular antioxidant capacity and enhanced phase 2 detoxification.
However, a review shows that while detox diets are popular for facilitating weight loss and toxin elimination, there is little clinical evidence to support such diets. The researchers found that some studies showed beneficial effects of detox diets on toxin elimination and improved liver health, while others had flawed methodologies.
Medical liver detoxification programs are effective for treating toxic hepatitis and its underlying causes.
The best solutions for improving liver health include adopting healthy lifestyle habits and seeking medical intervention for acute toxin exposure or liver disease.
Risks and Controversies
Potential risks, side effects, and dangers of extreme detox methods include:
- Drinking unpasteurized juices can cause foodborne illnesses.
- Consuming high amounts of high-oxalate juices may increase the risk of kidney problems.
- Following very restrictive diets can lead to malnutrition.
- Rapid weight loss from fasting can cause fatigue, weakness, faintness, dehydration, and gallstone formation.
- Using laxatives can lead to electrolyte imbalances and diarrhea.
- Drinking very large amounts of herbal tea or water can also cause dangerous electrolyte imbalances.
- Colon cleansing products may be harmful for people with a history of colon surgery, gastrointestinal (GI) diseases, kidney disease, heart disease, or severe hemorrhoids.
Medical supervision is vital when following a liver detox program. Some liver detoxification products requiring the use of dietary supplements can harm the liver by causing drug-induced liver injuries.
In fact, the Federal Trade Commission (FTC) and the U.S. Food and Drug Administration (FDA) have taken action against numerous companies for selling detox/cleanse products because they contain potentially harmful or illegal ingredients.
Because of these and other concerns, some people should avoid extreme detox diets — including those who are pregnant, trying to become pregnant, taking certain medications, or who have specific medical conditions. People with diabetes should not alter their diet without supervision by a healthcare provider.
How Is Liver Detox Typically Done?
Liver detox or cleanse programs typically involve one or more of the following methods:
- Eating only certain foods, such as cabbage soup or meal replacement shakes
- Drinking only water, juice, or tea
- Fasting
- Using dietary supplements or herbs
- Cleansing the colon with laxatives, enemas, or colon irrigation products
- Using a sauna or exercising more to increase sweating
- Reducing environmental toxin exposure
- Eating only whole, organic foods
- Eliminating added sugar and highly processed foods
- Taking medications during medical liver detoxification
Each liver detox program has specific protocols; not all of them have been studied for long-term safety and effectiveness.
A well-balanced diet and other healthy lifestyle changes are often key to effective liver detox programs.
When undergoing medically-based liver detoxification, guidance and supervision by a healthcare provider is crucial.
Signs That a Liver Detox Is Working
Signs liver detox is working to enhance liver health include:
Subjective Signs
- Improved energy
- Reduced fatigue
- Enhanced mental clarity
- Reduced brain fog
- Better digestion
- Regular urinary patterns and bowel movements
- Improved complexion
- Clearer skin
- Improved appetite
- Better sleep
- Less bloating
- Reduced signs of inflammation
- Fewer food cravings
- Better mood
- Feeling of wellness
Objective Signs
- Normal liver enzyme levels
- Healthy cholesterol levels
- Weight loss or healthy weight management
- Improvements in body composition
- Better inflammatory markers
Behavioral and Lifestyle Changes
- Adherence to medical advice and liver detox protocols
- Healthier diet
- Regular physical activity
- Decreased alcohol consumption
- Smoking cessation
- Working up a sweat regularly
- Drinking recommended amounts of water
Urine should be light yellow or clear to indicate good liver function and proper hydration. However, the urine may initially be darker during liver detox as toxins leave the body.
Signs of unhealthy liver function include constipation, dark urine, high blood pressure, gas, bloating, and heartburn. People with impaired liver function might experience chronic fatigue, difficulty losing weight, a poor appetite, mood changes, and excessive sweating. They may bruise easily or develop rosacea and other skin conditions.
Lab Tests to Perform Before Detox
Lab tests to perform before undergoing liver detoxification include:
Liver Function Tests (LFTs)
Common markers that assess liver function include:
- ALT (alanine aminotransferase)
- AST (aspartate aminotransferase)
- ALP (alkaline phosphatase)
- GGT (gamma-glutamyl transferase)
- Bilirubin
- Albumin and total protein
- L-lactate dehydrogenase (LD)
- Prothrombin time (PT)
The purpose of liver function tests is to assess liver health and detect any abnormalities.
Examples of typical blood test results for adult men with normal liver function include:
- Total protein: 6.3 to 7.9 g/dL
- ALT: 7 to 55 units per liter
- AST: 8 to 48 units per liter
- ALP: 40 to 129 units per liter
- Bilirubin: 0.1 to 1.2 mg/dL
- GGT: 8 to 61 units per liter
- LD: 122 to 222 units per liter
- PT: 9.4 to 12.5 seconds
- Albumin: 3.5 to 5.0 g/dL
Results for women and children may vary slightly from these levels.
Complete Blood Count (CBC)
CBC screens for infections, anemia, and other blood-related issues.
Comprehensive Metabolic Panel (CMP)
CMP provides information regarding electrolytes, kidney function, and other key markers.
Specific Tests for Underlying Conditions
Hepatitis labs and tests for drug or alcohol misuse, autoimmune conditions, genetic conditions, cancer, nonalcoholic fatty liver disease, and other causes of liver impairment can screen for underlying conditions based on individual risk factors.
Lab Tests After Liver Detox
Completing lab testing after liver detoxification assesses liver health and screens for signs liver detox is working.
Assessing Detox Outcomes
Compare post-detox lab test results with the initial tests to establish if liver health has improved. Evaluate liver function improvements and other health markers to determine if further treatment is needed to eliminate toxins, improve liver function, or prevent complications.
Confirming Safety and Health
It’s important to screen for adverse effects during and after a liver detox by addressing any ongoing concerns (including new or unusual symptoms). Routine lab tests may be needed for individuals with a history of liver problems or chronic diseases.
Planning Long-Term Health Strategies
Use lab test results to guide future lifestyle changes and medical treatments that optimize liver function and overall health. Patients should see their provider for routine health screenings and preventive measures.
Long-Term Strategies for Liver Health
Examples of long-term strategies for optional liver health include:
- Consume a balanced diet rich in antioxidants and fiber.
- Exercise regularly to work up a sweat.
- Drink plenty of water to maximize hydration.
- Limit or avoid alcohol.
- Avoid drugs and other liver-damaging substances.
