Supports the liver at a physiological level, not detoxification
According to Dr. Mark Hyman, a functional medicine doctor, lecturer at the Cleveland Clinic (USA) Center for Functional Medicine, lemon juice can bring indirect benefits to the liver, mainly through improving hydration and providing antioxidants.
“Gan is the body's natural detoxifying organ. There is no water to cleanse the liver, but drinking enough water and supplementing with vitamin C can help the liver function more effectively,” Mr. Hyman said.
Lemons contain vitamin C and flavonoids, plant compounds that can neutralize free radicals produced during metabolism. When oxidative stress is reduced, liver cells are less damaged, thereby helping the liver maintain stable function.
Indirect, non-therapeutic impact on liver fat
Some observational studies show that flavonoids in citrus fruits can support lipid metabolism regulation, contributing to limiting fat accumulation in the liver. However, experts affirm that this is only a supporting effect.
According to Dr. Elizabeth Boham, a clinical nutritionist at UltraWellness Center (USA), lemon juice is not likely to reduce liver fat if it is not accompanied by weight loss and lifestyle changes. “A lighter feeling of liver usually comes from reducing sugary drinks, alcohol and increasing water intake, not from the acid in lemon,” Ms. Boham said.
Antioxidants and protect liver cells
Vitamin C and flavonoids are antioxidants that have been shown to protect liver cells from the effects of alcohol, environmental pollution and a high-fat diet. In addition, limonin, a natural compound in lemon, is recorded to have the ability to reduce inflammatory and oxidative stress responses in the liver.
However, experts note: this effect is preventive and has no value in treating chronic liver diseases.
Citric acid in lemon stimulates gastric juice secretion, supporting fat digestion. When the digestive system works effectively, the liver reduces pressure to process lipids and metabolic products. This is why many people feel more comfortable when drinking diluted lemon juice.
However, this benefit does not mean that lemon juice cleans the liver and gallbladder as advertised on social networks.
How to drink it without adverse effects
International nutrition experts recommend drinking only diluted lemon juice, preferably after meals or in the morning, but not on an empty stomach. Drinking thick lemon juice can cause stomach irritation, tooth enamel erosion and worsen the symptoms of reflux.
In particular, people with liver and stomach diseases or who are taking liver-transmitting drugs should consult a doctor before maintaining this habit.
Lemon juice can be a healthy choice in daily life, but not a liver treatment method. For liver health, scientific lifestyle is still the most important medicine.
