While berberine is generally well-tolerated and may even benefit liver health by reducing inflammation and fatty liver, high doses or prolonged use could potentially impact liver function or interfere with liver enzymes, especially in susceptible individuals or those with pre-existing liver conditions, though clinically apparent liver injury is rare. It can inhibit certain liver enzymes, affecting drug metabolism, so consulting a doctor is crucial before taking it.
Studies suggest that berberine does not damage the liver. Some research suggests that berberine may enhance liver health, lower inflammation in the liver, and potentially treat non-alcoholic fatty liver disease. But other research shows that berberine hinders certain liver enzymes involved in metabolizing drugs.
Berberine and kidney function
Another study shows that berberine can impact your gut health, which results in a reduction of substances that can make kidney disease worse. But it's important to note, again, that more research is needed to fully understand how berberine can affect your kidneys.
Berberine may be safe when taken in recommended amounts — with the exceptions that it should not be used by children or people who are pregnant or breastfeeding. The main side effects of berberine are gastrointestinal (GI) and include nausea, constipation, diarrhea, gas and vomiting.
Because berberine may cause an increase in uterine activity, it is not recommended for use in pregnancy. Berberine crosses the placenta and may cause harm to the developing fetus. Berberine is also transferred through human milk and should be used with caution during lactation.
Should you take myo-inositol or berberine? Myo-inositol works better for periods, ovulation, and fertility in PCOS with fewer side effects. Berberine may be better for helping reduce belly fat, LDL cholesterol, and blood sugar levels, but it is not recommended during pregnancy or breastfeeding.
Do Any Foods Contain Berberine? Berberine is not found in any common food sources. As mentioned, it's derived from the roots, stems, and bark of plants such as barberry, Chinese goldthread, goldenseal, tree turmeric, and Oregon grape. Therefore, if you try berberine, it's best to get it from a supplement.
The prohibition on the use of berberine, as controlled under the Poisons Act, was implemented in 1978 arising from local safety concerns that berberine could cause severe jaundice and brain damage in glucose-6-phosphate dehydrogenase (G6PD) deficient babies.
When taken by mouth: Berberine is possibly safe for most adults. It's been used safely in doses up to 1.5 grams daily for 6 months. Common side effects include diarrhea, constipation, gas, and upset stomach. When applied to the skin: Berberine is possibly safe for most adults when used short-term.
Berberine can interact with some medications, including statins, anti-tumor medications and pain relievers such as acetaminophen (Tylenol), blood thinners such as warfarin or medicines that cause drowsiness or sedation. You need to be cautious if you're also taking a potentially toxic medicine such as cyclosporine.
No, berberine and turmeric are not the same; berberine is a compound found in plants like barberry, while curcumin is the active compound in the spice turmeric, though both are plant-derived phytochemicals known for antioxidant, anti-inflammatory properties, and supporting gut health, often used in traditional medicine and supplements, but they have different chemical structures and primary actions, with berberine often focusing on metabolic health (like blood sugar/cholesterol) and curcumin on inflammation, notes Tesseract Medical Research and Wellbeing Nutrition.
The study demonstrates that sodium caprate could significantly promote the absorption of berberine in intestine and enhance its antidiabetic effect without any serious mucosal damage.
Short-term exposure to berberine alters the populations of intestinal bacteria by reducing the activity of Clostridium cluster XIVa and IV, and their bile salt hydrolase (BSH), thus leading to the accumulation of taurocholic acid (TCA).
The three worst things for your liver are excessive alcohol, a diet high in added sugars, unhealthy fats, and salt (processed/fast foods), and overuse of certain medications (like acetaminophen/paracetamol), all leading to fat buildup (fatty liver), inflammation, and potential severe damage like cirrhosis, though lifestyle changes can often reverse early stages.
The fastest way to repair your liver involves immediate lifestyle changes: stop alcohol/smoking, adopt a healthy diet (whole foods, less sugar/fat/processed items), manage weight/exercise, and avoid liver-harming medications, all while consulting a doctor for personalized guidance, as severe damage needs medical intervention for reversal.
Some alcohol-related liver damage can be reversed if you stop drinking alcohol early enough in the disease process. Healing can begin as early as a few days to weeks after you stop drinking, but if the damage is severe, healing can take several months.
Yes, studies suggest berberine can help reduce belly fat, often by improving metabolism, lowering blood sugar, reducing insulin resistance, and inhibiting fat cell growth, but it's not a magic pill; it works best alongside a healthy diet, exercise, and stress management for significant results, potentially leading to modest weight loss.
Berberine is considered safe for most people at dosages up to 1,500 mg per day. Berberine might not be safe for some adults, including people who have liver or kidney problems. You should also avoid berberine if you're pregnant or breastfeeding.
Studies have shown that berberine is safe in doses up to 1.5 grams daily over a period of 6 months to 2 years. However, many products on the market exceed recommended doses, offering up to 3 grams daily. Common dosages include 500 mg of berberine three times per day and before meals.
Our Top Picks for Berberine Supplements
Berberine should be taken with a meal, or shortly after, to take advantage of the blood glucose and lipid spike associated with eating. Too much berberine at once can result in stomach upset, cramping, and diarrhea.
Standard doses of berberine are generally well tolerated and eventual adverse events are rare and mild. On the contrary, high doses have been associated with arterial hypotension, dyspnea, flu-like symptoms, gastrointestinal discomfort, constipation, and cardiac damage.
Berberine can interact with prescription medications and increase or decrease levels of these medicines in the blood due to its effects on specific enzymes in the blood. This is especially true of drugs like metformin metabolized by the liver. There may also be an increased risk of bleeding.
No, berberine and turmeric are not the same; berberine is a compound found in plants like barberry, while curcumin is the active compound in the spice turmeric, though both are plant-derived phytochemicals known for antioxidant, anti-inflammatory properties, and supporting gut health, often used in traditional medicine and supplements, but they have different chemical structures and primary actions, with berberine often focusing on metabolic health (like blood sugar/cholesterol) and curcumin on inflammation, notes Tesseract Medical Research and Wellbeing Nutrition.
The genus Berberis is well-known as the most widely distributed natural source of berberine. The bark of B. vulgaris contains more than 8% of alkaloids, berberine being the major alkaloid (about 5%) (Arayne et al., 2007).
