Berberine has been used in ancient Chinese and Indian medicine since 200 A.D. [1] it's commonly prescribed in a medical setting as an antibiotic for bacterial diarrhea, intestinal parasite infections, and certain eye infections. [3] it's also may be prescribed to manage diabetes, high blood sugar, or lipid levels. [4]
This article will discuss berberine recommended dose, use, benefits, and frequently asked questions.
Berberine Recommended Dosage & Use
Berberine hydrochloride is the most common form of berberine used in both supplements and over-the-counter medications. [2] You can also find and consume berberine in sulfate, citrate, and phosphate forms. [1]Consume 900 to 2,000mg of berberine daily with or immediately after a meal, split into 3 or 4 doses to maximize the benefits and minimize the side effects. [5] A dose of 900 to 1,200mg is used to treat diarrhea and a dose of 500mg taken three times per day is used to manage diabetes in adults. [6][5]
To assess tolerance begin with the lowest recommended dose and adjust up or down depending on your body's response. While berberine is generally well tolerated in healthy individuals, consult with your physician or health care professional if you're using daily prescription medications affecting the brain, heart, liver, or blood.
A Deeper Look at Berberine Benefits
Berberine has glucose and lipid metabolism regulating properties that rival prescription medications. Metformin is a well-known prescription drug used in diabetics to control blood sugar. When 36 type-2 diabetic adults consumed either 500mg of berberine or metformin three times per day for 3 months, both groups experienced similar statistically significant decreases in hemoglobin A1c, fasting blood glucose, post-meal blood glucose, and triglyceride blood levels. [2]
These findings are extremely promising for those looking to use natural compounds to control blood sugar. A second study dosed 48 type-2 diabetic adults with berberine for three months and found it significantly lowered fasting blood glucose, post-meal blood glucose, hemoglobin A1c, total cholesterol, and LDL (bad) cholesterol. [2]
When 12 patients with metabolic syndrome consumed 500mg of berberine three per day for three months, 36% of patients no longer had metabolic syndrome while all lowered their systolic blood pressure, triglycerides, glucose levels, insulin levels, and insulinogenic index. [7] A fourth study of 58 type 2 diabetic patients dosing berberine at 1,000mg per day further the supported the beneficial impact discussed above as well as found berberine to be effective at increasing glucose disposal rate. [4] Berberine might just be the best natural compound for managing Type-2 Diabetes.
Berberine is also effective in treating non-alcoholic fatty liver disease (NAFLD), a condition arising from the extended excessive consumption of high-calorie foods. As a result, normal lipid metabolism is impaired or altered. [8] Combined with lifestyle intervention berberine reduced liver fat content by over 50% and is more effective than pioglitazone, a popular drug prescribed to Type 2 diabetics, in decreasing body weight and improving lipid profile. [9]
Berberine decreases liver fat by counteracting the impaired function of MTTP, a gene used to make microsomal triglyceride transfer protein. [8][10] A study of 144 adults consuming 500mg of berberine twice per day significantly decreased body weight, BMI, cholesterol, and triglycerides over placebo. [11] These findings further support the use of berberine in diabetic and obese individuals.
Berberine has a strong positive effect on the brain and may protect against Alzheimer's, cerebral ischemia, mental depression, schizophrenia and anxiety. [12] Daily berberine administration of 5mg/kg of bodyweight in mice for 15 days increased norepinephrine by 29%, serotonin by 19%, and dopamine by 52%. [13]
Norepinephrine, is the neurotransmitter responsible for the fight-or-flight while serotonin and dopamine are neurotransmitters commonly classified as "feel-good" hormones. When researchers doubled the dose of berberine to 10mg/kg serotonin and dopamine significantly increased but norepinephrine did not. [13] These findings offer promise for may greatly alleviate or reverse the effects of certain psychological disorders.
Berberine's anti-cancer effects are profound. Berberine inhibits and decreases activator protein 1 (AP-1) binding in cancer cells. [14] AP-1 plays a significant role in increasing the size and number of cancer cells in the body. Berberine also stops the cell cycle and promotes programmed cell death in cancerous liver cells. [15]
Berberine even appears to directly target cancerous cells up to 24 hours after post-consumption. [16] The compound also works synergistically with chemotherapeutic drugs to increase the body sensitivity during treatment. [17] While berberine may not be the cure for cancer it does appear to slow or stop cancer cell growth.
Berberine exhibits powerful anti-inflammatory and cardioprotective benefits. The compound prevents pro-inflammatory cytokines, proteins used for cell signaling. [18] Keeping inflammatory proteins low minimizes your risk for infection and many diseases.
When 14 healthy individuals consumed 1,200mg of berberine per day for 30 days they experienced a significant decline in circulating endothelial microparticles (EMPs). [19] Excessively high EMPs suggest a higher likelihood of vascular disease development as well as issues related to the inner lining of blood vessels.
Berberine accomplishes this by activating the 5' AMP-activated protein kinase (AMPK) signaling cascade. [20] A study of 79 patients with chronic congestive heart failure received 1,200mg to 2,000mg of berberine per day experienced greater left ventricular ejection fraction and exercise capacity as well as fewer and less intense ventricular premature complexes compared to placebo. [21]
Those with high inflammation and heart conditions may benefit greatly from berberine when used in conjunction with diet, exercise, and prescription medications.
Berberine FAQs
Does Berberine have any side effects?
Unlike other natural compounds with pharmaceutical-grade effects, Berberine and its sources have low toxicity and no reports of serious side effects. [22][23] One study on 48 type-2 diabetic adults found that 35% of the patients experienced momentary and short-lived gastrointestinal issues. [2]
Spread your berberine dose out in to 3 or 4 smaller doses throughout the day to minimize the likelihood of cramps or diarrhea. A second study reported that 5 of 58 type-2 diabetic patients experienced mild or moderate constipation. [4]
Short-term (<1 year) berberine consumption has no negative impact on kidney or liver function. [2] While data related to long-term (>1 year) berberine use is limited, experts don't advise against taking this compound long-term.
Is Berberine safe to stack with other supplements?
Berberine is safe to stack with staple supplements like fish oil, whey protein, multivitamins, creatine, BCAAs, and caffeine. Stack berberine with sodium caprate or p-glycoprotein inhibitors like milk thistle to increase absorption.5 Milk thistle also has strong liver-protective properties. [5]
Do NOT combine berberine with phosphodiesterase (PDE) inhibitors as their fat-burning properties will be reduced. Berberine has a high interaction-potential with certain medication.
Do NOT combine berberine with macrolide antibiotics like azithromycin, compounds interacting with enzymes CYP2D6, CYP2C9, and CYP3A4, organic anion transporter proteins. [5] Do NOT stack berberine with Type-2 Diabetes prescription drugs like metformin. A healthy individual regularly using moderate doses of berberine should experience numerous benefits with little to no side effects.
