Adults with type 2 diabetes who are taking diabetes medication need to speak to their doctor before trying berberine. Also, it may not be safe for people who are on blood sugar, blood lipid, blood clotting, and blood pressure medications (thus, consult with your doctor first if you're on these medications).
Berberine might slow blood clotting and increase the risk of bleeding. Taking it with other supplements with similar effects might increase the risk of bleeding in some people. Examples of supplements with this effect include garlic, ginger, ginkgo, nattokinase, and Panax ginseng.
The standard dose of berberine is 900-2,000mg a day, divided into three to four doses. 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.
The toxicity of pure compound is greater than the toxicity of plant extract or plant extract fractions. The sub-acute concentrations of berberine lead to altered liver function, gastric troubles, hepato and hematotoxicity, hemorrhagic inflammatory consequences, damage to immune cells and induced apoptosis.
Taking berberine supplements regularly appears to lower total cholesterol, “bad” cholesterol, and triglycerides in people with high cholesterol. It works differently from today's standard cholesterol medications, so it may help treat people who are resistant to other cholesterol-lowering drugs.
The mechanism for berberine extract is very unclear. For decades it has been a well-researched herbal treatment for intestinal infections, like Giardia, but it came with the warning to avoid long-term use due to the potential undesirable and antimicrobial effect in the gut.
How long should I take berberine? Continual use of berberine can impact cytochrome P450 (CYP) enzymes in the liver which may affect drug-to-drug interactions. Therefore, it's recommended to use it in a pulsed 8-week cycle with two to four weeks off, then starting again if symptoms have not resolved.
Research has suggested that berberine can help treat diabetes, obesity, and inflammation, among other conditions. However, side effects can include upset stomach and nausea. Berberine has been a part of Chinese and Ayurvedic medicine for thousands of years.
Berberine has great potential in treatment of insomnia and might have better clinical significance.
The effects of berberine are not immediately felt if you take it for only a few days. Instead, taking it for more extended periods is necessary to see its effects. Some studies suggest that berberine's effects can be seen when taking supplements for at least three months.
The recommended dosage of berberine is 500 mg three times a day. It should be taken half an hour before meals. It does not cause severe side effects, so taking it on an empty stomach should be ok. But be careful, as it can cause some stomach problems.
Early research suggests that taking berberine together with vitamin D3, vitamin K, and a chemical found in hops for 14 weeks can decrease bone loss in postmenopausal women with osteoporosis.
Constipation. Gas. Upset stomach. Hypoglycemia or low blood sugar levels (This can happen especially if other blood sugar lowering medications are being taken in addition to berberine, explains Davis.)
Emerging research suggests that berberine is beneficial for balancing hormones, especially when it comes to polycystic ovary syndrome (PCOS). Berberine provides numerous benefits for women living with PCOS, including improved fertility, weight loss, and reduced inflammation.
The supplement should be taken with dinner or at bedtime. Your healthcare provider may increase your berberine dosage to 500 mg twice daily with meals. Sometimes, doctors advise taking berberine 500 mg three times a day.
Berberine (also known as berberine hydrochloride) is a natural isoquinoline alkaloid found in a wide variety of herbs, including goldenseal, barberry, goldthread, Oregon grape and tree turmeric.
Recent research has shown that berberine has an effect of protecting heart failure, hypertension, hyperlipidemia, insulin resistance, arrhythmias, and platelet aggregation.
Recent evidence suggests that berberine inhibits the production of neuroinflammation, oxidative, and endoplasmic reticulum stress. These effects can further reduce neuron damage and apoptosis.
While there is limited scientific research specifically focused on the timeline for berberine's effectiveness in weight loss, some studies have indicated that it may produce noticeable results within a few weeks to a few months.
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.
Depending on how healthy a patient's liver is, berberine's beneficial effects can persist for as long as 20 hours, meaning that a once-per-day dosing schedule is sufficient for most patients. When taken once per day, berberine is safe to take for at least 12 months.
Caffeine is also a planar molecule which may interfere with the effectiveness of anti-cancer intercalating agents such as berberine by directly binding with the drug and preventing it from targeting the DNA of cancer cells.
