What is Berberine?
Berberine is a plant alkaloid that stimulates cellular activity.
It’s harvested from various plants, trees, roots, and bark.
When sold in supplement form, berberine extract is dehydrated and ground to a fine powder stored in capsules.
Most berberine supplements have a distinct golden hue similar to ground turmeric, another popular Eastern spice taken for its anti-inflammatory benefits.
The healthful properties of berberine include its ability to stimulate glycolysis, a metabolic process that pulls usable energy from cells instead of storing it.
Berberine may also improve insulin secretion and sensitivity, which is vital for maintaining healthy blood sugar levels.
Taking berberine and following other evidence-based practices can help you improve your health.
Potential Benefits of Berberine
Health scientists continue to research berberine for its potential benefits in:
- Weight management.
- Cancer prevention.
- Improved cholesterol.
- Better blood sugar levels.
- Reducing inflammation.
- Helping to restore the gut microbiome.
- Neuroprotective activity.
So far, the outcomes look very promising. However, no single supplement will resolve health conditions or improve symptoms overnight.
You should use berberine while following the directions of your healthcare team to maximize potential benefits.
How To Choose the Right Berberine Supplement
There are many different supplements on the market.
Ideally, you should choose a product that can meet these criteria:
- It has excellent bioavailability, meaning your body will absorb as much of the supplement as possible.
- It comes from a reliable brand.
- Independent third-party labs have validated the formula.
- The dosage is supported by scientific research.
It is essential to be diligent about your supplement choices.
Supplements can be costly, and you want to ensure you get the best quality ingredients.
2023 research demonstrates that many berberine supplements on the market are less potent than marketed.
Only 56% of the 18 berberine supplements analyzed in the study contained the advertised amount of berberine.
Unfortunately, this happens frequently in the US because supplements aren’t regulated and don’t need to satisfy FDA protocols.

Taking The Correct Dosage
There are no published guidelines on the correct dosage of Berberine.
Research from 2023 has demonstrated positive health changes in people after taking between 1000 mg and 1500 mg of berberine daily for a minimum of three months.
The time it takes to see results varies by person.
Many of the supplement brands suggest taking three 500 mg capsules daily, which equates to 1500 mg total.
In some people, berberine may affect their gastrointestinal system and lead to diarrhea or constipation, stomach pain, and flatulence.
If you have a sensitive stomach, you may need a lower dosage. Your dietitian can help you make adjustments.
