What is berberine?

Berberine is a naturally occurring alkaloid found in traditional botanicals such as barberry (Berberis), goldenseal, and Coptis. It’s been used in traditional systems for centuries and today is available in capsules, powders and tinctures. Many modern products use berberine HCl for consistent potency.

Top potential benefits (what people take it for)

(Evidence-informed but not medical advice; individual responses vary.)

1) Metabolic support (blood sugar & insulin sensitivity)

Berberine is commonly used to support healthy glucose metabolism and insulin sensitivity, making it a popular choice for people focused on metabolic wellbeing and steady energy.

2) Heart & cholesterol support

Many users choose berberine as part of a heart-healthy lifestyle because it supports healthy lipid profiles and normal circulation alongside diet and exercise.

3) Gut & microbiome balance

Berberine’s microbiome-modulating and traditional antimicrobial actions are often cited for digestive comfort and a balanced gut environment.

4) General wellness & vitality

Because berberine touches metabolic, cardiovascular, and gut domains, some people find it a useful option for broad, holistic wellbeing.
