Berberine

What Is Berberine?

Berberine is a bright yellow alkaloid made by barberry, goldenseal, Oregon grape and coptis. This one comes from the bark of Berberis aristata, the Indian barberry, a thorny Himalayan shrub with yellow wood. It arrives here as berberine HCl, the salt form.

How It Works in the Body

Berberine is an isoquinoline alkaloid, a plant compound built around a nitrogen-containing ring and carrying a positive charge.

Its chemistry explains the format. A compound that resists water needs a carrier, so this softgel suspends the berberine in MCT oil, with capric acid in the mix.

What It Supports

• Glucose metabolism: Berberine supports glucose metabolism already in the normal range.
• A traditional bark: Berberis aristata bark — daruharidra — is a long-standing material in Ayurvedic practice.
• Medium-chain fats: Capric acid is a ten-carbon fat from MCT oil, and it plays a role in normal energy metabolism.
• A plant dye: Berberine-rich wood colored wool and leather long before anyone milled it into a supplement.
• Bitter by nature: Bitterness is berberine's signature, and bitter plants have a long place in herbal tradition.

Who It May Suit

It suits people who want a single, well-defined plant alkaloid rather than a blend, and who are comfortable with an oil-based softgel. That softgel is bovine gelatin, so it does not fit vegetarian or vegan eating.

Good To Know

Berberine asks for more caution than most botanicals. Talk with your healthcare provider before use if you take any prescription medication: berberine blocks CYP3A4 and P-glycoprotein, the enzyme and the transporter that clear much of what is prescribed, so it can raise drug levels in your blood. Do not use it if you are pregnant or nursing, since berberine reaches the infant and can displace bilirubin.
