Anyone who wants to curb cravings, support healthy weight loss, and balance blood sugar naturally — without injections or extreme diets. It boosts your body's own GLP-1 and AMPK production, which decline with age.
A clinically-studied dose of berberine extract paired with milk thistle for maximum absorption. Most berberine supplements fail because your body only absorbs about 5% — pairing it with milk thistle boosts absorption for best results.
Results compound over time, with the best benefits showing between 3-6 months. We recommend the 3 or 6-bottle bundle for lasting results and the biggest savings.
Take 1 capsule twice per day, before meals, at the same times each day.
Yes! Popular pairings include CinnaChroma for blood sugar support and Fiber Greens for gut health. Check with your healthcare provider if you're on any medications.

Why Berberine?

Berberine is an advanced metabolic health supplement designed to support healthy blood sugar, weight management, and overall wellness.

Research shows berberine can help support healthy blood sugar and metabolic function – but getting enough, and absorbing it properly, can be a challenge.

That’s why we’ve combined a clinically-studied dose of berberine with milk thistle. Milk thistle helps boost berberine absorption so your body can use this powerful nutrient to its full potential.

This simple, effective formula was carefully developed by our in-house Doctor of Integrative Medicine to help you experience the powerful health benefits of berberine in your everyday life.

How To Use Berberine

Take 2 small capsules (one serving) daily to support metabolic health, blood sugar, and total body wellness.

What’s Inside Berberine?

Meet the science-backed ingredients that power Berberine and make it a favorite for those seeking better metabolic and total-body health.

Berberine is a time-tested natural compound, traditionally used to support healthy blood sugar, cholesterol, and metabolism.

Modern research shows that berberine activates AMPK – a crucial enzyme that helps your body process glucose and fat, promoting balanced blood sugar and weight management.

Our supplement includes a clinically studied dose of berberine, giving you meaningful support for healthy blood sugar, metabolism, and overall wellness.

Myths About Metabolism

  • Myth Supplements don’t help you lose weight

    Reality

    While no supplement can replace a healthy lifestyle, the right nutrients can absolutely support weight management. Berberine has been shown to help regulate blood sugar, boost metabolism, and improve insulin sensitivity, all key factors that help your body to burn fat and maintain a healthy weight.

  • Myth Metabolism slows down with age and you can’t do anything about it

    Reality

    While metabolism naturally changes as we get older, it doesn’t have to slow down. Research shows that supporting blood sugar balance, insulin sensitivity, and healthy cellular energy can keep your metabolism working efficiently. Berberine activates AMPK, often called your body’s “metabolic master switch,” helping to support a healthy metabolism at any age.

  • Myth A slow metabolism 
is genetic

    Reality

    Genetics can play a role, but they aren’t your destiny. Lifestyle choices, diet, sleep, and nutrient intake all have a huge impact on metabolism. Berberine helps address one of the most common metabolic roadblocks by supporting healthy insulin sensitivity and activating key enzymes that help your body use energy more effectively.

  • Myth You can get berberine from food sources

    Reality

    Berberine is very rare and it isn’t in any foods we eat regularly. It’s best to get berberine through a supplement that has both a clinically backed dose and a nutrient to help boost absorption, like the milk thistle ingredient in our formula.
