BERBERINE EXPLAINED · PUBLISHED BY COREVITAL · PRODUCT INFORMATION INCLUDED

Berberine & metabolism.
What does the research actually show?

From cellular energy signals to human studies: a clear guide to what researchers have measured, what remains uncertain, and where a daily routine fits.

Start with the science. Compare the evidence. Then explore the reasoning behind CoreVital Burn’s five-botanical formula and 30 days of guidance.

01 / START WITH THE SYSTEM

Metabolism is more than a single switch.

It is how your body transforms, stores and uses energy.

Food supplies building blocks and fuel. Cells use nutrients such as glucose and fatty acids, and mitochondria help convert that fuel into ATP—the energy currency cells use to do work. Meals, movement, sleep and other daily conditions all belong in this picture.

A simplified overview of normal physiology, not a sequence of proven effects from a supplement.

02 / UNDERSTAND THE MECHANISM

Meet AMPK.
One of the cell’s energy sensors.

AMPK helps coordinate metabolic processes in response to a cell’s energy status. Researchers study berberine partly because experimental findings connect it with AMPK-related signaling and glucose and lipid metabolism.

PRECLINICAL / MECHANISTIC RESEARCHWhat about mitochondria and ATP?Read the distinction +

Research in aging rats examined AMPK/SIRT1/PGC-1α signaling and mitochondrial outcomes after berberine treatment. Such experiments help identify mechanisms worth studying. They do not establish that Burn increases ATP, creates new mitochondria, or causes fat loss in people.

The next question matters most: what changes have actually been measured in people?

03 / LOOK AT HUMAN OUTCOMES

Mechanisms are interesting.
Human outcomes matter more.

Tap a card for the findings and the original source. These studies concern berberine—not clinical trials of Burn’s finished formula.

HUMAN META-ANALYSIS · Metabolic markers · 2025Glucose, lipids and waist circumferenceRead findings +

A review of randomized placebo-controlled trials found reductions in fasting glucose, triglycerides and waist circumference in the studied populations. LDL cholesterol, total cholesterol and BMI also improved; HDL and blood pressure did not show significant changes. The authors called for higher-quality trials.

HUMAN META-ANALYSIS · Body composition · 2026A modest average change in weightRead findings +

A meta-analysis of 23 articles reported an average weight difference of −0.88 kg (about 1.9 lb) versus control groups, alongside changes in BMI and waist circumference. Waist-to-hip ratio did not significantly change. Published online in November 2025, in the January 2026 journal issue. Results varied across study protocols.

HUMAN META-ANALYSIS · Glucose and lipids · 202450 studies. 4,150 participants.Read findings +

This review involved people with type 2 diabetes. It reported improvements in several glucose and lipid measures, with different findings for berberine alone and berberine added to medication. Common doses were 900–1,500 mg daily for one to three months. Those populations and doses differ from Burn’s intended daily use; this is not guidance to treat diabetes or change medication.

RANDOMIZED CLINICAL TRIAL · A different outcome · 2026What a larger individual trial foundRead findings +

In 337 adults with obesity and fatty liver disease without diabetes, six months of berberine did not significantly reduce visceral or liver fat compared with placebo. This helps explain why a promising mechanism is not a guarantee of a particular clinical outcome.

HOW TO READ THE EVIDENCE

A study result depends on its population, dose, duration and comparison group. Pooled averages describe research participants; they do not predict an individual result. Burn supplies 500 mg berberine HCl per daily serving. Follow the label rather than matching a research dose.

A note from Samir & Ozzie

We’re new. We’re building this in public.

CoreVital is a small, family-founded brand. We’re still earning your trust, one bottle, one conversation, and one honest experience at a time. Thank you for being part of the beginning.

We don’t have a long history of customer reviews yet. If you’ve been using Burn—including through our Founders program—we’d love to hear what your experience has been like. What’s working? What could be better? Your feedback helps us build a better CoreVital.

05 / FROM RESEARCH TO A DAILY FORMULA

Why we built Burn.

We wanted a clearly labeled botanical formula paired with practical guidance. Burn brings together 500 mg of berberine HCl and four companion botanicals per two-capsule serving.

Inside each daily serving

Tap for a short summary of each ingredient’s role as explained in the video. Amounts are per two capsules.

Berberine HCl500 mg

Energy signaling & glucose metabolism
In the video, Samir explains berberine’s role through AMPK, a cellular energy sensor involved in how the body uses fuel.

Milk thistle extract200 mg

Liver & antioxidant support
Samir describes milk thistle’s role as supporting the liver’s antioxidant defenses and its processing of the body’s metabolic workload.

Ceylon cinnamon bark extract200 mg

Insulin sensitivity & glucose transport
The video describes Ceylon cinnamon’s role in insulin sensitivity and glucose transport—how tissues receive glucose to use as fuel.

Black cumin seed extract150 mg

Antioxidant defense & inflammatory balance
Samir highlights black seed’s thymoquinone and its role in antioxidant defense, inflammatory balance, and protection against oxidative stress.

Ginger extract100 mg

Digestive movement & gut comfort
The video describes ginger’s role in digestive motility, gut comfort, and inflammatory balance—helping explain its place in the complete formula.

Ingredient mechanisms help explain the formulation rationale. They are separate from evidence that a particular finished blend delivers a measured clinical outcome.

What to expect from Burn

A plant-based dietary supplement for healthy metabolism support, with education around the habits that matter. It is not an injection, a crash diet or a promise to lose a set amount of weight in 30 days. It does not replace prescribed treatment.

Your 30 days of guidance begin after confirmed delivery. Your first bottle comes with clear refund terms, free standard U.S. shipping and no subscription.
