Hello, I’m Dr. Kevin Passero. Over the past 20 years of caring for patients in my Washington, DC clinics, I’ve explored countless natural approaches to heart health, and nothing has impressed me as much as this one.
It’s a little-known citrus fruit from Southern Italy called Citrus Bergamot—rich in polyphenols and flavonoids that promote healthy cholesterol levels, blood sugar balance, and overall cardiovascular function.

Importantly, unlike the commonly recommended approaches that may disrupt brain cholesterol levels, bergamot works peripherally—lowering bad cholesterol in the body without interfering with the cholesterol critical for cognitive function.

Why I Trust Citrus Bergamot with My Patients' Heart Health
Why I Trust Citrus Bergamot with My Patients' Heart Health
Before I recommend any nutrient to my patients, I look for consistent clinical evidence—not just one promising study.
That’s why I was encouraged when researchers from a leading university conducted a thorough review of more than 200 studies on Citrus Bergamot. They identified five gold-standard clinical trials that met the highest standards of scientific rigor—and the results were outstanding.
In every study, participants experienced:
• Significant reductions in LDL cholesterol and triglycerides
• Noticeable increases in HDL (the “good” cholesterol)
As both a scientist and a physician, I found the consistency and strength of these findings compelling.
And what became clear as I reviewed the data was this:
One specific form of Citrus Bergamot consistently delivered the best results—better than any generic extract on the market.
The most important factor for me to see is clinical confirmation of results that carry forward from one study to the next. Often times the trendy “solutions” are associated with just one hyped up study which is not enough for me to make clinical decisions for my patients.

The Right Form and the Right Dose
of Citrus Bergamot for Best Results
The Right Form and the Right Dose of Citrus Bergamot for Best Results
Not all citrus bergamot is created equal.
The extract I recommend is a patented form called Bergamonte®, which has been evaluated in 14 published human clinical trials—far more than most natural ingredients ever receive.
These studies consistently show Bergamonte® provides superior support for healthy cholesterol and triglyceride levels—outperforming generic bergamot and other natural options.
In one standout trial, participants who took 1,000 mg daily for 30 days saw*:
Total cholesterol: ↓ 29%
LDL (“bad”) cholesterol: ↓ 36%
HDL (“good”) cholesterol: ↑ 40%
Triglycerides: ↓ 39%
Blood sugar: ↓ 22%
These are the kind of results that make a real difference—and why I use a 1000 mg daily dose of Bergamonte® for my patients’ heart health.

How Bergamonte® Works to Support Healthy Cholesterol
Patients often ask me: “How can something natural work this well?”
The answer lies in the unique polyphenols found in citrus bergamot—especially in the clinically studied Bergamonte® extract. These compounds support heart and metabolic health through multiple natural mechanisms:
• Reduces LDL ("bad cholesterol") – helping prevent plaque buildup in the arteries
• Inhibits HMG-CoA reductase - a key enzyme in cholesterol production
• Activates Cholesterol 7α-hydroxylase – converting cholesterol into bile for removal
• Reduces LDL ("bad cholesterol") – helping prevent plaque buildup in the arteries
• Inhibits HMG-CoA reductase - a key enzyme in cholesterol production
• Activates Cholesterol 7α-hydroxylase – converting cholesterol into bile for removal
• Stimulates AMPK – your body’s “metabolic master switch” that regulates blood sugar and lipids
Unlike approaches that may interfere with brain cholesterol levels, bergamot works peripherally—helping to lower bad cholesterol in the body without disrupting the cholesterol your brain relies on for memory, focus, and mood.
Not All Citrus Bergamot Supplements Are Created Equal
Here is a quick summary of why I recommend a 1000 mg daily dose of patented Bergamonte® citrus bergamot instead of the more widely available generic citrus bergamot:
| Feature | Bergamonte® (Patented) | Generic Citrus Bergamot |
|---|---|---|
| Source | Patented extract from Italy | Variable, often undefined origin |
| Standardization | Highly standardized for polyphenolic content (e.g., ≥38%) | Inconsistent standardization (may lack active compounds) |
| Clinical Research | Backed by multiple human clinical trials | Little to no human research |
| Cholesterol Support | Clinically shown to lower LDL, raise HDL, and reduce triglycerides | May offer some benefit, but results are anecdotal |
| Blood Sugar & Metabolic Health | Shown to improve insulin sensitivity and reduce glucose | Not clinically validated |
| Safety & Tolerability | Demonstrated safe in trials; no side effects | Unknown safety profile |
| Absorption / Bioavailability | Optimized for absorption | Often poorly absorbed |
| Manufacturing Standards | Produced in GMP-certified, pharma-grade facilities | Varies by supplier |
| Consistency | Every batch tested for potency and purity | Quality may vary by batch |
| Cost | Higher, but justified by quality and clinical validation | Lower, but lacks assurance and research |

Your 5-Step Citrus Bergamot Buyer’s Guide
To get the full benefits of citrus bergamot, it’s critical to choose the right formulation—one that matches what’s been proven in clinical research.
As I tell my patients, when choosing a citrus bergamot supplement, the answer to ALL five of these questions must be “YES”:
1. Is it made with patented Bergamonte® extract?
🔲 Yes 🔲 No
Only Bergamonte® is standardized to deliver a clinical-strength dose of polyphenols (>38%) and is backed by 14 published human trials. Generic forms simply don’t compare.
2. Does it deliver the full 1,000 mg daily dose?
🔲 Yes 🔲 No
This is the dose used in clinical studies showing LDL reductions of up to 36% and HDL increases of 40%. Most products only offer 500 mg — shown to be 50% less effective in lowering LDL and 82% less effective in raising HDL cholesterol.
3. Does it include vitamin C?
🔲 Yes 🔲 No
Vitamin C enhances the activity of Bergamonte® and offers added antioxidant support. It’s a simple but often-overlooked addition that makes a meaningful difference.
4. Does it include olive leaf extract?
🔲 Yes 🔲 No
Rich in oleuropein, olive leaf supports healthy inflammation response and lipid metabolism—two essential parts of cardiovascular health.
5. Is it made in the USA and independently tested?
🔲 Yes 🔲 No
Quality matters. Look for supplements manufactured in FDA-inspected, cGMP-certified facilities with 3rd-party testing for purity and potency.
✔ When the answer to all five questions is YES—you know you’re getting a bergamot supplement that truly delivers.

A Smarter Way to Support Cholesterol—
Inspired by My Patients
A Smarter Way to Support Cholesterol— Inspired by My Patients
The protocol I developed for my patients—using citrus bergamot, vitamin C, and olive leaf—produced great results. But it wasn’t easy to follow.
Some supplements didn’t use Bergamonte®, or used just 500 mg—far below the clinically superior 1,000 mg dose. And buying separate vitamin C and olive leaf supplements added cost and complexity.
That’s why I knew we needed a better solution.
As Chief Science Officer at Durable®, I worked with my friend and natural health advocate Josh Corn to create a product that simplifies this powerful protocol—without cutting corners.
