How to Lower LDL and Raise HDL Naturally—Backed by Real Clinical Results
Hello, I’m Dr. Kevin Passero. In my 20+ years of reviewing cholesterol panels with patients, I’ve seen the same challenge again and again: too much LDL (“bad”) cholesterol and not enough HDL (“good”) cholesterol. Together, this imbalance significantly impacts long-term heart and vascular health.
When it comes to cholesterol, focusing on a single number rarely tells the full story. What really matters is the balance between LDL, HDL, and triglycerides—and the ratios they create. Elevated LDL drives plaque buildup, low HDL limits cholesterol clearance, and high triglycerides raise risk even further.
Research shows that the triglyceride-to-HDL ratio is a key marker of cardiovascular and metabolic health. Yet many factors—diet high in saturated or trans fats, lack of exercise, excess weight, smoking, genetics, and even age—can throw this balance off.
In my clinic, I often see patients searching for a safe, effective alternative to conventional methods which often come with harsh side effects. Many have already tried cholesterol supplements, only to be let down by weak, underdosed formulas that don’t deliver results. When they ask me how to lower LDL, raise HDL, and improve triglycerides naturally, my answer is clear: citrus bergamot.
Of all the nutrients I’ve studied, citrus bergamot, a little-known polyphenol-rich citrus fruit, is among the most researched and clinically validated—shown to support healthy cholesterol, triglycerides, and overall metabolic balance.
That’s why, as Chief Science Officer of Durable®, the company I co-founded with my good friend and natural health advocate, Josh Corn, I developed Durable HEART®. It delivers Bergamonte®—the patented citrus bergamot extract grown exclusively in Calabria, Italy. It's the only citrus bergamot with clinically proven, standardized levels of five active polyphenols and validated in 14 published human trials.
Unlike generic bergamot, it’s the only form proven to deliver meaningful results:

Why Citrus Bergamonte® Works for Natural Cholesterol Support
Why Bergamonte® Works—and Why It Makes Durable HEART® the Best Cholesterol Lowering Supplement
Citrus bergamot is a polyphenol-rich fruit grown in Calabria, Italy. But not all extracts are equal. Only Bergamonte® is grown exclusively in this region and standardized for clinical potency.
Its bioactive compounds—especially brutieridin and melitidin—work on multiple cholesterol-regulating pathways, without the common side effects often seen with conventional approaches.
Bergamonte® supports cardiovascular and metabolic health through these mechanisms:
Unlike conventional approaches, Bergamonte® works peripherally—lowering harmful cholesterol in the body while preserving healthy brain cholesterol important for memory and mood.
Why 9 Out of 10 Citrus Bergamot Supplements Fail Clinical Standards
Why 9 Out of 10 Citrus Bergamot Supplements Fail Clinical Standards
Here’s the problem: the supplement market is flooded with low-quality, ineffective formulas. Most bergamot products are made with:
- Non-standardized bergamot extracts with no clinical backing
- Ineffective dosages far below the 1,000 mg proven level
- No absorption support such as vitamin C to enhance bergamot’s effectiveness
- No complementary compounds like olive leaf extract for cardiovascular synergy
- No third-party testing to ensure purity and potency
Without the right extract, dosage, and absorption support, you could take bergamot for months without meaningful improvements. That’s why Durable HEART® uses Bergamonte®—the patented, clinically studied citrus bergamot extract—delivered at the extra-strength1,000 mg clinical dosage and recognized as the most researched form of citrus bergamot.
Why Olive Leaf Extract Makes Durable HEART® Better
While Bergamonte® delivers unmatched performance in terms of balancing cholesterol and lowering triglycerides, Durable HEART® takes it a step further with 100 mg of pure, standardized olive leaf extract, sourced from freshly picked Spanish olive leaves and processed immediately after harvest to preserve maximum potency.
Olive leaf extract is rich in oleuropein, a powerful polyphenol that:
- Supports healthy lipid metabolism to help maintain optimal cholesterol balance*
- Promotes arterial health by protecting vessel walls from oxidative stress*
- Helps regulate inflammation for better cardiovascular resilience*
Most bergamot supplements skip this crital companion ingredient. We include it because olive leaf’s benefits perfectly complement Bergamonte®—providing broader heart and arterial support for a more complete cardiovascular solution.
What Makes Durable HEART® the Best Choice for Cholesterol & Triglyceride Support
What Makes Durable HEART® the Best Choice for Cholesterol & Triglyceride Support
In my clinic, I’ve seen too many patients frustrated by cholesterol supplements that simply don’t deliver. They’re often underdosed, unstandardized, or missing the key companion nutrients that make all the difference. That’s why I created Durable HEART®—a clinical-grade cholesterol supplement built on the same protocol I trust with my own patients.
1. Bergamonte® Citrus Bergamot — The Gold-Standard, Full-Spectrum Extract
Durable HEART® delivers a extra-strength 1,000 mg clinical dosage of Bergamonte®—the only patented extract grown exclusively in Calabria, Italy and standardized to >38% polyphenols.
Backed by over 200 research papers and validated in 14 published human trials, Bergamonte® is also the only bergamot extract proven free of compounds known to interfere with other medications. That makes it the most clinically validated—and safest—form available, and the only one I trust in my clinic.
2. Full Clinical Dosage — Proven in Human Trials
Most supplements that feature Bergamonte® provide only 500 mg per serving. Durable HEART® doubles that amount, delivering the exact 1,000 mg daily dosage used in human trials—shown to lower LDL, raise HDL, reduce triglycerides, and support healthy blood sugar in as little as 30 days. Research shows this level to be up to 80% more effective than the 500 mg dose.*
3. Vitamin C for Enhanced Bergamot Benefits
Most formulas leave out this critical cofactor. Durable HEART® includes 50 mg of premium non-GMO vitamin C to help your body fully utilize Bergamonte® while providing additional antioxidant support.* See the study →
4. Olive Leaf Extract for Artery & Inflammation Support
To further strengthen the formula, I included 100 mg of pure olive leaf extract, sourced from freshly picked Spanish olive leaves and processed immediately after harvest to preserve potency. Rich in oleuropein, this powerful polyphenol supports healthy lipid metabolism, arterial flexibility, and balanced inflammation—making it the perfect complement to Bergamonte®.* See the study →
5. Doctor-Formulated for Quality and Safety — Down to the Bottle
With over 20 years of clinical experience, I designed Durable HEART® to meet the highest standards of safety, purity, and effectiveness:
- Clinical-grade ingredients at the dosages proven in human trials
- Clean, non-GMO formula—no fillers, dyes, or unnecessary additives
- Made in the USA in an FDA-approved, cGMP-certified facility
- Third-party tested for purity, potency, and safety
- Packaged in amber glass bottles to protect against UV light and plastic leaching
- Backed by our 1-Year “Better Labs or Your Money Back” Guarantee
