The Problem

"I Already Cut Back on Salt & Started Walking.
Why Would This Work Different?"

Most heart and liver "solutions," even the ones your doctor recommends, solve the wrong problem. They're built to move a number on a lab report — not to support the actual mechanism happening in your blood vessels every single day.

A good number on paper isn't the same as knowing what's actually happening inside you — and most solutions only address one, not the other.

Common things people try for heart and liver health
NUMBER ONLY

Diet Changes

Can lower your cholesterol on paper, but does nothing for the worry that it's already too late underneath it.

TEMPORARY ONLY

Generic Fish Oil

Sounds like the right idea, but most formulas aren't dosed to actually reach the mechanism you're worried about.

HIGH EFFORT

Repeat Lab Monitoring

Can genuinely help track progress, but means months of waiting rooms just to find out if you're still "okay."

HEAVY-HANDED

Prescription Statins

Can move the number, but comes with side-effect anxiety, cost, and the sinking feeling that this is now forever.

SURFACE FIX

Fitness Trackers

Shows you your heart rate in real time, but tells you nothing about what's actually happening in your vessels.

The Solution

Premium Cocoa Nutrient Complex

Premium Cocoa Nutrient Complex was created specifically for people who've already done the "right things" — the diet changes, the walking, the lab checkups — and still feel like something could be quietly going wrong underneath it all. Its daily cocoa flavanol formula is designed to support the actual vascular mechanism behind your numbers, not just the number itself — without a new prescription, a new diet, or another appointment to remember.

LiverHeart Complex Cocoa Flavanol Supplement
LiverHeart Complex Cocoa Flavanol Supplement

Targets the Mechanism, Not Just the Number

Built around epicatechin, the same compound studied for supporting healthy nitric oxide production and vascular function — the part your lab report doesn't show.

Daily Support, Not a One-Time Fix

One serving of powder a day, built for consistent long-term use — the same way the research behind cocoa flavanols was studied, not a quick before-and-after gimmick.

No Prescription, No New Side Effects

A drug-free daily supplement for everyday heart and liver support — nothing to titrate, nothing new to explain at your next appointment.

Backed By Real, Published Research

Grounded in decades of Harvard-studied cocoa flavanol research — not inflated "stem cell" claims you can't verify.

Backed by Studies that Show:

Improved Memory in 8-12 Weeks

+24% Spatial Memory

+14% Long-Term Memory

ERONA Cocoa Flavanols

Inside ERONA

What Are Cocoa Flavanols & Flavonoids?

High-flavanol cocoa naturally contains plant compounds studied for their role in supporting healthy circulation, nitric oxide production, and overall cardiovascular wellness.*

01

What Are Flavanols?

Flavanols are naturally occurring plant compounds found in cocoa. They have been studied for their ability to support healthy endothelial function, nitric oxide production, and blood flow.*

ERONA uses high-flavanol cocoa designed to preserve more of these valuable compounds than heavily processed conventional cocoa.

02

What Are Flavonoids?

Flavonoids are a broader family of phytonutrients naturally found in fruits, vegetables, tea, and cocoa. Cocoa flavanols are one specific group within that larger flavonoid family.

These plant compounds are valued for their antioxidant activity and are widely researched in connection with cardiovascular and cellular health.*

KEY FLAVANOL

The Power of (-)-Epicatechin

(-)-Epicatechin is one of the key naturally occurring flavanols found in cocoa and one of the compounds most closely studied for its relationship with nitric oxide and vascular function.*

Latoya Treutel

I was searching for a high‑quality flavanol cocoa supplement for heart and circulation support, and this one really stands out. Each serving provides 1200mg flavanols & flavonoids, including 600mg (-)-epicatechin. It is sugar‑free, just 27 calories per serving, so it fits well into my healthy diet. I stir one serving into warm oat milk each day. The cocoa taste is deep and pleasant, not overly bitter. It supports cardio performance and overall heart health. The jar contains 30 servings, which lasts a full month. After consistent use, i feel my blood circulation is better, and i have more endurance during my workouts. I appreciate that it’s a natural dietary supplement without added sugar. Highly recommend for anyone wanting to support heart health and circulation with cocoa flavanols.

This black forest powder is a great find. it contains 10x more flavanols than regular cocoa and 600mg of epicatechin. it is a very helpful supplement for heart health and energy, especially since it has zero sugar and only 30 calories.
