One scoop. 60–90 minutes pre-workout. Or morning ritual for daily vascular health.

The clinical dose is linked to a 14% increase in flow-mediated dilation (Schroeter PNAS 2006). Built to the COSMOS dose. Same SKU as Heart Health and Menopause, framed for movement.

What's inside
  • 1,200 mg cacao flavanols — standardized to 600 mg (−)-epicatechin per scoop
  • Cacao Powder — cold-pressed, low-heat processed
  • Cacao Butter — cold-pressed, flavanols intact
  • Vanilla Bean — whole bean, sun-cured
  • Lucuma Powder — low-glycemic, no added sugar
  • Mineral Pink Salt — unrefined

Other ingredients: none. No fillers. No proprietary blends. No preservatives.

How to use it

One scoop. Eight ounces of warm oat milk or hot water.

Best timing for performance: 60–90 minutes pre-workout. Plasma nitric-oxide markers peak in that window. For daily vascular health, morning with breakfast works equally well — outcomes accumulate with consistency.

Naturally caffeinated (~12 mg per serving, about a quarter of a cup of coffee).

The published record
  • Schroeter et al. PNAS 2006 — 14% increase in flow-mediated dilation (vasodilation) from a 900-mg cacao flavanol dose
  • Heiss et al. Circulation 2010 — endothelial NO-synthase upregulation, sustained vasodilation
  • Sansone et al. Br J Nutr 2015 — cacao flavanols improve vascular function in healthy adults
  • COSMOS Trial · 21,442 adults · Am J Clin Nutr 2022 — 27% lower cardiovascular death at 1,200 mg flavanol dose

Why athletes are paying attention

Vasodilation under load is a trainable variable.

The athletes who switched to cacao flavanols didn't do it for marketing. They did it because the dose hit a measurable ceiling on flow-mediated dilation that their pre-workouts couldn't.

01
The Problem

Most pre-workouts boost output, not vasculature.

Caffeine, citrulline, beta-alanine: each pushes a different lever, but none directly upregulate endothelial nitric oxide synthase (eNOS). That's why pre-workouts plateau on circulation while still delivering acute energy. The cap is vascular, not muscular.

Bryan & Lefer · Heart Fail Rev · 2009
02
The Mechanism

Epicatechin upregulates eNOS directly.

Schroeter isolated (–)-epicatechin as the cocoa monomer that raises eNOS activity and produces measurable 14% increase in flow-mediated dilation in healthy adults. CCV-3® delivers 600 mg of standardized epicatechin per scoop, taken 60 to 90 minutes before training.

Schroeter et al · PNAS · 2006 · 14% FMD increase
03
The Outcome

Built for movement. The COSMOS dose, every scoop.

CCV-3® delivers 2.2x more flavanols and polyphenols, in one daily ritual. The mechanism and the dose line up with what the trials measured. Same SKU as the Heart and Menopause rituals. Framed for movement.

The Standard

Built to one spec. Every batch.

A single source. A single dose. A single way to make it.

✓
Cold-press extraction
No solvents · Non-alkalized · Low heat
Heat-sensitive flavanols are preserved when cacao is processed gently. Most commodity cacao loses 90%+ of its flavanols to industrial alkali Dutching.
✓
CCV-3® dose, standardized
1,200mg flavanols · 600mg epicatechin
Standardized to the CCV-3® protocol every batch. Not "may contain" — measured to spec. The dose your cardiovascular system actually responds to.

Harmony morning ritual

When Results Appear

The timeline.

When peer-reviewed trials report results, this is when they show up. Real research, real windows.

Day 14–21
Subjective lift

Most ritual users report focus, steady energy, and feeling more like themselves by week three. Subjective signals — but consistent across our community.

Day 30–60
Measurable change

Flow-mediated dilation — the gold-standard measure of endothelial function — begins shifting at this window in controlled trials.

Schroeter et al · PNAS · 2006

Year 1+
Long-term research

In COSMOS, daily cocoa extract supplementation showed promising cardiovascular findings over 3.6 years across 21,442 adults. HarmonyMD is not the COSMOS product.

Frequently asked questions.

01 What is Harmony MD Cacao Cellular Complex?
A cacao powder developed with physician input, delivering 1,200mg of flavanols per scoop — the flavanol dose used in the COSMOS trial published in the American Journal of Clinical Nutrition.
02 How long until I notice results?
Most users notice changes within 7–14 days. The COSMOS trial measured outcomes across 3.6 years of daily use, so the cumulative effect builds with consistent use.
03 Is it allergen-free?
Yes. The formula is vegan, non-GMO, gluten-free, soy-free, and contains no artificial sweeteners, fillers, or preservatives. Five ingredients only.
04 What is CCV-3® and why does it matter?
CCV-3® is our internal quality standard ensuring each batch delivers exactly 1,200mg of cacao flavanols with 600mg standardized epicatechin — built around the same flavanol and epicatechin mechanism studied in COSMOS, at 2.4× the trial flavanol dose. Without standardization, you can't reproduce the mechanism reliably.
05 How is each batch standardized?
Every batch is standardized to the CCV-3® protocol — 1,200 mg of cacao flavanols and 600 mg of (−)-epicatechin per scoop. Verified to spec before it ships.
06 How do I manage my subscription?
Log in to your account portal to pause, skip, change frequency, or cancel at any time. No minimums. No penalties.
07 How long does one jar last?
Each jar contains 25 servings at the 10g daily scoop — one full month of the morning ritual at the COSMOS dose. Subscribers receive a fresh jar every 30 days so their supply never lapses.
08 Can I take Harmony with other medications?
Always consult your physician before adding any supplement to your regimen, particularly if you take blood thinners, statins, or blood pressure medication. The COSMOS trial included participants on various medications; your clinician knows your case.
09 Does Harmony have any caffeine?
Each serving contains approximately 12mg of naturally occurring caffeine — less than a quarter of a standard cup of coffee. This is naturally present in cacao and cannot be removed without destroying the flavanols.
10 How long does one bag last?
One jar contains approximately 25 servings when used as directed.
11 Is Harmony sweetened?
No. Harmony contains no added sugar and no artificial sweeteners.
12 Why have more than 200,000 people tried Harmony?
Many customers are looking for a simple daily ritual built around concentrated cocoa flavanols rather than highly processed chocolate products.
13 What happened to the cacao in modern chocolate?
Many chocolate products are formulated for taste first. During processing, the naturally occurring cocoa compounds researchers study can be significantly reduced.
14 Why are flavanols missing from most chocolate?
Flavanols are sensitive compounds. Traditional processing methods used to create sweeter, smoother chocolate often reduce their concentration.
15 If chocolate comes from cacao, why doesn’t chocolate provide the same benefits?
Chocolate and high flavanol cacao are not the same thing. The amount of flavanols can vary dramatically depending on how the cacao is processed.
