Studied mechanism
Six pillars of cardiovascular vitality.
Each pillar is a measured outcome from peer-reviewed cacao flavanol research.
Healthy Blood Flow
Cacao flavanols promote vasodilation by supporting nitric oxide synthesis — the foundational pathway endothelial cells use to regulate vascular tone.
Heiss et al · J Cardiovasc Pharmacol · 2010Cognitive Sharpness
Improved cerebral blood flow correlates with measurable gains in working memory and processing speed across multiple controlled trials.
Brickman et al · Nat Neurosci · 2014Endothelial Function
Daily flavanol intake at studied doses improves flow-mediated dilation — the gold-standard measure of vascular health.
Schroeter et al · PNAS · 2006Sustained Energy
Naturally occurring 12mg of caffeine and theobromine deliver clean morning lift — no jitters, no afternoon crash, no synthetic stimulants.
Antioxidant Defense
Cacao flavanols rank among the highest natural antioxidants by ORAC score, neutralizing oxidative stress in vascular tissue.
Vinson et al · J Agric Food Chem · 200627% Lower CV Death
The COSMOS trial measured a 27% reduction in cardiovascular death over 3.6 years — the strongest cacao nutrition outcome ever published.

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 studied dose from 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 verified?
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 30 servings at the studied 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.
