Supplement facts, per 2-capsule serving
IngredientAmountWhat it supports
Nitric Oxide & Circulation
L-Citrulline1,000 mgAmino acid the body converts into L-arginine and then nitric oxide, the molecule that signals blood vessels to relax and open.
L-Arginine500 mgA direct nitric oxide precursor that supports vasodilation and healthy circulation to the brain, hands and feet.
Beet Root Extract (10:1)150 mgA concentrated source of dietary nitrates traditionally used to support blood flow and exercise stamina.
Pomegranate Extract (40% ellagic acid)100 mgPolyphenol-rich fruit extract studied for its support of vascular function and oxidative balance.
Arterial Clearing & Cholesterol Support
Beta-Cyclodextrin250 mgA ring-shaped sugar molecule researched at the University of Konstanz for its ability to bind cholesterol and support the body's natural clearing of arterial buildup.
Aged Black Garlic Extract200 mgFermented garlic rich in S-allyl cysteine, valued for supporting vessel elasticity and already-healthy blood pressure.
Red Yeast Rice200 mgA traditional fermented rice used to support healthy cholesterol levels already within a normal range.
Mango Leaf Extract (mangiferin)100 mgSource of mangiferin, a polyphenol studied for metabolic and vascular support.
Heart Strength & Cellular Energy
Hawthorn Berry Extract (1.8% vitexin)300 mgA centuries-old heart tonic that supports the heart muscle, steady rhythm and circulation.
L-Theanine150 mgAn amino acid from tea leaves that supports calm focus and mental clarity without sedation.
Coenzyme Q10 (ubiquinone)100 mgA cellular spark plug that fuels energy production in heart and muscle cells and tends to decline with age.
Inositol100 mgA cell-signaling nutrient that supports healthy metabolism and a balanced mood.
Vitamin K2 (MK-7)90 mcgHelps direct calcium toward bone and away from soft tissue, supporting arterial flexibility.
BioPerine Black Pepper Extract5 mgStandardized piperine that improves absorption of the nutrients alongside it.

Sourcing and quality

Where an ingredient comes from matters as much as how much of it you get. The beet root and pomegranate are standardized extracts rather than cheap powders. The black garlic is aged, not raw, to concentrate the S-allyl cysteine that raw garlic lacks. The hawthorn is standardized to vitexin so each batch delivers a consistent amount of the active. We finish with a small dose of BioPerine black pepper extract, which research shows improves absorption of the nutrients alongside it.

Every batch of CardioC2 is produced in an FDA-registered, cGMP-certified facility in the United States and screened by Halverson Bioanalytics, LLC for identity, potency, heavy metals and microbials before it is released. You can review the current batch record on the verification page and read more about our process on the lab testing page.

Allergens and suitability

CardioC2 is non-GMO, gluten-free and made without artificial colors. It is produced in a facility that also handles common allergens, so if you have a severe allergy, review the label and check with us first. The formula is intended for healthy adults. It is not for children, and not for anyone who is pregnant or nursing.

How the three pillars work together

The reason the formula is grouped into three pillars is that healthy circulation depends on three things happening at once, and addressing only one creates a bottleneck. Picture a garden hose. The opening pillar, built on L-citrulline and L-arginine, is the pressure that widens the hose so more can flow through. The clearing pillar, anchored by beta-cyclodextrin and aged black garlic, is what keeps the inside of the hose free of the gunk that narrows it. The fueling pillar, hawthorn and CoQ10, is the pump itself, the heart muscle that has to keep pushing. Strengthen the pump but leave the hose clogged and little changes. Clear the hose but lose the pressure and the same is true. CardioC2 is dosed so the three reinforce each other rather than compete.

It is also why the doses are not interchangeable with a stack of separate pills. The amino acids are set high because the body converts only a fraction into nitric oxide. The botanical extracts are standardized so the active compound, vitexin in hawthorn or S-allyl cysteine in black garlic, lands in a consistent range. A pinch of BioPerine ties it together by helping the fat-soluble nutrients absorb.

Who CardioC2 is for, and who should wait

CardioC2 is formulated for healthy adults, and it tends to resonate most with people over 45 who notice the early signs of declining circulation: cold hands and feet, an afternoon energy dip, brain fog, or legs that tire sooner than they used to. It is a daily foundation rather than a stimulant, so there is no jitter and no crash.

It is not for everyone, and we would rather you know that up front. It is not intended for children, for anyone who is pregnant or nursing, or as a replacement for medication your doctor has prescribed. If you are scheduled for surgery, several ingredients can affect bleeding and clotting, so pause use and tell your surgeon.

A note on medication

This is important. Garlic, hawthorn, CoQ10 and red yeast rice can interact with blood thinners, blood pressure medication, statins and certain cardiac drugs. If you take any of these, do not start CardioC2 until your physician has reviewed the label. The clearing pillar is designed to work with your body, not against your prescriptions, but only your doctor can confirm it is right for you.
