Short answer: CardioC2 combines eight ingredients across four roles — nitric-oxide support, a traditional heart tonic, antioxidant protection, and heart-muscle energy support.
🧪 Beta-Cyclodextrin Crystal Support
Marketed by the brand as supporting the clearing of hardened cholesterol deposits. This specific "crystal-clearing" framing is a marketing narrative, not an established medical mechanism — treat it with appropriate skepticism.
🌱 Beet Root Extract (10:1) Circulation
Contains dietary nitrates associated with supporting blood vessel relaxation and improved oxygen delivery.
🩸 L-Citrulline Nitric Oxide
An amino acid the body converts into L-Arginine, supporting nitric oxide production and circulation.
🫀 Hawthorn Berry Heart Tonic
A traditionally used botanical associated with supporting healthy blood pressure and arterial function.
🩸 L-Arginine Nitric Oxide
A direct nitric oxide precursor, working alongside L-Citrulline to support blood vessel relaxation.
🍵 L-Theanine Vascular Calm
An amino acid associated with supporting relaxation, potentially relevant to stress-related vascular tension.
🧄 Black Garlic Extract Antioxidant
An aged garlic extract studied for antioxidant activity and supporting healthy nitric oxide levels.
⚡ Coenzyme Q10 Heart Energy
Supports cellular energy production, with a specific research focus on heart-muscle function.

Most of these ingredients have reasonable circulation and heart-support research behind them individually — the main point of caution is the "crystal-clearing" marketing narrative, which shouldn't be mistaken for established science. See our "does it work" breakdown for the full evidence picture.
