Superior Quality
Heart Health Support
High levels of calcium ions being deposited into tissues can affect a wide range of body tissues, including blood vessels, cartilage, and the heart's valves, making them harder and less flexible. Calcification in the arteries may increase the risk of heart disease, which is referred to as “the silent killer".
CX8 is formulated with highly researched ingredients backed by data to support calcium metabolism, circulation, and inflammation management. The eight potent ingredients formula offers you one of the most effective heart-health products available today.
Circulation and Calcification
Arteries play a fundamental role in maintaining proper blood circulation throughout the body, it is crucial to keep arteries in good condition to maintain good cardiovascular health. CX8 contains a proprietary blend of protease enzymes (Nattozimes®) and vitamin K2 in MK-7 form, these well-researched ingredients present great evidence to support calcium metabolism and may prevent the buildup of calcium in the arteries.
You may find there are several types of vitamin K2, and MK-7 (menaquinone-7) is often considered the best form of vitamin K2 for heart health, because of its superior bioavailability, effectiveness and ability to support arterial calcium regulation.
The MenaQ7® MK-7 vitamin K2 used in CX8 has been conducted in an overwhelming number of clinical trials, it’s micro-encapsulated which guarantees stability.
Inflammation and Cellular Support
Inflammation plays a complex role in heart and artery health. Excessive inflammation can damage the thin layer of cells in the inner blood vessel walls, affecting the ability to regulate blood vessel tone and blood flow. Chronic inflammation is also often associated with metabolic syndrome, contributing to high blood pressure and unbalanced cholesterol.
CX8 is formulated with a complex blend of active ingredients with potent anti-inflammatory properties to protect and support good heart health. It contains DeltaGold® tocotrienol complex, the most potent anti-inflammatory vitamin E, to help prevent lipid oxidation in CVD, and support cardiovascular and metabolic health. Combined with additional antioxidants sea buckthorn fruit extract (CardiOmegia™, CyanthOx™30), rutin and New Zealand blackcurrant extract, this unique heart health supplement is great for supporting healthy inflammation and good cardiovascular health.
Each serving of CX8 also offers 1000IU of vitamin D3, to help maintain healthy blood flow and protect the heart and blood vessels.
We believe you deserve to know exactly what you’re putting in your body, no confusing labels, no hidden fillers, no compromises.
