About the Brand

The manufacturer of this supplement is a company called Xtendlife, founded in 2000 and headquartered in Christchurch, New Zealand. They are a highly regarded producer of health supplements and skincare products developed by physicians.

In 2012 they built a state-of-the-art pharmaceutical-grade facility in New Zealand where they manufacture according to strict safety regulations.

How Does It Work?

Xtendlife CX8 is considered the best heart health supplement as it contains a potent blend of eight science-backed ingredients that work synergistically to address the primary issues causing health problems.

It boosts the synthesis of nitric oxide which improves circulation and vasodilation, as we said in our review of Striction BP. This can decrease blood pressure and prevent plaque from attaching to the arteries. In addition, this supplement can decrease bad cholesterol and triglyceride levels.

A review of the research published in Molecular Aspects of Medicine by Khalid M Naseem discussed the role of reduced availability of nitric oxide on cardiovascular disease development [2].

Xtendlife CX8 can also help decrease calcification of the soft tissue in your heart, which lowers your risk of heart attack and cardiovascular disease. In addition, the formula helps to replace damaged stem cells in the cardiovascular system.

A scientific article and review by Wei Liu, et al published in the Journal of Geriatric Cardiology explored the current knowledge of coronary artery calcification [3].

This supplement is very high in anti-inflammatory agents which decrease swelling in the heart and other organs, for improved blood flow.

In addition, Xtendlife CX8 has powerful free radical destroying antioxidants that can lessen oxidative stress. This promotes general repair and improved heart and immune system health, as we explained in our review of Herbaly.

A scientific article published in Antioxidants by Wenjun Wang and Peter M. Kang looked the role of antioxidants and decreasing oxidative stress in cardiovascular treatments [4].

Xtendlife CX8 Supplement Facts

Sea Buckthorn Fruit Extract

The berries of this plant are rich in antioxidants which lower oxidative stress in the heart and promote the growth of stem cells for damage repair. There’s evidence that it may lower blood pressure and cholesterol and reduce the risk of heart disease.

A research review in the International Journal of Food Science and Nutrition by Marietta Sayegh, Cristiana Miglio, and Sumantra Ray concluded that consumption of Sea Buckthorn berry may decrease cardiovascular risk factors [5].

Verdict: Sea Buckthorn offers potent heart health benefits and may reduce disease risk.


This is a pigment that exists in some fruits and vegetables and other plants. It increases the synthesis of nitric oxide in the body, improving circulation and vasodilation. It is full of antioxidants called flavonoids which can repair damage and protect the heart.

A research review by Hawa Nordin Siti, et al published in the Journal of Functional Foods concluded that consumption of rutin may play a role in cardiac remodeling including reducing the risk of hypertrophy and other issues [6].

Verdict: Rutin could offer powerful cardioprotective and repair properties.

Blackcurrant Fruit Extract

Packed with powerful antioxidants called polyphenols, this fruit supports immune system health and has particular benefits for the heart. Research shows it may reduce cholesterol, lower inflammation, and decrease the risk of developing heart disease.

A study on mice published in Nutrients by Hye-Yoom Kim, et al concluded that consumption of blackcurrant decreased inflammation and improved diabetic cardiac dysfunction [7].

Verdict: Blackcurrant offers potent benefits for heart health and immune system functioning.

All 8 ingredients have significant clinical data supporting their use for maintaining a healthy heart and arteries. Xtendlife manufactures all their own products in a state of the art facility in New Zealand.

This product has a truly excellent list of high quality ingredients in very respectable dosages but today I noticed something on the label that took me by complete surprise and made me come back to reduce my review from 5 stars to 2 stars. In the ingredients I noticed “maltodextrin”…
