Based on the science from a Nobel Prize winning medical breakthrough, StrongHeart™ Cardio Support Formula that has been scientifically designed to promote a healthy cardiovascular system. It combines L-Arginine with L-Citrulline and other vital nutrients to boost the body's production of Nitric Oxide (NO) - the miracle molecule that keeps your blood moving freely throughout the body. 

With StrongHeart™, you can now give your heart the boost and protection it needs to feel good all day long!
Dr. Louis J.Ignarro – Nobel Prize in Medicine: “We can reverse cardiovascular damage with NITRIC OXIDE.”
  • Relax blood vessels
  • Improve blood circulation
  • Relieve stress on the heart
  • Maintain healthy blood pressure and cholesterol level
  • Support cardiovascular health


An amino acid present in human proteins that is obtained naturally from the diet. It is the body's main source of nutrients for producing nitric oxide, which helps improve blood flow in the arteries and effectively prevent coronary heart diseases. It is also known to improve immune function and facilitates wound healing. 


An amino acid that is found to be critical in the production of nitric oxide. It acts as a catalyst when combined with L-Arginine and extends the body's production of nitric oxide up to 24 hours long. It also helps promote healthy vasodilation and blood circulation which contributes to a healthy blood pressure. 


An amino acid that helps to move key nutrients, such as potassium, magnesium and calcium, in and out of our heart's cells to improve its functioning. It also increases the secretion of nitric oxide, improves blood flow and facilitates the delivery of oxygen to the muscles. 

Pine Bark 

Pine Bark extract is naturally derived from the inner bark of certain pine trees. It has potent antioxidants and compounds that help dilate blood vessels. It also provides strong vascular and capillary supports that are essential for nutrient delivery.


Resveratrol is a unique polyphenol that exists in red wine and some plants. It has been shown to support healthy cardiovascular function and anti-aging. Resveratrol helps reduce LDL (bad cholesterol), makes it more difficult for platelets to stick together and prevents blood clots from forming which can lead to heart diseases. 

Cinnamon Bark 

Cinnamon Bark has been used traditionally as a culinary spice and to support proper digestion. Numerous studies show that cinnamon also helps regulate blood sugar and reduce LDL cholesterol levels.
