US Clinicals® StrongHeart™


Based on the science behind a Nobel Prize winning medical breakthrough, StrongHeart™ Cardio Support Formula is 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.

Nobel Prize Research: Nitric Oxide
Wonders of nitric oxide
  • Supports healthy blood circulation
  • Supports healthy heart function
  • Maintains healthy blood pressure and cholesterol levels

L-Arginine is an amino acid present in human proteins. 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 facilitate wound healing. 

L-Citrulline is an amino acid that is 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. 

L-Taurine is 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 contains 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 in anti-aging. Resveratrol helps reduce LDL (bad cholesterol) and makes it harder for platelets to stick together. This prevents blood clots from forming and leading to heart diseases.  

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