Perfusia-SR, sustained-release L-arginine, promotes the production of nitric oxide in the arteries. The vascular benefits include improved blood flow and maintenance of normal blood pressure.

Clinically Studied

A recent study demonstrated improvements in blood flow after Perfusia-SR supplementation in individuals who had less than optimum heart health. In another study, Perfusia-SR was given to 29 healthy volunteers for one week and significant support for a healthy cardiovascular system was observed. Studies on Perfusia-SR show increased blood flow to the heart muscle and the extremities, maintenance of already normal blood pressure, and improved vascular elasticity.

Unique Formula

There is significant research on the cardiovascular benefits of L-arginine – the primary ingredient in Perfusia-SR – for supporting vascular health and blood flow. One of L-arginine's most important roles is a biological precursor of nitric oxide.

Greater Absorption

Perfusia-SR is provided in a sustained-release formula to maintain an optimal level of L-arginine over 24 hours with suggested twice-daily use.

Thorne Bestseller

Thorne has been trusted by health-care practitioners, U.S. National Teams, and families around the world for more than 30 years. Thorne Bestsellers are a testament to Thorne's mission to provide high-quality supplements that are tested for quality, safety, and efficacy.

When our tissues need additional blood supply, like during exercise, or when we’re stressed, our blood vessels need to dilate efficiently. If blood vessels are not as elastic as they should be, then our health can suffer. The production of nitric oxide is very important to blood vessel health. When an adequate amount of nitric oxide is produced in our blood vessels, the vessels are more elastic, normal blood pressure can be maintained, sexual arousal occurs normally, and cardiovascular health is promoted. Thorne supplements enhance the body’s production of nitric oxide, thus promoting healthy blood vessels.

Sourcing Exceptional Ingredients

We develop better standards for higher quality ingredients. Thorne cares deeply about where our ingredients come from. We partner only with suppliers whose practices emphasize quality, science, and responsibility. Better ingredients means better potency, absorption, and digestibility - and ultimately better health.

Manufacturing the Right Way

We manufacture our own products to ensure full supply chain transparency. For more than 30 years, we have invested in clean manufacturing practices. We refuse to use ingredients that can inhibit absorption. We perform our final production in the United States. Our Charleston, SC facility is third-party certified.

Four Rounds of Testing

We run four rounds of testing for each of our products. We have invested in two state-of-the-art in-house laboratories that allow us to conduct four rounds of testing, while most competitors test only one or two times. We test our raw materials, in-process batches, finish products, and product stability for each product.

Thinking Sustainably

We're thinking sustainably to protect our environment. We believe the environment should never be compromised for the sake of business gain. At Thorne, we believe that doing our part to protect the environment and its most valuable resources goes hand in hand with our product quality standards.
