Perfusia-SR by Thorne Research is a sustained-release form of L-arganine‚ a semi-essential amino acid that has been shown to promote cardiovascular health. Thorne Research designed this L-arginine supplement to support wound healing‚ immune function and heart health. Possibly the most important feature of this amino acid is that is serves as a precursor to nitric oxide.

The Role of Nitric Oxide

Once L-arginine is converted by the vascular endothelium to nitric oxide‚ it starts helping the endothelial cells (inner layers of the arteries) to become more resistant to damage caused by oxidation. This reduces the chance of harmful substances sticking the endothelial wall. Many studies have shown that people who produce adequate amounts of nitric oxide are more likely to maintain good cardiovascular health than those who have low levels. In the absence of adequate L-arginine (and the subsequent nitric oxide)‚ arteries may become restricted‚ which can prevent blood from flowing properly throughout the body – especially to organs and extremities.

Furthermore‚ a double-blind study illustrated that men with high nitric oxide metabolism are less likely to have reproductive health issues than those with low levels.

Adequate L-arginine intake promotes:

  • Relaxed arteries which result in better blood flow and normalized blood pressure

  • Better overall heart health
  • Erections that occur naturally in the normal course of intimacy

Like many other amino acids‚ L-arginine is a building block of protein‚ but unlike the others‚ L-arginine has also been shown to expedite wound healing. Studies have shown that supplementing with L-arginine shortens healing time and strengthens the damaged tissue. In addition to cardiovascular health and wound healing‚ L-arginine is involved in many areas of metabolism and physiology. It helps regulate the flow of neurotransmitter chemicals growth hormone‚ insulin and glucagon (which raises blood sugar) and has an impact on endocrine function.

The Thorne Research Difference

Generally‚ L-arganine is absorbed and metabolized very quickly‚ which means that you would need to take many capsules throughout the day to keep your levels steady. However‚ Thorne Research has formulated its L-arginine to be released slowly so that optimal levels are maintained for hours. With Thorne’s Perfusia-SR product‚ you only need to take a dose two times per day to achieve the best potency.

In addition to the studies done on L-arganine and nitric oxide‚ studies on Perfusia-SR have illustrated an increased flow of blood to the heart and extremities. Similar studies show that Perfusia-SR may be effective at normalizing blood pressure and improving elasticity of the arteries. One study showed an improvement in the blood flow of heart patients taking Perfusia-SR.

Thorne Research strives to provide pure‚ high-quality supplements to people looking to enhance their health and well-being. Its products are commonly used in prestigious research studies‚ and are recommended by many doctors and health care practitioners. The company always goes the extra mile to ensure that Thorne Research dietary supplements are safe and effective for immune-compromised‚ allergic‚ and chemically sensitive patients.

Great way to boost energy.
February 26, 2013
The boost in energy is so significant, I don't take Perfusia-SR past noon because I end up staying up too late. As you get older, you can't under estimate the importance of circulation. Perfusia-SR is time released L-Arginine which is important because L-Aginine has only a couple hour half-life in the system.
Works great for a variety of bodily functions.
L-Arginine will express herpies symplex. For people who are predisposed to herpies outbreaks or cold sores, this product must be taken with L-Lysine. But they must be taken 4 hours apart, otherwise, they will cancel each other out.

Arginine for blood pressure
March 2, 2012
My naturopath suggested trying arginine to help with controlling my blood pressure. Using Thorne Perfusia SR for several months now, I've been able to stop taking nifedipine, which can be harmful to kidneys. I've been very pleased with Pure Formulas for offering quality products at good prices with no shipping charge.

Originally saw this in the Naturopath pharmacy in Luey town. Please don't raise the price cause my insurance does not cover it, and there are other supps that I must take as well.
So far it seems to be FREE of side effects.
Will have to cough up the dinero if I am going to enjoy what little quality of life that may be left with Perfusia.

Since my prostate surgery in 2002, I have suffered from ED. A doctor I know recommended Perfusia-SR as a possible help for that. After 2 months of using it, I must say that it has helped quite a lot and I will continue using it.

Worked for me.
March 20, 2011
I have been on Norvasc without satisfactory results. After trying a couple of other blood pressure meds to add to it and suffering the side effects, I tried the Perfusia a naturopath had given me a year ago. At that time I wasn't yet on the Norvasc, and the Perfusia on its own didn't work for me. So taking the two together has really done the business. I had blood pressure in the 140s with the Norvasc alone, now my average is 122/77. I have no salt sensitivity now, there are no negative side effects and rather than feeling drowsy I have more energy.
Lowered my blood pressure
Absolutely nothing.

Improved circulation to extremities
March 19, 2011
This is probably the best Arginine supplement on the market. I take Thorne Perfusia to increase blood-flow to my extremities, and it makes a noticeable difference. I experimented with it while skiing, and my feet, hands, and ears seemed to stay warmer. I also work in a cold environment, and I notice that I feel a bit colder when I forget to take my Arginine. I hear that sustained-release is what you want, otherwise your body will quickly utilize whatever Arginine you ingest and the effects will only last ~30 mins or so. Pure Formulas has the best price I've found for Perfusia.

New to me but Doctor's orders
February 16, 2011
In dealing with my fuzzy headed memory problems my Dr. recommended Perfusia after giving me a test to check out my blood flow - this test revealed that the flow through my large blood vessels was within normal limits but in my small vessels like my hands and feet and brain it was borderline normal - He recommended I come and see him in three months but in the first three weeks the pain in my hands and feet has become much less and I assume the blood vessels in my brain are becoming more relaxed too allowing for greater blood flow to my brain - Mary Jane Sander
it appears to be working

L-Arginine with a twist!
January 19, 2011
As an aging male I find that certain supplements help out the heart and circulatory system and L-Arginine is certainly one of them. Thorne Research has made it that much better by making a sustained-release capsule called Perfusia-SR. Although I've only used it for a couple of weeks, I already notice the difference in how I feel when I perform different tasks. I decided to give it a try after hearing about it from Suzy Cohen's Dear Pharmacist website. Thanks to Suzy for the recommendation and many thanks to Thorne Research!
The fact it is sustained release, so that it stays longer in my bloodstream longer throughout the day.
It doesn't make my breakfast for me? I don't know! There is nothing to dislike.

Was taking perscription, attenolol to lower blood pressure and didn't like how I felt. I saw my holistic health M.D. who recommended Perfusia SL which brought my blood pressure back to normal readings for the last 3 years. I wouldn't be without it. Fortunately, Pure Formulas.com makes this affordable for me.
