A Serious Concern Across the Nation

High blood pressure continues to lead to serious health concerns for millions and millions of people. In fact, new guidelines suggest more people need to take action and quick. If you’re reading this, you’re already taking a step toward better health. But taking L-arginine Plus® can lead to even greater control toward better heart health.

While millions face serious health concerns related to their heart, L-arginine Plus® is one of the best support formuls available! 

Many people hope they can manage their heart health in a variety of ways. It’s important to remember to include diet and exercise in your routine, but there are times when those aren’t enough by themselves. And that’s where L-arginine Plus® comes in. 

L-arginine is the Key to Better Heart Health Support

Research continues to show the benefits of taking the amino acid l-arginine. 

L-arginine is proven to naturally boost nitric oxide production. Nitric oxide is produced within the walls of the blood vessels and helps to regulate how wide the blood vessels open, but production slows with age. That leaves the body more susceptible to problems related to heart health including high blood pressure and bad cholesterol. 

By adding l-arginine to the diet, you can boost declining nitric oxide levels and start to give the heart the support it needs. 

But L-arginine alone only does part of the job . . .

L-arginine gets absorbed by the body quickly and is used within a few minutes to create a quick boost in nitric oxide. That quick boost will quickly fade unless l-arginine is coupled with the amino acid l-citrulline. 

L-citrulline gets used by the body over time and extends the nitric oxide production from a few minutes to hours. 

Together l-arginine and l-citrulline improve nitric oxide production more effectively for better support for heart health and overall health. 

L-arginine Plus® is a unique formula that utilizes both l-arginine and l-citrulline along with key vitamins and minerals for the best support available for the heart.

Fire Station 69 A Platoon Captain Los Angeles Fire Department

“I have been a firefighter for over 33 years and have been exposed to lack of sleep for many years. A side effect of this was an elevated blood pressure. A leading cause of firefighter illnesses are cardiac related. I was always looking for a product that was not pharmaceutical to assist me in controlling my blood pressure, and then I stumbled across I-Arginine Plus when a co-worker brought some in for us to try.  After two weeks of using this product, I have lowered my Systolic number and my Diastolic number. A welcome side effect of this product may also be an increased amount of energy too. If you are looking for a product that may actually work in controlling an elevated BP, you may want to give I-Arginine Plus a try.”

Q. What is L-arginine Plus®?

A. L-arginine Plus® is a blend of the amino acids L-arginine and L-citrulline that increase production levels of Nitric Oxide (NO) in the body developed to help support your overall health. The efficacy of the amino acids L-arginine and L-citrulline have been validated by many scientific clinical studies. L-arginine Plus is a powdered formula you mix with water to make this powerful supplement drink. 

Q. L-arginine Plus® contains AstraGin, how will this benefit me?

(see http://www.getastragin.com/research.php)

Q. Why is L-arginine Plus® less expensive than other Nitric Oxide supplements?

A. Many suppliers charge what the market will bear. Our current business model, however, is to offer a superior product directly to you at the lowest possible prices. We hope you become a lifetime customer like so many others.

Q. Why are trace minerals important to the L-arginine Plus® formula?

A. L-arginine Plus® contains 100 mg of trace minerals in each serving. The trace minerals used in L- arginine Plus are alkaline, not acidic, making L-arginine easy to digest, unlike many competing brands. The trace minerals included in L-arginine Plus support healthy pH levels in the stomach and throughout the digestive tract. Unbalanced pH levels can upset some people when they first begin a Nitric Oxide regiment. Additionally, these trace minerals, independently of L-arginine Plus, are known to have a positive effect to improve overall health and well-being.

Q. Are there any age limits for taking L-arginine Plus®?

A. It is generally recommended that persons under the age of 18 should not use L-arginine supplements because specific studies on children have not been conducted. If you have any questions, please consult with a health care provider. 

Q. Is L-arginine Plus® safe to use?

A. The ingredients in L-arginine Plus® have a history of safe use. As with any dietary supplement, when being treated for a medical condition, pregnant or nursing, always consult with your health care provider regarding your use of L-Arginine Plus.

Q. What about the protocols? Are there any special instructions?

A. L-arginine Plus® is easy to use and requires no complicated protocols. Just mix one serving with water once a day (preferably on an empty stomach) and enjoy.

Q. Do you have to take L-arginine Plus® on an empty stomach to get the benefits?

A. For maximum benefit, L-arginine Plus® should be taken on an empty stomach. All benefits are certainly not lost by taking L-arginine Plus® with foods or beverages, but those benefits may be reduced.

Q. What is the product sweetened with? Can you describe the taste of L-arginine Plus?

A. L-arginine Plus® is sweetened with Xylitol. Xylitol is a low glycemic sweetener that occurs naturally in the body. High glycemic sweeteners can cause glycation, which can lead to decreased arterial flexibility. Unlike other sweeteners, xylitol has been shown to support saliva production and support overall oral health. With Xylitol included, L- arginine Plus offers a great-tasting grape flavor.

Q. Why is Xylitol Used in the L-arginine Formula?

A. L-arginine can cause the pancreas to release a hormone called glucagon. The pancreas produces glucagon as a means to increase blood sugar levels when they are too low. Glucagon makes the liver convert stored sugar (glycogen) to usable sugar (glucose) that is then released into the bloodstream. Using L-arginine along with xylitol, can keep L-arginine from stimulating the pancreas to release glucagon. Helping maintain balanced levels.

Q. How much do you charge to ship L-arginine Plus®?

A. Every order of 2 or more bottles of L-arginine Plus® is shipped free anywhere in the U.S.A.

Q. How long will it take for L-arginine Plus® to reach me?

A. A tracking number will be emailed to you once your order has been shipped.

Q. What is Sweta and what is it made from?

A. SWETA is a NATURAL sweetener (stevia). It is an extract from the stevia leaf and consists of a blend of steviol glycosides. It is more than 100 times sweeter than sugar, contains no calories and has a low glycemic load. Unlike our competitors (big MLM companies) who use artificial sweeteners like sucralose which can be unhealthy for you, L-arginine Plus is not artificially sweetened.

Q. You mention “natural” colors, what is actually used?

A. Grape Blue Powder – is a natural colorant made from high quality fruits and vegetables. It is manufactured using a unique processing technology that employs only water. It is free of chemicals, solvents, GMO ingredients and is Kosher certified.

A. Suggested dosage is to Mix 1 scoop with 4-8 oz water. Stir to dissolve. One scoop per serving of L-Arginine Plus powder first thing in the morning on an empty stomach or between meals. It can be taken up to twice a day. One scoop provides 5,110 mg of L-Arginine and 1,010 mg of L-Citrulline.
