ProArgi 9 Ingredients

Below is a comprehensive list of ProArgi9’s ingredients and a brief explanation of their relevancy.


L-arginine is an essential amino acid, meaning that it is amino acid needed by most humans depending on their developmental stage, according to the American Journal of Clinical Nutrition.

An amino acid is one of the substances that protein is made up, with a complete protein having eight essential amino acids.

Like most amino acids, l-arginine is found in the major protein sources; beef, chicken, poultry, and fish.

It can also be formulated in a lab, where it is then used in a wide variety of supplements and medicines, typically ones designed to benefit cardiovascular and sexual health.

The body converts this amino acid into nitric oxide. While the process is involved, nitric oxide’s main purpose is to increase blood flow, thereby providing cells with more oxygen.

While the focus of this article will be on the supplement ProArgi9 as a whole, it’s important to note that l-arginine’s benefits go beyond nitric oxide.

Arginine, a semi-essential or conditionally essential amino acid in humans, is one of the most metabolically versatile amino acids and serves as a precursor for the synthesis of urea, nitric oxide, polyamines, proline, glutamate, creatine, and agmatine.

The mention of glutamate and creatine will be of particular interest to athletes, as both of those are common pre-workout supplements.


L-citrulline is a non-essential amino acid (non-essential meaning that your body can make l-citrulline and doesn’t need food to formulate it, unlike the nine essential amino acids).

L-citrulline also works as a precursor for l-arginine and the conversion of nitric oxide. According to this study in the Journal of the International Society of Sports Nutrition involving cyclists, oral supplementation with l-citrulline has been shown to reduce muscle fatigue post-workout.

Because l-citrulline, like l-arginine, is a precursor to nitric oxide, it may help those suffering from high blood pressure.

Vitamin C

According to the National Institutes of Health, Vitamin C is integral to many of the body’s cellular functions, including wound healing, collagen, and tissue repair, as well as acting as an important precursor to neurotransmitters and protein absorption.

This is typically why nutritionists will recommend taking your iron supplement with vitamin C, or eating that sizzling steak with a huge spinach salad, maybe some strawberries thrown in for an extra kick.

Vitamin C’s benefits go beyond collagen and tissue repair; it may also play a role in cardiovascular health, though more research is needed.

ProArgi9 ingredients - vitamin B6

Vitamin B-6

Vitamin B-6 is a water-soluble vitamin found in plentiful amounts in beans, poultry, liver, dark leafy greens (hello kale!), and some fruits, in particular, papayas.

Vitamin B-6 is also a co-factor in controlling the amino acid homocysteine, which minimal research suggests may play a role in improving cardiovascular health.

Vitamin B-12

Found mostly in animal products, particularly liver, as well as spirulina and nutritional yeast, Vitamin B-12 is perhaps most commonly known as the mood vitamin.

Vitamin B-12 deficiency is especially common in those suffering from poor digestion,  pregnant or breastfeeding mothers, and vegans.

Like Vitamin B-6, Vitamin B-12 helps to maintain healthy energy levels and is a factor in energy conversion/metabolism.


D-Ribose is a natural sugar or carbohydrate (not to be confused with the kind of sugar we eat) found in our cells. D-Ribose plays an important role in preventing heart conditions and recovering from them.

How? While the process, like most biochemical processes, is complex, here are the basics. D-Ribose teams up with the chemical adenine to make a fancy molecule called adenosine triphosphate (ATP for short), one of the body’s major energy transporters.

A study in the journal of Circulation Research shows that low ATP levels are one of the factors behind heart conditions, so D-Ribose could be a powerful tool in the prevention and even treatment.

ProArgi9 ingredients

Pomegranate Fruit Powder

The pomegranate, red fruit with seeds in between white pith, has been cherished since ancient times throughout the Mediterranean and Himalayas for its health benefits.

Research is now showing that those benefits are more than just folklore or old wives’ tales, as pomegranate may play a significant role in preventing high cholesterol, as well as managing oxidative stress, according to the Advanced Biomedical Research.

Pomegranate fruit powder is by juicing pomegranates and then drying the juice, so it’s a very concentrated source of all the amazing benefits of this exotic fruit.

Grapeskin Extract

Grapeskin extract is likely included in this supplement because of its high resveratrol content.

Resveratrol, a phytoalexin antioxidant found in red grapes, has been shown to have both chemopreventive and therapeutic effects, including those of the skin”, says the Archives of Biochemistry and Biophysics.

Malic Acid

Love granny smith apples? You can thank malic acid. Malic acid is a naturally occurring compound responsible for the sour taste in fruits, particularly apples. Like D-ribose, malic acid plays an important role in ATP conversion and metabolism.


Xylitol is a sugar alcohol, usually derived from corn or birch trees. Because of its chemical makeup, xylitol does not break down like regular sugar.

Xylitol also plays a role in preventing tooth decay, making it a common ingredient in toothpaste and organic chewing gum


Here arrives the most mysterious ingredient of all: an artificial sweetener. Unfortunately, there is no research indicating that sucralose, also known as Splenda, is safe for humans to consume or recommended, despite being a popular sugar substitute.

While further studies are needed, research indicates that sucralose, despite being a zero-calorie sweetener; chemically spikes insulin levels (similar to regular table sugar).


Does ProArgi 9 Work?

While ProArgi9 itself is lacking in scientific research to back up its claims, many of the benefits of its ingredients are well-grounded in science.

Details On ProArgi 9 and Weight Loss

While ProArgi9’s main focus is improved endurance and cardiovascular help, it may indirectly help weight loss. Extra circulation/oxygen=improved energy levels=more activity=greater day-to-day calorie expenditure.


How To Use ProArgi 9 Products

You can purchase ProArgi9 in a large jug with a scoop or individual packets, typically best suited for those traveling.

Flavor options include mixed berry (the most popular), citrus, and grape.

When ready to consume, simply use the enclosed scoop to pour the powder into a cup, mix with 8 to 16 oz. of water and enjoy.

Some of the powder can stick to the bottom, so make sure to stir well or shake well if using a blender bottle.


ProArgi 9 Product Warnings

There are no known product warnings for ProArgi9 for humans. Because it contains xylitol, do not let your furry friends anywhere near it, as xylitol is deadly to dogs.

Is ProArgi9 safe


Is ProArgi 9 Safe?

For most individuals, ProArgi9 is safe to consume. However, if you are on any medications, particularly heart or blood pressure medications, please consult your healthcare practitioner before investing in ProArgi9.

Those who are sensitive or allergic to the artificial sweetener Splenda will want to avoid ProArgi9 as well.

Side Effects

ProArgi 9 Side Effects

Reported negative side effects from consuming ProArgi9 are minimal. Besides the above-mentioned issue with sucralose, those sensitive to alcohol sugars like xylitol (usually individuals suffering from already existent digestive conditions) may experience gastrointestinal upset or even diarrhea.

If you do decide to try it after consulting with a healthcare practitioner, start with a half scoop first to test your body’s reaction.


ProArgi 9 Lawsuits

There are no known lawsuits against ProArgi9.

ProArgi 9 Alternatives

There are more affordable l-arginine supplements available if budget is a concern for you, or if you cannot tolerate Splenda or xylitol.

Look for a supplement with a high concentration of l-arginine if you decide that ProArgi9 isn’t in your budget.

ProArgi9 is a legitimate supplement for enhancing cardiovascular health and improving endurance during and post-exercise.

It may also play a role in weight loss because of its metabolic benefits.

On the downside, ProArgi9 is pricey, especially if you make it a regular part of your supplement routine.

Whether or not it’s worth it is going to depend on you and your health and nutritional needs.

What Users Are Saying

“This was recommended by my Dr and I really think it makes a difference. I was consistently having cramping in my calves and I have not had cramps since I started taking it. I also think it gives me an energy boost. Flavor is ok.”

“The product is supposed to help reduce high blood pressure. I’ve been drinking it daily for over 32 days and so far my blood pressure has remained the same high figures as before. Perhaps continuing for a longer amount of time will produce the changes advertised. So far it has been disappointing.”

“Personally, I cannot consume this product as it upsets my stomach and digestive system. I bought this on a recommendation of a friend. It works very well for her but not for me.”
