When most people mention Pruvit, they are actually referring to the Pruvit KETO//OS supplement.
It is perhaps the most popular keto supplement out there.
Anyone following a keto diet has probably heard about exogenous ketones.
With the keto diet becoming increasingly popular, so are exogenous ketone supplements.
These supplements are marketed for their ability to provide the powerful health benefits of a ketogenic diet without actually observing a strict low-carb diet.
Still, most manufacturers would advise taking ketone supplements to complement a ketogenic lifestyle.
Pruvit is claimed to be the leading brand in the exogenous ketone supplements market.
Keto OS is the flagship exogenous ketone supplement produced by Pruvit Ventures, Inc.
According to the company, taking Keto OS helps improve mood, increase strength and energy, boost focus, improve sleep, and support fat loss.
While some scientific studies support the effects of ketone in humans, there is little evidence supporting Pruvit’s claims.
As is the case for most (if not all) ketone supplements, there are many questions concerning Pruvit Keto OS regarding safety and effectiveness.
This review will explore what evidence there is on exogenous ketone supplements with a particular focus on determining whether keto os by Pruvit actually delivers on the promise of improving mood, strength, energy, sleep, focus, and fat loss.
It would be interesting to find out also what key ingredients go into the supplement’s formula.
We’ll lift the lid on what safety concerns and potential side effects exist.
And we’ll highlight whether buyers actually experienced the advertised benefits.
Ultimately, this review builds up to a basic familiarization of the product and an in-depth understanding of how it works (if at all) so you can make an informed decision.
Truthfully, this review is not for everyone.

Pruvit Keto OS Review – Does it Really Work?
Pruvit: Background & Product Guide
Pruvit (Ventures, Inc) is a US-based nutritional supplement manufacturer and multi-level marketing (MLM) company founded in 2012.
It is regarded as one of the pioneers of exogenous ketone drinks and revolutionary ketone technology in the United States.
Pruvit currently offers an entire product line dedicated to ketosis.
We may only touch on a few of their ketone powder supplements, starting with their main offering, Keto OS.
>>Keto//OS (Operating System) was the first-ever ketone supplement line offered by the company. This brand came in two different flavors but is no longer available:
- 2.1 Orange Dream
- 3.0 Chocolate Swirl
>>Keto//OS MAX was an improvement of the flagship Keto OS line. Keto Max was considered Pruvit’s best formula because it offered better bioavailability. It is available in the following flavors
- Maui Punch
- Swiss Cocoa
>>Keto//OS NAT (Nutritionally Advanced Technology) is their latest brand, containing the most “high tech” ketone salts formula as an exogenous keto supplement can get. It is offered in a variety of unique flavors, including (but not limited to):
- Raspberry Lemonade
- Heart Tart
- Lime Time
Pruvit also offers other keto products, some of which may not contain pure ketones but are specially engineered and blended to allow for faster conversion into ketones.
- Keto OS Pro
- Pruvit Reboot
- Keto Kreme
- Unleashed Blue Ocean
Pruvit OS products contain patent-pending ketone salts, which make up the bulk of the product formula.
Ketone salts are simply ketone bodies bound to mineral salts such as calcium, sodium, and magnesium.
Exogenous ketone salts are engineered to elevate blood ketone levels which are then converted into an energy source for the body.
In nutritional ketosis, the body and brain break down fatty acids to naturally produce the energy-generating molecules we call ketone bodies.
It is important to note that taking exogenous ketones induces ketosis without triggering the natural production of ketones as it is in nutritional ketosis.
Pruvit keto supplements are claimed to offer plenty of benefits associated with being in a state of ketosis.
Different Pruvit keto os products contain a range of different ingredients and offer varied benefits.
Keto OS may bring about the following benefits:
- Reprograms the body to derive its energy from available ketones instead of blood glucose
- Boosts athletic performance, energy levels, and focus
- Enhances cognitive function and increase mental clarity
- Promotes optimized cellular regeneration and DNA repair
- Increases appetite suppression and aid in weight loss
- Helps achieve a deeper, restorative sleep
To better understand what Pruvit Keto does for you, we sought to evaluate the main active ingredients.
Here are some of the ingredients you’ll find in most Pruvit keto os supplements:
- Beta-Hydroxybutyrate (R-BHB)
- MCTs (medium-chain triglycerides)
- C-Med 100®
- Amino Acids (L-arginine, L-leucine, L-taurine, L-tyrosine)
- Minerals ( calcium, magnesium, sodium, etc.)
- Vitamins (B6, B12, etc.)
- Ascorbic Acid
- Malic acid
- Caffeine (option)
In this review, we will only discuss the primary active ingredients.
1) Beta-Hydroxybutyrate (R-BHB)
Pruvit OS supplements contain beta-hydroxybutyrate ketones typically packed in the N8 patent-pending formula.
N8 Bioavailability blend is Pruvit’s proprietary blend of ingredients specifically formulated to enhance the efficiency and absorption of ketones.
The N8 blend is marketed for its ability to quickly deliver a fast-acting, deep state of ketosis for an extended period.
The R-BHB ketone salts are the primary ingredients in Pruvit’s N8 bioavailability blend.
These ketone salts have been shown to boost levels of blood ketones and effectively help support the body’s natural ketone production.
Supplementing with beta-hydroxybutyrate results in increased and sustained energy as the body becomes conditioned to use ketones as fuel.
New research has demonstrated that Beat Hydroxybutyrate may be much more than just an efficient fuel source for the body.
As it turns out, the benefits of R-BHB salts run long.
According to Pruvit, their keto os formula may provide weight loss benefits, aid in appetite suppression, help fight oxidative stress, and prevent age-related cognitive decline.
Sourced purely from coconuts, medium-chain triglycerides (MCTs) are a special type of fat that the body can store as body fat or burn for energy.
Pruvit supplements like Keto//os PRO are packed with a purified, powdered version of regular MCT oil known as C8 MCT.
C8 MCT is a medium-chain fatty acid derived from coconuts.
Supplement manufacturers preferred this purified version of medium-chain triglycerides (MCTs) because it is more metabolically active.
You will remember that fat metabolism happens in the liver.
Here, fats such as triglycerides are oxidized to produce energy-carrying molecules known as ATP (adenosine triphosphate).
In C8 MCT fatty acid supplementation, the liver takes fatty acids and turns them into ketones.
However, MCTs have been shown to benefit the body and brain in more ways than just providing a source of energy.
Current research has shown that MCTs could be beneficial for weight loss.
While more research is still needed, the results obtained from available research are promising.
Particularly, MCTs have been associated with increased levels in two gut hormones that play a central role in appetite regulation; peptide YY and leptin.
3) C-Med 100®
Pruvit OS contains a novel extract of the Amazonian vine called Uncaria tomentosa (a herb also commonly known as Cat’s Claws).
Pruvit calls the blend C-med 100, which is part of their proprietary ketone energy technology.
The use of the exotic herb in Pruvit ketones has little to do with the primary goal of providing exogenous ketones to condition the body to source energy from burning fat.
That is not to say, however, that there are no benefits to be gained.
The company claims that the extract may function to promote mental clarity and improve cognitive functions.
Though research is limited, Cat’s Claws used in the C-med blend has been shown to support the immune system and aid in DNA repair.
Safety studies could not find any side effects associated with using the medicinal herb native to the Amazon basin.
It was interesting to learn that the use of Cat’s Claws goes back in medical history to when the Campa Indians used it to treat different ailments.
4) Amino Acids
Other than keto salt (R-beta Hydroxybutyrate) and C8 MCT fatty acid, Pruvit OS contains an assortment of ketogenic amino acids.
Essentially, these are amino acids that can be broken down to produce energy-generating keto bodies through a complex series of reactions called the citric acid cycle.
When glucose is insufficient, ketones produced from amino acids may provide the body with energy through the process called ketogenesis.
Pruvit exogenous ketone supplement contains one of the two essential amino acids known to be exclusively ketogenic; fermented L-leucine.
L-lysine is the other exclusively ketogenic amino acid that may be derived from most keto diets.
L-Tyrosine is used in exogenous ketones for its catabolic reactivity as both ketogenic and glucogenic amino acids.
Amino acids have also been used in keto supplements for their ability to decrease obesity and insulin resistance.
However, there is little research illustrating this effect, and the usage of amino acids in this regard remains disputed.
Evaluation of Claimed Benefits
Pruvit Ketones are claimed to be based on a revolutionary proprietary ketone energy technology.
The company states that its advanced macro nutritional energy technology could help users improve moods, concentrate better, boost mental energy, and promote cellular regeneration.
While the company insists that their exogenous ketones formula isn’t designed to help you lose weight, they mention that exogenous ketones have an appetite suppressant effect that could contribute to weight loss.
We could not find any scientific research to support Pruvit’s claims since no single study has been done on their keto os supplements and they also had some complaints (and even some Pruvit lawsuits as well) as they are having continuous problems with the Keto OS.
Here’s a little bit of what we found:
- Current studies suggest that the brain prefers ketones over glucose as a fuel source. Larger, robust studies have established that the brain uses ten times more energy than any other organ, accounting for 20% of the total energy produced. Considering that ketosis provides a steady production of energy that the brain can use, exogenous ketones may support cognitive functions.
- Some small preclinical studies in mood and neurodevelopmental disorders demonstrated the antidepressant and mood stabilization effects of nutritional ketosis. However, it is not clear whether exogenous ketones could provide any significant mood stabilization effects. Additionally, scientists have warned that not everybody adjusts well into ketosis, and low-carb diets may cause keto flu, marked by confusion, irritability, and sleep disturbances.
- Although research studies have turned up mixed results, there are several ways in which BHB salts and MCTs may aid in losing weight fast.
- Scientists are still studying how exogenous ketones affect people with diabetes. One small study found that it helped lower blood sugar levels in people with type 1 diabetes.
Based on the research findings, we cannot refute the fact that supplementing with exogenous ketones may provide some health benefits.
As such, keto os supplements may provide us with some of the claimed benefits.
However, it is not clear whether keto os supplements (or other exogenous ketones like perfect Keto) may produce any of the discussed benefits on their own.
It has been suggested that exogenous supplements work best when combined with a low-carb diet.
However, keep in mind that the primary active ingredients of Pruvit’s exogenous ketones are tied up in proprietary blends.
As such, it is difficult to determine how much of each component went into developing the blend.
Therefore, it’s impossible to know if the constituent ingredients are provided in the appropriate dosages to make any significant impact.
Pruvit claims that formulators can make informed choices to combine the individual components such that the resulting product is safe and highly efficient.
Next, we investigate the product for safety and report on any side effects worth noting.
Safety & Side Effects of Prüvit Keto
From a biochemical perspective, Keto//os seems like a safe product.
However, that is not to say that the supplement is entirely without any risks or unpleasant effects.
The side effects you’d expect with Pruvit ketone supplements are not different from what you would experience with other keto systems.
Bad breath is perhaps the most evident side effect associated with elevated ketone levels in the body.
Other side effects of these supplements are experienced when they are combined with a non-ketogenic diet.
Amateur keto dieters may experience several symptoms, including irritability, foggy brain, headache, and nausea, which have come to be collectively known as keto flu.
Keto aficionados may potentially slip into a life-threatening state called ketoacidosis.
Basically, ketoacidosis is a severe metabolic state caused when uncontrolled production of ketone bodies elevates the levels of blood acids (excess ketones) such that natural insulin production cannot effectively allow blood sugar back into the cells.
Symptoms include excessive thirst, frequent urination, nausea and vomiting, abdominal pain, and confusion.
When following a keto diet (or low carb diet), there is a high risk of having low blood sugar levels.
That is why diabetic individuals are advised to consult their treating health care providers before taking ketone supplements.
Keto OS consumers may also experience intense diarrhea, increased flatulence, and severe stomach pains.
The long-term effects of ketone supplementation are unknown since research on exogenous ketones is still in its infancy.
Perhaps, future scientific research may produce relevant information to understand the application and limitation of exogenous ketone supplements.
Pruvit Keto Reviews from Customers
You will notice a lot of fake reviews out there.
Somehow, I have come to expect this of most dietary supplements.
Carefully souring the internet, you will not fail to come across some honest reviews on Pruvit.
I found that most customers were satisfied with the results they got from their Pruvit products.
Other than the reviews and testimonials through the Pruvit website, tons of online reviews have indicated the weight loss effects and improved athletic performance.
I’m not just talking about the before-and-after pictures you see online.
I was immediately impressed with the company’s [B-minus] rating on the Better Bussiness Bureau (BBB).
The BBB organization has been at the forefront of advancing marketplace trust in the United States, Canada, and Mexico.
BBB tracks Pruvit complaints and rates the company based on reliability, performance, and how it conducts business.
As such, Better Bussiness Bureau (BBB) is an excellent resource for anyone looking to understand whether the brand is in good standing.
That being said, there were a few Pruvit negative reviews.
Most negative reviews centered around the product’s premium pricing.
A few customers mentioned that they could not bear the taste.
However, most other keto dieters praised Pruvit for making their ketone supplements quite flavourful.
I figured the taste issue is highly subjective, reflecting the individual’s personal preference rather than indicating a flaw with the product.
Here’s a look at what Pruvit customers are saying about the KETO//OS supplements.
I want to give props to customer service. I see a lot of complaints on here and not a lot of positive feedback. I have had a couple of issues over the past two years …not getting the correct flavor…having an issue with a missing package. I have always received a prompt reply and a solution to the issue. Thank you! – Teresa P
Love the taste… too expensive for what’s in it – Natalie Stovall
Fasting was easier than I thought. With this product, you don’t suffer from hunger it keeps you energetic and focus. Definitely will do it again. – Ada Navarro
Serving Instructions & Recommendations
Pruvit exogenous ketones are sold in small packets meant to be mixed into 12-16 oz of cold water.
Pruvit recommends a therapeutic dose of 1 serving or 2 servings of Keto//OS daily for “optimal performance.”
Ideally, one serving should be stirred in the morning before taking breakfast.
The second serving can be mixed in the evening a few hours after the last meal.
In addition, the manufacturer suggests drinking lots of water throughout the day to stay hydrated.
Using keto os products may bring about water and mineral depletion due to its diuretic effect.
Increasing water intake and supplementing with essential minerals and vitamins helps replenish what was lost and hold back keto flu symptoms.
For optimal results and to help you enter ketosis faster, ketone supplementation should complement a ketogenic diet.
Typically, this means…
- Limiting carb intake as much as possible by gradually switching to a low-carb, high-fat diet.
- Filing up on healthy fats such as fish, eggs, wholegrain, nuts, etc
- Moderating protein consumption
- Practicing intermittent fasting or reducing your food intake
Cost & Where to Buy
Pruvit supplements are definitely premium products.
The total cost will depend on the number of packets ordered and the type of flavor chosen.
You can buy Pruvit ketos os on the official Pruivitnow website at a minimum order of 20 servings.
Subscribing to the Smartship (automatic shipment) membership program offers many options to save money, including a discount of up to 22%.
Pruvit keto os also retails on online marketplaces like Amazon.
The benefit of buying your keto os products from Amazon is the option of ordering as little as 3 packets.
This means that you don’t have to spend a lot of money at once.
Buying from the manufacturer’s website comes with the benefit of the 90-day money-back guarantee, which offers a full refund if you’re not satisfied with the product.
No doubt, supplementing with exogenous ketones may translate to better health.
Some evidence shows that these supplements may boost energy levels, enhance cognitive functions, and max athletic performance.
There are benefits to be gained on the journey to losing weight, as well.
However, supplements with exogenous ketones are not magic pills by any means.
And, while most of the mentioned benefits are scientifically established for ketogenic diets, more research is needed to provide conclusive results on the benefits of using exogenous ketones.
That said, Pruvit seems to have done their homework right.
Being the leading brand in keto, Pruvit products appear to be thoroughly researched, well-thought-out, and keenly formulated with the end-user in mind.
Compared to the next big brand in Keto (Perfect Keto), Pruvit easily ranks better for:
- Fast-acting exogenous ketones
- More flavors, better tastes
- Superior brand recognition
- Loyal customer base
Ultimately, whether you go for Perfect Keto or Pruvit, you should be in some form of ketosis even if you are not on a ketogenic diet.
But I figured that you have to be willing to stick to a ketogenic diet of sorts if you wish to gain meaningful results from products like Perfect Keto and Pruvit.
Frequently Asked Questions (FAQs)
When should I drink Pruvit exogenous ketones?
Since drinking ketones is associated with boosted energy, manufacturers often recommend taking keto beverages when you feel a drop in energy.
Companies like Pruvit have suggested taking keto supplements to enhance mental functioning during the day.
The company suggests that you may drink keto to suppress appetite and cravings for unhealthy foods.
Though not a weight loss system, this benefit of Pruvit ketone supplementation has helped overweight individuals lose weight.
The most common recommendation is to take ketones to complement a keto diet.
Exogenous ketone supplements are most beneficial during the transitioning phase to a keto lifestyle as they help ease the symptoms of keto flu.
How long will I be in ketosis?
Keto//OS is said to put you into full ketosis within 60 minutes of drinking it and typically last for a few hours.
Typically, ketogenic diets bring about a slow rise in ketone levels, whereas exogenous supplements put you into the intended state of increased ketone levels a bit faster.
According to Pruvit, Keto//OS powder will help you get into ketosis quicker when used to complement a ketogenic diet.
Because of this, many keto dieters drink ketone beverages after a cheat day to help them get back into ketosis.
Will Keto OS supplements help me lose weight?
According to Pruvit, their ketone operating system is not meant to be a weight loss system.
However, considering that maintaining a state of ketosis has been associated with suppressed appetite and reduced cravings, weight loss is a potential bonus.
Some ingredients in Keto//OS have been shown to enhance the fat-burning effect that occurs when you're on ketogenic diets.
As such, Pruvit OS may produce weight loss benefits.
Which Pruvit Keto OS product should I buy?
There are various Keto OS supplements in a unique array of flavored options.
All Pruvit ketone supplements work to boost blood ketone levels.
When choosing Pruvit OS supplements, consider the ingredients used in your product choice.
Be sure that you are not allergic to any of the constituents present in the formula.
You may also choose based on taste and flavor preference. Keto max, in particular, is a favorite for the fruit punch flavor in the Maui punch option.
Another consideration would be to choose between the charged version (caffeinated) and the decaf version (completely caffeine-free).
Is it safe to stop taking Pruvit os exogenous ketones?
It is okay to quit the keto lifestyle if it isn't working for you.
You will want to be careful when making the transition off keto supplements.
Adding carb back to your diet may lead to blood sugar spikes and weight gain.
The safe way to go off Keto is to gradually minimize fat intake while slowly upping intake of wholesome carbohydrates, lean proteins, and vegetables.
