Pruvit is a supplement company that develops products designed to help users lose weight quickly and efficiently. Pruvit claims it can ‘reboot your body’ in 60 hours, but does that mean it will leave you lighter? We looked at the science behind these products and found a serious shortage of evidence across the board.
Pruvit’s success depends on whether it can live up to claims, and our research team found a number of other factors that determine that. On top of that, we were taken aback by some user comments on side effects. Here’s the summary on whether this line is worth a shot.
First of all, Pruvit is a line of powdered weight-loss drinks aimed at eliminating fat. The supplements are supposed to suppress appetite, encourage fat loss, boost energy levels and increase strength. The products are available directly from the official website, and can also be purchased on Amazon.
They do have a research tab on their website, but it doesn’t exactly tell you much, and certainly doesn’t take you to any studies carried out on their products. Currently, Pruvit Keto OS Max is the most popular supplement in the line.
Recenrly, Pruvit renamed Keto Max to Keto//OS NAT.
This is how much it costs to start on the respective program. We always recommend trying a product before making a large investment.
= Initial product cost is less than $5
= Initial product cost is between $6 and $50
= Initial product cost is between $51 and $150
= Initial product cost is $151 or more
How Did Pruvit Start?
The company first appeared online in 2013. Pruvit products saw their start with the original Keto OS, which was the first consumer-based supplement drink for ketosis of its kind in the market.
However, that initial weight-loss aid was released amidst a flurry of less than favorable reviews, from complaints about the taste to claims that it was entirely ineffective.
Pruvit Keto Max is meant to correct the mistakes of its predecessor and improve on the parts of the formula which worked.
Since then, the company has gone on to release better products and work on its original Keto OS formula.
Pruvit now considers itself the world’s foremost ketone technology leader.
However, its status as a multi-level marketing company leaves some curious dieters in doubt about whether they can trust this corporation.
Now, Pruvit offers a variety of products, most of which claim to help you go into ketosis. The company also holds “Keto//Kademy” where individuals can learn more about ketones, their products, and how to get involved, though ticket prices start at $229.
Right now, Pruvit has an F rating for their pattern of complaints and ad reviews, although customer reviews leave the company at 3.5 stars, according to the BBB.
In August of 2018, the BBB issued an alert to the company due to its pattern of complaints and advertising policies. So far, no resolution has been met.

Pruvit Keto OS Max Claims
Pruvit Keto Max is made to supply the body with enough ketones to make it switch to a temporary state of ketosis, which helps keto dieters struggling with progress.
Supposedly, this product can kick you into ketosis within a mere 30-minutes, and if you keep drinking it, you’ll stay in that state easily.
However, the drink is meant to be a weight-loss aid, not a miracle product.
While the company which manufactures it states that most users will certainly see some degree of results when taking Keto Max; they also recommend that users try to limit their carb intake and eat healthy to allow the product to show results.
The entire concoction of Pruvit Keto OS Max is a proprietary lab-tested formula which is supposedly specifically designed for weight-loss. Ingredients in the new Keto//OS NAT formula include:
There is one main thing worth noting here, and it can be a bit confusing. The fact is that very few of these Pruvit ingredients seem to have anything to do with ketones, ketosis, or encouraging ketosis.
Two of the ingredients listed are amino acids L-Taurine and Fermented L-Leucine; a the conditional amino acid sulfunic acid, and fermented l-leucine isn’t naturally produced by the body.
L-Taurine is a conditional amino sulfonic acid.
The second protein listed is Fermented L-Leucine, an essential amino acid which the body does not naturally produce.
Interestingly, most of the conditions that L-Taurine and L-Leucine are known to help and the benefits that they provide are also supposedly received through a proper keto diet.
Another two ingredients on the list, Stevia and Erythritol, are natural sweeteners with low glycemic indexes. They’re good flavoring options for a weight-loss supplement drink which needs to have a palatable taste.
Beta-hydroxybutyrate, which is a patent-pending formula by Pruvit, is the only ingredient which is related to ketosis, and this is because it is a ketone body which has increased production during ketosis and can be used as an energy source by the brain and body.
But are Pruvit ketones enough to fully induce ketosis? Some weighing in on the benefits of exogenous ketone supplements are on the fence about whether beta-hydroxybutyrate alone can kick your body into a ketosis state.
The new Keto//OS NAT comes in a “charged” and “caffeine-free” version. The charged version contains the caffeine equivalent of 12 ounces of coffee.
Also, caffeine has been proven to help aid weight-loss efforts and reduce the size of fat cells when paired with exercise.
Therefore, the “charged” version of these drinks may help you lose more body fat if you work out while using this supplement.
Take note that minor ingredients, like flavoring or overall composition, may also vary very slightly across different Pruvit flavors.
There are three different Pruvit flavors for the Keto Max variety. The first flavor is Raspberry Lemonade, Swiss Cacao, and Maui Punch.
However, the new Keto//OS Nat version has more flavor options, including:
Fig Roll Up
All flavors come in caffeinated and caffeine-free version.
Does Pruvit Keto OS Max Work?
If Pruvit Keto OS Max can successfully induce ketosis, then yes, it works and will lead to weight loss. However, we maintain the idea that everyone’s body is different; therefore, just because the supplement works very well for someone else doesn’t mean it will yield the same results for you.
Your diet, activity level, and exercise regimen will all determine the effectiveness of this product. Pruvit reviews are highly positive on the company’s website, with plenty of testimonials claiming that this drink accelerated the weight-loss process.
The site claimed to help over 21 million people. However, even on the site, Pruvit now specifies that the Food and Drug Administration did not approve the products themselves or the statements of satisfied customers and cautions that users may receive different results.
Even when keeping that in mind, Pruvit has glowing testimonials on its site. However, there are plenty of reviews on Amazon which seem to show that it doesn’t work for everyone.
It’s about an even split down the middle of the number of people who praise and condemn Pruvit Keto Max, and that ratio varies depending on the seller. Then again, there are also some users who claim that some sellers on Amazon are selling fake versions of the product which don’t work.
Therefore, if you’re planning to buy this product from Amazon, you might want to be careful about your choice of a distributor. Doing a quick search of diet product review websites will also give you a mixed bag of results. Some sites claim the product works wonders.
Others claim they saw no results and experienced a ton of unfavorable side effects. Once again, the good to bad review ratio seems about even, so the only way to know whether you can use Pruvit for weight loss may be to test it yourself.
Benefits and Results
Pruvit Benefits and Results
Once again, it’s worth pointing out that these benefits will only happen if the product successfully puts you into a state of ketosis.
In short, these are the benefits that being in ketosis will produce. Therefore, the product must work for you to reap the benefits.
Increased Physical Energy
This is said to happen because your body will convert fat into fuel instead of carbs, and the body has a supply of stored, usable fat which can last weeks, if not months, which allows you to enjoy weight loss without feeling tired or hungry.
One study published in Metabolism “indicates that aerobic endurance exercise by well-trained cyclists was not compromised by four weeks of ketosis”. So if the supplement puts you into a ketosis state, then you may see increased physical performance, even in cardio or long-distance exercises.
Better Mental Focus
The more physical energy you have, the less tired and lethargic you feel, and the less brain fog you have, allowing for razor-sharp concentration.
As research from The FASEB Journal suggests, being in ketosis may allow for extremely precise focus because the brain is being fueled by ketones, which can improve brain function and cognitive abilities.
Loss of Body Fat
A ketosis state will naturally begin converting your body fat into fuel, meaning it is constantly burning your fat stores to give you energy.
Therefore, it’s only logical that your body will be burning a lot of fat through this method.
Studies published in the Metabolism journal show that, when paired with moderate exercise, those in a state of ketosis easily burn three times more fat than those who are not in that state.
Whether Pruvit Keto Max is an effective solution for weight loss depends on whether it successfully places your body into a state of ketosis.
If it can do so, then weight loss is scientifically guaranteed. When your body is in a state of ketosis, it burns the fat you have stored, naturally leading to decent quantities of weight loss.
Numerous randomized and controlled studies, which are the most reliable diet and health research method, published in the New England Journal of Medicine have shown a ketogenic diet or any similar low-carb, high-fat diet helps with weight loss.
If the Keto Max supplement does, in fact, induce ketosis, then it will help you lose weight, especially if you eat a healthy low-carb diet on the side and couple it with at the very least, some mild exercise.
Keep in mind that if you are building muscle while in ketosis, you may begin gaining healthy weight due to muscle mass but will continue to burn fat; so, you will still be losing inches and becoming leaner and more toned.
One fact that may be a cause for concern is that Pruvit results have never been medically or scientifically studied.
While there are plenty of known, proven benefits of being in a state of ketosis, it appears that there are no significant studies on using Pruvit for weight loss, meaning that as a product, Pruvit Keto OS Max is far from scientifically backed.
Without research to back it up, the evidence which could support a Pruvit guarantee is greatly lacking, and likely the reason why Pruvit products have received negative reviews which describe their lack of effectiveness.
However, the company claims to have improved their formulas since then.
On the other hand, Pruvit’s website claims that several specialists in exercise, diet, and health work with the company and approve of its cause and mission.
However, these specialists often represent the company and talk about Pruvit’s benefits on the company’s social media, which might slightly increase the brand’s credibility, even though there are no Pruvit guarantees listed on any site.
Pruvit also has a blog on their website dubbed “Ketone Conversation.” There, they primarily post healthy recipes using their products. This apparently may give you new ideas on how to incorporate their products for better ketosis, though success for weight-loss is rarely mentioned.
Pruvit Before and After
The Pruvit before and after section on the company’s website suggests that many people, ranging in age from 18 to 50 years old, have benefited from the product and saw weight loss results.
For some, the product helped keep them in a state of ketosis that was necessary for their health conditions. For others, the product helped them lose a lot of weight, even up to 50 lbs.
Positive Pruvit reviews from other websites like Amazon and dieting blogs also detail weight loss successes which involve 10 to 40 lb. weight loss, which is a promising start.
However, negative reviews state that the product either did not help at all or caused a slight weight gain, which could be caused by not following a low-carb diet or limited exercise, a counterfeit product, or the supplement simply not working well with the reviewer’s body.
How to Use Pruvit Keto Max
This product is extremely easy to use and barely requires any effort, especially since Pruvit ingredients are already all mixed together in powder form when you buy it.
Just rip open your pre-packed Keto Max powder and pour it (or one heaping scoop of it, if not pre-packed) into about 12 to 16 oz of cold water.
Mix well by roughly shaking or stirring until it looks well combined.
How often should you take Keto Max? That depends on what you aim to achieve.
Consuming one daily serving is sufficient for a therapeutic dose, but if you want to reach optimum results, then taking the drink twice a day–in the morning and evening–is likely the best option.
You don’t have to drink it after or before eating; there are no specific requirements other than that you must drink it!
Known Pruvit results dictate that you will likely need to continue taking this supplement if you want to maintain your weight loss.
The Pruvit Diet
To achieve the best results with Keto Max, you may still need to regulate your food intake.
While some users claim they can lose weight easily by taking the supplement alone, this varies from person to person.
Pruvit’s website recommends a low-carb diet in conjunction with the supplement. If you’re really looking to use Pruvit for weight loss to a more serious degree, a limited intake of around 100g is said to be sufficient.
What if you want to wean yourself off this supplement after some time?
To maintain the weight loss, you will likely have to follow the keto diet, which involves maintaining a moderate calorie deficit and consuming a diet that consists of 5% carbs, 25-35% protein, and 60-70% healthy fats.
Basically, to reap the full benefits of Keto Max, a Pruvit diet of sorts may be necessary. And, to maintain your weight loss after you quit using the supplement, a ketogenic diet is needed.
Any Pruvit Lawsuits?
Currently, there have been no lawsuits that negatively implicate Pruvit Keto OS Max or the effectiveness of any Pruvit products.
Potential Pruvit Side Effects
While there’s no mention of side effects from Pruvit products, we have to look at the ingredients. Some potential side effects of Pruvit ingredients may include:
If they successfully enter the ketosis state, users may also experience the common side effects associated with ketosis.
Note that these side effects will go away in a couple of weeks, once the body becomes accustomed to burning fats instead of carbs. You can lessen these side effects by drinking plenty of water, consuming plenty of fiber, and eating plenty of salt. These side effects include:
Pruvit Product Warnings
Pruvit does not list any specific warnings for this product on its website. Here is the general warning included on the site:
As with any new supplement, consult with your physician before using.
The company states that if you are using any prescription or over-the-counter medicines, are unaware of your current medical condition, have any pre-existing medical condition(s), to consult with your physician before using this product.
Build up to a full serving slowly to avoid stomach discomfort.
Pruvit Keto//OS NAT
Pruvit no longer sells Keto Max and has re-named it Keto//OS NAT. The two products have similar ingredients, but the newer version comes in more flavors.
According to the official website, you should use the caffeinated version of Keto//OS NAT before 9 am, drink plenty of water during the day, then use the caffeine-free version before 7 pm.
Apparently, the product’s nutritionally advanced technology allows for healthy cell function, increased focus, appetite suppression, and accelerated ketosis.
While Pruvit products may have been the first of their kind to enter the diet market; since then, plenty of decent alternatives offering similar features and benefits have surfaced.
Some of the most commonly known Pruvit supplement alternatives are Perfect Keto and Prototype Nutrition’s Ketoforce and KetoCaNa.
Both contain similar ingredients to Pruvit Keto OS Max and have similar good to bad review ratios.
Another Pruvit alternative is to work hard to achieve ketosis independently.
Of course, this involves a lot more work and a strict dieting regimen, but of all diet options, the ketogenic diet is one that delivers rapid results and has a lot of scientific backing.
For long-term results, the consensus among medical experts and researchers about how best to lose weight and keep that weight off is simple: eat healthily and exercise often.
What Users Are Saying
“I ended up in the emergency room with extremely high blood pressure after taking this product for 21 days (I have never had high blood pressure in my life). The sodium content in one packet is 70% of your daily recommended intake. There is inconclusive science behind taking BHB Ketone Salts – BE CAREFUL!”
“Works well, have lost 40 lbs from this product alone in the past two years.”
“I didn’t lose, but I didn’t gain either.”
The Bottom Line on Pruvit
