Pruvit Keto OS is a supplement marketed by a multi-level marketing (MLM) company called Pruvit.

The main difference between MLM companies and more conventional ones is the way they market their products.

MLM companies recruit people who are willing to work as self-employed distributors and then pay them a commission on any sales they make.

In addition to any money they make from their own sales, MLM distributors get a commission for sales made by distributors they bring into the business.

They also get paid commissions for the sales made by the people their recruits bring in.

As with most other MLM companies, Pruvit places as much emphasis on selling its business “opportunity” as it does on its products.

No doubt its distributors, which are referred to as promoters, do the same thing.

The commission structure allows distributors to receive commissions on the sales made by distributors several levels down their “downline”. That’s what puts the multi-level in MLM.

In theory, MLM distributors should be able to become super-rich. Some do, but most operate on or just below the breadline. As a business concept, MLM has many flaws. This is not helped by the fact that typical MLM products tend to offers a combination of poor quality and high prices.

What Is Pruvit Keto OS?

Keto OS is the short name for Ketone Operating System.

It’s basically just a drink mix that designed to manipulate your body’s natural operating system and cause it to rely on fat for energy instead of protein and carbs.

After the switch is made, Pruvit Keto OS users are told they “may” attain several key benefits:

Pruvit Keto OS Possible Benefits

  • Better mental focus
  • Fast, sustainable energy
  • Help with abdominal fat loss
  • Faster post-workout recovery rates and strength increases
  • Improvements in mood
  • Better sleep quality

Note the fact that Pruvit is not promising any of these things. It’s only saying they may happen but most people visiting the site are unlikely to notice that nothing definite is being promised.

Pruvit Keto OS is an incredibly expensive product, so customers who do buy it are paying a lot for a maybe. That’s a fact.

How Does Pruvit Keto OS Work?

As the name suggests, Pruvit Keto OS is intended to cause a state of ketosis. When this state is reached there are extra ketones circulating in the blood. Hence the name.

Ketosis is a natural condition that can be brought on by sticking to a diet that is very low in carbs but contains higher levels of fat.

Based on Ketogenic Diet

It’s called the Keto Diet and, although it’s very controversial, it’s also got a lot of fans.

When you are in a state of ketosis, certain benefits are likely to occur. The most beneficial ones are:

  • More energy
  • Less hunger
  • Faster metabolism
  • Fat burning

Some research suggests a lot of the fat that is burned is likely to come from the abdominal area, so the Keto Diet has some obvious attractions. [SOURCE]

Like many similar products, Pruvit Keto OS is a supplement that contains ingredients that are intended to add extra ketones to the blood.

It would be nice if all the aforementioned ketone benefits could be attained without the need for a special diet, but there is no real evidence that they can.

Key Ingredients and Blend Potential

Pruvit doesn’t make it easy for potential customers to discover what the product contains.

In place of a list of ingredients it provides a supplement fact sheet that states the products provides zero grams of fat, zero protein, and zero vitamins and minerals apart from some calcium and sodium.

Fortunately, some of the promoters who are selling it on Amazon fill in the blanks by providing a snapshot of the ingredient panel.

It’s also important to be aware there are two versions. One has caffeine. The other does not.

No inclusion rates are provided, but the formulation contains:

  • MCT Powder: Medium chain triglycerides (MCTs) are partially man-made fats. More often than not the ones used in supplements come from coconut and palm kernel oils. Some people use MCTs as performance boosters. Others use them to help with fat burning and increase muscle mass. [SOURCE]
  • Stevia: A sugar alternative that’s often added to low-calorie drinks.
  • Beta-Hydroxybutyrate: A metabolite that carries energy from adipcytes to the peripheral tissues during periods of fasting or exercise. [SOURCE]
  • Malic Acid: A compound that can be obtained from apples and certain other food. Some people take malic acid in supplement form to try and improve their health. It isn’t likely to encourage ketosis, but it may help deliver an energy boost. [SOURCE]
  • Caffeine (original version only): Caffeine won’t cause ketosis, but it’s good for boosting energy and mental focus. In addition to this, it ‘s also a thermogenic fat burner. [SOURCE]

Usage Instructions

To make the drink, dissolve the contents of a sachet in 12-16 oz of cold water by shaking it or stirring vigorously.

The “therapeutic dose” is one sachet per day. People who are using the product to optimize their performance are told to take two sachets per day—one in the morning and one at night.

The product can be taken with or without food.

Pruvit Keto OS Customer Feedback

Pruvit Keto OS customer reviews are predominantly bad, but some people are saying it works.

Of course, there’s a good chance these people are Pruvit promoters. Whenever MLM is involved, there is a risk of fake reviews and other kinds of feedback manipulation.

However, a few good reviews read:

“This changed my life. I feel like I’m thinking clearly for the first time in years and have a lot of energy now. I sleep sound as a baby and my hunger is under control.”

“It works. I lost 8 pounds in the first 7 days. If you want to lose fat, get more energy, and sleep like a baby you have to try it.”

“Great product. Within 30 minutes of taking it I was in ketosis. Gives me lots of energy too and I sleep like a baby.”

And here’s a few that are not so good:

“This is nasty stuff. It tastes vile and made me throw up. I expected more from such an expensive product. What a disappointment!”

“Don’t work. All it did was give me a banging head and a dose of diarrhea.”

“The first thing I have to tell you is this tastes truly awful in a chemically kind of way. The second thing is it don’t work. I gave it a good go and took it for a month. Nothing. Zilch.”

Pruvit Keto OS Side Effects and Health Issues

A lot of customers say the formulation causes headaches.

Other reported side effects include:

  • Stomach ache
  • Nausea/vomiting
  • Sugar cravings
  • Aching sensation in the muscles
  • Increased need for the bathroom
  • Jitters
  • Energy crash
  • Joint pains
  • Racing heartbeat
  • Feeling unwell

That fact that so many people are reporting bad experiences with this product is alarming. Nobody should consider using Pruvit Keto OS unless their doctor has told them it is safe to do so.

Where to Buy Pruvit Keto OS

Although it’s possible to buy Keto OS directly from the Pruvit website it can be difficult to do.

Unless you have been referred to the site by a promoter and can supply his /her referrer code, you will be unable to complete the checkout process.

Without a promoter’s referrer code, the only other option is to become a promoter yourself.

However, some promoters are selling Pruvit via Amazon. That may be an easier way to buy.

So, how much does Pruvit Keto OS cost? At the time of this review, the company was charging USD $85 for per 15 sachets.

That’s silly money and customers who use two sachets per day will need to spend that much every week.


The Pruvit Keto OS guarantee is very poor, but it’s better than nothing. However, promoters who want a refund have it a lot harder than customers do.

Customers who are not happy with Pruvit Keto OS or any other Pruvit product can return it and get a refund, but it will be minus shipping and handling charges. How much are the handling charges? The company fails to say.

After the 30 days are up, customers cannot claim a refund on any product they’ve opened, but they can get a refund for unused product that is still in a sellable condition.

Promoters who are not satisfied with a product can also get a refund if they return the product within 30 days.

Again, any money refunded will be less shipping and handling, but there’s a kicker.

Pruvit will also suspend the promoter account for six months.

If the promoter is returning products his customers did not like, this slap on the wrists is going to be more like a kick in the pants.

After the 30 days have passed, like customers, promoters can only get a refund for unused products. However, in their case, they will only get 70 percent of their money back.


The ingredients used in Pruvit Keto OS “may” allow the formulation to do some of the things Pruvit say it may do, but the benefits are unlikely to be due to ketosis.

However, unless the formulation provides a sufficient amount of the right ingredients it won’t do a thing and, let’s not forget, no inclusion rates are available.

Certainly, customer reviews fail to suggest a resounding success rate and the fact that side effects appear to be an issue for so many people makes it an even less attractive option.

As for the price, it’s a joke. All of the top-rated weight management products are much cheaper to buy and use. They also have longer money back guarantees.
