Ketogenic supplements have become very popular today, allowing people to help their body enter Ketosis faster.

Not all of these products are created in the same way and offer the same quality ingredients.

Pruvit KetoOS has become a popular supplement among individuals following a Ketogenic diet, as well as those who simply wants a healthy way to lose weight.

In this post, we’ll look at this supplement and consider whether this product is just another scam or a legit supplement that deliver real, reliable results.

What Is Keto OS?

keto os products

KetoOS, which stands for Ketone Operating System, is a powdered product that is mixed with water.

This product has been designed to provide a way for the user’s body to enter a state of Ketosis, a key factor in the Ketogenic diet.

Ketosis has been associated with a number of great benefits for the user body, with weight loss being at the top of the list.

When the body enters ketosis, carbohydrates are no longer used as the body’s primary source of energy.

Instead, the body turns toward fat as a resource to make energy. This, in turn, means the user is continuously burning fat with all physical exertion.

What makes Pruvit Keto OS such a unique product is that, even though primarily promoted as a product to help better weight loss results, this supplement has been developed to offer a number of additional benefits for the user’s body and their general well-being.

In addition to claiming to help the user experience improvements in their weight loss strategy, this supplement also claims to deliver a wide range of other benefits.

These benefits include enhanced focus and alleviation of brain fog together with a significant boost in energy levels and a reduction in inflammation throughout the body.

The supplement also claims that it will help to improve the user’s mood and even help them sleep better and wake up refreshed.


This supplement has been produced to deliver essential nutrients to the body of the user, as well as high-quality naturally extracted ketone and other herbal extracts that are known to promote better well-being and improved weight loss during a weight management program.

A single serving of the Keto OS supplement provides the user with the following nutritional content:

  • 67% of their daily sodium intake requirement.
  • 14% of their daily potassium intake requirement.
  • 26% of their daily magnesium intake requirement.
  • 33% of their daily calcium intake requirement.

Apart from these essential nutrients, the supplement also includes a range of herbal extracts that we should look at.


This is a beta hydroxy acid that is often considered to be one of the cleanest energy sources that the body can utilize for the production of energy.

This is also supposed to be the critical ingredient of this supplement, aiding in increasing the number of ketones in the user’s body and, in turn, helping their body turn to fat for energy.

One study explains that beta-hydroxybutyrate may hold benefits for improving certain metabolic diseases, such as type 2 diabetes.

Amino Acid Complex

Amino acids are the broken down form of proteins and play multiple crucial roles in the body.

Specific amino acids are vital for heart health, circulation and even muscle growth.

The amino acid complex contained within this supplement include L-Arginine, L-Taurine, L-Leucine, and L-Tyrosine – all playing a vital part in improving the user’s health and helping them reach their weight loss goals faster.


A natural stimulant that is very popular in modern-day weight loss supplements.

Not only does the inclusion of caffeine promote better energy levels during the day, but it can also help to stimulate the metabolism, which may improve weight loss.


A fiber supplement that is found in thousands of different plants.

The supplement does not specifically state from which plant the inulin contained in their powdered drinks are extracted, however.

Inulin is often considered a prebiotic fiber supplement and has been linked to numerous benefits, including improvements in metabolism and an increase in energy levels.

Other Ingredients

Other ingredients that are also found in this product include stevia, ascorbic acid, potassium citrate, and butyrate. The flavoring of the supplement is produced through natural flavoring agents.

It should be noted that some of the KetoOS products contain dairy and is not vegan-friendly.

This accounts for the orange flavor option.

The other two flavors, including chocolate swirl that the supplement is presented in, does not contain any dairy and is perfect for individuals following a vegan lifestyle.

How Does This Product Work?

keto os results

The primary function of the Pruvit KetoOS supplement is to provide the user’s body with pure, high-quality, all-natural ketones.

Ketones are naturally produced in the body when there is a limited supply of carbohydrates available.

Carbohydrates are usually the main compound that the body turns to in order to produce energy.

When carbohydrate levels decline, the body starts to look for an alternative energy source.

The body finds fat as an alternative product to use for energy.

The liver then breaks fat down into smaller particles that can be used to produce energy – these smaller particles are called ketones.

Once the liver starts to produce ketones, a person goes into a state called “Ketosis.”

The problem, however, is that it can take quite some time for the body to enter this state and Ketosis can cause some unpleasant symptoms during the first few days (sometimes for weeks).

The purpose of the ketones found in this supplement is to help speed up the process of entering Ketosis among individuals who do wish to adopt a Ketogenic diet.

Additionally, the product also provides the body with ketones that can then be used to boost energy and metabolism, and help to promote better weight loss, in users who want to take advantage of ketones, but without having to start following a Ketogenic diet.

How To Use It?

This product is very easy to use.

To use the product, the user simply needs to combine a single heaped scoop of the powder with a glass of cold water.

They will need to ensure they shake the container vigorously or stir thoroughly to ensure the powder properly mixes with the water content in the container or glass they are using to mix their supplement.

The daily dosage of the product varies from one user to the next.

For therapeutic use and the general maintenance of a healthier lifestyle, the manufacturer of the product recommends taking a single dose (one scoop) of the product daily.

Individuals who would like to experience more benefits, get their body into Ketosis faster or use the supplement for a significant improvement in their overall performance are advised to take two servings of the product each day.

The first serving should be taken in the morning and the next one either in the afternoon or at night.

Side Effects

side effects

This is an all-natural product that utilizes naturally-occurring substances to help the user experience a wide range of benefits.

The supplement contains ingredients that the body already needs on a daily basis, which means there are little risks of side-effects associated with the use of this product.

Individuals who will be utilizing Pruvit Keto OS to help them enter Ketosis should note that they will still most likely experience the particular symptoms associated with the body entering this state.

These symptoms may include bad breath, appetite suppression, fatigue and reduced performance.

This is just the body starting to look for an alternative energy source, and the symptoms tend to resolve once the body starts to turn to fat for energy – the use of this supplement may actually ease these symptoms.

Pros & Cons


  • Unlike products that contain Raspberry ketones, which often confuse customers and make them think that they are buying a product that contains actual ketones, this supplement contains actual ketone extracts. This means that, with the frequent use of KetoOS, the user can put their body into Ketosis faster and experience the various benefits of using fat as an energy reserve instead of carbohydrates.
  • While the brand primarily specializes in selling a large variety of health and weight loss supplements, they also offer their customer useful advice tips and even blog posts to help them succeed in reaching their goals. The brand also has a web page dedicated to helping the user get their body into Ketosis with the use of their supplements, along with some simple lifestyle modifications.
  • There are many people who have used the KetoOS supplements before and have experienced impressive results. The before and after photos of these users can be found both on the official web page that represents this product, as well as on various external websites and review platforms. This makes it easy for the interested individual to determine the effectiveness of this supplement.


  • The manufacturer of this brand only provides their products to a selected number of countries. While they are still expanding to new areas, individuals interested in using their products need to ensure they live in one of the currently supported countries, or they will not be able to buy any of these products. The product is currently only available in seven countries, which means they still have quite a long way to go.
  • While two of the flavors that the KetoOS mix comes in are dairy free and appropriate for vegans, the orange fruit flavored option does contain dairy and is also not vegan-friendly. This means that vegans will not be able to opt for this flavor and will have a more limited number of options to choose from.
  • The supplement contains Anhydrous Caffeine, which is a stimulant. While associated with a number of potential health benefits, many people experience sensitive reactions when they take any type of supplements that contain a stimulant. Thus, users who are sensitive to caffeine and stimulants, in general, may not respond well to this product.
  • The KetoOS supplement, along with the other supplements and products manufactured by this brand, is quite expensive – even when compared to some of the similar ketogenic supplements that are currently available.

Final Verdict

final verdict

Ketosis, a state where the body starts to utilize fats for the production of energy instead of carbohydrates, has been proven beneficial for weight loss and possess other potential health benefits.

Entering this state can be difficult, which is why many people turn to supplements to help speed up the process.

While many products on the market use the term “ketones”, very few of these actually include the right compounds to help the body enter a mode of ketosis.

KetoOS seems to be one of the few options that include the right type of ingredients to promote Ketosis and help the body start to burn fat instead of carbohydrates in order to produce energy.

The brand has expanded to a number of countries already, and a significant amount of positive reviews can be found on the internet related to the effectiveness of this particular product, as well as other products manufactured by the brand.
