Many Pruvit Keto OS testimonials circulating online give contrasting and confusing claims about Pruvit’s line of ketone supplements.

Some reviewers claim that the keto OS product line has nothing good to offer, but in the end, endorse other ketone products from manufacturers they are affiliated with.

We are here to give you impartial and clear understanding on how these products can benefit you. We know how excited or suspicious you can be when you hear brand-new supplements that promise overall wellness by enhancing your athletic performance, weight loss, and raising testosterone levels.

Pruvit, however, isn’t keen on saying that their ketone supplements bring about all of the above mentioned health benefits. It is only fitting to make a review that doesn’t claim more or less than what the products can actually offer.

About Pruvit

Pruvit is a relatively new company to the supplement market. However, the company is regarded as one of the pioneers in the field of ketone products and technology.

Unlike other manufacturers, the people behind Pruvit aren’t afraid to show their face in public.

On their official website, you can find videos of founder Brian Underwood and the company representatives detailing their story, mission, vision and brand. You can also find plenty of customer testimonials.

The company name Pruvit is derived from the phrase “prove it” and the company claims that they chose the name because their goal is to prove that helping your body achieve ketosis has many health benefits.

What Is Ketosis?

If you are under a state of ketosis, your body starts to use stored fat for energy, allowing you to easier lose stubborn fat such as belly fat. In ketosis, these fats are converted into ketones when there is little glucose to fuel the body.

The ketogenic diet helps you lose weight and reduce your blood sugar levels by putting you into a state of ketosis (burning fat for energy).

Pruvit Keto OS Overview

Keto OS, short for Keto//Operating System, is Pruvit’s line of ketone powder supplements and main offering.

The three products under the Keto OS brand are:

  • Keto//OS 2.1 Orange Dream​
  • Keto//OS 3.0 Chocolate Swirl
  • Keto//OS Bio Max – Maui Punch

Pruvit also offers Keto Kreme, which is not a supplement that contains pure ketones. Keto Kreme is a low carb coffee creamer to add to your coffee. It contains MCT oil which the liver more readily converts into ketones in the body, so it is still a beneficial supplement for the ketogenic diet and to promote ketosis.

In many reviews, keto os before and after pictures are usually the center of attention. But in our breakdown, we’ll weigh in not just the keto os results in terms of pictures, but also the following:

Keto//OS 2.1 Orange Dream

These ketone supplements come with a citrusy and creamy flavor.

Ingredients​

With pruvit keto os 2.1 Orange Dream, you can choose between caffeinated and decaffeinated versions.

The only difference between the two versions is the presence of caffeine. They both share the same set of ingredients which include:​

  • MCT Powder
  • Beta Hydroxybutyrate
  • Ascorbic Acid
  • Malic Acid
  • Natural Flavor
  • Stevia
  • Milk Ingredients

Both versions don’t contain gluten as well.

The charged version is a good alternative to coffee whenever you need the “kick” to help you wake up or stay awake. However, it isn’t advisable to consume this before you sleep.

The decaf version is for those who are not into caffeinated drinks like coffee and hot chocolate. However, the charged version helps you get into a state of ketosis faster than decaf.​

Preparation​

Are you ready to learn how to take keto os supplements? It’s simple.

To prepare this drink, you need to pour the content of one pack or one scoop into 12 to 16 ounces of cold water. Stir or shake until the powder dissolves.

You can consume the drink with or without eating any solid food.​

Taste​

As to the taste of orange, some may love it while others may not. It is just a matter of personal preference.

Possible Side Effect​s

For the first few days, you might feel some stomach discomfort. To prevent this, use only half a pack or half a scoop for the first few days until your body has finally adapted to the change.

It is beneficial to consume one pack or one scoop a day. For faster results, it is advisable to drink one serving in the morning and one in the evening.​

Packaging​

Keto/OS 2.1 Orange Dream comes in either a canister or single serving pack (also referred to as on-the-go/OTG).

The canister version comes with a scoop and enough for 30 servings. This is a good option if you want to share with a family member or roommate.

The OTG version comes with 30 packs that you can easily carry around. It is suitable for those who travel a lot but want to stay in ketosis.​

Benefits​

The medium chain triglyceride (MCT) and Beta Hydroxybutyrate content are responsible for putting the body into a state of ketosis.

The Beta Hydroxybutyrate content supplies the so-called ketone bodies, or simply ketones. In contrast, the MCT content gets converted into ketones by the liver.​

These ketones serve as a energy source for the body instead of the glucose that is usually supplied by carbohydrates. You are in a state of ketosis when this happens.

When the ketones reach your brain cells and become their main energy source, they may bring about a neuroprotective effect, helping you get rid of brain fog.​

Keto OS Chocolate Swirl is a good option for those who don’t like the fruity taste of Keto OS Orange Dream.

This flavored keto os supplement captures the ideal blend of sweetness and bitterness of chocolate.

coolimagecoolimagecoolimage Keto OS 3.0 Chocolate Swirl

Ingredients​

Just like Pruvit Keto OS 2.1 Orange Dream, Keto-OS 3.0 Chocolate Swirl has charged and caffeine-free versions. They also have the same ingredients except for the added caffeine in the charged version.

The Pruvit ingredients for Keto//OS Chocolate Swirl are:

  • Beta Hydroxybutyrate
  • Acids (L-arginine, L-leucine, L-taurine, L-tyrosine)
  • Ascorbic Acid
  • Butyrate
  • Stevia
  • Inulin (Chicory Root)
  • Potassium Citrate
  • Natural Flavors

Both versions are gluten-free and dairy-free which make them ideal options for vegans.

Preparation​

The preparation is similar to that of Orange Dream.

Taste​

Since it’s a chocolate-flavored powder supplement, you can even add this as an ingredient in your favorite low-carb desserts.

This ketone supplement tastes like candy, which makes it a pleasure to consume.

Possible Side Effect​

Keto OS Chocolate Swirl contains prebiotics that help prevent or manage the stomach discomfort sometimes associated with Orange Dream intake.

Packaging​

Keto OS Chocolate Swirl comes in OTG packs and canisters just like the Keto OS Orange Dream.

Benefits​

The Beta Hydroxybutyrate in this Pruvit supplement is also responsible for putting your body in ketosis so you may experience the following benefits:

  • Weight Loss
  • Mental Clarity
  • Effortless Fasting

Keto OS Orange Dream works faster than Chocolate Swirl though. That is because the former contains more ketones compared to the latter.

But then again, Keto OS Chocolate Swirl has amino acids which also act as energy sources when glucose and ketones in the body are not enough. Amino acids are also beneficial to prevent muscle breakdown when you do resistance training during ketosis.

The body gets its amino acids needs from muscles when glucose and ketone levels are low. Hence, if you are working on building muscle mass, this Pruvit ketone operating system will be your best option to avoid losing muscle mass.

Aside from preventing stomachaches, the prebiotic content in this ketone supplement also strengthens the good bacteria in your stomach. This helps them fight the bad bacteria that can bring an array of issues with your gut and lead to other health problems.

coolimagecoolimagecoolimageKeto OS Bio Max – Maui Punch

Pruvit dubs Keto OS Bio Max as its most advanced product under the OS brand.

Ingredients​

This is also available in charged and caffeine-free versions. Except for the caffeine content in charged versions, both have the same ingredients composed of:

  • Beta Hydroxybutyrate
  • L-Taurine
  • Fermented L-Leucine
  • Erythritol
  • Citric Acid
  • Malic Acid
  • Stevia
  • Xanthan Gum
  • Natural Flavor

The caffeine content in the charged version is similar to the content in a cup of coffee. For your morning or post lunch caffeine kick, you might want to skip the coffee and go for a Keto OS Bio Max instead.

This ketone supplement is also an attractive option for vegans because it doesn’t contain any gluten or dairy. Both versions also lack artificial sweeteners, flavors and sugars.

Preparation​

Basic preparation is the same with that of Orange Dream and Chocolate Swirl.

Taste​

Keto OS Bio Max has a refreshing taste similar to beach-side drinks common in Pacific Islands such as Hawaii.

Possible Side Effect​s

Some people might experience low energy after a few days of drinking this supplement. However, this has not to do with the supplement in itself.

Keto OS Bio Max contains ingredients that suppress your hunger. Your lack of appetite may be because you forget to eat enough calories and that is the reason for the low energy you may experience.

To prevent this, you just need to make sure you still eat even when you don’t feel hungry at all. If weight loss is your end goal, then this effect is rather beneficial.

Packaging​

Keto OS Bio Max is only available in OTG packs with 20 servings.

Benefits​

Weight loss is the main benefit you can get from Keto OS Bio Max. It helps in weight loss in two ways:

  • By providing pure therapeutic ketones that put your body in a fat burning state (ketosis)
  • By suppressing your appetite

coolimagecoolimagecoolimageKeto Kreme

As stated earlier, Keto Kreme is more of a coffee creamer than a ketone supplement. If you are on a budget, this is the cheapest Pruvit product that can still have beneficial effects if you are following a ketogenic diet. However if you are not, then stick to the ketone supplements.

Ingredients​

Pruvit’s creamer only has five ingredients and these are:

  • MCT Powder
  • Stevia
  • Ceylon Cinnamon
  • Coconut Shortening Powder
  • Milk Powder

It doesn’t contain any gluten.

Preparation​

It only takes 30 seconds to prepare your Keto Kreme drink. Unlike the Keto OS line of supplements, it is recommended to mix the contents of one pack into hot beverages such as coffee or hot chocolate.

For a even tastier drink, you may also add any of the following ingredients into your hot beverage together with Keto Kreme:

  • Organic Cacao
  • Peppermint Extract
  • Sea Salt
  • Almond Extract
  • Organic Vanilla Bean

You can also make frappe, cookies and ice cream with Keto Kreme.

Taste​

Keto Kreme offers a natural creamy taste that makes hot beverages more palatable and nutritious, as well as boosting your levels of ketones (only if you are already following the ketogenic diet).

Possible Side Effect​

In the first few days, your body would need to adjust to the MCT powder, since for some people it can give them stomach discomfort and diarrhea. Start with half dosage and build up to a whole pack.

Packaging​

Keto Kreme is only available in OTG packs but you can choose between 20 and 60 servings.

Benefits​

The MCT oil content in Keto Kreme is the best fat to produce ketones from, however it will only be beneficial if you are already fat adapted.

Ketones are created from MCTs right away by the liver, offering you a fast source of energy and preventing fat from being stored on your body.

If you are on a budget however, the best solution is probably just to get regular MCT oil to use with your drinks. After all, Keto Kreme is just MCT in a fancy package with great flavour.​

Precautions

If you have a health condition that requires you to take medication, you should consult your doctor first before you take any ketone products.

There are plenty of Pruvit Keto OS reviews online claiming a lot of side effects from the use of the products. However, all of the so-called Keto OS dangers out there are actually not life-threatening.​ Ketones is a natural fuel for the body, the general medical community is however not well informed on how they should be used or even what a ketogenic diet is.

The Keto Lifestyle

Once you are cleared of any health condition that may prevent from taking any products from Pruvit, you should now prepare for the keto lifestyle.

Yes, the products are effective but much of the health benefits they offer will go to waste if you stick to a sedentary lifestyle and continue eating a diet full of carbohydrates.

Dominic D’Agostino is one of the top researchers of ketogenic diets.

He is a researcher and faculty member of the University of South Florida, College of Medicine. He has a Ph.D. in Physiology and Neuroscience.

After several studies, Dr. D'Agostino concluded that a ketogenic diet may help in alleviating cancers, type 2 diabetes and other potentially fatal and chronic medical conditions.

The following is an example of the typical ketogenic diet plan and macros:

coolimagecoolimagecoolimagepruvit foods

The Ketogenic Diet

Also referred to as keto diet or just keto, the Ketogenic Diet is a low-carb, moderate-protein and high-fat diet.

It has similarities with the Atkins diet, a more popular low-carb, high-fat diet. Both are consumed for weight loss.

How do you know if you are in a state of ketosis?

You can use ketone urine strips to test whether you are in ketosis or not.​

However, these test strips are not effective in finding out whether you are in ketosis or not after the third month on the ketogenic diet. That is because your body will stop dumping ketones in your urine after a couple of months when you become fully fat adapted.

Aside from help you lose weight, ketogenic diets also helps:​

  • Minimize Your Risk for Heart Disease
  • Improve Your Blood Sugar Levels
  • Enhance Insulin Sensitivity
  • Prevent the Onset or Worsening of Degenerative Diseases, Particularly Alzheimer’s Disease

Lower blood sugar levels also help men maintain higher testosterone levels.

Cutting down on carbs can also make you feel moody in the first few days. That is because you are cutting down on sugars and your body needs a week or two to rebalance it's metabolism.

coolimagecoolimagecoolimageoxygenous ketones

Ketone Products

Keto OS supplements belong to the so-called exogenous ketone supplements. However, supplements are not the only products made for the ketogenic diet that are available.

You can also try high-fat snack bars like those of Adapt.​

Though not intended as ketone products, low-carb coffee creamers are a good addition to your keto lifestyle as well.​

Conclusion

These Pruvit keto OS reviews should help you gain a better understanding of the science behind the health benefits of Pruvit’s products. The secret to it's health benefits is enabling you to easier reach a state of ketosis, the  metabolic state wherein your body utilizes ketones instead of glucose for energy.
