Our Verdict: Yes, it did for me. Prüvit Ketones is a beneficial supplement for people switching to the keto diet. I find that keto can be a very restrictive eating plan, but Prüvit Ketones helped me maintain my progress.

Do Prüvit Ketones Work? 4

We also feel that Prüvit Ketones might help enhance overall health. It's because it has essential minerals, amino acids, and botanical ingredients.

But the supplement won’t magically cause you to lose weight. If you're not planning to follow a ketogenic diet, you won’t be able to maximize its benefits.

In my experience, Prüvit’s ketone supplement was useful for avoiding the dreaded keto flu. Keto flu is one of the drawbacks of the ketogenic diet.

It happens quickly after beginning a ketogenic diet. It includes symptoms like fatigue, headache, nausea, and brain fog.

Prüvit also helped lessen my energy slumps. And it made it easier to maintain a prolonged fast while on the keto diet.

What Is Prüvit Ketones?

Prüvit Ketones is a supplement that provides a readily available source of ketones. It benefits those looking to start a ketogenic diet or anyone already on the keto diet.

The keto diet or ketogenic diet is a low-carb, high-fat, moderate-protein eating plan. It gained popularity due to significant weight loss results many people, including myself, have experienced.

However, it also comes with challenges due to its restrictive nature, leading some people to fall off the wagon. The keto diet limits your carb intake to 20 to 50 grams daily.1

Some people need help eliminating so many carb-heavy foods from their diets. Imagine removing staples like rice, bread, and starchy vegetables like potatoes.

Here’s where Prüvit Ketones come into play. But first, let’s talk about what ketones are.

The body produces ketones, or ketone bodies, when its primary fuel source, glucose, is depleted.2 During the state of glucose depletion, the body turns to fat as its source. This forms ketones as its by-product.

The restrictions in a keto diet encourage ketone production. It limits your carb intake, which is the primary source of glucose.

With the help of Prüvit Ketones, your body can enter a ketosis state without going through extreme measures, such as starvation or prolonged fasting.

Understanding Exogenous Ketones

Ketosis is a metabolic state in which your liver turns to fats for energy instead of carbs. During ketosis, your liver burns your fat stores and converts them into ketones, which become your primary energy source instead of glucose.

Ketones have two types: endogenous and exogenous ketones.

  • Endogenous ketones are the ones your body produces naturally through the ketosis state.
  • Exogenous ketones, on the other hand, are the ketones your body gets from external sources, like supplements. They usually come in the form of ketone salt, which is the main active ingredient in Prüvit ketones.

To better understand the difference between endogenous and exogenous ketones, you can think of it as making coffee at home versus buying it from a cafe.

Endogenous ketones are like brewing your coffee at home; your body does all the work and produces its ketones.

On the other hand, exogenous ketones are like buying coffee from a shop; they provide ready-made, instant external energy.

Supplements that supply ketones appeal to people who are put off by the weeks-long commitment required by the Ketogenic diet to achieve ketosis.

Do Prüvit Ketones Work? 5

Exogenous ketones can raise ketone levels almost instantaneously, even if you aren’t in ketosis before taking them.

In low-carb diets like the keto diet, your body doesn’t use glucose as your primary energy source.

Glucose comes from carbs and becomes the usual energy source when you’re on a regular  diet. The body stores it in the liver and muscles as glycogen.

When you switch to keto, your glycogen stores start to curb. This triggers your body to enter a ketosis state. But the process usually takes weeks.

Exogenous ketones can help boost your body’s ketone production and expedite ketosis. They can also aid in weight loss, improving your energy and focus.

Prüvit Keto//OS NAT

Prüvit developed an exogenous ketone supplement called Prüvit Keto//OS NAT®. Interestingly, they created it through a natural fermentation process.

When compared to our bodies' natural ketones, Prüvit claims that these Pure Therapeutic Ketones® are remarkably similar.

The critical ingredient in Prüvit Keto//OS Nat is KetoNAT™, made with R-Beta Hydroxybutyrate (R-BHB).

It’s a type of ketone body that your liver forms from fatty acids. Think of (R-BHB) as a delivery truck—it transports energy from the liver to the rest of your body.

Apart from KetoNAT™, Prüvit Keto//OS Nat also includes:

  • B6 and B12
  • Calcium
  • Magnesium
  • Sodium
  • N8 Max NAT™ Blend: Prüvit’s proprietary blend that contains L-Taurine, Fermented L-Leucine, and C-Med 100® or the inner bark of Cat’s Claw (Uncaria tomentosa)

The R-BHB in Prüvit Keto//OS Nat is attached to sodium, calcium, and magnesium. Scientists refer to this mixture of minerals and R-BHB as ketone salts.

Prüvit is confident that drinking Keto//OS Nat twice a day will help you lose weight and enjoy other benefits, like boosted energy levels.

Prüvit ensures that their supplements help your body enter a ketosis state while promising results in energy boosting, immune function, focus, and fat loss.

How Long Does Prüvit Take to Work?

Prüvit claims that their ketone supplements can take effect within 60 minutes of consumption. This means it can make you reach nutritional ketosis within an hour of taking Prüvit ketones.

You might be interested in this alternative if you're like me and the thought of waiting weeks to achieve ketosis through a ketogenic diet sounds off-putting.

Companies like Prüvit have developed exogenous ketones to help you achieve ketosis and reap its benefits while skipping extreme measures, like strict fasting or carb elimination diets.

Exogenous ketone supplements can quickly increase your blood ketone levels.

Experiencing the Prüvit 10-Day Challenge

The Prüvit 10-day challenge is not a diet regimen. You won’t need to do macro-counting, complex grocery lists, or intricate meal plans.

Prüvit is simply raising a challenge to dieters to try Prüvit ketones for 10 days and experience how it feels to run on a premium fuel source.

Do Prüvit Ketones Work? 6

Anyone new to the Prüvit community can start with the 10-Day Drink Ketones Challenge to get a taste of the benefits of Pure Therapeutic Ketones®.

In the past, I’ve tried doing the keto diet. Despite the struggles, I can proudly say I succeeded in following it. However, I often wonder if there is an easier way to achieve ketosis.

That’s when I came across Prüvit Ketones. Prüvit claimed it’s possible to do a keto diet without counting too many carbs. This claim piqued my interest.

Intrigued, I decided to give the 10-day challenge a try to kickstart my comeback to the keto diet.

The first effect I noticed was a huge increase in my energy levels after consuming three packets of Prüvit Ketones. Because of this, I experience less post-lunch plunge.

In addition, Prüvit Ketones helped curb my appetite. I felt full for longer periods, causing me to eat smaller portions than usual.

What are the Benefits of Prüvit Ketones?

Prüvit Ketones offer a natural way to expedite achieving a ketosis metabolic state, leading to weight loss.

But besides that, they can also help you enhance your energy levels and mental sharpness.

Weight Loss and Ketosis

Prüvit Ketones help your body achieve a ketosis state. Prüvit emphasized that they designed their supplements to help boost your body’s natural ketone supply.

Why is this significant? When your body is in ketosis, it starts to rely on fat for energy instead of carbs. This change causes your body to burn fat faster, resulting in a shift in your metabolism.3

Research shows that people in a ketosis state burn an average of about 300 additional calories every day. This can potentially lead to weight loss over time.4

However, you should also change how you eat to achieve weight loss. Prüvit Ketones isn’t some sort of magic drink that can help you lose weight while staying on a poor diet.

By using Prüvit Ketones to achieve a state of ketosis or to boost your body’s ketone production, you could be taking a big leap towards your weight loss goals.

Improved Energy Levels

Prüvit Ketones highlighted that their ketone supplements can improve your energy levels by boosting your body’s ketone production.

Many studies suggest that ketones can be a more efficient fuel source than glucose.5,6

Studies indicate that the body uses ketones better than glucose for energy. Ketones are advantageous over glucose because the mitochondria, or the cell's powerhouse, can use them directly.7

On the other hand, the cells must first transform glucose into pyruvate before the mitochondria can use it. The process can be inefficient and produce waste products.7

Research suggests that ketones contain more energy per unit of oxygen used in metabolism. Compared to glucose, ketones are more effective at converting oxygen into adenosine triphosphate (ATP).8

ATP is the main energy currency of the cells. The concept of ATP can be likened to storing money in a bank, except that your cells use it to store energy.

The body’s main source of energy is glucose. However, the body can only keep them in limited quantities.

Have you ever experienced energy spikes and crashes throughout the day? That's due to the fluctuating blood glucose levels in your body.

On the other hand, ketones are more stable and provide a more sustained release of energy.

Taking Prüvit Ketones can increase the ketones in your body and put you in a state of nutritional ketosis. It might cause your body to start burning fat for ketone bodies.

The KetoNAT™ formula has a more bioavailable R-BHB. Your body absorbs it more readily, allowing for a more effective energy boost.

Enhanced Mental Clarity

Prüvit claims that its proprietary blend can help optimize your focus, memory, and cognitive functions.

The N8 Max NAT™ or Prüvit Keto//OS Nat’s unique formulation includes ingredients that promote mental clarity.

  • L-Taurine – Several studies demonstrate that taurine can enhance your memory and learning ability.9 Taurine was shown to activate glial cells, which keep the nerve cells and their surrounding environment healthy.10
  • Cat’s Claw – A study shows that Cat’s Claw plant extract might help to prevent and reduce plaques and tangles in the brain caused by beta-amyloid and tau protein build-up due to aging.11

In addition, Prüvit Ketones' primary content, ketone bodies, are able to cross the blood-brain barrier and function as an alternative fuel for the brain.12

Many studies show that ketones can supply energy to the brain more efficiently on a short-term basis than glucose, providing as much as 70 percent of the brain’s energy needs.13

How Do Prüvit Ketones Taste?

Prüvit Ketones consumers had divided opinions on how the supplements taste. Some said that several flavors have an unpleasant taste.

Meanwhile, others mentioned that the flavors taste fine and even better than protein supplements.

However, I agree with one comment I saw on the internet. I noticed they are sweet with an aftertaste, but nothing I can’t tolerate. This is true for the Prüvit Ketones flavors I’ve tried: Strawberry Peach and Swiss Cacao.

Flavor Options

Prüvit Ketones has many exciting flavors, and choosing which flavor to buy can be difficult. Sometimes, flavors are unavailable from the Pruvit website, but you can read about them elsewhere.

Prüvit Ketones often introduces new flavors as limited-time 'seasonal' offerings, so their availability on the website might change occasionally.

But the current mainstay flavors or the ones always in stock are:

  • Trü Passion – Refreshing passionfruit taste
  • Blueberry Acai – Mild blueberry
  • Strawberry Peach – Light and refreshing strawberry with a hint of peach
  • Raspberry Lemonade – Sweet and crisp raspberry with lemonade
  • Maui Punch – Hawaiian fruit punch (hints of orange, pineapple, passion fruit, guava, and papaya)
  • Lime Time – Smooth and light limeade
  • Splash – Watermelon mixed with grapefruit
  • Heart Tart – Strawberry sweet tarts
  • Swiss Cacao – Sweet hot chocolate or brownie batter
  • Berry Blue – Blueberry slushie

As mentioned, I only got to try Strawberry Peach and Swiss Cacao. I usually start my day with juicy and fruity flavors of Strawberry Peach to get that jolt in the morning. Then, I drink my rich and smooth Swiss Cocoa for my afternoon pick-me-up.

Mixing and Consumption Tips

To make one serving of Pruvit Ketones drink, Pruvit recommends dissolving one packet with 12 to 16 ounces of cold water.

I found that using a shaker bottle works well to mix up your Pruvit Ketones. I also discovered that the powder is less likely to form clumps in the bottom if you add ice, water, and the ketones on top.

You can also enjoy it hot, as I do with the Swiss Cocoa flavor. I prepare it like a typical hot chocolate drink.

Take your time with the ketones. You should consume them for about 30 minutes at an easy pace to allow your body to absorb and benefit from them fully.

Is Prüvit Safe to Use?

Yes, Prüvit Ketones is safe for most people.

There aren’t many long-term (or even short-term) studies on the Prüvit Keto//OS products.

But based on existing research into the ketogenic diet and the other ingredients of Prüvit Keto//OS NAT, we can infer that Prüvit products may be generally safe to consume.

However, ketone supplements may interfere with certain conditions or medications. For instance, they may lower blood sugar levels.

People with type 2 diabetes who are currently on medication to manage blood sugar levels should speak with their doctor before taking ketone supplements.

As a precaution, keep in mind that researchers still have limited information on the long-term effects of ketone supplements.

Talking to a healthcare provider before starting a dietary supplement like exogenous ketone supplements is best.

Potential Side Effects

The company’s website didn’t mention anything about the possible side effects of their products.

However, ketone research suggests that some potential adverse reactions people may experience include the following:

  • Digestive upset, like nausea, vomiting, and diarrhea
  • Jitteriness
  • Sleep problems
  • Dehydration
  • Frequent urination
  • Tiredness
  • Sugar cravings
  • Constipation
  • Muscle cramps
  • Flu-like symptoms
  • Bad breath

These symptoms are common effects of entering the ketosis state when you follow the keto diet.

Keep in mind that these symptoms are temporary. They will disappear within a week or two as your body adjusts to burning fats rather than carbs for energy.

In my experience, increasing my water, fiber, and salt intake helped lessen these side effects when I was just getting started on the keto diet.

Caffeine Content and Sensitivity

Prüvit Keto//OS NAT has two varieties: Charged and Caffeine Free.

The Charged or the caffeinated version has a caffeine content of about 12 to 16 ounces of coffee, but the website didn’t specify the exact amount.

According to the Food and Drug Administration, healthy adults should consume no more than 400 mg of caffeine daily, equivalent to roughly four or five cups of coffee.14

They cited that it’s the amount not typically associated with detrimental effects. However, we vary significantly in sensitivity to caffeine and how quickly our bodies metabolize it.

Health conditions like hypertension and certain medications can intensify the effects of caffeine in some people.

Given the amount of caffeine in Prüvit Ketones, it may not be safe for those with increased sensitivity to caffeine’s effects.

How to Use Prüvit Ketones for Best Results

Prüvit Ketones isn’t some miracle slimming beverage—to achieve your desired results, it’s important to follow the instructions and pair it with a healthier lifestyle.

When and How to Take Prüvit Ketones

Prüvit recommends consuming two packets of Pruvit Keto//OS NAT a day. The company’s website specified the best time to take their supplements.

  • Before 9 AM – Take Charged or the caffeinated variety with your breakfast to enhance your daily performance and focus.
  • During the day – Drink lots of water throughout the day. It's also recommended that you drink half your body weight in water every day to assist in flushing out the minerals in the product.
  • Before 7 PM – Drink the caffeine-free variety to aid sleep and recovery.

Combining Prüvit Ketones with Diet and Exercise

Using Prüvit Ketones to improve your health can be a good choice. However, to maximize the health benefits of Pruvit Ketones, you should pair it with a good diet and regular exercise.

When following a ketogenic diet, engaging in aerobic exercise is more appropriate. Low-intensity, steady-state cardio exercises like yoga and stability training are included in this category.

The body mainly uses fat for fuel during lower-intensity aerobic workouts. You can maximize the weight loss benefits of doing lower-intensity exercise since your body is already fat-adapted while in ketosis.15

If you're using Pruvit Ketones, it's best to stick to a healthy diet low in carbs and high in fats. This is a great way to keep yourself in ketosis and maximize the benefits of Pruvit Ketones.

Where Can I Buy Prüvit Ketones?

If you’d like to purchase your Prüvit Ketones and other Prüvit products, I discovered that you can purchase them directly from their website.

You can also get Pruvit Ketones from retailers like Amazon and eBay. However, you may not be able to get the same discounts if you purchase from these retailers.

Purchasing Options and Experience

You can purchase Prüvit in two ways: one-time or monthly shipping through SmartShip.

However, the website will not let you complete your checkout without entering a referring member’s referrer code. This is because Prüvit is a multi-level marketing (MLM) company.

Fortunately, I knew someone who was a Prüvit distributor, so I just asked for their referrer code to complete my order. Although it was a bit of an inconvenience, I must admit.

How Much Do Prüvit Ketones Cost?

Prüvit Keto OS//NAT costs $138 for a box of 20 on-the-go packets, regardless if you are choosing the caffeinated or caffeine-free variation.

Pricing and Payment Options

Prüvit typically sends out orders within two to four days. However, during their peak seasons, shipping timeframes may change based on the product you order and shipping address.

Their website accepts Mastercard, Visa, and American Express cards for payment.

Prüvit Ketones vs. Competitors

Let’s compare Prüvit Ketones to other exogenous ketone supplement brands and see how they stack up.

Ketone Supplement BrandPriceFlavor optionsTypes of ketone/sIncludes electrolytes
Prüvit Ketones$13812Beta-hydroxybutyrate (BHB)No
Perfect Keto$37.99Three flavors Beta-hydroxybutyrate (BHB)Yes
Real Ketones$59.99Four flavorsBeta-hydroxybutyrate (BHB)Yes

Prüvit Ketones vs. Perfect Keto

Perfect Keto is more affordable, but Prüvit offers more variety in flavors. We find it appealing and know other users would, too, especially those who easily get tired of the same taste daily.

The fact that Pruvit is an MLM company isn't even our biggest complaint. It is that the ingredients list consists of a proprietary blend.

It means you know what you’re getting, just not how much. That includes the ketones it contains.

On the other hand, with Perfect Keto, you'll know precisely how much ketones you are receiving. Plus, it contains electrolytes to help you avoid keto flu and keep you extra hydrated.

Prüvit Ketones has ten seasonal flavors besides the regular ones. On the other hand, Perfect Keto has unflavored capsules in addition to the regular flavors it offers.

Both Prüvit Ketones and Perfect Keto offer one-time purchase prices.

Prüvit Ketones vs. Real Ketones

Another less pricey ketone supplement than Prüvit is Real Ketones. The smaller packs of Real Ketones make them more convenient to carry around and control regarding portions.

Like Perfect Keto, Real Ketones have electrolytes, which Prüvit Ketones doesn’t have. Real Ketones also have medium-chain triglycerides (MCTs).

MCT is a type of healthier dietary fat that helps your body make ketones.

Both Prüvit and Perfect Ketones offer one-time purchase prices.

Is Prüvit Ketones Worth It?

Prüvit Ketones may be worth a try

After almost a month of using it, I can say that the product effectively curbed my appetite and controlled my cravings, especially for sweets.

In addition, I have experienced other benefits like sustained energy levels and improved focus.

Based on my experience, Pruvit Ketones can be a good option for people looking to shed some extra pounds or improve their physical and mental health. 

However, I think it’s wise to consult your doctor before starting any new supplement.

Who Can Benefit from Prüvit Ketones?

Anyone can try Prüvit Ketones, but the people who benefit the most from ketone supplements are those who are:

  • Trying to lose weight
  • Following a ketogenic diet
  • Looking for an energy boost alternative to coffee
  • Aiming to improve their brain functions

Next Steps and Encouragement for Readers

If you do decide to try Prüvit Ketones, start gradually. Observe how your body reacts to a low dose first. Stop using Prüvit Ketones and consult your doctor if you have severe reactions. 

If you use it regularly and consistently and pair it with healthy lifestyle choices, you might start to see improvements quickly.
