On the keto diet? You’re one of many.

The low-carb, high-fat ketogenic diet has become a staple for fitness fanatics to keep their weight in check, and for people with complex conditions like diabetes and epilepsy to control their symptoms. This wonder-diet promises a lot – but should be attempted with caution.

Cutting out food groups should ideally be done gradually under the watch of a doctor. But, since many people can’t afford to do this, plenty of brands have released supplements to help with the transition.

Enter Pruvit and its health-boosting keto supplements.

Texas-based Pruvit’s keto weight-loss products have been a hit with consumers. Their website states that they aim to be the “worldwide leader in keto technology” – but what is this?

Pruvit’s Keto OS NAT is the newest keto supplement in the company’s line. The reports indicate this stuff works like a “keto technology.” The supplement is engineered to speed up the production of ketones in the body to enhance the metabolism and burn fat faster.

Pruvit users overwhelmingly give the company’s dietary supplements positive reviews. The most common feedback is that the products are simple but effective – perfect for those with busy lifestyles looking to transition into ketosis quickly and easily.

With such a buzz around them, any new ketone supplement produced by Pruvit is worth a serious look.

To understand how their latest product works, and if it’s worth it, let’s take a deep dive into Pruvit NAT.

What Is Pruvit Keto OS NAT?

Pruvit Keto OS NAT

Keto OS NAT is similar to many other keto supplements. It comes in powder form and is recommended to be taken twice a day.

However, its main difference is that it claims to be more effective at producing ketones in your system than its competitors.

A key aspect of the product’s effectiveness for weight loss comes from its appetite-suppressing properties. It makes you less hungry and therefore less likely to snack between (ketogenically-balanced) meals.

The new Pruvit supplement provides your body with exogenous ketones. These are identical to the endogenous ketones created by your own body when it goes into ketosis. Ketones allow your body to metabolize fat into energy.

The result? You shed weight faster than many other alternatives.


What Are Ketones?

Ketones are an organic compound produced as a byproduct of fat metabolism.

Typically, your body uses glucose as its main source of energy. When you deprive your body of natural and manufactured sugar, it switches instead to burning fat.

Fat-burning is what allows you to stay energized, as this process creates ketones. This is the body’s alternate energy source when glucose is unavailable.

Your body naturally produces ketones during times of starvation, prolonged fasting, or ketogenic dieting. The switch from burning sugar to fat is known as going “into ketosis” and is a very effective way to burn fat.

In ketosis, your liver takes fatty acids and transforms them into ketones. Your body utilizes these ketones for its energy sources.

Lunch and dinner meal

The liver produces three ketones during the process: acetone, beta-hydroxybutyrate, and acetoacetate. Tissues, such as muscle tissue and your brain, and other bodily systems use these compounds as their main energy source.

There are two types of ketones that your body can produce:

  • Endogenous ketones: These ketones come about during the natural process of ketosis.
  • Exogenous ketones: These ketones are supplied to the body through external sources such as Pruvit NAT.

Most of the exogenous ketones produced by supplements utilize beta-hydroxybutyrate as their ketone source. The same is true for Keto OS NAT.

Since the purpose of the keto diet is to burn as much fat as possible [1], you want to produce as many ketones as possible to use them as energy. Pruvit’s new Keto OS supplies these ketones exogenously, giving you an energy boost without the need to eat carbohydrates.

Pruvit Nat: A Solution to the Ketogenic Diet?

Pruvit’s NAT supplement is intended to be used in combination with a ketogenic diet. The meal plans on this diet are based on extremely low carb consumption and a high-fat percentage.

However, adhering to the diet is tough for many people – this is where Pruvit comes into play.

The hardest part of maintaining ketosis is the radical change in diet. With other diets, slipping up and eating potato chips isn’t the end of the world. However, eating more than the recommended amount of carbohydrates will “knock your body out of” ketosis.

If you enjoy eating a variety of foods and cuisines, the ketogenic diet can be frustrating. In this way, Pruvit isn’t a solution, but an aid to ensure you get enough energy from your new diet.

Getting enough energy can be extremely hard in the initial stages of ketosis. Many people feel sluggish, get headaches, and suffer from “keto flu”. That’s why energy supplements like Pruvit Keto are important.

With Pruvit Keto, people eating a keto diet for weight loss can stay within ketosis while still having enough energy to work out. Therefore, using this product helps you lose weight faster.

Keto OS NAT Claims

The most prominent claim that the Keto OS NAT makes is that it gives your body natural, exogenous ketones. These absorb quickly, helping your body go into ketosis faster.

The company also claims that their supplements help:

  • Activate cellular DNA repair
  • Balance amino acids
  • Support cell enzyme function
  • Boost immune system

All these effects help your body to perform at its optimal level. If you’re ready to equip your body and make it a powerhouse of energy and fat-burning, check out Keto NAT now!

What Are the Ingredients?

Keto OS NAT is gluten-free and vegan. It contains no sugar or alcohol. The product uses R-Beta Hydroxybutyrate that is water-soluble to get ketones into your system.

Here are the ingredients in Pruvit’s newest supplement:

  • BHB (R-Beta Hydroxtbutyrate; also simplified to BHB). BHB helps regulate your blood’s ketone levels. It is an organic compound that is essential to the process of metabolizing fat.
  • L-Taurine. This is a crucial component of protein production. L-Taurine is an amino acid utilized by the body to create muscle tissue. In the scheme of losing weight, this compound makes your exercise more effective.
  • Fermented L-Leucine. Another amino acid, L-Leucine is not produced by the body. Instead, it must be consumed. This amino acid plays a key role in helping to build muscle.
  • C-Med 100. C-Med 100 is a compound known to effectively counteract leukopenia, a condition that makes your body unable to produce an adequate number of white blood cells. It also aids in DNA repair. The reason for its inclusion in Keto NAT is unclear. One possibility is that it’s there as a precaution, as there has been a study that shows ketosis can aggravate neurodegeneration. C-Med 100 would help prevent this if true.
  • Erythritol. An additive used to improve taste, erythritol is a natural sweetener [2]. It’s known to have basically no calories and zero glycemic index.
  • Rebaudioside A. Rebaudioside A is another sweetener that is derived from Stevia. It’s supposed to be about 200 times sweeter than sugar and makes consuming Pruvit’s NAT more palatable.
  • Caffeine. The enhanced versions of the supplement give users a natural energy boost to aid with powering through workouts and work days.

The product also contains minimal amounts of calcium, vitamin B12, and beta-carotene. These are helpful vitamins for bodily functions.


What Are the Different Flavors?

Keto OS NAT all flavors

The new Pruvit NAT supplement comes in a variety of flavors including:

  • Raspberry Lemonade
  • Swiss Cacao
  • Maui Punch
  • Chocolate Swirl
  • Orange Dream (contains dairy)

All flavors are vegan and dairy-free except for Orange Dream.

The flavors offered are sold “as-is” or “charged.” The “charged” version contains additional caffeine. Those following a keto diet may find this appealing as the extra energy boost can aid users in their workout efforts.

How Does It Work Exactly?

The process of ketosis brought on by the Keto OS NAT system depends upon the presence of BHB salt. The exogenous ketone allows your body to metabolize fat into energy in the absence of carbohydrates. It’s also the most abundant kind of ketone your body creates when in the state of ketosis.

The water-soluble ketones employed by Keto NAT allows them to take effect in your body within an hour. They raise ketone levels, so you can lose weight more easily.

Besides an accelerated process of reaching ketosis, Pruvit NAT provides other benefits.

Slipping into ketosis quickly, with energy supplements, will help prevent keto flu. Keto produces flu-like symptoms related to a lack of energy and a sudden change in diet and nutrients, making it hard for people to stick with their nutritional plan and fitness goals.

Since Keto OS NAT helps the body to quickly absorb BHB, it helps people avoid some of the drawbacks associated with the ketogenic diet.

What Are Keto OS NAT Benefits?

Besides helping users quickly and effectively lose weight, Keto OS Nat provides other benefits thanks to the BHB in its ingredients. These include:

  • Preventing disease
  • Enhancing cognitive function
  • Preventing oxidative damage to the heart
  • Reducing inflammation
  • Stabilizing blood glucose
  • And more

Put simply, BHBs help you achieve and stay in the best health possible even as your body moves from burning carbs to fats.

How Much Does Keto OS NAT Cost?

Pruvit NAT can be found on their website for 20 servings at 130 USD. The company also offers samples for a price range of 25 to 60 USD.

Many other Keto OS NAT reviews fail to mention the sale of the supplement on Amazon. You can purchase 20 servings on the site for 116 USD.

Potential Keto OS NAT Side Effects

If you’re new to the ketogenic diet, you should educate yourself on all potential risks and side effects.

Trial users of the beta version reported side effects similar to other diet supplements and some energy drinks.

The side effects that you may experience can include the following:

  • Fatigue
  • Nausea
  • Headaches
  • Stomach rumbling
  • Jitters while using the “charged” or caffeinated versions

However, many of these effects can be eased by eating more (according to foods on your diet plan).

When it comes to these two supplements, there’s no difference at first glance. You have to compare the two by looking at the BHB composition.

With the Keto OS NAT, one of its main appeals is the speed of the process. The fermented BHB ketones absorb into the body quickly.

On the other hand, Keto OS Max helps you work out longer. It also gives you more focus because it contains more amino acid chains. There’s reportedly less chance of feeling fatigued with the Keto OS Max.
