KETO//OS NAT Review – A Few Things You Should Know Before You Try It

KETO__OS NAT Review

Prüvit is pulling out all the stops in the latest product from their KETO//OS line, but is it really as good as they say it is?

The ketogenic diet can be a difficult path to tread and if you really want to follow it, you’re going to need all the help you can get.

All About Keto

Out of all the recent fitness and weight loss trends, the keto diet has received the most attention by far. It is a diet variation that involves eating significantly fewer carbohydrates while eating more fat and protein.

The goal of the keto diet is to ultimately have your body reach the state of Ketosis, a metabolic state where the body uses fat as a fuel source instead of carbs or proteins.

ketogenic diet

Yes, the high fat and protein intake may seem counter-productive, but the diet causes the body to convert fat into molecules called ketones, which provides the body with energy in the absence of carbohydrates.

The keto diet accelerates body fat burning this way once the body is starved of carbohydrates, using fat as an alternative fuel.

About Prüvit

Of course, the keto diet doesn’t come without its fair share of supplements. There are plenty of products out there that are made to help make your keto-journey easier, and the international keto brand Prüvit is currently leading the global market with innovative and effective products that deliver real results.

Prüvit is the world’s leading ketone supplement provider. With many different offices across various regions around the globe, they can serve almost anyone who wants to try them out.

Prüvit offers supplements for keto dieters in the form of the Keto//OS, short for Ketone Operating System. The Keto//OS is Prüvit’s flagship product with two variants available for purchase. Their latest release, the Keto//OS NAT, proves to be a very welcome addition and one that’s worthy of the name that its predecessor, the Keto//OS MAX, made for itself.

KETO//OS® NAT™

Pruvit Keto//OS NAT Heart Tart Charged (5 Single Server Packets)

The Keto//OS NAT is Prüvit’s latest addition to their line of ketone supplements. The NAT (Nutritionally Advanced Technology) is based on the existing technology that the company used for the MAX, so anyone who has used the MAX before can expect some similar effects after taking in a serving of the NAT, but with much more than what its predecessor originally provided.

How It Works

The Keto//OS NAT comes in packs of naturally fermented ketone salts that you dissolve into a glass of water. The natural process that Prüvit uses to create the NAT ensures that the product is free of any synthetic materials.

The NAT’s salts help boost the natural keto diet process, helping you reach that state of ketosis that’s essential to the diet’s effectiveness. The NAT makes it so reaching that state of ketosis isn’t as grueling.

Drinking KETO//OS NAT gives your body a burst of exogenous ketones or ketones that come from outside of your body. It may not sound like much but this actually allows you to experience ketosis without having to wait for your body to further adapt to your revised diet.

Benefits

The KETO//OS NAT is formulated to encourage weight loss and is formulated with special ingredients that can suppress your appetite. The appetite loss is complemented by the proprietary N8 Max NAT Blend, which helps you reach ketosis faster. Faster ketosis means faster fat burn and more energy for you, so you won’t have to deal with feeling sluggish while your body adapts.

The blend is also mixed in with Prüvit’s C-Med 100 Rapid Repair formula which accelerates your body’s ability to recover. This formula makes sure that your body minimizes health risks, which is one of the keto diet’s most notorious points.

Perhaps the biggest benefit you’ll get from NAT is that you can get to experience ketosis without fully committing to the keto-lifestyle. You’ve probably heard people complain about how hard keto is and it’s true; going on a keto diet demands a lot of attention to what you eat and even more dedication for when things start to feel irritating.

When you go on a keto diet, expect to feel weak because of the diet’s aversion towards carbs, and expect to feel very frustrated a lot of times since hunger tends to do that to the best of us. These frustrations are exactly what KETO//OS will allow you to bypass thanks to its unique blend. No, you’ll still have to go on a diet but you’ll get to experience keto’s benefits a lot faster!

Ingredients

The ingredients used in Keto//OS NAT’s blend stays true with Prüvit’s commitment to high-tech health. The NAT is made up of a slew of nutrients but ultimately, the ingredients used depends on what flavor you’re looking at. The Harvest Sunrise flavor, for example, is broken down as follows:

  • Vitamin B12 (100mcg) 
  • Vitamin B6 (5mg)
  • Carbohydrates (5g)
  • Sugar Alcohol (4g)
  • Sodium (910mg)
  • Magnesium (235mg)
  • Calcium (230mg)

Meanwhile, the proprietary N8 Max NAT Blend makes up 12.6g of each keto packet and remains constant across the different variants of the product. The blend includes:

  • R-Beta Hydroxybutyrate (KetoNAT) 
  • L-Taurine
  • Fermented L-Leucine
  • C-Med 100

Apart from the previously mentioned ingredients, the Keto//OS NAT is equipped with the patent-pending KetoNAT BHB Salts. This is the primary ingredient that drives your body into ketosis faster. These BHB salts are composed of compounds that directly inject ketones into your body, eliminating some of the time it takes for your body to slowly get used to the keto cycle.

Prüvit does not specify how much of these BHB salts are found in their products, however, so the amount of it found in each serving is still up in the air.

Flavors

KETO//OS NAT comes in a variety of different flavors, although the availability of each flavor may depend on the region. NAT can come in Harvest Sunrise, Swiss Cacao, Maui Punch, Lime Time, Colada Bliss, Vanilla SKI, Poppin’ Pear Apple, Raspberry Lemonade, Heart Tart and Splash flavors.

You have to hand it to Prüvit for including so many choices. You can enjoy a slew of different sweet and fruity flavors without having to worry about their impact on your nutrition and your diet thanks to all of the flavors that NAT can come in.

Charged vs. Caffeine Free

When you visit Prüvit’s website, you may notice that you have the option to purchase a pack of KETO//OS NAT that’s either “charged” or “caffeine-free”. It may be confusing at first, but it really is as simple as choosing between one version that has caffeine in it and one that doesn’t.

The caffeine content found in the charged versions might be too much for some people. Each serving of KETO//OS contains up to a 16-ounce cup of coffee’s worth of caffeine and the amount doesn’t appear to change depending on the flavor.

What you choose does matter, however. Caffeine can give you a significant burst of energy, making the charged version the perfect morning drink to take with a healthy breakfast. The no-caffeine version makes it the better option for when you to get some ketones before going to bed. The charged version will basically help you get through the day while the no-caffeine version is the choice to get if you want to keep your ketones in check while you sleep.

When Should You Take it?

Prüvit recommends a daily intake of two Keto//OS NAT servings: one serving in the morning and another a few hours before going to sleep. The company also suggests you increase your daily water intake by half of your body weight into ounces per pound.

User Feedback

The KETO//OS NAT received relatively positive if average reviews from buyers. Many users praised the Raspberry Lemonade version for its health benefits while its actual taste received minor backlash, with some users saying that it tasted too strong or that it tasted bad in general.

Some users also complained about the price of the product, saying there are other options out there that do the job well but don’t cost nearly as much as the KETO//OS does.

On a different note, some users said they ended up experiencing bad side effects like diarrhea and constipation.

KETO//OS NAT is a great product but despite that, it isn’t perfect. It still has its list of pros and cons which may or may not sway people’s opinions:

PROS
  • Each flavor has a caffeinated and non-caffeinated version
  • Has proven health benefits
  • Provides a convenient keto diet experience
  • Healthy and vegan-friendly
CONS
  • The taste is subjective
  • Expensive
  • May cause side-effects

KETO//OS NAT vs. KETO//OS MAX

The NAT is Prüvit’s latest product, directly succeeding the previous KETO//OS MAX. The NAT is built off of the MAX’s existing formula, however, and the difference between them is minimal. When you compare the ingredients between one variant of the NAT with one variant of the MAX, you’ll see that the difference is minimal. The chemical compositions between each remain largely the same.

The NAT is, however, marketed as the first product in the world that features ketone salts created by a naturally fermented process. Whether that process yields any significant advantage for the NAT may still be up for debate.

Is it safe?

The product is safe but users may experience side effects when drinking it. It’s also important to note that any side effect or negative consequence that may occur after drinking KETO//OS may not be completely related to the product at all.

One should understand all of the risks that the keto diet presents before attempting to buy this product, or even try doing the keto diet in the first place. If you jump straight into the keto lifestyle without doing any research, then you might experience nausea, constipation, abdominal pain, and other similar symptoms. Make sure your body is ready before you buy any supplements.

When Can You Expect Results?

The ability to help you reach ketosis is one of KETO//OS’s biggest selling points so you may find yourself asking. “When can I start seeing results?”

Prüvit recommends taking KETO//OS products twice a day in order for you to see results as fast as possible, but you should also take how your diet is going into consideration. Don’t forget that KETO//OS is meant to help you get into ketosis, but you’ll have to put in that extra effort to make sure you get the most of your dieting efforts.

A Few Things to Consider

The KETO//OS NAT line of keto diet supplements promises a lot but none of its official sources really provide any concrete evidence that backs up any of its many claims. Yes, Prüvit’s claim of innovation via the use of their patented BHB salts may be undisputed, but it’s hard to justify KETO//OS NAT’s price point on innovation alone.

Prüvit does have a 59-minute test that challenges any doubt you may have, though. It encourages people to buy a ketone strip to see if their product works or not but as mentioned above, there aren’t many testimonies available.

Its current user-base seems to be generally receptive to how the product tastes and the majority of customers did say that they experienced positive results. The problem with random user feedback is you’re never really sure if their experience is a result of the product working as intended or if it’s just a placebo, or even if it was due to other efforts they put into dieting.

Overall, KETO//OS NAT is still a good product. Getting ketones from an outside source is great for people who want to try keto out since it eliminates a lot of the usual hassle that the diet is notorious for. However, the price point and the overall uncertainty surrounding the product may dissuade people from trying it out.
