Keto OS NAT Review - 14 Things You Need to Know

Does Keto OS NAT actually work, or is the brand selling you a pipe dream? Ketogenic diets and supplements are all the rage in contemporary fitness programs. Companies often advertise ketogenic products as “breakthroughs” or missing links to ultimate weight loss. The point of using any such product is to help the body reach ketosis, a metabolic state in which the body burns off stored fat for energy.

Keto OS NAT is the latest product to promise to help you reach ketosis quickly, but what did our research team uncover?

Keto OS NAT can be purchased through their Official Site.

Overview

What is Keto OS NAT?

Keto OS NAT is a new product line of fermented ketone supplements. As the acronym NAT means “Nutritionally Advanced Technology,” this brand supposedly uses the latest technology to deliver ketones to your body safely.

According to the company, the heightened number of ketones from Keto OS NAT also suppresses the appetite, allowing your body to burn off existing fat reserves, but what does science say about the ingredients?

  • Frontiers in Physiology – Increased blood ketones can help the user reach ketosis.
  • Journal of Physiology – Leucine supplements helped support muscle maintenance in small mammals. Scientists caution that more studies need to be conducted on humans before confirming similar benefits.
  • Current Neuropharmacology – Caffeine is a psychoactive drug that alters the response of the central nervous system.

The parent company of Keto OS NAT claims that this product provides all-natural exogenous ketones that are bio-identical to the endogenous ketones that your body produces on its own. According to the company, the combination results in a superior number of ketone bodies for optimal health.

The product is available in caffeine-free and caffeine-charged. The flavors include:

  • Blueberry Acai
  • Berry Blue
  • Heart Tart
  • Lime Time
  • Maui Punch
  • Nat Lite
  • Naranja
  • Nat20 Fan Favorites
  • Raspberry Lemonade
  • Splash
  • Strawberry Peach
  • Swiss Cacao
  • Trü Passion
  • Hibisco

How Did It Start?

How Did Keto OS NAT Start?

Keto OS NAT started in September 2018 as a new division of Pruvit Ventures, Inc. This division advertises dietary and nutritional supplements that feature ketones as the active ingredients. Based in North Texas, the Pruvit Ventures corporation is the brainchild of serial entrepreneur Brian Underwood. Their address is 901 Sam Rayburn Hwy Melissa, TX 75454-2218 and their phone number is (972) 369-2886. Pruvit officially introduced its Keto OS NAT at the corporation’s Keto Kademy conference held in Dallas, Texas.

New for 2021: Pruvit is an MLM company even though they sell products on the website. They consider all consultants to be “promoters”. There are two levels to join with promoter packs. The mini-pack offers 5 flavors at 20 servings each for $497. The max pack offers 10 flavors at 20 servings each for $910. The max pack also comes with rewards that we think apply to your business status with the company.

Pruvit boasts an exceptional A+ rating from the Better Business Bureau (BBB), although it is not accredited by the BBB. Impressively, the company has garnered a high rating of 4.87 out of 5 stars based on a substantial volume of 416 customer reviews. Over the course of the last three years, Pruvit has effectively resolved 40 complaints, with 8 of them being addressed within the past year. This track record underscores Pruvit’s commitment to customer satisfaction and highlights their proactive approach in addressing concerns.

Claims

Keto OS NAT Claims

The Keto OS NAT brand asserts that its product line is crafted to provide natural, exogenous ketones that efficiently facilitate the body’s transition into ketosis. According to the manufacturer, the key feature of this product lies in its utilization of the N8 MAX NAT blend, prominently featuring C-Med 100. This blend purportedly supports healthy cell function, expeditiously repairs DNA, bolsters immune function, and enhances the production of essential amino acids, thereby optimizing overall bodily performance.

Keto OS NAT claims to contribute to improved mental clarity and heightened cognitive function, attributed to the proprietary blend and superior efficacy inherent in the product.

Moreover, the formulation is said to include ingredients that have demonstrated positive effects on healthy cell function, DNA repair, and increased amino acid production.

Of notable significance, the manufacturer claims that this product induces and augments appetite suppression, ultimately aiding in fat burning by controlling hunger and curbing the desire to snack. It’s important to note that these statements reflect the claims made by the manufacturer.

Ingredients

Keto OS NAT Ingredients

Because the Keto OS NAT brand prides itself on “technologically advanced” ingredients, items listed on the label may be unrecognizable to the average consumer. The following overview provides a breakdown of Keto OS NAT ingredients to determine if these components are right for you.

  • R-Beta Hydroxybutyrate – This organic compound is a beta hydroxy acid essential to the metabolism of fat. In humans, the liver’s synthesis of this compound produces ketone bodies made whenever the digestive system goes into fasting mode. When produced naturally, the compound helps convert fat reserves into energy and reduces inflammation. According to the journal Annual Review of Nutrition, the “ketone body BHB, a fasting fuel and fasting signal…offers promise for the improvement of human health span and longevity.”
  • L-Taurine – This compound is an amino sulfonic acid and a necessary building block of protein for all animal tissue. L-taurine constitutes a significant portion of the large intestine bile used for digestion, and it also helps builds proteins in the brain, eyes, and heart. L-taurine is a conditional amino acid that the body can manufacture on its own in a healthy individual. People whose bodies do not produce enough l-taurine can benefit from the supplement ingredient, but the kidneys automatically excrete excess l-taurine in otherwise healthy persons. According to the journal Biomolecules & Therapeutics, “because taurine is a naturally occurring substance that exhibits few adverse side effects and plays a fundamental role in the function of most mammalian cells, the future of taurine as an effective therapeutic agent and a nutritional supplement is seemingly bright.”
  • Fermented L-Leucine – In contrast to l-taurine, l-leucine is an essential amino acid that the body cannot manufacture on its own. Instead, most people obtain l-taurine from food or supplementation. According to the available research in the journal Nutrients, “potential beneficial effects [are] dependent on weight loss.”

  • C-Med 100 – C-Med 100 is a commercial extract of the cat’s claw vine (Uncaria tomentosa). Based on research presented from the National Center for Integrative and Complementary Medicine, “cat’s claw appears to be safe when used orally for short periods of time.”
  • Erythritol – Erythritol is a sugar alcohol made of glucose fermented with yeast. Erythritol has a zero glycemic index. Therefore, it does not cause spikes in blood sugar. Because mouth bacteria cannot metabolize erythritol for fuel, the ingredient does not cause cavities or tooth decay. However, because erythritol excretes from the body undigested, it does not send satiety signals to the brain to indicate fullness. As a result, erythritol may be an unsuccessful sugar substitute for appetite suppression.
  • Rebaudioside A – Rebaudioside A is a chemical compound that is 200 times sweeter than conventional sugar. Derived from a plant native to South America, rebaudioside A is one of the most popular sugar alternatives added to beverages and candy. Although the FDA has approved rebaudioside A for human consumption for over a decade, research published in Physiology & Behavior found that large concentrations may trigger cravings for more calories.
  • Caffeine – Caffeine is the stimulant used as an energy booster in the “charged” version of Keto OS NAT. Because caffeine can cause jitters in some individuals (or when consumed on an empty stomach), Keto OS NAT also offers a decaffeinated version.

This supplement also contains a proprietary blend of vitamins and minerals such as B6, B12, and calcium. The company advises that users should not underestimate the concentration of vitamins in the product. For example, each serving reportedly contains 4,167-percent daily value of vitamin B12.

Does It Work?

Does Keto OS NAT Work?

Foremost, Keto OS NAT claims that its fermented formula can absorb quickly to send the body into a ketosis state faster (i.e., in “less than an hour”). Since this is a brand-new product, there have been no independent studies to confirm these claims. Accurate testing for ketosis typically requires a blood test (since this is more reliable than a urine test or breath test). To verify that Keto OS NAT can work, users would need to undergo a (usually expensive) blood test within the hour to confirm whether the body has achieved ketosis.

Keto OS NAT also claims that its product line’s molecular structure works to repair cells, balance amino acids, and improve the immune system. While several of the ingredients have been shown to restore cell DNA and stimulate amino acids in laboratory animals, these methods require testing on human subjects to verify that they work on people. Finally, there is currently no evidence that the product can alter the immune system.

Benefits and Results

Keto OS NAT Benefits and Results

keto os nat benefits

Most reports on Keto OS NAT benefits come from influencers who opted to test a beta version. The primary reported benefits are the vitamin content and the energy boost while taking the “charged” version. However, users also remarked that they could get the same results from a multivitamin and other caffeinated beverage (such as tea) – without the 120.00 USD price tag. Because Keto OS NAT is a brand-new product, there have not been enough users to verify before and after photos or support the company’s purported results.

Weight Loss

Details on Keto OS NAT and Weight Loss

The new Keto OS NAT formula claims to help individuals achieve weight loss by causing the body to reach ketosis more quickly and weight-loss ingredients. According to The International Journal of Environmental Research and Public Health, a proper ketogenic diet can help obese patients achieve weight loss (usually under a physician). Medical professionals may also administer exogenous ketones at the prescription level. However, it is unlikely that a ketone supplement can cause significant weight loss without lifestyle changes like diet and exercise.

The makers of Keto OS NAT also claim that its high-profile ingredients (such as l-leucine and erythritol) assist with weight loss. For example, the brand cites a 2009 study that l-leucine supplements encouraged weight loss and an early 1990s study that erythritol may benefit low-carb diets. Most of these positive reports have been based on animal studies (e.g., rats and mice). Researchers would need to replicate the results on humans to support the belief that Keto OS NAT helps with weight loss. As it relates to artificial sweeteners, the Yale Journal of Biology and Medicine, “artificial sweeteners, precisely because they are sweet, encourage sugar craving and sugar dependence. A similar approach might be used to reduce sugar intake. Unsweetening the world’s diet may be the key to reversing the obesity epidemic.”

Directions

How to Take Keto OS NAT

To take Keto OS NAT, dissolve one packet into 16 ounces (or around 500 milliliters) of cold water. Mix thoroughly and serve. The company advises that you can take Keto OS NAT with a meal, before a workout, or as a stand-alone energy booster.

Cost

How Much Does Keto OS NAT Cost?

At times, the company provides Keto OS NAT at a discounted rate of $87.10 USD during flash sales on its official website. Periodically, the company also offers samples priced between $25.00 and $60.00 USD. Currently, the cost is $133 for a package containing 20 servings.

Side Effects

Potential Keto OS NAT Side Effects

Because the new Keto OS NAT has ingredients unfamiliar to the average consumer, it is vital to consider any potential side effects before trying the products. Users who tried the beta version of Keto OS NAT reported side effects similar to standard diet supplements or energy drinks.

Possible side effects include the following:

  • Nausea
  • Stomach Rumbling
  • Headaches
  • Fatigue (initial tiredness due to reduced simple sugar intake)
  • Jitters while using the “charged” or caffeinated versions

What Users Are Saying

What Users Are Saying

“Awesome products – Works great.”

“Very unhappy with this product. I’ve seen and read so much about the product, so I thought I would try it out. Needless to say it was a Big mistake, Nasty Nasty Tasting!!!! Spent alot of money and can’t return it, WOW!!!!”

“They put you in a deep state of ketosis and taste amazing! They make it very easy to stick to keto diet, as they supress my appetite and fulfill my sweet tooth. Its my 2nd time loosing weight on keto and i buy them now on amazon because i found the instagram influencers really annoying 2 years ago where they want you to join their team as promoter. I’m just here for the product lol I know they are expensive because you get more for your buck as cheaper brands, but they also work much better as you can see on my 30min later test. If you’re in doubt: definitely give them a try! I also like the strawberry/peach flavor.”

Bottom Line

Bottom Line on Keto OS NAT

Any brand that promises fast results appeals to our desire to look our best quickly. However, an expensive product with little “tried and true” evidence for results may not be worth the investment. Interested users should compare other ketogenic products before deciding if the new Keto OS NAT is worth the cost.

Among the best weight-loss apps we’ve seen is Noom. Their system offers users personalized meal plans, human coaching, active support groups, and so much more. Plus, Noom‘s amazing easy-to-use app makes it easier to access your goals and stay on track from anywhere.

    I tried the 10 day challenge. I didn’t sleep for the first three days. So I stopped taking them. And I’m not one to be affected by caffeine. They have no support at all. I searched their Facebook members page for help and answers and to my sales person and got no response for help how to get sleep. I even tried melatonin. They monitor all postings on their Facebook page and don’t allow any negative postings for questions.

      They have decaf flavors. I am very sensitive to caffeine and I sleep very well after drinking these. I do take melatonin to sleep but have done so long before these drinks.

      Erythritol is used as sweetener. Can be from fruits and veg. but for mass production I am sure it is a manufactured mostly from glucose.
