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 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 in a safe manner. 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 rather than increasing caloric intake for energy. 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:

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. Pruvit officially introduced its Keto OS NAT at the corporation’s Keto Kademy conference held in Dallas, Texas.

Keto OS NAT Claims
The Keto OS NAT brand claims that this line provides natural, exogenous ketones that absorb quickly and help your body reach the state of ketosis faster. According to the company, this brand supports cell enzyme function, activates cellular DNA repair, boosts the immune system, and helps balance amino acids so that the body performs at its optimal level.
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 help you 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, synthesis of this compound within the liver 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. Research published in the journal Frontiers in Physiology, increased blood ketones can help the user reach ketosis.
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 help 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 any excess l-taurine in otherwise healthy persons.
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 Journal of Physiology, researchers found that l-leucine supplements helped support muscle maintenance in small mammals. Scientists caution that more studies need to be conducted on humans before confirming similar benefits.
C-Med 100 – C-Med 100 is a commercial extract of the cat’s claw vine (Uncaria tomentosa).
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 the purposes of 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 actually trigger cravings for more calories.
Caffeine – Caffeine is the stimulant used as an energy booster in the “charged” version of Keto OS NAT. According to Current Neuropharmacology, caffeine is a psychoactive drug that alters the response of the central nervous system. Because caffeine can cause jitters in some individuals (or when consumed on an empty stomach), Keto OS NAT also offers a decaffeinated version of the product.
This supplement also contains a proprietary blend of vitamins and minerals such as B6, B12, beta carotene, 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.
Foremost, Keto OS NAT claims that its fermented formula can absorb quickly to send the body into a state of ketosis faster (i.e. in “less than an hour”). Since this is a brand-new product, however, 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). In order 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 the molecular structure of its product line works to repair cells, balance amino acids, and improve the immune system. While several of the ingredients have shown to repair cell DNA and stimulate amino acids in laboratory animals, these methods require testing on human subjects in order to verify that they work on people. Finally, there is currently no evidence that the product can alter the immune system.
Keto OS NAT Benefits and Results
Most reports on Keto OS NAT benefits come from influencers who opted to test a beta version of the product. The primary reported benefits are the vitamin content and the energy boost while taking the “charged” version. However, users also remarked that they could possibly 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.
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 through inclusion of weight-loss ingredients. According to the The International Journal of Environmental Research and Public Health, a true ketogenic diet can help obese patients achieve weight loss (usually under the supervision of 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 those on 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 human in order to support the belief that Keto OS NAT helps with weight loss.
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.
How Much Does Keto OS NAT Cost?
Since Keto OS NAT is a brand-new product, you can currently purchase it during official website flash sales for 130.00 USD. Occasionally, the company offers samples ranging from 25.00 to 60.00 USD.
Potential Keto OS NAT Side Effects
Because the new Keto OS NAT has ingredients that may be unfamiliar to the average consumer, it is important 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:
Fatigue (initial tiredness due to reduced simple sugar intake)
Jitters while using the “charged” or caffeinated versions
Keto OS NAT Pros and Cons
Handing over your credit card for a brand-new product warrants a review of the pros and cons prior to taking the plunge. While the product has some positive aspects for people curious about ketosis, there are some definite negatives that you should keep in mind.

What Users Are Saying
“Whether it’s to wake myself up in the morning or get a boost before workout… they definitely work to aid with cravings and weight loss for me… going to try the non-caffeine ones eventually because if I take this any time after 5pm, I cannot sleep.”
“The taste is bland but okay. Not sure it does anything. Read up on it. I’m told it keeps the body from going into natural ketosis.”
“Expensive and had zero effect. Save your money.”
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.
It is important to live a healthy life, but sometimes, it can be difficult to make the changes necessary to make healthier choices and maintain a healthy weight. That’s why it’s important to choose a clinically-proven program that can help you with your individual needs.
