Before Digging into Keto OS Unleashed

Keto OS Unleashed is one of many keto supplements available that are designed to induce (or help maintain) a state of ketosis. Before we discuss Keto OS Unleashed, we need to understand keto and exogenous ketones.

What is Keto?

A ketogenic or keto diet is a diet that limits the number of carbohydrates in your diet. A keto diet is similar to the Atkins diet but requires a more drastic reduction in carbohydrates, usually less than 50 grams a day.

Keto diets work on the premise that when your body doesn’t have enough carbohydrates to break down into glucose for energy, it breaks down fat into ketones for fuel. By limiting their carbohydrate intake, dieters force their bodies into a state of ketosis. As long as your body is in ketosis, it will burn fat to produce ketones for energy.

What are Ketones?

Ketones are chemicals that are produced in the liver when the body burns fat. These ketones are then used for energy.

What do Ketones Have To Do With Weight Loss?

The International Journal of Environmental Research and Public Health explains that ketones are a byproduct of weight loss associated with fat burn. They are produced when fat is burned for energy, and they are then excreted through your urine. A simple urine test can measure ketone levels, letting you know if you’re losing weight. Higher ketone levels, with normal glucose levels, indicate that you are losing weight.

Exogenous Ketones

Exogenous ketones are synthetic ketones. They are dietary supplements made in a lab somewhere instead of in the human liver. Exogenous ketones come in the form of esters or salts. Pruvit products are exogenous ketone salts.

Products Similar to Keto OS Unleashed


What is Keto OS Unleashed?

Now that we’ve discussed keto and how it works, we can tell you that Keto OS Unleashed is one of many keto supplements on the market that contains exogenous ketones. Keto OS Unleashed comes in Blue Ocean, Ruby Rush, and Eclipse.

Pruvit’s Keto OS Unleashed is intended to be a new and improved version of the original Blue Ocean flavor Keto OS. Unleashed is said to contain “ketones charged.” What are ketones charged with? We couldn’t find an answer to that. While the official Pruvit website has a “Keto University,” they fail to provide any information about their actual products. One could assume the ketones are charged by the excessive amount of caffeine present in both Unleashed flavors.

Does Keto OS work?

  • Journal of Nutrition and Metabolism — “Supplementation with the BHB-BA [Beta-Hydroxybutyrate] source will support tolerance of a restrictive dietary protocol; therefore, its application is an especially great fit as a complement to the dietary initiative.”
  • 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.
  • European Journal of Clinical Nutrition: “Caffeine intake is related to successful weight loss maintenance. Thus, consumption of caffeinated beverages might support weight loss maintenance.”

How Did Keto OS Unleashed Start?

Pruvit, the MLM company that develops and manufactures all Keto OS products, was founded by Brian Underwood, Terry Lacore, and Chris Harding. The philosophy behind Pruvit is to make people better.

While Pruvit claims to be a “bio-hacking” lifestyle company, the reality is that they are a multi-level marketing company. Multi-level marketing companies recruit unpaid salespeople to sell their products. The salespeople pay a considerable fee to purchase a starter kit and resell the product for a profit.


Keto OS Unleashed Claims

Keto OS Unleashed is the new and improved version of other keto products from Pruvit. It has 30 percent more exogenous ketones and more than twice the caffeine of different formulas.

Pruvit claims that Keto OS Unleashed:

  • Repairs DNA
  • Gives athletes the rush they need for increased performance
  • Increases concentration
  • Preserves muscles
  • Suppresses appetite
  • Ends insomnia
  • Improves digestion
  • Decreases the likelihood of keto flu

Keto OS Unleashed undoubtedly sounds excellent, but is there any evidence to support the claims made by Pruvit? Our research team took a look at the ingredients in Keto OS Unleashed to find out.


Keto OS Unleashed Ingredients

The main ingredients in Pruvit Keto OS Unleashed are:

  • KetoNAT
  • L-Taurine
  • Fermented L-Leucine
  • Black Fulvic Acid Powder
  • C-Med 100
  • Caffeine
  • Stevia Extract

N8 Bioavailability Blend

The N8 Bioavailability contains:


Taurine is an amino acid that contains sulfur. This Experimental and Clinical Cardiology study shows that taurine may have a positive effect on cardiovascular health.

Fermented L-Leucine

L-leucine is another amino acid that is responsible for muscle health.


Caffeine is a stimulant that does not increase athletic performance, at least not according to multiple scientific studies, including this Journal of Obesity Research, published study.

Realistic Results

Does Keto OS Unleashed Work?

For Keto OS Unleashed to work, a keto diet would have to be effective. There is mounting evidence that shows a keto diet is no more effective than a low-calorie diet. As JAMA reported, a randomized trial concluded that there is little difference between a low-fat and low-carb diet when it comes to the number of weight dieters lost.

For the sake of argument, let’s say that a keto diet is an effective way to lose weight. Do the exogenous ketones in Keto OS Unleashed induce a state of ketosis? The official Pruvit website offers no fact-based evidence to show that they do. Some studies, like this one from the Frontiers in Physiology, show exogenous ketones may be beneficial to your health, but the results are preliminary.

Details on Keto OS Unleashed and Weight Loss

You will lose weight on a ketogenic diet, whether you take Keto OS Unleashed or not. Other than medical uses, weight loss is the main reason people switch from carb-based energy to fats. But, this type of eating has been around for centuries and has worked perfectly well without supplements.

How to Use Keto OS Unleashed

Keto OS Unleashed comes in packets of Amped Blue Ocean and White Midnight. Mix one of these packets with 16 ounces of cold water and stir vigorously. Keto OS Unleashed should be taken in addition to following a ketogenic diet.
