Pruvit Keto OS NAT (Exogenous Ketones) Review – What are the Other Pruvit Products & Should You Use Them?

What is Keto OS NAT and Will it Work For Me?

To find out if Keto OS NAT will work for you, you need to understand what it is and what ketones and ketosis are.

Keto OS NAT stands for ketone operating system and is the king of keto supplements. Keto Nat’s active ingredient is (R-BHB) which is a ketone salt. There are two types of ketone supplements, ketone salts, and ketone esters. Ketone esters and salts are both exogenous ketone supplements but, the main differences between them are, esters are NOT palatable, are synthetic, and are very expensive. Bioavailable Ketone Salts such as Pruvit ketones come in different flavors, allow for quick absorption of ketones, and are a better option that doesn’t cost a lot of money.

Both ketone salts and esters will induce a state of ketosis by raising blood ketone levels to 1mml or higher.

By using the process of natural fermentation, Pruvit developed Keto OS NAT as a new generation of ketone supplementation that allows greater absorption in the human body. This process eliminates the need for unnecessary chemicals or fillers that provide no value.

What’s Ketosis and What Are Ketones?

The ketogenic diet, a.k.a. “keto,” is turning into a mainstream eating routine for competitors (athletic performance), biohackers, and individuals hoping to get more fit and improve their metabolic wellbeing. At first, this eating regimen was utilized to treat epilepsy, however, the advantages of keto may stretch out a long way past the neurological framework.

While you may know the nuts and bolts of keto—for example, that it’s a high-fat and low carbohydrate diet — you probably won’t know precisely how it functions, or what ketogenic even means. Keto is a deep subject and is quite complex understanding the physiology of it all. The basics of ketones and the keto diet are pretty simple. Let’s jump in!

Ketosis – Basic Understanding

When someone is in ketosis, it means the body is burning fat for energy through beta-oxidation and turning the burned fat into ketones in the liver. Ketosis is the opposite of the metabolic state of carbohydrate oxidation or glycolysis (breakdown or burning of glucose for energy/fuel).

When our body is in ketosis it will produce BHB (ketones) through a process known as ketogenesis. When our body is in a fasted or depleted glucose (blood sugar) causing insulin levels to fall. Low insulin levels signal the body to start burning fat stores. The released fatty acids are then broken down in the liver and converted into acetyl-coenzyme A (acetyl-CoA).

An enzyme known as BHB-dehydrogenase converts AcAc into BHB. Once BHB is produced it is then transported out of the liver and into the bloodstream and used as fuel (a super fuel).

There are two types of ketosis: Endogenous and Exogenous Ketosis

Endogenous ketosis (nutritional ketosis) means that the body produces ketones on its own and you’re burning your own fat or fat from the food you eat for energy (no ketone supplements). You MUST do a Low-carb diet to achieve this and it’s generally recommended that you have medical supervision. A lot of people find this diet difficult to sustain long term.

Exogenous ketosis means the body is using ketones from outside the body (ketone supplement) as the fuel source and does not require the body to deplete glucose (blood sugar).

It’s important to note that ketone supplements can be used even when a person is doing the keto diet. This helps speed the process of becoming “keto adapted“ and can assist in fat burning and weight loss.

The use of exogenous ketones has catapulted in popularity over the last 6 years mainly due to Pruvit Ventures and the introduction of their ketone technology Keto OS MAX. Keto Max and now Pruvit’s Keto OS NAT (Nutritionally Advanced Technology) is easy to implement into anyone’s daily regimen and allows people the therapeutic benefits of being in ketosis without having to do a high fat diet or low carb diet.

Health Benefits of Pure Therapeutic Ketones | Keto OS NAT

Most of the conversations surrounding ketosis and ketogenic diets relate to how ketones are used as an energy source. Research is now uncovering new roles for ketone bodies BHB might be much more than just a fuel source for the body.

Some functions of BHB include such roles as lipid metabolism, a signaling molecule for gene expression, and improvement of metabolic rate.

According to the Pruvit website Keto OS NAT utilizes N8 MAX NAT™ BLEND featuring C-Med 100®KETO//OS NAT® supports healthy cell function, rapidly repairs DNA (improving DNA telomere length), supports healthy immune function, and elevates essential amino acids necessary for optimizing body composition.

According to Pruvit’s website, their social media and any Pruvit review you find the potential benefits are:

  • Increased Energy Levels
  • Appetite Suppression
  • Improved Mood
  • Better Sleep
  • Increased Fat Loss
  • Increased Focus & Mental Clarity

Wanting an Exogenous Ketone Drink?

If you are planning to use a ketone or BHB supplement is important to give your body what it will use and one that’ll provide the maximum benefits. All but Pruvit ketone supplements currently on the market are synthetic compounds. Pruvit’s Keto OS NAT is the only ketone supplement that is all-natural due to the patented fermentation process.

What in the World is A Fermented Ketone?

Through extensive research and rigorous testing, Pruvit discovered a way to develop ketones in the same molecular structure as a substance produced in the body or bioidentical ketones using a patented natural fermentation process, which allows the human body to utilize them and thus mimicking ketosis. These ketones are specifically known as BHB (D-hydroxybutyrate). The body responds to these man-made bioidentical ketones in the same way as ketones produced by the liver while in ketosis.

Pruvit’s ketone formula takes the bioidentical ketone a step further by creating the first and only naturally fermented exogenous ketones. All other similar products on the market require a synthetic process to bind sodium to the ketone body BHB, but not Keto OS NAT.

My personal experience with Keto//OS NAT

I drink Keto NAT for many reasons and I have been drinking it for over 6 years now. I drink it because it makes me feel better as a person. When I started drinking it I wanted more energy and I wanted to wake up in the morning and not feel exhausted. I knew I needed something in my life to get me going. Once I started drinking Keto OS NAT, I instantly started to have more energy, I started sleeping better, and I started to lose some inches. I just felt like a new person, that’s why I encourage everyone to drink Keto//OS NAT.

  1. Hi, do I take any supplements with it to avoid ‘keto flu’ symptoms? Tried 1/2 packet twice last week and felt a little crappy… lol

    • Hey Jessica! checkout the video I just posted about the Keto Flu @ as for taking 1/2 a pack twice and feeling crappy, I’m sorry. I can help you feel better but I need more information. What did you feel, when did you take it, what were you expecting to feel, etc.
      I strongly believe with starting with 1 full pack and mix in 16 -24 of water and sip on it for 30-45mins and drink it every day for a minimum of 5 days as a test. I don’t believe that starting with less or more is effective.

  2. I try to follow intermittent fasting between 7:00 pm – 8:30 am, and end up eating my breakfast around 8:30 am. What is the best time for me to have the KETO/OS NAT supplement? I got the caffeine version. Please advise as I am just starting out.

    • I’m sorry for the delay in responding. to answer your question, everyone is different , what works for me may or may not work for you. With that said, I would recommend taking your serving of Keto NAT at 8 am as it wont break your fast. You may also find that taking it around 11-2 pm works best. Bottom line is that their isn’t a bad time to take it. when you feel you need a bit of a pick me up take it then.
