Using an exogenous ketone supplement, like Pruvit Keto OS, may help you achieve ketosis faster, supplement your body with electrolytes, suppress your appetite which in turn could help you lose weight.
Here is our guide to Pruvit Keto OS (short for operating system) supplements. You’ll find out how it works, what is in it and how to use it.
What is Pruvit Keto OS?
Pruvit Keto OS (Ketone Operating System) is a ketogenic supplement drink. It is designed to elevate blood ketone levels, which are naturally produced by the body for fuel.
On traditional diets, your body uses carbohydrates for energy, by converting carbohydrates to glucose. On carbohydrate restricted diets, such as the keto diet, your body burns fat for energy instead of carbohydrates.
During the process of burning fat, ketones are produced by the liver. This also happens during periods of fasting or starvation. Your body then uses these ketones for energy production.
An exogenous supplement (exogenous meaning produced external to the body), helps provide your body with ketones to reach a state of ketosis faster, or maintain ketosis when following a low carb high fat (LCHF) diet, such as the ketogenic diet.
The benefits of exogenous keto supplements such as Pruvit Keto OS when used in conjunction with a ketogenic diet have been the topic of many scientific studies. These studies have shown that exogenous ketones can assist with greater weight loss, management of diabetes, appetite suppression and memory enhancement.
How to Take Pruvit Keto OS
Keto OS is a powder that comes in single serve packets for convenience. Keto OS is available in both a ‘CHARGED’ version and standard or non-charged version. The only difference here, is the ‘CHARGED’ version contains caffeine.
To drink Pruvit Keto OS, you mix one sachet with 12 to 16 ounces of water and consume straight away. You can use still water, or sparkling water.
You can also get creative with different flavors and make keto shakes or smoothies using almond milk, coconut milk or your preferred low carb milk.

What is Pruvit Keto OS NAT?
Keto OS NAT is the updated version from the original Keto OS. It was introduced by Pruvit in 2019 and replaces Keto OS MAX.
NAT stands for Nutritionally Advanced Technology. Pruvit have used a naturally fermented process to create a keto supplement that is as close as possible to ketones produced by the human body.
Keto OS NAT contains Inner Bark of Uncaria Tomentosa, also known as the herb cat’s claw. This has been patented by Pruvit as C-MED 100.
Pruvit claim that C-MED 100 promotes DNA repair. We went searching for studies linking the Inner Bark of Uncaria Tomentosa with DNA repair. We did find this study linking Inner Bark of Uncaria Tomentosa with use in osteoarthritis patients, showing a reduction in pain during activity.
Is Pruvit Keto OS Safe During Pregnancy?
Pruvit Keto OS NAT is not for use during pregnancy or breastfeeding. It is not the ketone salts that are the issue, it is the Inner Bark of Uncaria Tomentosa (Cat’s Claw) or as patented by Pruvit C-MED 100.
Science direct reports that cat’s claw is not for use during pregnancy or during breastfeeding. In ancient times, it has also been used as a contraceptive and may interfere with normal functioning of the ovaries. If you are planning to become pregnant in the near future, please stop taking this supplement.
What is Pruvit Keto Max?
Pruvit Keto Max is an older name, which has now been replaced by Pruvit Keto NAT. There is also a slight difference in the ingredients between Pruvit Keto MAX and Pruvit Keto NAT.
Pruvit Keto MAX contains no C-MED 100 (as above, also known as cat’s claw or Inner Bark of Uncaria Tomentosa).
In 2020, Pruvit Keto Max no longer appears on the Pruvit website. You can still find Pruvit Keto Max on Amazon in some flavors, in both CHARGED (includes caffeine) and caffeine free versions. As this is an older product now, be sure to ask about the best before dates before purchasing.
What is Keto OS PRO?
Pruvit Keto OS Pro is a combination of exogenous ketones, medium chain triglycerides and C-MED 100.
Medium chain triglycerides (MCT) are very good for your body, converted into ketones by the liver almost instantly and despite being a fat, do not cause fat gain, unless of course you are going way over your macros daily.

How to Start Pruvit Keto OS
Exogenous Ketones are great to use if you are looking to get in Ketosis quickly. After all, who doesn’t want more energy, focus and control over their cravings?
Pruvit recommend taking their ketone supplements twice a day. Generally, you take a ketogenic supplement first thing in the morning, then again in the mid afternoon (that time around 3pm when you would usually reach snack, coffee or sweet pick me up…).
It is up to you whether you want to use Pruvit Keto OS once per day, or twice per day.
If you are exercising, you could also consider using a ketogenic supplement prior to exercise for that extra boost.
A great way to get started on Keto OS supplement is to purchase the 10 day drink challenge. This pack includes 20 sachets of Pruvit ketones (10 x caffeinated and 10 x non-caffeinated).
Not only do you get to try a mixed variety of flavors, you get access to the private Facebook community, Pruvit coaches and additional hacks to get you started. Click here or on the image below to purchase from Pruvit.
Before starting any exogenous ketone supplement (not just Pruvit), ask yourself:
Are you already on a Ketogenic Diet?
If you’re on a Ketogenic Diet then taking an exogenous ketone will help your body get into ketosis quicker and help burn fat and boost your energy. However, if you’re not on a Ketognic Diet and are just looking to burn fat and get energy, taking a Ketogenic supplement could be a waste of your money.
What’s inside the supplement?
Does it have actual Ketones or does it just say it’s Keto? Also you’ll want to avoid unnecessary additives that can throw off your diet.
Are you testing your ketone levels?
If you’re not, it is advisable that you do, so you can see how much exogenous ketones you should take to get yourself in ketosis. You might find a sweet spot for your body where you feel great while you have lots of energy.
Remember to treat exogenous ketones as a tool, and not a replacement for a clean Ketogenic Diet. If weight loss is your goal, you should not load up on a carb laden meal, then follow it with a ketogenic supplement such as Pruvit Keto OS to put you back into ketosis.
This is not good practice and simply promotes an unhealthy lifestyle. Take a look at our favorite ketogenic cookbooks and use exogenous keto supplements such as Pruvit Keto OS in conjunction with a balanced keto diet.
Benefits of Pruvit Keto OS
The main benefit of Keto OS is the claim that it will allow you to get to a nutritional state of ketosis within 60 minutes of consuming the drink. But what does this mean to you?
Can Help You Reach Ketosis Quickly
Keto OS contains both beta-hydroxybutyrate and MCT powder. Combining beta-hydroxybutyrate and MCTs has shown to effectively raise levels of ketones in the blood without dietary change.
May Help You Lose Weight
Studies have shown that n increase in ketones in the body have been linked to a reduction in appetite. Therefore supplementing with an exogenous Ketone like Keto//OS can be potent way to reduce your appetite.
Can Help You Beat The Keto Flu
The Keto Flu are symptoms such as nausea and fatigue that can occur when you first start a Ketogenic Diet. By raising ketone levels, Keto OS can help overcome those symptoms.
May Prevent Effects of Aging on The Brain
Exogenous ketones have been shown to help improve mental function in numerous studies. One promising area that is being researched is people with Alzheimers disease.
An increase BHB levels in these memory impaired adults lead to an improvement in cognitive performance.
Research has also suggested that exogenous ketones help reduce neurological damage related to Parkinson’s disease and epilepsy.
Can Help Endurance
Exogenous ketones have been shown to help athletes run further than athletes who drank carbohydrates or fats.
This is because being in Ketosis can help prevent the depletion of glycogen levels, which means Keto OS can help you run longer and work out for longer periods of time.
Pruvit Keto Side Effects
Pruvit Keto OS just like any other exogenous supplement, and should be taken in consultation with a doctor. If you have any medical conditions such as diabetes, ketone supplements like Pruvit Keto OS can reduce blood sugar levels. It is important to keep your general practitioner informed and monitor your blood sugar levels closely.
What are the other potential side effects?
- Stomach distress (aka diarrhea) – Keto OS is known to sometimes cause stomach issues. Start with a small dose and work your way up.
- Bad Breath aka Ketosis breath – Elevated ketone levels can cause you to produce bad breath. Its not that bad, an is actually a little sweet. It is otherwise known as acetone breath. Keep some sugar free mints on hand.
Can You Buy Keto OS Samples?
Pruvit Keto OS is available in single serve sachets, usually sold in packs of 5 or more. You can find them easily on Amazon. This is a cost effective way to try out these exogenous supplements without having to buy a whole tub.
I’d otherwise recommend trying the Pruvit 10 day challenge, where you get 20 sachets in various flavors. It’s a great way to try out to the product. Click here to buy from Pruvit.
Is Pruvit Keto OS the Best Exogenous Ketone Supplement?
Pruvit is an excellent exogenous ketone supplement, backed by research. Their supplements are formulated with additional vitamins, minerals and herbs to support your overall health.
Their range of flavors is outstanding and the taste among the best I have ever tried. I believe this is because Pruvit sweeten their supplement drinks with a combination of erythritol and a stevia extract (Rebaudioside A).
