Our bodies were meant to burn ketones. We have a parallel system within us designed to use ketones as an energy source. Ketones are faster and more efficient than the way our bodies use glucose. Ketones give you 38 per cent more energy than you can get from glucose. We as a society are following a deceptive food pyramid. We’re operating in a high carb world where food is abundant.

There was a time, however, that human beings moved in and out of a state of ketosis with the flux of scarcity and abundance. Ketones provided animals and humans with energy in times of famine. Why haven’t we heard about this before? Ketones are a natural product that can’t be sold as a high dollar pharmaceutical, so no drug company is interested. KETO//OS is not an excuse to sit on the couch and drink beer and eat pizza. For best results, you should be following a sensible diet comparable to the Paleolithic Diet or even the Ketogenic Diet for best results.


Keto//OS is ketone supplementation that gives someone the benefits of ketosis without having to be in nutritional ketosis. It is also a tool for people that want to follow a Keto lifestyle by reducing symptoms of the Keto flu and accelerating the use of ketones as energy, thus assisting to be Keto-adaptive more efficiently and effectively.

KETO//OS is a proprietary, “first of its kind” Exogenous ketone delivery drink. Rarely does a nutritional based product come along that has the ability to make a measurable and substantial impact on health and wellness. Prüvit’s KETO//OS (Ketone Operating System) is a revolutionary drink mix that is based on a proprietary ketone energy technology that delivers advanced macro nutritionals and promotes optimized cellular regeneration, energy and longevity. Ketones are a high energy product of fat oxidation that deliver a more efficient and higher energy yield than glucose which makes them the ideal fuel for powering the human body. Ketones are traditionally only produced during times of prolonged fasting and therefore have been limited in their availability as an alternative energy source.

KETO//OS contains a specifically engineered ratio of proprietary ketone mineral salts that provide a high-energy fuel compound without having to incorporate an energy-restricted diet. KETO//OS contains a perfect ratio of ketones for optimal protein synthesis and a high fiber based MCT formulation for sustained nutrient energy and digestive health and cognition. KETO//OS assists in improving the pattern of LDL Cholesterol and increases levels of HDL (good cholesterol). KETO//OS will make you feel more energetic, more focused, more fit and healthier than you ever have. It provides an exceptional nutritional foundation to help you lose weight, feel great and perform your very best.

South Lee, Massachusetts

I was introduced to this amazing product by a friend of my husband! I was told that it puts your body into a state of ketosis which weight loss can occur. Very skeptical I tested my urine about 10 am and it was completely negative of ketones. I then drank the product and around 11am I tested it again and it definitely showed ketones in my urine!! It was amazing!! I felt great with so much more energy, and low and behold found that my appetite was definitely not the same as it was the day before!! I lost 1.5 lbs after just the first day of using the product! I can't wait to see what the future holds for me and my husbands roller coaster ride of weight loss!!

I served 5 years in Special Operations as US Army Ranger in the 75th Ranger Regiment. I've had two facial surgeries from head trauma, experienced severe anxiety, depression, aggressiveness and have suffered from ADD most of my adult life. I was prescribed Paxil, Klonopin and Adderall which I was on for 3 months with adverse effects so I quit and powered through it as best I could accepting life as it was. Since taking KetoOS, I have experienced focus like no other time I can recall, my anxiety is controlled, brain fog I never knew I had was lifted, I'm self-motivated beyond belief and being active with my fitness I've gone further, faster and feel stronger mentally and physically. I highly recommend KETO//OS for ANY Veteran so they too may start living again with purpose.



Im a wife & busy mom of 2 small children. Keto OS has given me back my sanity. No more mommy brain, hours of steady energy & focus and appetite control! Its my secret weapon! I Prüvit everyday.

  • FAQS


Start using KETO//OS gradually. Depending on an individual’s ability to metabolize fat, start with one half serving up to one serving and increase slowly over several weeks. Too much KETO//OS, especially on an empty stomach, can result in loose stool or a stomach ache. You can avoid these problems by slowly increasing your daily consumption over a few weeks to build up to higher dosages. KETO//OS consumption will increase production of fat enzymes. Because most people are not efficient fat metabolizers their body needs to start optimizing the ability to metabolize and synthesize fat. As a result you will see increased fat loss and lower your total body fat percentage. If upset stomach occurs, lower the dosage for several days and gradually increase it over a few weeks as fat metabolization efficiency increases.

Consumption of KETO//OS before exercise can result in significant decreases in oxygen demand and increases in performance. We recommend 30 minutes before a workout. Note: Pre-workout use is recommended after building up to a full dose. The best way to maximize energy, appetite control and sustain energy is to take KETO//OS first thing in morning. To maximize benefits, build up to 1 serving 3 times daily - morning, afternoon and early evening. May be used with carbohydrate supplements if desired or by itself as a non-carb, highly efficient energy source.


As with any new supplement, consult with your physician before using. If you are using any prescription or over-the-counter medicines, are unaware of your current medical condition, have any pre-existing medical condition(s), have hypersensitivity to salt or have any risk of kidney stones, consult with your physician before using this product. Build up to a full serving slowly to avoid gastro-intestinal discomfort.
