KETO//OS Pros and Cons

CONS

Aside from the digestive issues, a lot of folks simply don’t like the taste of KETO//OS. Add in the extortionate price tag and Prüvit’s multi-level marketing (MLM) platform – yep, here we go again – and the cons of this product really start to pile on. And it doesn’t work, or not the way Prüvit claims it does. Users reported headaches as well. The diuretic effects have users in the bathroom a lot. We’re getting neck-deep in cons, now.

Unfortunately, this very expensive product simply does nothing at all. Perhaps it works on selected individuals, but not for me, 58 year old male, 80 pounds over weight. Used in conjunction with better diet and more exercise. I GAINED WEIGHT over 1 month of use. Too expensive for those kind of results.

PROS

The one thing KETO//OS does seem to have in its favor is that it can help folks who are already on a low-carb, paleo, or keto diet to offset the utter misery of “keto flu”—a period of lethargy, often dizziness, brain fog, and a severe craving for carbs—in the early stage of starting such a diet or recovering from a weekend of having fallen off the low-carb wagon.

From a reviewer of a 3-pack of the On-the-Gos (more or less a sample pack, $16.29 at Amazon):

This product is great. I Used this to ward off the keto flu and after a weekend of some bad eating to help get back into ketosis. I like the fact that this product came in a three pack because I know canisters of ketones go for about hundred dollars and this is a great way to try them out before dropping a mint on something you might hate. The orange cream flavor wasn’t bad either.

NOTE:  Often folks who bought from a rep will leave reviews on Amazon, so we use those because Amazon reviews tend to be brutally honest.

How Does KETO//OS Work?

Using KETO//OS is fairly simple:

Dissolve 1 heaping scoop or [On-The-Go] pack in 12-16oz. of cold water and shake/stir vigorously.

Therapeutic dose = 1 daily serving
Optimal performance = 2 servings AM/PM [3]

So what exactly does it do?

Or better yet, a question asked right on the Prüvit website:

Why would I take KETO//OS®?

Supplementing with exogenous ketones allows you to experience ketosis – the benefits of elevated blood ketone levels, without having to follow such a restrictive ketogenic diet, or super low carb diet, which is often difficult for some people to adhere to. Optimize your human potential. [3] (emphasis added)

So something about this formula drops you into ketosis while still being able to enjoy all the carbs you want—seriously, the very next answered question claims you don’t have to change your diet at all. Where have we heard this before?

The Magic Ingredients

The magic ingredients are apparently beta hydroxybutyrate (BHB) salts and MCTs. So let’s see what sort of magic we’re dealing with.

BHB Salts

The definition of BHBs on the website is a tad technical, but the gist seems to be that they’re a chemical “salt”—a combination of an acid and a base (neutral)—found in foods like milk and eggs. Sodium, potassium, and the ketone body beta hydroxybutyrate exist in combination until you ingest it; then it breaks up, the sodium and potassium get absorbed just like they do from other foods, and the BHB is left to do its thing by putting ketones directly into your blood system. Ketones act as a diuretic (urine producer), therefore tend to drain sodium, calcium, potassium, and magnesium from your body, so it’s recommended you increase your sodium intake while on this.

MCTs

MCTs are medium-chain triglycerides—information that was not on the Prüvit website; I had to go back to WebMD for a definition:

Medium chain triglycerides (MCTs) are partially man-made fats. The name refers to the way the carbon atoms are arranged in their chemical structure. MCTs are generally made by processing coconut and palm kernel oils in the laboratory. Usual dietary fats, by comparison, are long-chain triglycerides. People use MCTs as medicine. …

Athletes sometimes use MCTs for nutritional support during training, to increase exercise performance, for decreasing body fat and increasing lean muscle mass, and for weight loss. …
MCTs are a fat source for patients who cannot tolerate other types of fats. Researchers also think that these fats produce chemicals in the body that might help fight Alzheimer’s disease. These fats might also result in weight loss because the body uses them in a different way to other types of fats.

KETO//OS also contains caffeine – the anhydrous (lab-created) version – which is probably where all that concentration and energy comes from. They do offer a caffeine-free version.

The mix comes in several flavors, in both the regular and caffeine-free versions: Raspberry Lemonade, Swiss Cacao, Maui Punch, Chocolate Swirl, and Orange Dream. You can buy it in a tub and scoop your servings, or buy handy On-The-Go single packets. A thirty-day supply costs a whopping $160 (tub) plus shipping and handling.

There’s no diet plan, no exercise plan, just a powder that apparently can set your body into ketosis even after you’ve had the Big Mac, fries, and chocolate shake (that’s 194 carbohydrate grams in one meal).

back to menu ↑

Is KETO//OS Dangerous?

BHBs are a natural substance and MCTs are used as medications. However, if you’re caffeine-sensitive, the anhydrous stuff is just about the worst thing you’re going to ingest. You can choose the caffeine-free version if you want to alleviate that issue.

Reviews have mentioned KETO//OS causing digestive distress, which is never any fun to deal with.

Some of the drink mix flavors do contain taurine. Back to WebMD:

“Taurine is an amino sulfonic acid, but it is often referred to as an amino acid, a chemical that is a required building block of protein. Taurine is found in large amounts in the brain, retina, heart, and blood cells called platelets. The best food sources are meat and fish. …”

Insufficient Evidence for: …

Fatigue. Early research suggests that taking an energy drink containing taurine prior to driving may reduce driver fatigue. …

Exercise performance. Research suggests that taking 1-1.66 grams of taurine before exercise does not improve overall exercise performance. Using products containing taurine combined with other ingredients might improve cycling performance but not strength training or sprint performance. …

Mental performance. Early clinical research suggests that taurine, in combination with caffeine and B vitamins (Red Bull Energy Drink), can improve attention and reasoning in adolescents, but does not improve memory. …

Taurine is POSSIBLY SAFE for adults and children when taken by mouth in appropriate amounts. Taurine has been used safely in adults in studies lasting up to one year. It has been given safely to children for up to 4 months. …

[But] Not enough is known about the safety of taurine in pregnancy and during breast-feeding. Avoid using it. … There is some concern that taking too much taurine might make bipolar disorder worse. … [6] (emphasis added)

The same article warns of taurine interactions with lithium, often prescribed for depression and bipolar disorder.

While KETO//OS is likely not dangerous, there are several conditions under which caution should be exercised.

The Bottom Line

Overall, what seems to be a really great idea and a cool product is nothing more than a waste of time and money. Marketed as a magic pill and then sucking customers into an expensive, pushy MLM sales pitch, KETO//OS doesn’t do what it claims. It maybe works as a recovery tool for keto-flu sufferers, but even then it’s terribly expensive for any sort of regular use. Cross this one off your list.

Prüvit’s KETO//OS stands for “Ketone Operating System.” It’s a drink meant to help rev up your metabolism to burn fat, improve concentration, and energy. The idea is to send your body into a constant state of ketosis, defined by Google’s dictionary as such:

A metabolic state characterized by raised levels of ketone bodies in the body tissues, which is typically pathological in conditions such as diabetes, or may be the consequence of a diet that is very low in carbohydrates.

WebMD simplifies the definition further:

Ketosis is a normal metabolic process, something your body does to keep working. When it doesn’t have enough carbohydrates from food for your cells to burn for energy, it burns fat instead. As part of this process, it makes ketones.

Low-carb, paleo, and keto diet programs all aim for this state to one degree or another. You measure your ketone levels with a little paper strip held in your urine stream, rather like checking the pH of your water or soil.

But just because KETO//OS drink mixes claim to put your body into a state of ketosis, doesn’t mean they follow through.

    I agree with you on most of the article. It DOES put you into ketosis BUT you can NOT eat whatever you want. You still have to follow a low to no carb diet unlike what the product says. Basically this product puts you into ketosis quicker than if you’re doing it on diet alone and when you cheat you can get back into it quicker. It also does help with energy and my mood. The digestive issues only occur in the beginning when your system is getting “cleaned out” and if you’re eating carbs and sugars like you aren’t supposed to. Keto OS is just a helper, it’s definitely not magic. They should be more up front about the diet aspect.

  2. I have been on Keto//OS for just over one and a half years. Prior to finding Prüvit’s Ketones I was doing the Atkins diet for 11 weeks. I lost 11 lbs. Added the Orange Dream keto//OS for the next 11 weeks and stayed low carb but cheated way more than the first 11 weeks …I lost an additional 33 pounds!!! Felt AMAZING Energy and focus!!! Now I am even less strict and have lost 95 lbs!!! I still have 75 lbs to go and have switched to Prüvit’s MAX Maui Punch or Swiss Cacao. Occasionally, I take the MAX Raspberry lemonade. Regardless, I take it twice a day. I LOVE IT!!! I don’t ever remember feeling this ON!!! My Endo Dr is shocked and delighted since 18 months ago she told me my liver was dying of NAFL Disease, dispite my borderline diabetes, HB, and bad ratios of Cholesterol. As far as the price and community based marketing…. Because I have helped friends get better health back I get mine for nearly free!!! The community and company leads with education. As far as I am concerned the more people I can help by sharing this amazing product the better. Ketones benefit bodies and brains. That is a win-win. We are all made to be fueled on ketones!!! This is the best bio-identical ketone available!!! I would love to help people feel better by shaking up powdered ketone salts into their ice water!!! Mark my words….everyone needs ketones and we are all just starting to figure that out!!! Some faster than others!!! Just try it for yourself!!! Tap into your better you!!!

    Today is my 30th day using the product. I don’t know if it is a placebo effect or if it actually works but I have lost 16 pounds. I am the type that can never lose weight or gain it for that matter. I hovered around 230 all the time no matter my diet or exercise routine. I am now at 214 and feeling great! I have followed the Keto diet and stayed under 30 grams of carbs with my fat intake around 60% to 70% and protein around 20% to 30%. The first two weeks I stayed under 20 grams of carbs. I bough test strips about a week in and have not found myself out of Ketosis the entire time, even after a couple cheat days in which I consumed over a 300 g of carbs from some Goose Island IPA. I have not changed my workout routine which consists of Planet Fitness 30 min express workout 3 days a week and playing disc golf twice a week. So take my experience with Keto//OS and the other information how you want, it got me motivated to change my diet and it has worked. I look forward to losing another 14 pounds to get to my goal of 200.

    I purchased this product with the promise that if I didn’t see any positive results, I would get my money back with the “90 day money back”. I did not have ANY positive results. I tried all the coach suggestions. I gained weight and had diarrhea every time I took it. Then, I tried to return it…and was told the policy changed and they would only take it back if it was unopened! I am still fighting to get my refund. Buyer beware with this company!!

  5. I don’t think the product is truly getting you into ketosis faster but it is helping you to eventually get there by having quicker weight loss results (whether it is just fluid or not it is still a positive result) which keep people motivated and without all the side effects that come along with changing your bodies fuel source like headaches and mood swings

    I was researching this product as I seem to do better on low carb (I’m a carb & sugar addict). I prefer to go running while caffeinated, so that level doesn’t bother me. I’m reading these comments and just rolling my eyes.
    People – Mr. Ferguson is simply stating that, if you start using a product, in conjunction with cutting back on simple carbs as instructed to by said product, you will lose weight quickly in the beginning. You might get excited thinking its because of the supplement. Most of it in this first stage is simply water weight. If this is the first time doing a low (<30g) carb, it's pretty exciting! Almost a miracle!
    I can usually cut down on carbs and go into ketosis pretty quickly, and I usually do this once in awhile to kick start dropping water weight.
    As for the people who are focusing on the whole "120 cups of coffee" comment… really? These are the ones who need a "sarcasm font" to help them get a joke.
    The name calling and arguing is just hilarious. I commend Turd for actually trying the product and am excited to hear his final thoughts.
    Funny, the one person that everyone is attacking is the one person who might sway my decision on trying or not trying this product.
    Please let us (me) know how it goes!

  7. About 6 weeks ago I said “YES” to BETTER!!!

    I ordered my Keto/OS Orange Dream and Chocolate Swirl !!! For 5 weeks I have been drinking my Ketones everyday!! For the most part it’s only been once a day! There are some days I have drank my Ketones twice a day. This drink has helped me in so many ways! I have slept better then I have in many years! I wake up feeling refreshed and ready to start my day! I have more natural energy to play with my 2 wonderful kids, and get everything I need to in my day done. I have better focus and can finish something I started. I have control over my appetite for the first time ever! I am not drinking soda, or eating sugar, I eat smaller portions and I am not craving nasty fast foods!

    I already have the product. I have OS and the Kreme coffee creamer. My mother bought them and I told her I’d try them out for her as the guinea pig and order her more. I’m a 5 days into taking it daily. I got into keto in 3 days, not 45 minutes. To me, so far, the supplement is very good for sustained energy, but so far I think it’s hardly worth spending $100 per month on it. Will update in a couple more weeks.

  9. Have lost weight while using this product but I’m also following an alkaline diet so not really certain which is being more effective. The problem I have is getting the product shipped. First time got an email with a tracking number but when I checked it UPS read ‘voided.’ Contacting the company was a long drawn out process even though my credit card had been charged! After two weeks finally got the order but no explanation. Ordered a second time and still waiting two weeks later…even though company updates says it’s in Canada! No response from support! I think it should be illegal to charge a credit card before shipping. Wish I could find a consumer advocacy group to register a complaint against Pruvit Canada!

  10. Well I was trying to find negatives facts about this product because I been taking for 7 days, and experience results that I wasn’t expecting you ever heard that “Desperated people do Desperate things” I’m one on the list been having 2 back surgeries first one to release a pinch nerve second one 4yrs apart back in November 2016 got a titanium infusion (sorry I’m not that great In medical terms Spanish is my primary lenguage ) however disaster happens and I’m also the chosen one I have another incidident while boating last Sunday can’t explain how terrified my husband and my son and myself was I knew that will be another journey of pain!! For our surprise we drove back home and I was in a pretty good shape by Monday we where expecting me getting stuck on bed and or going to ER nothing happend I’m all bruise from my back but painless active like when I was 20 and a great spirit wherever is a placebo or not I’m extremely amazed for this alone my body elasticity has improved not without mention for last that I lost 3 pounds on my 5 day (last Monday) no really changing a diet, quit drinking a full pot of coffee because I don’t have the desire anymore I been drinking the orange version without caffeine did I got my money worth absolutely yes especially when I don’t have to be taking methocarbamol 500mg every 6 hours and heavy dosis of painkillers that was keeping me feeling worst than a zombie don’t want to make this long but if you want to take the change try it I bought it because a friend offer it and couldn’t tell her no, right know I’m so glad that couldn’t say no and I try it

  11. While I will definitely agree this product will not put your body in nutritional ketosis, I do think this product works great as a pre-workout for people already following a ketogenic diet. You can’t add ketones and lose weight. Ketones are a by-product of your body burning fat for fuel. Ketones do not make your body burn more fat. It could be what people are experiencing is a bit of satiety from this and therefor aren’t eating quite as much. My $.02.

  12. Well I’ve been doing this for about two months … I started at 186 pounds and 12.5% body fat… ice since dropped to 168 and less than 8% body fat… Yes it does jump you into ketosis …1 serving has kept me ijn ketosis for 5 days so I would say the supplement is washed out by then … Not a reliable website or research done by this site …. anyone with any real questions or concerns are welcome to cokntact me directly … “everything on the internet is true” – Abraham Lincoln

  13. I have Myalgic Encephalomyelitis and my #1 complaint is constant fatigue, I’m on day 3, and I have more energy than I’ve had in years…this is my personal journey, not a medical claim…I can also choose to take caffeinated or uncaffeinated versions. I’ve been taking 1/2 packet in the am and one at lunch, to trouble with my digestive tract and I get bouts of IBS, so I’m pleased my body can tolerate it. Like anything people inject, some can take it and others can’t.

  14. I do LCHF alone and have lost 89lbs in 11 months. This puts you in false ketosis. Have your doctor test you blood after a carb day with just Keto OS to help you. My friend that sells this lost 50 lbs with LCHF alone and added Keto Os in October and had only lost 14 more. So… hmmm. That should speak for itself.

    Sorry, but I will have to disagree with you. This is working great for me so far. Have not changed my diet at all and it has cleared up my dermatitis in just 2 weeks. Also lost one and a half kilos in that time. I definitely have more energy and looking forward to seeing what the next 4 weeks brings. Just wondering if the person who wrote the article bothered to try it out for themselves or just wanted to write something biased on which they had no personal knowledge on?

    Keto has worked great for me twice. The first time I lost 11 lbs in three weeks drinking the orange. A year later I’d gained some weight back and have been drinking the Bio max Maui punch. I lost 8 lbs in two weeks and I love the energy. Been back to drinking it six weeks now and my body continues to change. Fat is being reduced and my workouts are great! Love the energy and it does not give me the jitters at all. It’s expensive but the best supplement I’ve ever been on.
