Which Ketone Supplement should you use?

Searching for a Ketone Supplement can be challenging if you don’t know what you need. Sure, you know you want an efficient way to get into Ketosis, but is there more than one way to do so? More importantly, which ketone supplement works best for situation and taste pallet?

It’s also important to know which Exogenous Ketone supplement will actually work. The world of supplementation is full of snake oil salesmen, keen to providing a “miracle cure” to all of your nutritional needs. Because of this, we’re going to break down some of the leading ketone supplements for you, and dissect their benefits, and if any, their weaknesses/drawbacks. It’s important to state that these supplements alone will not allow you to live a Ketogenic lifestyle. Nutritional Ketosis is the base of everything else you try while living the Keto lifestyle; it’s useless to use ketone supplements if you’re loading your face with carbs and sugars, because you’re missing the benefit of the true fat burning experience.

So with that caveat out of the way, let’s move into why you would want to use a Ketone Supplement.

Energy for “on-the-go”

One of the more difficult parts of any diet is applying its demands regularly to food preparation. The Ketogenic Diet requires you to cook with only certain types of ingredients, and eat only certain kind of foods; but what if you wake up late and don’t have time to make your loaded Keto omelet? This is where one of the convenience benefits come into play: by takng a Ketone Supplement on your way to work, you’re providing your body with energy, while also suppressing your appetite to ensure you won’t show up to work jonesing for the office junk food.

The perceived “magic” of ketones to satiate appetite comes from what scientists call an anorexigenic (loss of appetite) effect caused by cholecystokinin (CCK) – a hormone in your GI system – that counteracts ghrelin – also known as the “hunger hormone” – to stop your body from having cravings.

Sustained Energy

In America, many people choose to start their day with a carb loaded rush, which gets them feeling wired but ALWAYS leaves you feeling drained. All this does is start a cycle of carb gorging, crashing, and regourging. With ketones, this isn’t the case. Our bodies from an evolutionary standard, are wired to use fat efficiently, and to use carbs quickly. Modern times, more specifically modern agriculture, have brought us into the age of the carb heavy diet. But look what it’s done to us! Obesity, diabetes, and nutritional imbalances run rampant in a country that supposedly has an abundance of food!

With Ketone Supplements, you’re side stepping this madness. By waking up in the morning in a fasted state and then supplementing exogenous ketones, you’re giving your body the primal fuel it needs with a modern twist. You’ll go all morning with a prolonged energy that doesn’t fizzle, because you’re appealing to your body’s natural inclinations!

Getting back into ketosis when you fall off the wagon

Although we have the best of intentions, everybody occasionally indulges and falls out of Ketosis. One of the worst experiences can be attempting to get back on the horse nutritionally after you’ve splurged on carbs, most likely making you feel like crap. A solid Ketone Supplement will be a shot in the arm for you, giving your body easily processable ketones to utilize for energy, and bypassing much of the digestive requirements of solid food. This is not to say that you shouldn’t be eating keto while getting back into Ketosis; but you will get there faster by making use of exogenous ketone supplements.

Now that we have some of the major benefits listed, it’s time to check out a few of the Ketone Supplements you can make use of in your keto repertoire.

Ketone Supplement List

Pruvit’s Keto//Os Collection

We reviewed this product in our starter article on exogenous ketones (which you should definitely check out!). Keto//OS was one of the first ketone supplements available to the public, and has since grown their brand to produce not just their original Chocolate Swirl and Orange Dream, but also the new Maui Punch and Kreme flavors.

Pruvit’s blend differs slightly between products, but both contain an amount of caffeine which makes it ideal for a pre workout fuel. There are also caffeine free options if you just want the fuel and not the caffeine. To give you a better idea, here are how each supplement differs in ingredient makeup:

Keto//OS Max Maui Punch – Beta Hydroxybutyrate, Amino Acid Blend (L-taurine, L-tyrosine, L-arginine, L-leucine), Natural Flavors, Inulin (Chicory Root), Potassium Citrate, Stevia, Caffeine, Ascorbic Acid, Butyrate.

  • Comes in both caffeine, and caffeine free. Comes in single pouches for easy mixing on the go!

    Best Review: Per Amazon “The MAX works, lost 20 lbs in 18 days”

    Most Critical Review: Per Amazon “If I understand these products, they are meant to induce Ketosis. I have medical ketosis strips and can say that there is absolutely no truth to this whatsoever after ingesting the product, waiting an hour and testing with my fresh new strips. I gave it one star because it didn’t taste awful.”

    Keto//OS Chocolate Swirl – Beta Hydroxybutyrate, Amino Acid Blend (L-taurine, L-tyrosine, L-arginine, L-leucine), Natural Flavors, Inulin (Chicory Root), Potassium Citrate, Stevia, Caffeine, Ascorbic Acid, Butyrate.

  • Caffeine and caffeine free. Comes in a tub, or in single serving pouches.

    Best Review: Per Amazon “So glad I can buy this here in a pinch. I can not live without my Keto OS Chocolate is devine and helps me stay on track for my ketosis. Have lost 45 lbs with the help of KETO 0S”

    Most Critical Review: Per Amazon “It might work but I could never get past the taste.”

    Keto//OS Orange Dream – Beta Hydroxybutyrate, MCT Powder, Natural Flavor, Malic Acid, Stevia, Caffeine, Ascorbic Acid.

  • Caffeine and caffeine free. Comes in a tub, or in single serving pouches.

    Best Review: Per Amazon “The product works great when going fully Ketogenic. That said there are major issues with delivering this in a timely manner and therefore it should be removed from Amazon Prime as it has never been delivered on time. Change this and I will happily take it up to 5 starts.”

    Most Critical Review: Per Amazon “Used this for 6 weeks every day. I can’t say I saw the benefits that others have listed, but everyone is different. I can see it being a big benefit if you are doing the ketogenic thing and this is a supplement to push the process.”

    Keto Kreme – MCT Powder, Coconut Shortening Powder (C8, C10 and C12), Ceylon cinnamon and Stevia.

  • Pruvit advertises this product as a more efficient option to Bulletproof Coffee (their opinion, not ours). The blend contains coconut butter, ceylon cinnamon, stevia, and of course MCTs. You can learn more, here.

    Best Review: Per Amazon “it is great addition for a ‘bullet proof’ coffee in the morning. I split the pack in 1/2 and drink 1/2 packet with my first cup of coffee and then the next 1/2 pack with my 2nd cup of coffee. I often add heavy whipping cream to the coffee also. Keeps me full and not hungry and ‘fat fasting’ for several hours. I wouldn’t be without it. It is definitely expensive buying it from amazon. I buy from the company and it is less than a starbucks would cost and better for me. (ketocain . com)”

    Most Critical Review: Per Amazon “This product simply does not do what it claims to do. I have been doing Keto for a month. I test my blood ketone levels every day in the morning, I test my breath ketone levels every night before sleep. I have a very solid baseline of where my level of ketosis is. I bought the 3 pack of these items as well as the three pack of the orange flavored packages, tried them as directed, and found absolutely NO DIFFERENCE in my blood or breath ketone levels. Never trust the urine keto sticks as they as they are very unreliable. (Obviously) Save your money, don’t get suckered like I did.”


    We’ve previously reviewed KetoCaNa and noted it’s endorsements from the likes of Dr. Dom D’Agostino and Tim Ferriss. Since our last article regarding the product, its manufacturer, Keto Sports, has introduced a new flavor besides the traditional “orange” – “strawberry lemonade.”

    KetoCaNa is a powder-based exogenous ketone product that is mixed with water. Each serving (19 grams), provides 11.7 grams of Beta-Hydroxybutyrate, stevia, citric, and natural flavoring.

    Best Review: Per Amazon “This stuff is GOLD, people !!! Quit whining about the taste, suck it up and shoot it … IT WORKS.. what more do you want? CAKE ? I mean, seriously .. people take shots of tequila all night long.. Why ?, well it sure ain’t for the taste.. because of the way it makes them FEEL .. IT WORKS … Yes, it’s pricey.. but GREAT Products usually do hold a bigger price tag.”

    Most Critical Review: Per Amazon “This stuff is just terrible to drink. I have to mix the 2 cap fulls with a whole powerade zero to choke it down. It is sooo salty. The energy it gives is nice, but know that if you are using ketosis to lose weight this will stunt the production of ketones through fat breakdown. Can we somehow put these into a capsule?”

    Keto Force

    Keto Force is a liquid ketone supplement that provides the user with a dose of the ketone body Beta-Hydroxybutyrate in the form of sodium and potassium salt (ketone salt). After taking a serving of Keto Force (30 cc), Keto Sports suggests you’ll experience increased levels of blood ketones in approximately 2.5 to 3 hours after ingesting a dose.

    Keto Sports also suggests that you take Keto Force with an acidic beverage, due to its pH alkalinity.

    Best Review: Per Amazon “You can feel this product working immediately. For me, I can feel my body eating its own fat. The taste is definitely an acquired taste and it is recommended to drink with an acidic drink like lemon water but I just take 3 caps right when I wake up and then either go to the gym or eat breakfast right after. I don’t have any appetite all day and since I started 3 days ago I have unconsciously skipped lunch everyday.”

    Most Critical Review: Per Amazon “Has basically the same active ingredients as KetoSports KetoCaNa (10.75oz) The Original Exogenous Ketone Supplement but unlike the powder (which tastes great) it tastes awful…to use it up I have resorted to going 50-50 with the great tasting powder…live and learn!”


    This is the first time we’ve featured this product, and we’re very excited, because one of the leading developers is none other than Dr. Dominic D’Agostino: one of the pioneer researchers in the physiological effects of ketosis!

    kegenix ketone supplement

    You can learn more about Dr. D’Agostino’s research here!

    The Kegenix drink mix comes in three different flavors, pomegranate, lemon twist, and wild berry. You can choose a 15 day supply, or a 30 day supply. Each box comes with packets that you simply mix with water. Per Kegenix’s website, each packet contains the following:

    • Proprietary Ketosis Supplements
    • MCT
    • Vitamins and Mineral Supplements
    • Green Tea

    Best Review: Per Amazon “”Wow. Why is it so expensive?” is what I thought when I saw Kegenix on Amazon and reading the reviews, I wasn’t really sold. I had read reviews from ketogenic diet websites and I figured I wouldn’t need it as long as I strictly kept my fat-protien-carbohydrate ratio correct. However, on my second day of changing my diet, I started getting a massive migraine and I was nodding off at my desk at work…

    I wouldn’t believe it was keto-flu, so I took two ibuprofen and chugged on. The next day, the headache was back and i was still tired. I splurged and got Kegenix, checking the website first, of course, to make sure the price on Amazon was correct. It’s been a week since taking Kegenix and I don’t have headaches anymore, I’ve lost about 2 lbs, and I don’t nod off at work. It might also be in my head, but I seem to have more energy. Yes, it’s expensive and it definitely put a ding in my wallet, but I figure it’s a little under 5 dollars a day and I don’t drink energy drinks anymore so it evens out. Plus, the headaches and fatigue is definitely gone. I will take the one month supply and gauge how I feel afterwards. If I need it later, I will continue.

    The Kegenix website says it’s good for when you fall off the keto-wagon. I’ll probably be needing it with the holidays coming up, it’s hard for me to resist pumpkin pie. I haven’t tried the other flavors and one of the other reviewers said it tasted like baboon sweat, but I actually like the flavor of Wild Berry and I think it tastes better than most Monster energy drinks. The Kegenix website has recipes to try out (the coconut oil fat bombs are really easy and super tasty) and other help. There’s also a daily motivational email that Kegenix sends out. The only complaint I have is the first email from the Kegenix motivational website messed up either the script or they send a old form email and the date was wrong. I will update the review after a month.”

    Most Critical Review: Per Amazon “It does what it promises, it does put you in ketosis in an hour. I had already been on keto diet for 6 mos and already lost 65 lbs on the diet. I ate exactly the way I did before and took kegenix every day for 2 weeks. I actually gained 4 lbs. I stopped taking it. Maybe it’s the 11.5 carbs per serving? Not sure, but doesn’t work for me. I stopped using and started losing again…..”


    InstaKetones comes in only one flavor, Orange Burst, and is a powder-based ketone supplement that can be mixed with 8 ounces of cold water once a day. Each serving of InstaKetones (17.5g) contains 11.7g of BHB (Beta-Hydroxybutyrate), an amino acid blend, calcium, sodium, citric acid, orange extract, and Lou Han Guo (Monk fruit).

  • Provided in caffeine and caffeine free forms.

    Best Review: Per Amazon “Love it and the taste is fine. What people need to understand is beta hydroxybutyrate is not supposed to taste good. I have tried several other BHB supplements and this one tastes fine. Much better than some of the other options.”

    Most Critical Review: Per Amazon “Horrible taste, Much better alternatives available. Could not mask the taste with adding anything and the aftertaste seemed to stay with me for days.”

    KGX Boost

    This last product differs from the others in that instead of being a supplement you mix with a drink, it instead serves as a spray that you take orally six times a day (per their website). Dr. D’Agostino was also a major guide on developing this product, developing its patented blend of ketones to assist with energy, focus, and avoiding cravings.

    Best Review: Per Amazon “It works. Enough said. Great Product. 30 doses for the price, you can’t beat it. Tastes great too. No aftertaste. I haven’t touched my preworkout since picking this up. I spray directly under my tongue before swallowing I feel that it hits me faster.”

    Most Critical Review: Per Amazon “I’m pretty bummed because I though Boost may improve my Blood Ketone level. I wasn’t expecting a huge jump or boost in my levels using a Blood Ketone Meter but thus far after 4 or 5 experimental tries I have seen zero improvement. I eat a Keto diet and although my levels are rarely very high I probably average being around 0.7 mg/dL. Experimenting with Boost hasn’t improved even in small incruments. I have even over sprayed the product with zero improvement in my levels. Truly bummed!”

    These ketone supplements won’t solve all of your Ketogenic Diet needs, but they will be a major asset for you as you adapt your life to the fat burning lifestyle. Being able to get into or stay in ketosis isn’t always easy in our fast paced world, but being able to simply mix or spray of exogenous ketones into your system means not having to make up an emergency meal every time you need fat to burn.
