Top-Rated Exogenous Ketones Supplements in 2020

If you’re reading this, you’re probably either on or considering starting a ketogenic diet. It also seems likely that you’re looking to supplement your diet with exogenous ketones.

Or, perhaps you’ve been hearing all about the new ketogenic diet that your friends and family are on and you want to try it, too. Or your just wondering what all the fuss is about, and if you’re going to get into it, you might as well do it right.

Well, you’ve come to the right place. We’re going to first define what a ketogenic diet is, followed by reasons why supplementing your diet with exogenous ketones might be a good idea.

First, let’s talk about ketogenic diets.

What is a Ketogenic Diet?

Ketogenic diets, or, as their more commonly and simply referred to, “keto”, are centered around returning your body to the state that the human body existed in a long, long time ago. This is accomplished by encouraging your body to burn fat for energy instead of carbohydrates.

The body will typically take the carbs that you eat and convert them directly into glucose, which fuels your body’s energy. On a keto diet, however, you’ll eat very, very few carbs, thereby requiring your body to find energy elsewhere, which is where the high-fat portion of a keto diet comes in.

At least 70 percent of what you eat on a ketogenic diet will be fats. Which sounds great, until you remind yourself that carbohydrates will make up less than 10 percent of your diet. In other words, you’ll have to be pretty choosey about how your getting all of those fats — lots of cheeses and things of that nature, and not necessarily donuts and pizza.

The rest of your diet, which is about 20 to 25 percent, will be made up of proteins. You won’t need to be quite as cautious with proteins as you are with carbs; for instance if you’ve heard that eating too much protein might activate a process within your body that could kick you out of ketosis, well, that’s not true.

Instead, be smart about the fats and proteins that you’re consuming and keep the carbs to a bare minimum. Then, your body will reward you by exclusively burning fat for energy, allowing you to build muscle and keep off those unwanted pounds of fat.

Ketosis is completely natural; it’s the mode that your body would enter into if you were literally starving. In effect, you’re teaching your body to behave that way by more efficiently processing nutrients and deriving energy from excess fat cells.

What are Exogenous Ketones?

If you’re sold on starting a ketosis diet or are already knee-deep in one and want to enjoy the best possible results, then exogenous ketones might be just the products for you.

Exogenous, of course, just means that something is developing from an outside factor, meaning that the ketones that you’ll be essentially injecting into your everyday routine and diet are supplements, and not directly from natural food products.

As far as ketones go, it’s important to note that your body has three different types of ketones that it uses: acetoacetate, acetone, and beta-hydroxybutyrate. The latter is the version that most supplements are based off of, as it allows the ketones to not be bound to any other compounds and flow freely in your blood, allowing your tissues to use said ketones much more quickly.

There are three types of exogenous ketones that you can find on the market: ketone esters, ketone salts, and ketone oils. You’ll also want to look out for imitation products that may claim to use keto but don’t promote their actual ketone levels. More on that later.

Ketone esters aren’t all that popular, as this raw version of ketones tastes bad and can cause unpleasant gastric issues. With ketone salts, the ketone is able to provide rapid energy and much better taste. And with ketone oils, you’ll find products that are much more about long-acting energy instead of short-term bursts.

Why Take Exogenous Ketones?

So, now that you have the backstory, let’s talk about why exogenous ketones might be a match for you.

First of all, committing to and sticking with a ketogenic diet is no easy task. It’s a restrictive and demanding diet that isn’t even always feasible for the average person to maintain. Therefore, adding exogenous ketones to your routine to help you stick to those guidelines, and if you slip-up — carbs are delicious, after all — then these supplements can help push you back into ketosis much more quickly than if you have to essentially reboot your diet.

Also, if being on a keto diet is impacting your energy, which is a common problem for people that are new to the diet, then many of the supplements on this list can assist with a short-term energy boost while keeping you in a state of ketosis. No worries about drinking the wrong energy drink that messes you up; just get an energy boost from a keto-friendly supplement.

Some athletes who are attempting a ketogenic diet may be forced to consume more carbohydrates than is ideal as they’re working out, so exogenous ketones could be used to add ketones to your body that can help those folks power through longer workouts.

There you have it. There are several reasons why people choose to take exogenous ketones, and if you find yourself nodding along to any of the above paragraphs or want to find yourself in that boat in short order, than be sure to take a hard look at the below products.

Without further ado, let’s run through the best exogenous ketones supplements on the market today.

  1. Perfect Keto – Best Exogenous Ketone Supplement

Perfect Keto is an all-natural exogenous ketone supplement that uses monk fruit extract in place of sugar, ensuring that there aren’t any added calories or a spike in blood sugar. Instead, you’ll enjoy a boost from an extract that is much, much sweeter than sugar.

Many exogenous ketone supplements have filler ingredients to complete their respective profiles, which will often be the cause of a bitter taste. Instead of falling in the line with their competition, Perfect Keto tastes great and will help you in your quest to achieve ketosis.

And as if that wasn’t enough, Perfect Keto includes essential minerals such as calcium and magnesium to enhance the supplement. Also included: beta-hydroxybutyrate, which is a compound within your body that acts as your body’s ketone supplier when blood glucose is low. It’s the emergency compound that kicks in when necessary, but in order to help your body reach and maintain ketosis, Perfect Keto has it included in its fantastic cocktail of ingredients.

Perfect Keto can be taken up to three times per day, ideally on an empty stomach. Each container contains 15 servings, and the product can be purchased in a variety of flavors including chocolate, coffee, peach, and vanilla.


  • Monk fruit extract is a healthy alternative to sugar
  • No carbs, gluten, or dairy
  • Tastes great, lots of flavors to choose from
  • Includes essential minerals


  • If not taken on an empty stomach could cause some mild stomach discomfort


  1. KETO//OS Exogenous Ketones

One of the keys of keto diets is feeling full enough on fats and limited proteins while resisting the temptation to fill out your day with carbs. Remember, carbs can only be about 10 percent of your diet at most, so it can be a challenge to truly feel full — especially if you’re working out at a high frequency and intensity.

KETO//OS is a supplement that is ketone salt-based and geared specifically towards helping to satiate your appetite, as well as assist in weight loss through consistent ketosis.

Weight loss is encouraged by satiety, of course. But that’s not the only benefit that KETO//OS provides. It also helps to balance your blood sugar, which only serves to have a positive effect on appetite and overall health. It also helps with alertness and increased attention and focus while helping you sleep better at night. Assistance with your gut health and digestive system is yet another added benefit.

Ingredients include caffeine, stevia (a natural sweetener), MCT powder, the essential amino acid l-leucine, l-taurine, and beta-hydroxybutyrate, which is your body’s natural compound to getting you into ketosis.

There are multiple flavors available, including chocolate swirl and orange dream. Each order comes with 15 packets, and the recommendation is to start with only about a half of a package per day but that can be increased to a full pack per day depending on the person.


  • Gluten-free
  • Assists with suppressing hunger and therefore helps greatly with weight loss
  • Variety of great-tasting flavors


  • Some added sugar
  • Some flavors include caffeine

  1. Zhou Keto Drive

This product from Zhou is termed as a “BHB” product, which is short for the aforementioned beta-hydroxybutyrate. As a reminder, BHB is the naturally-occurring compound already in your body that kicks in to place your body into a state of ketosis. For those of us who want to achieve this state regularly and stay there, it’s important to supplement the BHB within our body.

Zhou Keto Drive not only supplements your body’s existing beta-hydroxybutyrate, but it also assists with overall endurance, mental performance, and energy, as well as contributing to appetite suppression.

Keto Drive achieves this while being caffeine-free, carb-free, and sugar-free. (There are some versions of Keto Drive that include caffeine; just be sure to choose the flavor that fits your needs best.) It can be mixed to virtually any cold beverage, and while the orange mango, matcha lemonade, and black cherry flavors are perfect with cold water, feel free to execute some trial and error with your other favorite liquids.

Speaking of the taste…several of the other keto supplements on the market struggle with taste, as ketones typically don’t taste very good on their own. But Zhou went out of its way to ensure that the delicious flavors of Keto Drive kept their customers coming back.

Ingredients of Zhou Keto Drive include various versions of beta-hydroxybutyrate, including sodium, calcium, and magnesium. There are approximately 16 servings per container.


  • No carbs or sugar
  • Can purchase with or without caffeine depending on flavor selection
  • Helps overall endurance, energy, mental performance, and suppresses appetite
  • Three flavors to choose from


  • Heavy focus on BHB without many ancillary ingredients and benefits

Sheer Ketones will get your body into ketosis quickly, as it’s designed to raise your blood ketone levels rapidly while helping you burn fat and increase your overall physical performance.

Sheer’s supplement is another beta-hydroxybutyrate (BHB) salt-based product that assists your body’s production of BHB and adds to its supply. The physical performance and energy boost that it provides will help you get the most out of your intense workouts.

Sheer Ketones is a non-GMO product that is completely gluten-free, carb-free, sugar-free, and naturally flavored without any additives. It’s a simple mix of ingredients that will get the job done without any of that extra stuff.

The blackberry lemonade flavor is delicious and easy to mix with anything, ensuring that you’ll have one of the best-tasting keto supplements on the market. There are about 16 servings in each container, and Sheer offers a 60-day, 100-percent money-back guarantee.


  • Non-GMO, plus no gluten, carbs, sugar, or other additives
  • Gets you into ketosis rapidly by supplementing your body’s BHB supply
  • Great-tasting product with a simple ingredients list

  1. Zenwise Keto-Lift BHB Supplement

As it indicates in the name, Zenwise Keto-Life BHB includes a special blend of beta-hydroxybutyrate (BHB) that will help you reach a ketogenic state without drastically cutting your diet as you’re working on your daily fitness plan.

Through an increase in blood ketone levels, Zenwise helps provide immediate energy that lasts for an extended period of time, increasing your clarity and focus along the way. That makes this product perfect as a pre-workout supplement, but it can also help with muscle recovery following workouts. Some simple trial and error should help you figure out which application works best for you.

Zenwise promotes their product as being enhanced with goBHB, which is an application of a ketone body of BHB that is unique to Zenwise. There are 11 grams of goBHB included, 874 mg of which is calcium, along with 9 mg of magnesium, and 1075 mg of sodium. This perfect mix will assist your body in getting into a state of ketosis quickly and effectively.

Weight loss is another aspect of keto diets that Zenwise Keto-Life BHB can help with, as the fatty acids included in the product can help suppress your appetite as well as act as your energy source as your body enters into a state of ketosis.

There are 16 servings per container, and Zenwise offers a 100-percent lifetime money-back guarantee.


  • Provides rapid increase in blood ketone levels
  • Assists in appetite suppression
  • Can function as a pre-workout or post-workout supplement
  • Includes 11 grams of goBHB per serving


  • Only one flavor available
  • Includes some additives, although it is vegan-friendly


  1. Keto Matrix

Keto Matrix is another keto supplement that relies on boosting your body’s BHB to achieve the desired result, but that isn’t the only thing that it does.

While the supplement includes the aforementioned goBHB compound, it also includes goMCT. MCT powder is a form of medium-chain triglycerides, as MCT oil is converted into powder so that it can exist in supplements like Keto Matrix. The MCT oil powder includes Caprylic acid and Capric acid, which are converted directly to energy.

Working together, goBHB and goMCT are a potent combination that will help you achieve ketosis, and along with that you’ll notice improved cognitive function, increased energy, and less hunger. Plus, in an effort to convey transparency, Keto Matrix lists the amounts of goBHB (8000 mg) and goMCT (4000 mg) per serving.

Keto Matrix has zero net carbs and zero sugar, so you’re only getting the best without any of the filler or any concern that you’ll fill yourself up with carbs, which is obviously a no-no if you’re on a keto diet. It’s also gluten-free and dairy-free.

The strawberry lemonade flavor comes in a container with approximately 15 servings and can be taken with or without food up to three times per day.


  • Includes both goBHB and goMCT, the latter of which includes Caprylic acid and Capric acid
  • Exact amounts of ingredients listed on label
  • Sugar-free, carb-free, dairy-free, and gluten-free


  • Only one flavor available


  1. Keto Function Ignite Keto

Ignite Keto is an aptly-named product made by Keto Function that says it will put you into ketosis in as little as 30 minutes by utilizing pure and instant ketones.

Ignite Keto’s unique performance blend is specifically designed to raise blood ketones, thereby improving performance both mentally and physically while helping you burn fat for fuel and increase your overall energy.

The formula has zero carbs, gums, fillers, or sugars, ensuring that you’re only treating your body to the best. The 12 grams of beta-hydroxybutyrate salts (BHB) in each serving augment your body’s existing supply and helps you function as a top-of-the-line keto machine.

Ignite Keto is easy to mix and will taste great in practically any liquid you choose to mix it in, including water, shakes, and more — even hot beverages are an option with this one.

There’s a 100-percent money-back guarantee from the company, too, so there really isn’t anything to worry about when it comes to trying it out. Plus, choose from three different flavors: caffe mocha, citrus splash, or wild berry, which comes with an infusion of caffeine. Regardless of flavor, there are 16 servings per container.


  • Works fast, propelling your body into ketosis in as little as 30 minutes
  • Free of cabs, gums, fillers, and sugars
  • 12 grams of BHB in each serving
  • Mixes with almost any drink, hot or cold


  • Limited additional benefits outside of fast-acting BHB


  1. Nutricost Exogenous Ketone Salts

Nutricost’s Exogenous Ketone Salts include 13 grams of beta-hydroxybutyrate per serving, ensuring that your body has ample BHB as you launch yourself into ketosis and do your best to stay there.

The product is completely non-GMO and gluten-free, and includes compounds such as calcium, magnesium, sodium, and potassium that only enhance the benefits that Nutricost Exogenous Ketone Salts provide your body. One of the primary reasons for these additions is to reinforce an electrolyte balance that isn’t always present in competitors, whose products will often have a diuretic effect on their users. It’s easy to drain your body of electrolytes while in ketosis, so this is a clear advantage that Nutricost has over other exogenous ketone products.

Like many of the other products on this list, Nutricost will help you with weight management and cognitive function, as well as assisting in the reduction of excess fat.

Nutricost offers the supplement in a variety of sizes, from a single, 500-gram bottle to a 30-serving container to three containers together for a total of 90 servings. You can enjoy a lemon-lime flavored product or choose to order it unflavored if you prefer.


  • 13 grams of BHB per serving
  • Includes elements such as calcium, magnesium, sodium, and potassium that assist your body in replenishing lost electrolytes
  • Can be purchased in a variety of sizes
  • Non-GMO and gluten-free


  • Only two flavor options: lemon-lime and unflavored


  1. Sports Research Keto Plus

Keto Plus from Sports Research is exogenous ketones supplement that is perfect as a pre-workout or afternoon pick-me-up, as its focus is largely on increasing your energy in rapid fashion — but without a crash that traditional energy drinks or supplements usually bring with them.

Keto Plus includes plenty of BHB, plus amino acids, chromium picolinate and prebiotic fiber. The supplement is not carb-free; while there isn’t much in the way of carbohydrates, this product aims to provide the same benefits of a keto diet without a complete carb restriction. That certainly can work, but be sure that the approach is right for what you’re looking to do.

Other ingredients include citric acid, calcium silicate, malic acid, and silica. Instead of sugar, Sports Research includes stevia and monk fruit, and there are also fruit and vegetable juices added for flavor.

Keto Plus comes in raspberry lemonade flavor, and each container includes 20 servings, which is more than most of the other options on this countdown.


  • Includes BHB, amino acids, chromium picolinate, and prebiotic fiber
  • No sugar, instead includes stevia and monk fruit
  • 20 servings per container
  • Provides ample and sustainable energy


  • Only one flavor option
  • Not an all-natural product



  1. Top Notch Keto Magic

Keto Magic takes a different approach than many of their competitors. Instead of packing the supplement with BHBs, they include a concentrated, smaller dose that won’t get in the way of natural fat loss.

While some exogenous ketone products are high in calories and high in sodium and include large totals of BHB and/or fillers (remember, BHBs are highly caloric themselves), Top Notch asserts that their research has found that more than five grams of BHB can actually inhibit your body from reaching ketosis. There are only four grams of the previously mentioned high-quality, highly concentrated BHB, plus two grams of butyric acid.

While your blood ketone levels will grow, your glucose levels will shrink. Low glucose plus high ketone levels will help you recover if you eat too many carbs, as you’ll be able to get back to ketosis relatively easily.

You can use Keto Magic in a variety of ways and at any time of day. For instance, it’s great as a pre-workout or to start your day, or even during your workout to ensure that you sustain energy throughout. If you’re choosing to fast intermittently to help you stay in ketosis, this is a fantastic supplement for that, too.

Along with all of the above benefits, Keto Magic will also help promote muscle growth and maintenance, as well as helping your body maintain an appropriate level of electrolytes, which our bodies are prone to lose if we stay in ketosis for an extended period of time. Inclusions to help replenish electrolytes include calcium, magnesium, sodium, and potassium.

Keto Magic comes in a berry lemonade flavor in a container with 15 individually-packaged servings of the product, making it easy for you to take the supplement with you wherever you go. It is also gluten-free, dairy-free, and non-GMO.


  • Has the perfect amount of high-quality, highly-concentrated BHB
  • Helps keep glucose levels low, which encourages your body to recover quickly if you consume too many carbs
  • Ingredients included will help to replenish electrolytes
  • Includes 15 individually-wrapped packages


  • Only one flavor option


Summarizing the list

Any one of the 10 exogenous ketones listed above would be an excellent option as you begin or continue (and hopefully improve) your journey on a ketogenic diet.

There are absolutely varying schools of thought in a few of the products, from high levels of beta-hydroxybutyrate to the supplements that keep that number below five grams. There are a few products that include several additional inclusions to assist with other aspects of your health, from electrolyte replenishment to keeping your glucose levels low.

But the majority of the details align with one another, including low-carb, low-sugar, and largely non-GMO products on the list. There were even a few all-natural options, too, which is always a good thing when you can manage to find them.

If you’re an athlete that occasionally ends up consuming too many carbs, then there are a couple of products on the list that will be preferred options as they will contribute to kicking you back into ketosis if you slip-up.

Final Thoughts on the Best Exogenous Ketones Supplement

When you’re working on selecting an exogenous ketone to supplement your diet and workout schedule, there are a few things that you’ll want to be sure and keep an eye out for.

First, and this is certainly the most obvious one, make sure the supplement that you are looking at is either carb-free, or at the very least, extremely low-carb. You can’t afford to let more than 10 to 15 percent of your diet be carbohydrates, and if you’re truly supplementing your ketogenic diet, then it would be counterproductive to do so with a supplement that features carbs.

Another thing to look at is the levels of BHB included. Remember, your body naturally produces BHB, and while it’s important to supplement those levels somewhat as you improve your diet, you’ll want to be sure to not over saturate your body with BHB, which could have a negative impact on the weight-loss and fat-burning side of things.

Also, if it’s coming down to it and you can’t decide between one or two different products, take a look at some of the ancillary benefits. For instance, some supplements include essential amino acids, or additional compounds such as potassium, magnesium, and calcium that provide “bonus” impact on your body.

Lastly, be sure to consult your doctor before making any drastic changes. Hopefully you’ve already done that before launching head-first into a keto diet, but if you’re looking at starting such a transition and taking any kind of supplement is part of your plan, it’s always best to check with a physician before taking the plunge.

Hopefully the above list acted as a nearly comprehensive guide as you begin your search for the perfect supplement. Don’t hesitate to do some additional research, however, and always be sure to study the individual nutritional labels yourself before making a final decision.

Happy keto-ing!
