        To energize you through the afternoon slump.


        To fuel your body with ketones.

        Starting Keto

        To combat keto flu symptoms.

        Restarting Keto

        To ease your transition back into ketosis.

        Introducing New, Delicious Exogenous Ketone Base

        We spent six months and five iterations reformulating our original Ketone Base formula to make it even better without adding any sugar, artificial ingredients, or fillers -- because we'd never do that.

        Perfectly Sweet with No Bitterness

        We used monk fruit to give it the perfect balance of sweetness and eliminated the usual bitterness of BHB salts. The result? Delicious Exogenous Ketones that taste amazing just mixed with water.

        The Energy Boost You Need

        Mornings, afternoon slumps, before workouts, for mental clarity, maintaining high energy levels, and to beat the dreaded "keto flu." Exogenous ketones act as fat fuel for your keto lifestyle.

        What’s inside?

        Every ingredient pulls its weight.

        • BHBs

          Beta-hydroxybutyrate (BHB) is a naturally occurring molecule called a ketone body. It is one of the main molecules that provides your body with energy in the absence of glucose. 

        • Natural Flavors

          Natural Flavors are oils, oleoresins, extracts, or flavor components derived from natural sources like spices, fruits, vegetables, herbs, etc.

        • Monk Fruit

          Monk fruit is a natural sweetener extracted from the monk fruit plant. It contains mogrosides, which contribute to the sweet flavor and may have antioxidant properties.

        • Stevia

          Stevia is a low-calorie sugar substitute that comes from the Stevia rebaudiana (Bertoni) plant.

        Press reviews

        "They have excellent supplements that really help boost energy and get you over the hump when you first get into keto. Exogenous ketones help you get over that hump. Their chocolate one, in particular, is my favorite!"

        - Joe Rogan

        "This is a type of ketone metabolite—an energy molecule. Your body forms beta-hydroxybutyrate (BHB) when it’s breaking down and burning fat; people in ketosis tend to have higher levels of BHB. It would be especially useful when you’re starting keto to ensure a smooth transition."

        -Reader's Digest

        "Trying out the Keto Diet? Here is what you need to get started."

        How we use Exogenous Ketone Base

        As I start my work day, I mix up a little exogenous Ketone Base and MCT Oil Powder to fuel my brain.

        Anthony Anthony, our CEO

        I like my coffee strong so I add coffee ketone base to my Instant Keto cup every morning to give it that boost of flavor and a hint of natural sweetness.

        Rajiv Rajiv, our Director of Paid Advertising

        Since I also like to avoid caffeine in the late afternoon, I mix 1 scoop of Keto Base with water to power through the slump.

        • Do I have to be on a ketogenic diet to take Keto Base?

          No, but you will get the best results when taking them in conjunction with at least a low carb diet.
        • Does Perfect Keto Base put me into ketosis?

          Perfect Keto Base temporarily increases blood ketones (2-3 hours) but it is not a magic supplement that puts you into ketosis long-term.
        • Are the ketones in Perfect Keto Base the same ketones that my body produces?

          No, the ketones are slightly different.
        • Does Perfect Keto Base cause weight loss?

          Perfect Keto Base does not directly cause weight loss. However, it can aid in your weight loss journey by giving you the physical energy to exercise effectively and the mental energy to make great food choices. Keto Base keeps your energy high and your cravings low.
        • How is Perfect Keto Base different from Perfect Keto MCT Oil Powder?

          The difference is that our Keto Base puts ketones directly into your blood stream whereas MCT Oil stimulates your body to produce ketones naturally.

        Does what it says

        I use it as an afternoon pick me up, or to extend my fast in the morning, just like it says. I'll put it in coffee or a shake, but it does have a taste that is somewhat bitter. Overall good experience

        Can't handle the taste

        I simple just dont like the taste. I have tried several times thinking I just had to adjust and I cant.

        Has changed slightly, but still good.

        This is going to seem like a bad review, but overall this is a great product and I will continue to use it until I no longer see results or until it no longer exists. So, if you are considering it, go ahead and try it. I bet you will be happy with it. However, I can't give this a 5 star rating because it just isn't quite the same anymore. I know that they have gone through a few iterations of the formula over the last couple years, which has caused the taste of it to change a bit. I have tried all the flavors, but the peach. The chocolate is the only one I can drink now without gagging. I miss the ketones with MCT oil. They were so yummy in the vanilla flavor. Although I will say that I appreciate the much lower calories as I take it every night before bed. The other bummer, but not enough to stop taking it, is that this last iteration doesn't seem to help "keep things moving" like the last two did. At least with the chocolate flavor. The caramel and coffee seem to work still, but I can't stand the taste of those two. I have always used the ketones to help stave off constipation due to being keto and having chronic constipation all my life, but now all the flavors make me gag except the chocolate and it doesn't seem to do the trick like it used to. It still helps enough with everything else, that I feel the benefits outweigh everything else.

        Taking time to adjust

        This is a great idea , and I was tempted to dive right into using it, but I heeded the caution you recommended and started with 1/4 of a scoop. I’m so glad I did! Then I tried 1/2 scoop. I can’t seem to get beyond a 1/2 scoop every other day. And if I’m scheduled to be out of the house I don’t use it at all! My body really reacts to it so I don’t stray far from a bathroom! And yet I want to keep using it, I like the ‘feel’ of ketosis! I’m on a multi step loss program under my doctors care and am losing weight. This, I believe, is helping in that endeavor. If I ever get to the point I can take it daily, I’m certain it will be valuable in my wt loss program!

        Curbs my cravings

        I have ordered 10 or more of these over the past year because of the taste, quality and how well it works for me
