KetoneAid Ke4 Ketone Ester Concentrate | Not a Ketone Salt, No Sugar, No Caffeine | Exogenous D-BHB Ester | 12 Serving Per Bottle (3 Count)

#1 it works. #2 The CEO, Frank LLosa is accessible to customers via phone or Facebook (KetoneAid), and he is a no BS (honest and knowledgeable) professional. I have called him several times with questions. So yeah, customer service is second to none. #3 I have consumed 6 KE4 bottles to date (with many more to go) in support of both standard of care, and non-standard of care medical protocols (for mRNA signalling benefits and normal cell protective) reasons (NOT diet weight-loss and NOT physical athletic performance). KE4 has always delivered measurable results as advertised and expected (I measure Ketones/Glucose with a KetoMojo meter). I am normally Ketogenic, and KE4 is there for me when my Ketone levels fall off due to various reasons. My limited research and understanding on KE4: KE4 Converts directly into usable chemical energy also supporting various cell signalling (as per a growing volumes of animal and Human N=1 research -- which shows Ketones protect cells, supports OxPhos energy metabolism, and enables medical protocols designed to suppress normal cell glycolytic pathway functions leading to pyruvate/lactate production). KE4 (BHB) also supports improved cognition as-well-as motor function (why most people take it). Taste: It tastes like a chemical fuel. I personally don't have an issue with the taste, but I can understand why babies, girls, and girly men would. Its really not that bad -- but I'm not using it casually as a diet aid either. If you consume KE4 subliminally (hold it in your mouth and under the tongue for an extended time, before swallowing) it should get absorbed faster into the blood for immediate use. Price: While it appears the price is high, it is very reasonable for what it actually is (non-racemic ester) and for what it does (converts directly into AcetylCOA). First, its 100% bio-available -- 100% -- (not 50% or less-- like many/most BHB-Salt based products). Second, BHB ester has been the chemical gold standard for some time -- used in research labs only -- it was unavailable commercially -- and it was price prohibitive: priced in the thousands of dollars just over a year or so ago. KE4 is the real deal, now available commercially for NOT thousands of dollars. Most folks just don't get this. How does KE4 provide 100% bio-available instant ketones? My understanding (and I am not a chemist): I believe this to be an enantiomerically pure ketone ester (non-racemic). (just google it) Racemic BHB products have a left and right side molecule -- thus providing 50% or less available BHB for direct utilization. In other words, KE4 BHB Ester is fully bio-available, so you are receiving full value for the price. You can meter the amount you need for whatever your purpose is. KetoneAid even gives you a little measuring tube with the three container pack. With other racemic BHB-Salt products (right and left hand molecules) only one half (or less) of the ketones are bioavailable. How does KE4 BHB Esters work? This is very important for my personal medical (non-diet/non-athletic performance) application: I believe KE4 is a organic BHB (beta-hydroxy-buterate) ester and it is NOT related to a salt. In the body the liver (primarily) creates ketone bodies as needed (fasted state): Acetoacetic Acid, BHB, and acetone. The energy in our body at the cellular level is ATP. ATP (adenosine triphosphate) powers all mechanical and nerve functions in the body. ATP production (creation) by key organelles (called Mitochondria), found in most cells requires a fundamental chemical building block (Acetyl-CoA) to be available in order for the oxygen phosphorylation chemical process to occur, thus efficiently generating ATP. The free availability of AcetylCOA is also an important signalling state, which is key for my condition, but I will not explain that mechanism in detail here. BHB freely converts to AcetylCOA with Acetoacetate, supporting the mitochondrial production of ATP via the citric acid cycle (Krebs Cycle). KE4 is an ester, so its presents within the body converts directly to usable energy in various tissues. Because BHB esters also pass the blood-brain barrier they will be utilized for energy by the brain (the largest consumer of energy in the body). The down sides of KE4: Because KE4 is not a salt (calcium, potassium, magnesium) it doesn't supplement these electrolytes if your in a fasted state. Having said that, of the 60ml in each small container, 30ml is BHB and 30ml contains beneficial supplementation like Taurine (calcium modulator and anti-oxidant) for cardio support, etc.

Honestly I started taking this stuff after researching TBIs and recovery. I had brain fog post concussions and a few physical injuries to recover from. PT wasn’t doing it for me so I took matters into my own hands. I’m a few years into the story, so this is a couple of years worth of review. It depends on when I take KE4 whether I feel the effects immediately or realize afterwards how much it helped. If I take it first thing in the morning, I can feel my brain kick in and I’m ready to be “On It!” for work much like what coffee promised me but doesn’t seem to deliver as consistently. If I take it before my workout in the evening I don’t feel the gears kicking in like in the morning, but I can push through more of my workout or lift more weight (go one set up in dumbbells or finish a set I didn’t think I had in me). That’s where the gains are, just getting that little bit more in. This isn’t anything like steroids or even a stimulant pre-workout. It’s subtle, but with consistent use, especially combined with electrolytes and creatine, you do get some pretty incredible results - both physical and neurological. Other things I’ve noticed are when I take KE4 with electrolytes (my LMNT powder) I can either ease or get rid of migraines, and a capful seems to help me get better quality sleep. I don’t understand how something can help me sleep, ease a headache, but also help with turning my brain on and getting results in the gym. I’m happy to continue getting these kinds of results. Since the TBIs and the physical injuries, I got into the keto diet as well. This stuff helps to amplify the effects of the diet when my body gets a little too adapted and efficient with the diet alone. The only thing I dislike about it is the taste. I’ve never been a fan of cherry but I will gladly down a cherry flavored capful or two for those kinds of results.

Takes some getting used to the taste Great effects Needs better pour

Do not even bother with this. It doesn’t live up to its own or independent hype. I followed the one capful directions for six days, took it on an empty stomach. I fasted for two to three hours after taking it. I did not test for ketones first thing in the morning because of the Dawn Phenomenon. I tested two hours after taking it, and in the afternoon and evening. I was already in light ketosis (1.08 to 1.2) several days before I started Ke4, and have been largely for 10 years prior, because I spent 3 years on the keto diet, and 7+ years Carnivore. Started my 8th year Jan 1st. I wanted to see Ke4’s impact. Ke4 did little or nothing to increase my ketone levels. In fact, a couple of readings went below 1.x to .55 or .63. It did not create any sense of increased energy or mental clarity. The taste is absolutely awful. I chugged it down in a little water. At least it’s not sweetened or flavored. Too bad they don’t care, won’t read this, and I can’t get my money back. I had much better results with keto salts shots. At least they maintained my ketone count, and didn’t lower it. After simply stopping this product, my ketone levels went up to 2+. This product is a sham.

The jury is still out on KE4 for me. I've been reading that a large number of procyclist and marathon runners are now using these, so that's worth following to see what they find over time. I bought this to use when I was on the keto diet. I used ketone esters when biking, running, and doing demanding manual labor tasks around the house as after starting this diet my body was incapable of keeping up with ketone production necessary to keep me going at a level I was accustomed to on a standard diet. It was very frustrating how fast I would tire. I started with the KetoneAid Shots (2oz ready-to-drink bottle), which worked incredibly well. I was definitely working out in a fuel-deficient mode because within about 5-10 minutes of drinking a 1/2 shot I felt like a turbo had kicked in! The burning in my legs when I pushed up a hill biking or running was gone and I could sustain such an effort much longer. Anyway, those bottles are $8 a piece for 2 shots ($4/shot), so I thought I could get a better deal using the KE4, which I figured I could get down to ~$2.50 a shot if I bought from the manufacturer in bulk. Unfortunately, even mixing my own "shots" with the KE4 using comparable ketone ester amounts, I didn't feel the turbo as much (I switched back and forth between KE4 and the shots a couple times to be sure). KE4 definitely helped, but I seemed to somehow get more from the pre-mixed shots. Note this was purely my subjective perception of the impact it had on my performance. I wasn't doing time-trials or anything to get any form of data (though that would be really interesting to do!). Probably not surprisingly, the longer I did keto, the better my body became at making my own ketones and keeping up with the demand during activity. So again while these definitely helped, the turbo-boost effect became less noticeable over time. I continued using them when I finished up with keto (though still eating lower carbs). I've been testing my blood ketones and am definitely out of ketosis (per published metrics, ketones < 0.5mmol/L) and I'm not sure how much difference adding ketone esters makes. I think it still helps a little, but I'm not racing or anything so the cost/benefit ratio is getting too high for me and I've stopped using it. For someone starting the keto diet, especially if you are very low carb and going after a therapeutic level of ketosis who wants to boost their energy for workouts (or just working), I highly recommend these. I was very happy with the results of doing keto and plan (at least for now) to do the diet at least once per year. So I plan to have these on hand next time to help me maintain my activity level through the early days (at least) of the diet. If you are racing/competing I suspect these can be useful (read up on the pros using it), so if you need that edge the cost/benefit ratio may be worth it to you. You probably should research how the body utilizes these, if you get the desired benefit on day-one or if you need to "train" your body over time to better utilize ketones. It's something that's on my to-do list, just haven't gotten to it yet.

I’ve tested a lot of ketone products with athletes, executives, and high-performing clients. My work depends on it. KetoneAid KE4 is the one that consistently stays in my core protocols. It’s a true ketone monoester that delivers pure D-BHB the same ketone your body naturally makes. It raises blood ketones quickly and reliably without the heavy mineral load found in most ketone salts. Many salts contain mixed forms of BHB and require large amounts of sodium or potassium just to get a modest effect. KE4 delivers a higher amount of the usable form in a smaller volume. In practice, that means clearer thinking, steadier energy, lower appetite, and reduced perceived effort during training. For athletes, I use it before key sessions or in fasted states to maintain output without a crash. For executives, it supports calm focus and sustained cognitive performance without stimulation. When you look at cost per effective serving not just price per bottle KE4 is actually more efficient because it delivers more active ketone per dose. It’s clean, predictable, and powerful. That’s why it’s a staple in my protocols.

KE4 Provides help with Dementia/Alzheiemer’s There are over 5.8 million people suffering with some form of dementia in the U.S. and over 747,000 in Canada. (Alzheimer’s is the most common form). While there are currently six drugs, they don’t work for everyone and there can be some side effects that stops their usage. All of us are told that there’s nothing else out there for looking after our loved ones who have dementia. Thankfully, there is help with ketone based products, including the most concentrated form, the ketone ester, called: KE4. For a thorough history of the use of ketones as well as the research that has taken place one excellent book is The Complete Book of Ketones by Dr. Mary Newport. It’s important to have this background so you don’t just have to rely on testimonies. In our case, we use three ketone products daily and this has provided stability and calmness for most of the day. Then almost two months ago I began to give KE4 to my loved one and there were some very surprising and helpful results. There have not been any side effects. Here is a shortlist of both the dose and what has taken place so far (I have kept a careful daily diary): Dose: We began giving the ketone ester Feb. 17/22 (1 teaspoon with 1/3 cup of pomegranate juice). After four days began noticing changes. Mar. 12 I began giving her 1 ½ teaspoons of the ketone ester with ½ cup of pomegranate juice. April 3/22 I began giving 2 teaspoons of the ketone ester with 138 ml of pomegranate juice (= ½ cup + 1 tbsp and 1 tsp) Sleep and hand tremors improvement Waking up in the middle of the night has almost been phased out. As of April 9/22 it has only happened twice in 43 days (once for 2 hours and another time for about 10 or 15 minutes). This is possibly the most important area since once a loved one no longer sleeps through the night it begins to destroy the health of the caregiver and they may need to place them in a care home. Radically decreased running out the door While this used to take place 2 or 3 times a day it now has only happened once. If I would not follow after her quickly I would lose sight of which way she went. I am so thankful for this change. Eyesight improvement in one area She was now able to put the key into the key hole at least once on most days beginning today. Her eyesight had gone down so much from the disease that this is quite amazing. Guitar She has been able to find the first chord by herself and then play several songs Thoughts – While terrible thoughts would come into her head and cause upset, she has begun to have happy thoughts that cause her to laugh. Humor She now responds to humor and more recently has begun to show humor herself. Fine for the entire day She has had two days recently where she is fine for the entire day. There were no upsets or stressful times. Needless to say, I am very thankful and happy that there is something to bring help to our situation right here and now. I should note that in spite of the improvements, there is no evidence at this point that it can slow down or stop the progression of the disease. Future needs: A breakthrough is needed to neutralize the challenging taste of the ketone ester and to bring down the cost so many more would be able to benefit from this special product. If you read the above book I mentioned you will find that people with various chronic diseases have been helped with KE4 not just those with dementia.

Wow, I LOVE this stuff! Granted it tastes like death but it is a bringer of life. It provides a great boost of clean energy, especially mentally, bordering on a runner's high and without the unclean, jitter effect that can come when caffeine crosses that line from energy booster to energy erraticness. It's definitely pricey, and you've got to be careful to not take too much, too soon cause it could upset your stomach as it's not something it's experienced before, and 1-2 capfuls will raise ketone levels plenty, so the more isn't necessarily the merrier. Overall, despite its hefty price tag, I say you can't beat it when it comes to the type of energy it provides, and the appetite suppressing effect to limit hunger cravings. I HIGHLY recommend! 👍
