## Description

This is the lowest cost ketogenic drink to reach 1mm blood ketone levels. Recommended by Dr. Mary Newport in her latest book Complete Guide to Ketones, and mentioned in the book Ketones. The Fourth Fuel.

Review: #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.
Review: I ordered KetoneAid KE4 and received it in a reasonable timeframe. The bottles in my order were the newer plastic bottles, and they were sealed well with no leakages. I typically fast intermittently, anywhere from 16-18 hours a day (I have done longer fasts before) and try to stay low-carb whenever possible. I have tried strict Keto but that doesn’t always work out for me. I’ve also used bib salts and other ketone supplements (from cheaper to more expensive — both salt pills and flavored powder packets). I was 15 hours into my fast on the first day that I took KetoneAid. I’d already had 2 cups of dark roast coffee (black) and plenty of water with electrolytes. I had also watched several of the FAQ videos on the KetoneAid website and Youtube channel, so I had some sort of understanding about how these ketone esters functioned. Apparently, I missed the video about ketone esters and caffeine, because I started with 1 capful (5ml) and had a VERY caffeinated rest of the day. If you’re a heavy coffee/caffeine drinker, I would recommend dialing back on that while you figure out how the ketone esters will affect you. I started the next day with 5ml (1 capful) first thing in the morning, which helped to give me some subtle mental clarity. I did have a cup of coffee an hour later, but only partially out of habit. I took another capful a few hours later once I realized that my workday was going to get hectic. It really helped me stay focused throughout the day, even while multi-tasking and with multiple distractions. It helped to curb my appetite throughout the day, which is surprising since my stomach will sometimes still act up and demand food when I’m trying to fast while stressed out. I worked out about 6-7 hours after my second capful, and noticed a slight difference in that I didn’t feel as tired after my workout. I don’t know if it’s too soon to experience enhanced endurance from the additional ketones in my body, but just something I noticed. As for the taste? Well, some have described it as “jet fuel.” Having never tasted fuel of any kind before (and never will, lol), I will say that it was like taking a shot of very strong alcohol. Something between tequila and everclear liquor. I think it’s supposed to be flavored, but it didn’t really help when taking the esters as a straight shot (with no chaser). I might try it with a chaser (fizzy water, juice, etc.) but it’s honestly not that big of a dealbreaker for me. I expect that the 3 bottles that I purchased will last at least 18 days since I don’t plan on having 10 ml every day; I should be ok with 5ml on some days. I am keen to try it with longer fasts (48+ hours) but that is for another time. I will definitely be purchasing again. While the price might seem a bit high for 3 small bottles, the price I paid for KetoneAid KE4 is still less than what I was paying for flavored ketone salts/powder which I previously purchased from another company. Also, ketone salts are not the same as ketone esters. Esters are more potent by far. If you want to add ketone esters to your daily routine, whether it’s for keto support, fasting, mental clarity or sports performance, I would recommend purchasing a bottle (or 3) of KetoneAid KE4 and experiencing its benefits for yourself. Don’t expect to drop weight just because you’re downing shots of KE4, though. You will still have to eat healthy meals, get some exercise and take care of your body. I haven’t tried any other products from this company, but I certainly will be doing so in the very near future.

## Features

## Questions & Answers

**Q: Is a ketogenic diet required? (No)**
A: No, it is not. Unlike the weaker Ketone Salts, the Ketone Ester can be used by non-Keto people.

**Q: Can anybody take it?**
A: Not for kids and pregnant women. Seek medical advice if used outside of sport.

**Q: Can it be used for weight loss?**
A: No. We strongly discourage people from buying ANY exogenous ketones for weight loss. None will burn fat for you, and it is not real "ketosis". However, it may suppress your appetite.

**Q: What is the difference between Ketone Ester and Ketone Salts?**
A: Two main differences First, most Ketone Salts are only 50% bioavailable (only half of it can be used by the body as fuel). Secondly, the Salts have a MASSIVE salt load, which may be fine for a week, but after which, good luck getting your rings off.

**Q: What's the difference between Ketone Ester and Diol?**
A: Different Ketones, Different Results. Diol has an inebriating effect, and nil to negative effect on performance. Some companies use 'science hijacking' (using Ketone Ester data) to confuse customers into thinking it is a performance drink.

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.
