Review: Why I use KE4 BHB Ester. - #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: Amazing when used correctly. - Here is my experience with this product: Fact 1: the body's ability to process fats effeciently depends on genetic makeup. Fact 2: using this product incorrectly may render it useless or ineffecient. I took this 2 different ways & times with the same 5ml dose. There are consice instruction on the bottle. To give context, I eat ketogenically cyclically and bought this product in order to enter ketosis more quickly when I cycle back to it. In both these instances, I had been eating ketogenically with IMF 18/6 for several days and was in low ketosis. The first time I did not follow the instructions (too eager to try it to wait) and took it a half hour after eating a large meal. Nothing happened although my ketones did rise a significant amount. But as far an the feeling/energy.. nada. The second time, I took the same dose at the end of an 18 hours fast, on an empty stomach. The result was mind-blowing. Within 5-10 mins I had so much energy it was nearly overwhelming. Without eating, I immediately went to the gym (which I have not been to in several weeks), and my workout felt not only effortless but very GOOD. My state of mind was incredibly different and has remained that way throughout the day. I feel more clear-headed, like my brain has more energy than usual and given the nature of ketones, it probably does. I am an apprentice for scientific injection molding and today some math/ logistical problems I would usually have a hard time thinking through, were much easier to solve. I did eventually have a nice meal but I needed fewer calories than normal, my ketone meter was the highest I've ever seen it. I am hungry now near dinner time but have no appetite. My state of mind continues to impress me throughout the day and I am viewing this as a powerful tool for weight loss, learning, fitness and even just when you'd prefer to be in another mind-state. This is nearly a drug, having a euphoric effect along with honed senses. I am very impressed and will order more. Another thing to note is that I thought this would be very expensive as most reviewers mention having to take several doses. I think there is a high probability they are not following the directions well or taking into consideration their current metabolic state before consuming. I needed only 5ml, meaning this bottle will yield 12 doses. (I weigh 210lb). That is affordable for something that offers so much. There is hardly a supplement that could come close to this, and it is a great tool if you choose to use ketosis in a cyclical manner. Also it does indeed taste revolting. Worth it.

## Features

- Provides clean energy for athletic performance, mental clarity, metabolic health, and deep sleep
- 12 servings per bottle, 2.5 grams of Ketone Ester (d-bhb bonded to R 1,3 butanediol) per serving
- Effective and Safe: 3rd party tested for compliance with The World Anti-Doping Agency (WADA) and trusted by Tour de France cyclists, Olympians, NFL, NHL, NBA, and Professional Tennis Players.
- KE4 is not a salt, is naturally derived, 100% bioavailable, and is the only Ketone Ester that’s published FDA GRAS and Made in the USA. Contains no caffeine and no sugar. Ketogenic diet not required
- Taste Warning: Our "Very Scary Cherry" flavor improves upon the earlier "rocket fuel" taste, but it’s still rough and similar to cough syrup. If it's not to your liking, we suggest trying our Ketone Shot or our Ke4 that is sweetened with sucralose. Sucralose helps to block the bitter taste much better compared to the stevia versions.

## 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.

### ⭐⭐⭐⭐ Helpful for fasting during keto diet
*by H***I on June 24, 2025*

Though these aren't yummy, I found them effective for extending my fasting period during a ketogenic diet. They reduced my hunger, gave me sustained energy despite the fast, and did not cause an upset stomach for me. I found this product to be easy to use and reasonably effective.
