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 love it more than I thought I would - 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. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07S7F9X9Z | | Age Range Description | Adult | | Best Sellers Rank | #22,436 in Health & Household ( See Top 100 in Health & Household ) #625 in Blended Vitamin & Mineral Supplements | | Brand | KetoneAid | | Brand Name | KetoneAid | | Container Type | Bottle | | Customer Reviews | 4.0 out of 5 stars 1,314 Reviews | | Diet Type | Keto | | Dosage Form | Liquid | | Flavor | Original | | Item Form | Liquid | | Manufacturer | KetoneAid | | Material Features | Caffeine Free, Sugar Free | | Material Type Free | Caffeine Free | | Number of Items | 1 | | Primary Supplement Type | Ketone ester | | Product Benefits | Mental Clarity | | Special Ingredients | No sugar, no caffeine, not a ketone salt, Stevia and natural cherry flavor | | Total Servings Per Container | 12 | | UPC | 860001899207 | | Unit Count | 2 Fluid Ounces | ## Product Details - **Age Range (Description):** Adult - **Brand:** KetoneAid - **Diet Type:** Keto - **Flavor:** Original - **Item Form:** Liquid - **Package Information:** Bottle - **Primary Supplement Type:** Ketone ester - **Product Benefits:** Mental Clarity - **Special Ingredients:** No sugar, no caffeine, not a ketone salt, Stevia and natural cherry flavor - **Unit Count:** 2 Fluid Ounces ## Images ![KetoneAid Ke4 Ketone Ester Concentrate | 1 Count | Exogenous D-BHB Ester, Not a Ketone Salt, No Sugar, No Caffeine, 12 Servings per Bottle - Image 1](https://m.media-amazon.com/images/I/61MLHo1GSTL.jpg) ## Available Options This product comes in different **Size, Flavor** options. ## Questions & Answers **Q: Is a ketogenic diet required? (No)** A: No, it is not. Unlike the weaker Ketone Salts, Veech 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 Veech 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 Veech Ketone Ester and Diol?** A: Different Ketones, Different Results. Diol has a sedative-like inebriating effect, & 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Why I use KE4 BHB Ester. *by C***E on October 28, 2019* #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.

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. ## Frequently Bought Together - KetoneAid Ke4 Ketone Ester Concentrate | Not a Ketone Salt, No Sugar, No Caffeine | Exogenous D-BHB Ester | 12 Serving Per Bottle (1 Count) - Hard Ketones Dr. Up Unsweetened (aka NASTY) | 0.0% Alcohol Alternative with 17g Ketohol | 12 Pack, 8.4 Oz Cans - KetoneAid Ketone Shot | Ketone Ester Energy | No Sugar, No Caffeine (6 Count) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/145128631-ketoneaid-ke4-ketone-ester-concentrate-1-count-exogenous-d-bhb](https://www.desertcart.co.za/products/145128631-ketoneaid-ke4-ketone-ester-concentrate-1-count-exogenous-d-bhb) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-11*
