Emerging evidence supports the therapeutic potential of the ketogenic diet (KD) for a variety of disease states, leading investigators to research methods of harnessing the benefits of nutritional ketosis without the dietary restrictions. The KD has been used as an effective non-pharmacological therapy for pediatric intractable seizures since the 1920s [1–3]. In addition to epilepsy, the ketogenic diet has elicited significant therapeutic effects for weight loss and type-2 diabetes (T2D) [4]. Several studies have shown significant weight loss on a high fat, low carbohydrate diet without significant elevations of serum cholesterol [5–12]. Another study demonstrated the safety and benefits of long-term application of the KD in T2D patients. Patients exhibited significant weight loss, reduction of blood glucose, and improvement of lipid markers after eating a well-formulated KD for 56 weeks [13]. Recently, researchers have begun to investigate the use of the KD as a treatment for acne, polycystic ovary syndrome (PCOS), cancer, amyotrophic lateral sclerosis (ALS), traumatic brain injury (TBI) and Alzheimer’s disease (AD) with promising preliminary results [14–26].


KE was synthesized as previously described [29]. BMS is a novel agent (sodium/potassium- βHB mineral salt) supplied as a 50 % solution containing approximately 375 mg/g of pure βHB and 125 mg/g of sodium/potassium. Both KE and BMS were developed and synthesized in collaboration with Savind Inc. Pharmaceutical grade MCT oil (~65 % caprylic triglyceride; 45 % capric triglyceride) was purchased from Now Foods (Bloomingdale, IL). BMS was formulated in a 1:1 ratio with MCT at the University of South Florida (USF), yielding a final mixture of 25 % water, 25 % pure βHB mineral salt and 50 % MCT. BD was purchased from Sigma-Aldrich (Prod # B84785, Milwaukee, WI).
Hi. Thanks for the informative article! I have fallen down the exogenous ketone rabbit hole for the last 2 days trying to figure everything out. I am currently on a nutritional ketonic diet but after 8 months, I am finding it difficult to stay on it 100%. I would like to remain on a low-carb diet, but also have a little more flexibility in my food choices. If you take the expense out of the equation, which product would you recommend for someone who wants to use ketosis as a method of weight loss? Thank you so much.

The “BHB salt” is simply a compound that consists of sodium (Na+), potassium (K+), and the ketone body β-hydroxybutyrate.  In supplements like Pruvit’s Keto OS  these individual components are being held together by ionic bonds; however, when you consume the product, it is absorbed into the blood where it dissociates into free Na+, K+, and BHB since it is a water-based solution.  Thus, consuming the product directly and immediately puts more ketones into your blood.
Not everything is perfect with Ketōnd, so there are a few things you should know. One is that it is extremely powerful. The company is pretty adamant about taking the correct dosage - and they are right. This isn't your typical ketone supplement. I'd recommend starting off at half a scoop, even if you are used to taking a different ketone supplement. Odds are if you have your product was underdosed. So, it’s kind of a pain to remember all the time, but once you feel good with the half serving then you can work your way up to a full scoop. If you think it is too strong for you – just take one serving a day, not two, and you will be okay.

I had heard horror stories about how bad ketone esters tasted (like “rocket fuel”!) so was prepared for the worst. I followed their instructions and drank the contents of the bottle in one gulp, then chased it with a sip of sparkling mineral water. While not the most pleasant aftertaste, the flavor wasn’t any worse than after a shot of well tequila. Within 15 minutes I was already well into therapeutic ketosis, and after 30 minutes my ketone meter displayed a “HI” error message (meaning my level was greater than 8.0 mmol/L)!
Lots of good info but some things are just plain wrong. It takes 2 days max to get into ketosis if you stop eating carbs. Your body can only store roughly 2 days worth of glycogen. When those stores are exhausted your body will immediately turn to fat. It may take a week or several weeks to get “keto adapted” but it simply won’t ever take you more than 2 days to get into a state of ketosis.
Ketone supplementation did not affect the size of the brain, lungs, kidneys or heart of rats. As previously mentioned, the rats were still growing during the experimental time frame; therefore, organ weights were normalized to body weight to determine if organ weight changed independently to growth. There could be several reasons why ketones influenced liver and spleen weight. The ratio of liver to body weight was significantly higher in the MCT supplemented animals (Fig. 5). MCTs are readily absorbed in the intestinal lumen and transported directly to the liver via hepatic portal circulation. When given a large bolus, such as in this study, the amount of MCTs in the liver will likely exceed the β-oxidation rate, causing the MCTs to be deposited in the liver as fat droplets [94]. The accumulated MCT droplets in the liver could explain the higher liver weight to body weight percentage observed with MCT supplemented rats. Future toxicology and histological studies will be needed to determine the cause of the observed hepatomegaly. It should be emphasized that the dose in this study is not optimized in humans. We speculate that an optimized human dose would be lower and may not cause hepatomegaly or potential fat accumulation. Nutritional ketosis achieved with the KD has been shown to decrease inflammatory markers such as TNF-α, IL-6, IL-8, MCP-1, E-selectin, I-CAM, and PAI-1 [8, 46], which may account for the observed decrease in spleen weight. As previously mentioned, Veech and colleagues demonstrated that exogenous supplementation of 5 mM βHB resulted in a 28 % increase in hydraulic work in the working perfused rat heart and a significant decrease in oxygen consumption [28, 41, 42]. Ketone bodies have been shown to increase cerebral blood flow and perfusion [95]. Also, ketone bodies have been shown to increase ATP synthesis and enhance the efficiency of ATP production [14, 28, 40]. It is possible that sustained ketosis results in enhanced cardiac efficiency and O2 consumption. Even though the size of the heart did not change for any of the ketone supplements, further analysis of tissues harvested from the ketone-supplemented rats will be needed to determine any morphological changes and to understand changes in organ size. It should be noted that the Harlan standard rodent chow 2018 is nutritionally complete and formulated with high-quality ingredients to optimize gestation, lactation, growth, and overall health of the animals. The same cannot be said for the standard American diet (SAD). Therefore, we plan to investigate the effects of ketone supplements administered with the SAD to determine if similar effects will be seen when the micronutrient deficiencies and macronutrient profile mimics what most Americans consume.
How to get into ketosis in 24 hours you ask? Can it be done? Yes, it can happen. But only for people who have already been keto-adapted and may have dropped out of ketosis for a short period of time, like after a cheat day. Those people can follow these steps to get back into ketosis quickly. However, if you are just starting keto you have a lot of work to do before your body will let you get into ketosis.

The year before last I somehow full on Rocked at the keto diet lost 100lb, and was taking adderall. I am transitioning back into it again also back on the adderall, but i seem to have no energy and last time my doc did my blood work i was only 16% hydrated. Obviously it’s a huge problem for me, staying hydrated and trying to lift the fogginess. I am type 2 diabetic and my doctor is on board with me trying all to keep my sugars down YEAH!!! I have never tried any exogenous product. My body seems to not absorb much vitamins. Can anyone make a or any suggestion to me as to how to get this under control?
To answer that question, we're going to break down the methods that can get you the results you want in the least possible time. We're going to let you in on a couple of tips and tricks that you will need to know before trying out the diet yourself. We guarantee you that these tips will help you achieve success in your chosen diet quickly and easily.

International Patent # PCT/US2014/031237, University of South Florida, D.P. D’Agostino, S. Kesl, P. Arnold, “Compositions and Methods for Producing Elevated and Sustained Ketosis”. P. Arnold (Savind) has received financial support (ONR N000140610105 and N000140910244) from D.P. D’Agostino (USF) to synthesize ketone esters. The remaining authors have no conflicts of interest.
Over the past couple years, I’ve tried a number of ketone supplements, generally to enhance a longer fast or to offer an edge before one of my Ultimate Frisbee evenings. This Kegenix variety is one I’d recommend. I’ve also used Quest Nutrition MCT oil powder with good results as well, but there are plenty of other solid formulations to choose from.
When you restrict carbs, the kidneys excrete a lot of sodium. Not replacing this sodium can leave you feeling light headed. I recommend having a big glass of spring water with ½ teaspoon of Celtic sea salt twice a day (first thing in the morning and midafternoon are two times that work well). A long with this, make sure you use a lot of salt on your meals.
In a keto-adapted individual where ketone metabolism is brisk with up to 100 grams or more being oxidized (i.e., ‘burned for energy’) daily, the small amount lost in breath and urine as acetone is minor. But because this breakdown occurs spontaneously without needing the help of enzymes, it also happens to AcAc in a stored beverage or food (even in an air-tight container), making the shelf-life of AcAc-containing products problematic. Thus all current ketone supplements consist of BOHB in some form rather than the naturally occurring mix of BOHB and AcAc produced by the liver.
The effects of ketone drinks on endogenous insulin secretion are unclear. Whilst the small increase in plasma insulin after KE and KS drinks may have been due to the small quantity of dextrose in the diluent, it has been proposed that ketones could potentiate or even stimulate insulin secretion. Isolated pancreatic islets secreted insulin when stimulated by ketones at glucose concentrations of >5 mM (Biden and Taylor, 1983), and small amounts of insulin are secreted in vivo following exposure to exogenous ketones in animals (Madison et al., 1964; Miles et al., 1981). In response to an intra-venous 10 mM glucose clamp, ketone ester drinks increased glucose uptake and plasma insulin (Holdsworth et al., 2017). The increases in insulin with ketone drinks taken whilst fasted were small compared to the increases seen when the ketone ester drink was consumed with a meal and with consumption of a dextrose drink. Furthermore, the lack of difference in peak plasma insulin between the two latter conditions indicates that nutritional ketosis did not inhibit or increase normal carbohydrate induced insulin production.
Our mission at Ketologie is to help educate and assist people in transitioning to a ketogenic way of eating for life. Primarily, we support people achieving this via adopting a VLCHF or ketogenic way of eating. Exogenous ketones can however play a useful role in transitioning to and maintaining a ketogenic lifestyle, and so we have exhaustively researched and developed a unique, “next level” ketone supplement that focuses specifically on optimizing health via the gut-brain axis.
Core BHB™ provides pure goBHB™ in an all-natural formula with no artificial sweeteners, making ideal for those on the keto diet, athletes, and people who are health-conscious. Even if you’re on a high-carb diet, Core BHB™ will rapidly elevate blood ketone levels and help your body enter a state of ketosis (often with 30 minutes of consumption). In turn, you will experience increases in energy, fat loss, endurance, and mental acuity. With regular use of Core BHB™, you can also speed up the transition from a higher-carb diet to the ketogenic diet and reduce symptoms of the “keto flu”.

Many of us have heard the saying, “Don’t blame the butter for what the bread did.”  Similarly, don’t blame the sodium for what the fries did.  Sodium has been shown to help maintain fluid balance, normal muscle and nerve function, and blood pressure and volume[1]. The movement of sodium ions and other electrolytes across cell membranes helps to facilitate muscle contraction and nerve impulses. Electrolytes also help to maintain fluid balance across intracellular and extracellular spaces and blood volume.

While ketone salts are widely available, unfortunately in the near-term ketone esters are in short supply and the only people who will be able to afford taking them several times per day will be elite athletes, the military, corporate CEO-types, and professional poker players. Even with economies of scale and ramping up production, the cost of raw materials to produce pure ketone esters will keep their price tag prohibitively high for most people, but could realistically get down to a few dollars per gram.
 “Though the small amount of carbohydrates in the diets may be more than balanced by the potential sugar production from the large amount of protein to keep the ratio of fatty acid to glucose below the generally accepted level of ketogenesis, the respiratory quotient data suggest another mechanism also” ß (most likely the CPT-1A mutation, which had not been discovered at that time)
Think about it like building muscle, good supplements can enhance your results, but if you don't eat right and exercise, supplements are just useless. You can't just sit on the couch to watch TV, eat potato chips all day and drink some supplements and expect to gain muscle. A supplement is not a miracle. It's just an addition and before you add it to your diet, you need to get the basics right first, which is dieting and exercise in the case of building muscles. The supplements are not going to lift the heavy weights for you. You do!
Hi! I have what might be a silly question about using these supplements. What happens if you are taking them and your diet goes off the rails, like you take the Keto//OS and then eat a bunch of pizza or chocolate. Does your body just immediately revert back to using the carbs for energy instead of the ketones? Or, if it doesn’t, would that mean your body would just store those carbs as fat? I realize that ideally you wouldn’t eat the pizza, but sometimes I do and I worry about what exactly I’m doing to my body if I’ve also taken ketones.
Working memory involves temporarily storing and manipulating information. The game involves seeing three cards – a top card with a symbol that then moves along a track and is flipped over, exposing a new card above. The goal is to remember the symbol of the cards two cards back and indicate whether it matches the visible card or not. If you have ever played dual n-back games, this is very similar.
So by taking in the perfect keto base, which are the exogenous ketones (BHB). This will easily put my body into ketosis rather than having to do the ketosis diet? I cant make up my mind on whether to buy the ketone powder and/or the MCT oil powder. What is the benefit of the MCT oil powder? When i read about it on the perfectketo website, it sounds like it does the same job as the perfect keto base. I’m also curious about the bone broths others sell for ketose related stuff. Is it very benedficial even when it has about 600mg of sodium in it?
Nutritional ketosis induced with the KD has proven effective for the metabolic management of seizures and potentially other disorders [1–26]. Here we present evidence that chronic administration of ketone supplements can induce a state of nutritional ketosis without the need for dietary carbohydrate restriction and with little or no effect on lipid biomarkers. The notion that we can produce the therapeutic effects of the KD with exogenous ketone supplementation is supported by our previous study which demonstrated that acutely administered KE supplementation delays central nervous system (CNS) oxygen toxicity seizures without the need for dietary restriction [29]. We propose that exogenous ketone supplementation could provide an alternative method of attaining the therapeutic benefits of nutritional ketosis, and as a means to further augment the therapeutic potential of the KD.
However, we will not be commenting on ketone esters since there are big differences between them and ketone salts, and the ketone salts are the ones that have been heavily commercialized and marketed to the public over recent years. Ketone esters may be more difficult to market due to their having an unpleasant taste. We may look more deeply into the esters in the future.
Administration of ketone supplementation significantly reduced blood glucose over the course of the study (Fig. 3a, b). MCT (5 g/kg) decreased blood glucose compared to control within 30 min which was sustained for 8 h at baseline and at week 1. MCT (10 g/kg) likewise decreased blood glucose within 30 min and lasted through the 12 h time point during weeks 2, 3, and 4. BMS + MCT (5 g/kg) lowered blood glucose compared to control from hours 1–8 only at week 1. BMS + MCT (10 g/kg) lowered blood glucose compared to control within 30 min and remained low through the 12 h time point at weeks 2, 3, and 4. Rats supplemented with BMS had lower blood glucose compared to control at 12 h in week 4 (10) (Fig. 3a). Administration of BD did not significantly change blood glucose levels at any time point during the 4-week study. KE (5 g/kg) significantly lowered blood glucose levels at 30 min for week 1, 2, 3, and 4 and was sustained through 1 h at weeks 2–4 and sustained to 4 h at week 3. (Fig. 3b).
Exogenous ketones drinks are growing in popularity as a method to elevate blood ketone concentrations and mimic a ketogenic diet without the need for dietary changes (Ari et al., 2016; Cox et al., 2016; Kesl et al., 2016; Caminhotto et al., 2017; Evans et al., 2017). The present study describes the pharmacokinetic and pharmacodynamics properties of ketone ester and salt drinks in humans at rest, and characterizes the effects of a prior meal, which is pertinent to use as a dietary supplement. The main findings were that KE drinks elevated blood d-βHB > 50% higher than KS drinks, the latter significantly increasing blood l-βHB, which was metabolized more slowly by the body. Both drinks had similar effects on FFA, TG, glucose and electrolyte concentrations, although with disparate effects on pH. A prior meal decreased total blood d-βHB appearance after a KE drink. Finally, either three KE drinks or nasogastric feeding effectively maintained nutritional ketosis over 1 mM for 9 h.

It comes in a small bottle that usually contains 50-100 strips depending on the type you choose. It’s very thin, and on one end there’s a small square of paper (this is the end you dip in the urine). If there are ketones in your urine, the little paper will change color. The darker it is (light pink up to a purple color) the more it is in your urine. On the bottle, there’s a picture you compare the color of the paper with that can be a very good indication of your current ketone state. 
Would this be helpful for someone with Hypothyroidism and HPA Axis dysfunction? I started a Keto/IF lifestyle after watching your videos early July and though I feel so much better inflammation wise, I am not seeming to be super fat adaptive as of yet. Would KetoEdge stress out my body with these things going on? I’d love to try it but want to make sure first.
Those of you who have tried this form of weight loss before are probably more than aware of how hard it can be to first get your body to adapt to such a dramatic change in your daily intake of food, let alone without the help of a single exogenous ketone supplement. And the situation isn’t made any easier if you use a poor quality ketosis supplement because the wrong ketone product may actually do you more harm than good.
