The salts typically utilize sodium, potassium, calcium, or magnesium as the cation. Because these cations vary in molecular weight and valence (1+ or 2+), the amount of mineral delivered per gram of BOHB varies from 10% for the magnesium salt to 27% for potassium. Given that recommended daily intakes of these various minerals range from a few hundred milligrams up to 5 grams, whereas the daily ketone intake goal to mimic nutritional ketosis blood levels would need to be on the order of 50 grams, achieving this goal with ketone salts would severely challenge human dietary mineral tolerance.

When taken as a drink, the ester bonds are broken down to release butanediol (BDO) and D-BHB into the blood. BDO is easily metabolized by the liver to form D-BHB. Then, both molecules of D-BHB reach the blood, as the liver is unable to use ketones. Consumption of this ketone ester elevates blood ketone levels in humans safely, with few side effects.10 HVMN Ketone is WADA compliant and safe to use in all levels of sports. It is designated as a foodstuff and is FDA GRAS. Each lot is 3rd party certified and batch tested for banned substances. 


Lastly, EK products in general ​are usually in the form of salts, which is why they are referred to as BHB Salts. The BHB ketones are bound to common salts such as sodium​, calcium, magnesium and potassium​ to improve absorption rate. These salts are also the core electrolytes your body needs to help you avoid feeling mentally drained and physically lousy during the keto-flu transition period.
No this is wrong. Your body will use your own fat and any fat you eat as fuel. This counts as exogenous ketones. It won’t stop burning your fat. The same logic would say that if eating any fat your fat loss would stall and that is not true. It can help get you back into ketosis because you have certain monocarboxylic acid transporters that are upregulated when ketones are present. The evidence is physiology.

It is a good idea to weigh the pros and cons before deciding to add a calcium supplement to your diet. This includes exogenous ketone supplements. If you have any risk factors for osteoporosis, have low bone density, or have issues that prevent you from consuming a nutrient-rich diet, then the benefits of calcium supplements will likely outweigh the risks. But don’t forget that there are other avenues to improving your bone density, like strength training, and, more importantly, a well-balanced diet.
Relationship between blood ketone and glucose levels: a BMS + MCT (5 g/kg) supplemented rats demonstrated a significant inverse relationship between elevated blood ketone levels and decreased blood ketone levels (r2 = 0.4314, p = 0.0203). b At week 4, BMS + MCT (10 g/kg) and MCT (10 g/kg) showed a significant correlation between blood ketone levels and blood glucose levels (r2 = 0.8619, p < 0.0001; r2 = 0.6365, p = 0.0057). Linear regression analysis, results considered significant if p < 0.05
Participants refrained from alcohol and caffeine for 24 h prior to each visit AND were asked to consume a similar meal the night before each visit. All studies were carried out at the University of Oxford Human Physiology Laboratories and started at 0800 h following an overnight (>8 h) fast, with a minimum of 72 h between visits. Visit order was randomized prior to commencement by an administrative investigator using a pseudo-random number generator to produce a list of combinations of visit order, which were then allocated based on order of enrolment by a different investigator.
Individuals who have clinically unregulated blood sugar, such as those with diabetes, are cautioned to consult their trusted healthcare provider before choosing to use exogenous ketones. While it can be done safely, especially in the presence of a well-formulated ketogenic food plan, there may be a risk of blood sugar dropping unexpectedly low. There may be therapeutic value in this application, but close monitoring is key.
Neuroprotective benefits: A natural part of the aging process is neurodegeneration, which is largely responsible for cognitive defects like Alzheimer’s disease. Recent research suggests that exogenous ketone supplementation can drastically slow neurodegeneration and the resulting decrease in mental function.[7] However, the mechanism behind this finding remains to be elucidated; though, researchers suggest exogenous ketones act to reduce brain inflammation. Glucose, on the contrary, may actually accelerate inflammatory response in the brain.[8]
Should We Use Exogenous Ketones? Ketosis serves a purpose, and it’s probably why we’re able to survive on this planet. Being able to go without eating and use stored fats for energy is a survival tool and possibly far more as we’re now seeing with the keto diet. But it’s probably not a good idea to constantly take exogenous ketones and eat a high carb diet (high blood glucose levels). It’s not natural for the body to have high blood glucose and use ketones. This is a personal opinion, so 

I feel like I should also mention that the GI discomfort is real, people. I would recommend starting this product on a weekend or a day where you’re able to just take it easy. After my first dose, which was only 1/2 scoop, I literally just felt like lying in bed all day due to feelings of nauseousness; however, by the next day I was fine and even bumped my dose to a full scoop.

Onnit is an incredible company that’s making a massive impacts in the lives of athletes in nearly every sport. From Olympic Gold Medalists, to NFL middle linebackers, Onnit has taken athletic performance to a new level. Providing supplements, food, and training equipment, Onnit was an early adopter of the elite performance booster that is exogenous ketones!
The problem? Exogenous ketone supplements work by flooding your bloodstream with ketones. But unless you’re also eating a ketogenic diet (and producing a steady stream of ketones naturally), those supplemental ketones won’t stick around forever. “The benefit of exogenous ketones is limited due to their excretion through the urine,” explains Madge Barnes, MD, family medicine specialist with Texas Health Family Care. In other words? They’ll only work for a few hours until you pee them out. As a result, you need to keep on supplementing—which can get expensive. Twenty single-serving packets of Prüvit’s Keto//OS MAX Pure Therapeutic Ketones, for example, cost $130. (The company doesn’t specify how often you should take them.)
I have Type 2 Diabetes. I have bought a product that has Beta Hydroxybutyrate in it. Is it dangerous for me to take it whereas I am a Type 2 diabetic. Can it cause me to go into Diabetic ketoacidosis which is very dangerous for a diabetic even deadly. I have been trying to find an answer to my question and your sight seems to have the best insight on Beta Hydroxybutyrate . I bought the product without knowing it had Beta Hydroxybutyrate in it and have not tried it out of fear that it will cause me to go into Diabetic ketoacidosis. Other people I know have taken it and lost weight and I really want to take it but I am afraid. Just so you know it is on a patch with other elements in it. Please help me I look forward to your answer
Hi! My question is, how low must my current daily carb count be in order to benefit from taking your exogenous ketones? I am a 33 year old female, keeping total carbs at 100-125 grams per day. My priority is fat loss, and I do HIIT training 4-5 days a week. I’ll soon be adding in heavier strength training. I don’t function well eating less than 100 total carbs a day. Could this even benefit me? And if it will benefit me, would the befits outweigh the sodium content? I keep my sodium at 2,000 mg a day, as I’m trying to avoid water weight.
How did I do this? Simple, I went into a full fast and exercised. What prevents you from entering ketosis is all the glycogen stored in your liver and muscles. Your body can use this glycogen instead of ketones to fuel your brain, so until you deplete your stores of glycogen, you won’t be able to enter ketosis. By eating nothing, you are going to tap into the glycogen to fuel your brain because you are eating 0 grams of carbs and will also be using that glycogen to walk around all day.
However, it's important to NEVER overlook the power of exercise and of course sticking to a proper routine to get the most optimized results. The most common mistake people make is by treating any keto supplement like a "wonder drug" that will help them shred weight in their sleep. Seriously... how is that even scientifically possible. So if you are thinking about trying out a particular supplement, I would suggest two things:

I got the Peaches and Cream flavor of Perfect Keto and it's good; a nice sweet break from all the meat, cheese, and vegetables. I would recommend that you use cold water and a shaker bottle though. It takes a bit of vigorous shaking to get the lumps to melt, but it does melt seamlessly. It has a peach taste, but more like a peach with a bitter aftertaste, which I guess is expected with any ketone supplement. I read that a lot of the available supplements taste awful and this one doesn't taste awful. But don't go into it expecting it to taste like a peach pie. :-) I know some of the other supplements say to mix with a keto beverage; I've seen half and half and heavy cream as mixers because the carbs are low and fat high. I haven't tried that as I am only taking in 1,200 calories per day.
As stated above, there appears to be a difference between supplemental and dietary calcium intake, which can be important to keep in mind.  One study found aggregate calcium intakes above 1400 mg per day (from dietary and supplemental intake combined) to be associated with higher death rates, cardiovascular disease, and ischemic heart disease in women[15]. A 2014 meta-analysis found an association between dietary calcium intake and cardiovascular mortality[16]. The meta-analysis actually found a u-shaped relationship, where dietary calcium intakes that were both lower and greater than 800 mg/day were gradually associated with increased risk of cardiovascular mortality.

A recent study, Ketone Bodies Mimic the Life Span Extending Properties of Caloric Restriction, showed the effects of exogenous ketones on longevity (ketone esters, specifically) and concluded that ketones should be labeled as an “anti-aging” compound (suggesting that the real reason caloric restriction has been shown to extend life span is actually due to resulting ketosis).


For whatever reason, many patients won’t attempt a ketogenic diet—even if the evidence is clear that it could help. Doctors are often hesitant to recommend dramatic dietary shifts—even if they believe in their efficacy—to patients who are already dealing with difficult health issues. If you’ve got a picky kid with epilepsy, a pickier adult with Alzheimer’s, or a cancer patient who refuses to give up the familiar-yet-non-ketogenic foods that give him some small manner of comfort in this trying ordeal, exogenous ketones could make a big difference.
Eating around 20 grams of net carbs a day is as a foolproof way to get you into ketosis a quickly as is humanly possible. However, having 50 grams of total carbs will also get you into ketosis within three days [3]. This amount of carbs is enough to deplete glucose reserves. It's also low enough to prevent fat being used to make glucose and, instead, the body is forced to make ketones.
Her clients have had similar success. One woman, for instance, has gone from around 170 pounds to 140 pounds since April without making any initial dietary changes. She’s started to gravitate towards more keto foods over time, but still eats her favorite high-carb treats. As for exercise? Her routine consists of a couple of walks each week, Heverly says.
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.
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)!
There are things you can do to get into ketosis faster. We explain how to get into ketosis and ways to make transitioning into ketosis easier. But first, we go over some facts about ketosis you need to understand before you start your keto journey. We will also explain the science behind ketosis, including how long it realistically takes for your body to make the switch.
Ketones are an alternate energy or fuel source for brain and body that our bodies have naturally produced and used for millennia. Ketones have recently leapt to the forefront of health and wellness conversations worldwide as the scientific body of research that seeks to understand their numerous unique properties and profound systemic effects has begun to grow (see below).

Will taking exogenous slow down my fat loss? Since now before digging into my body for energy/ketones, I will first use up the exogenous ketones I ingest. Also do exogenous ketones somehow help get even more keto adapted, keeping in mind I have been on a strict keto diet without a problem and don’t mind it at all. Outside of performance improvements, do you think exogenous ketones is for someone like me who is primarily looking for fat loss.
The other potentially important distinction between nutritional ketosis and chemically-induced ketosis is the potential metabolic role played by liver AcAc production and redox status. Although the ratio of BOHB to AcAc in venous blood is typically 80% to 20%, classic studies by Cahill (1975) have observed important hepatic vein and peripheral arterio-venous gradients for this ratio in keto-adapted patients. What these observations imply is that the liver produces a higher proportion of AcAc than is found in the peripheral blood, and that this is due to uptake of AcAc in peripheral cells (principally muscle) with re-release as BOHB. In the process, the reduction of AcAc to BOHB produces NAD+, which is beneficial to mitochondrial redox state and mitochondrial function (Verdin 2015, Newman 2017).

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.


Whereas ketone esters are 100% D- form, most ketone salts are a 50/50 mix of left and right-handed beta hydroxybutyrate, which is known as a racemic mixture. These beta hydroxybutyrate molecules are linked to a mineral, such sodium (Na), calcium (Ca), potassium (K), or magnesium (Mg). This kind of ketone supplement gets broken down to left and right-handed version of beta hydroxybutyrate along with the mineral.

The ketone esters are, hands-down, the worst tasting compounds I have ever put in my body. The world’s worst scotch tastes like spring water compared to these things. The first time I tried 50 mL of BHB monoester, I failed to mix it with anything (Dom warned me, but I was too eager to try them to actually read his instructions). Strategic error. It tasted as I imagine jet fuel would taste. I thought I was going to go blind. I didn’t stop gagging for 10 minutes. (I did this before an early morning bike ride, and I was gagging so loudly in the kitchen that I woke up my wife, who was still sleeping in our bedroom.) The taste of the AcAc di-ester is at least masked by the fact that Dom was able to put it into capsules. But they are still categorically horrible. The salts are definitely better, but despite experimenting with them for months, I was unable to consistently ingest them without experiencing GI side-effects; often I was fine, but enough times I was not, which left me concluding that I still needed to work out the kinks. From my discussions with others using the BHB salts, it seems I have a particularly sensitive GI system.
