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.
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.
Since beta hydroxybutyrate is transported throughout the body via the blood, the best way to check your true BHB levels is through a blood test. The good news is that you can just use a simple finger prick and an at home method that is very similar to how diabetics check their glucose. The bad news is that it can be pretty expensive. Each strip and time you test can be around $4-6.
Ketones naturally exist in the body, being created during the process of fat metabolism and are therefore safe to consume even during pregnancy or breastfeeding. Supplements such as Ketologie’s PROBHB are simply providing ketones from an external (exogenous means literally ‘outside of the body’) source. However, if you suffer from any medical conditions and/or are on medications, it is always advisable to consult your health care provider prior to starting any new nutritional or dietary supplement.
When your body is done using up a certain substrate to create energy (acetyl-CoA) after eating carbohydrates, it will start to find creative ways to get the job done. This is something that you want to happen. This is the switch to ketosis. If you didn’t do this, you’d be dead after fasting for a very short period of time. Under normal circumstances, the liver will start making beta-hydroxybutyrate from long chain and medium chain fatty acids that are liberated from your fat tissue. You are turning fat into fuel. Good work. This is why people can fast for months at a time and still function like normal humans.
Personally, I think it is wise to include a regular carb meal in your diet if you are going to follow a ketogenic diet. Long term ketogenic diets do seem to downregulate your thyroid and metabolism, and a weekly carb meal (or carb day) can help avoid this. The Carb Nite diet by J. Kiefer is a good example of this. And BJJCaveman posted his labs showing how a weekly carb meal helped his thyroid HERE.
Consuming exogenous ketones isn't the same as following a ketogenic diet–the ketones in the blood haven't been naturally produced by the breakdown of fat stores. However, scientists believe many of the health benefits of the keto diet and fasting (aside from weight loss) are triggered by ketones. Therefore, raising ketone levels through either endogenous or exogenous ketosis could help to improve health and performance by:
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).
Improved cognition: Elevated plasma ketone concentrations divert the brain to utilize ketone bodies for synthesis of phospholipids, which drives growth and myelination. Normally, glucose would be the preferred substrate, which is much less efficient.14 BHB seems to act as a signal for neuronal pathways. These enhance synaptic plasticity, cognition and neuronal stress resistance. 15 In rat studies, ingestion of a ketone ester for 5 days improved their spatial learning and memory. 16.
Recently, a friend of mine’s dad had high blood pressure. His doctor told him to stop consuming eggs and to avoid adding extra salt to his foods. That’s it. His recommendation was to rid a good, high-quality protein source, yet French fries, chicken nuggets, and even chicken noodle soup were all presumably okay. I’ll never understand some of these recommendations; nonetheless, they happen day in and day out, all over the world.
Been using yur stuff for the last week and tyere is absolutely no change in the amount of ketones based on the ketone strips i use to monitor ketone levels. I use another product as well and switched back and have sustained higher levels of ketones most of the day. Is there a reason that your product doesnot produce the results based on the strip test? I am a larger guy, 260 possibly need more? I have 2 tubs to go through and am not overly optimistic about whats going on.
Hi.. I’ve recently started drinking Keto OS Max and have lost about 20 pounds in the past 4 weeks without strictly sticking to the keto diet and have not exercised once. The only issue I have with Keto OS is the price really. I am wondering how the other BHB/MCT products like Ketond and PerfectKeto compare to Keto OS and what product on the market comes closest to the Keto OS recipes beneficial ingredients. TIA
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.
The two compounds commonly referred to as ‘ketone bodies’ (BOHB and AcAc) are produced and used for multiple purposes across nature from algae to mammals, but seldom in concentrations useful for extraction as human food. For this reason, the source of most exogenous ketones is chemical synthesis. Furthermore, most current research and use of ketone supplements focuses on BOHB. That is because AcAc is chemically unstable – it slowly breaks down to form acetone by releasing of one molecule of CO2.
The classical KD consists of a 4:1 ratio of fat to protein and carbohydrate, with 80–90 % of total calories derived from fat . The macronutrient ratio of the KD induces a metabolic shift towards fatty acid oxidation and hepatic ketogenesis, elevating the ketone bodies acetoacetate (AcAc) and β-hydroxybutyrate (βHB) in the blood. Acetone, generated by decarboxylation of AcAc, has been shown to have anticonvulsant properties [28–32]. Ketone bodies are naturally elevated to serve as alternative metabolic substrates for extra-hepatic tissues during the prolonged reduction of glucose availability, suppression of insulin, and depletion of liver glycogen, such as occurs during starvation, fasting, vigorous exercise, calorie restriction, or the KD. Although the KD has clear therapeutic potential, several factors limit the efficacy and utility of this metabolic therapy for widespread clinical use. Patient compliance to the KD can be low due to the severe dietary restriction - the diet being generally perceived as unpalatable - and intolerance to high-fat ingestion. Maintaining ketosis can be difficult as consumption of even a small quantity of carbohydrates or excess protein can rapidly inhibit ketogenesis [33, 34]. Furthermore, enhanced ketone body production and tissue utilization by the tissues can take several weeks (keto-adaptation), and patients may experience mild hypoglycemic symptoms during this transitional period .
Price: The supplements are expensive – very expensive. At the top end, if you follow Prüvit’s guidelines on “getting in the n8tive zone” (which is such a gimmicky marketing slogan it almost makes me cringe), you will require 2 servings of their Keto-OS product per day. This means around 60 servings per month, which will set you back a whopping $390 per month if you buy direct from their website! In the case of Prüvit, this is in part due to the multi-level marketing structure they operate under.
Hello, I’ve tried several different Exogenous Ketone supplements and I believe Perfect Keto may be the best I’ve tried. Thus far I’ve had Keto//OS from Pruvitt, Kegenix, KetoForce, KetoCaNa and Ketond. Out of all these brands both Perfect Keto and Ketond have been the products that hack me into Ketosis quick and for longer periods of time. Perfect Keto is less expensive that Ketones from Pruvitt mainly because Pruvitt and their Network Marketing is all about making money. The flavors of Perfect Keto are much better than Pruvitt.
I don’t think we even need a drumroll here… Based on my background research into ketone-supplement companies, the survey of Diet Doctor users and the experiment itself, we cannot recommend taking these supplements. I can personally think of many more beneficial ways to invest money in my health, such as buying grass-fed meat and organic vegetables, or even buying a bicycle and riding it outside in the sunshine.
Effects of ketone supplementation on triglycerides and lipoproteins: Ketone supplementation causes little change in triglycerides and lipoproteins over a 4-week study. Graphs show concentrations at 4-weeks of total cholesterol (a), Triglycerides (b), LDL (c), and HDL (d). MCT supplemented rats had signfiicantly reduced concentration of HDL blood levels compared to control (p < 0.001) (b). One-Way ANOVA with Tukey’s post hoc test, results considered significant if p < 0.05. Error bars represent mean (SD)
Exercise or performing an extensive workout during the day is a perfect way to burn all those glycogen reserves in your body. Performing a HIIT or High Intensity Interval Training is a perfect type of exercise to do this. So, the next morning when you are awake, get set on an intense exercise session (remember, in the morning, not the afternoon). This will keep the cortisol level lowered during the evening when you wish to have some rest.
As ketone drinks can deliver nutritional ketosis without fasting, we investigated the effect of food on KE uptake and metabolism. It is well documented that food in the gut can slow, or prevent, the uptake of small hydrophilic hydrocarbons, such as βHB (Melander, 1978; Toothaker and Welling, 1980; Horowitz et al., 1989; Fraser et al., 1995), so decreased gut βHB uptake is probably the cause of lower blood βHB following the meal. Despite higher blood βHB concentrations in the fasted state, the meal did not alter plasma AcAc. This suggests that the rate of conversion of βHB to AcAc may not match the rate of appearance of βHB following KE consumption. Alternatively, meal-induced changes in the hepatic ratio of NAD+:NADH may have altered the conversion of βHB to AcAc (Himwich et al., 1937; Desrochers et al., 1992).
Is keto safe? Putting yourself through this type of therapy isn't always easy and the process can take some getting used to, in particular during the initial stages when people must go through a period of fasting in order to raise ketone bodies faster. Of course, by doing this, it can put your body through a bit of shock and may cause a person to experience some short-term side effects until their bodies begin to adapt to the lifestyle and any BHB supplement they may be taking.
The keto-esters are more appropriate for delivering higher doses of BOHB, but with repeated dosing can push the limits of taste and GI tolerance. There has been fairly extensive research on a compound 3-hydroxybutyl 3-hydroxybutyrate that is converted via hydrolysis and liver metabolism to yield 2 molecules of ketones, presumably mostly D-BOHB (Clarke 2012 and 2014). In a study involving lean athletes, an approximate 50 gram dose raised blood BOHB levels to 3 mM after 10 min and reached 6 mM by 20 min. Submaximal exercise resulted in increased ketone disposal from 2 to 3 hours and contributed significantly to whole body energy use during exercise (Cox 2016). This product has been shown to significantly reduce appetite after a single dose (Stubbs 2018) but its effect on body weight in humans over a longer period of time has not been studied, nor has its effect on blood glucose control been reported in humans with type 2 diabetes. However a single dose prior to a glucose tolerance test in healthy humans reduced blood glucose area-under-curve by 11% and non-esterified fatty acid area-under-curve by 44% (Myette-Cote 2018).
Why is this desirable? Think about energy production in your body much like macro energy consumption on a planetary level. Coal is gross and dirty and messes tons of different things up. You need to continue to burn it to get energy. Solar power is free, clean and pretty much limitless. This is pretty much the same story when you are burning carbs (coal) versus fats (solar) for energy.
As Dr. Ryan Lowery pointed out to me, ketone supplements could play an important role in the future for elite sports performance, for example, or for people with brain injuries who cannot metabolize glucose properly. I am encouraged that scientists are working to develop these possibilities and, as long as plenty of peer-reviewed scientific research is done into the products being developed, I could feel more positive about the ketone salts in the future. For now, that scientific support is lacking.
A sound sleep is highly associated with the dark. Also, studies have proven that our body’s natural defense mechanisms against cancer cells get activated in the absence of light (that’s why sleeping is the best way to natural healing). So turn off all the lights, TV screen, lamps, and all other light emitting devices at least 30 minutes before going to sleep. With this trick, you are actually preparing yourself to fall asleep.
Plenty of supplements make you a fractionally better sportsman and these are no different. The synthetic exogenous ketones helped Olympic-caliber cyclists cover an average of 411 additional meters during a 30-minute time-trial, which resulted in a two percent increase in overall speed, found a paper in Cell Metabolism. That can be the difference between feeling the glorious tug of the winner’s ribbon across your chest or rolling in with the stragglers.
Exogenous Ketones have been shown in performance studies of both humans and animals to improve metabolic efficiency, which in essence means that your body is using better fuel that burns more efficiently over longer periods of time, and decreases the amount of fuel you need while performing. Where glucose fails (glycogen depletion), ketones pick up the slack!
It’s not clear that the Weir coefficients used to estimate EE are relevant for someone in ketosis, let alone someone ingesting exogenous BHB. (The Weir formula states that EE is approximated by 3.94 * VO2 + 1.11 * VCO2, where VO2 and VCO2 are measured in L/min; 3.94 and 1.11 are the Weir coefficients, and they are derived by tabulating the stoichiometry of lipid synthesis and oxidation of fat and glucose and calculating the amount of oxygen consumed and carbon dioxide generated.) While this doesn’t impact the main observation—less oxygen was consumed with higher ketones—it does impact the estimation of EE and substrate use.
