The ketogenic diet has gained significant attention recently, lauded for benefits extending beyond just weight loss. Central to this discussion is beta-hydroxybutyrate (BHB), a molecule with potentially miraculous properties. Researchers are diligently exploring whether the benefits of a ketogenic diet can be concentrated into a single supplement, and are studying the effects of this ingredient to see if it can help people live longer.
Understanding BHB: The Basics
BHB, or beta-hydroxybutyric acid, is one of the three primary ketones produced by the body during ketosis. Ketones are created when the body switches from using glucose (derived from carbohydrates) to stored fat as its primary energy source. This metabolic shift occurs during fasting, prolonged exercise, or when following a low-carbohydrate, high-fat diet like the ketogenic diet. During ketosis, fat is broken down, and BHB is synthesized, serving as an alternative fuel for the body, including the brain.
Of the three ketone bodies produced during ketosis-BHB, acetone, and acetoacetate-BHB is the most abundant in the bloodstream.
The Science Behind BHB
Traditionally, BHB was viewed as merely an alternative nutrient produced during fasting. However, research has revealed that BHB is also a signaling molecule, triggering protective mechanisms within cells.
Dr. Eric Verdin, from the Buck Institute for Research on Aging, discovered that BHB can induce a protective state in cells, making them more resistant to oxidative stress. This discovery has led to investigations into whether increasing BHB levels can extend lifespan.

Studies in mice have shown that a ketogenic diet, leading to increased BHB concentrations, can increase lifespan and improve cognitive and motor functions. This has sparked interest in exploring the ketogenic diet as a potential avenue for Alzheimer’s research and overall brain health.
Endogenous vs. Exogenous Ketosis
The body can produce ketones on its own (endogenous ketosis) or through the use of exogenous ketones, such as ketone esters or ketone salts. Endogenous ketosis is considered an evolutionary adaptation, allowing humans to survive during periods of food scarcity. When glucose is unavailable, ketones can cross the blood-brain barrier, providing energy to the brain and maintaining cognitive function.
Exogenous ketosis is achieved by ingesting ketone supplements, which raise blood ketone levels.
How BHB Works in the Body
When the body is in a fasted or glucose-depleted state, insulin levels decrease, allowing lipolysis (the breakdown of fat cells) to occur. Free fatty acids are released from fat stores, and an enzyme called BHB-dehydrogenase converts acetoacetate (AcAc) into BHB. BHB is then transported out of the liver and into circulation, where it is used as fuel. BHB molecules dissolve easily in water and blood, facilitating their efficient circulation throughout the body.
Achieving Ketosis and Increasing BHB Levels
BHB levels can be increased through:

- Fasting: After 12-16 hours of fasting, blood ketone levels begin to rise. After about two days, blood BHB levels can reach 1mM-2mM.
- Ketogenic Diet: A high-fat, low-carbohydrate diet is an effective way to maintain consistently elevated ketone levels. Studies have shown that blood BHB can be maintained around 0.27mM during a two-year ketogenic diet intervention in individuals with type 2 diabetes.
- BHB Supplements: Ketone salts, MCT oils, and ketone esters are available as supplements to raise blood BHB levels.
Types of BHB Supplements
- Ketone Salts: These are BHB molecules bound to a mineral, such as sodium, potassium, calcium, or magnesium. They are a cost-effective way to increase blood BHB levels and may provide the added benefit of minerals and electrolytes.
- MCT Oils: Medium-chain triglyceride (MCT) oils are metabolized into ketones. Brain Octane C8 MCT Oil, made of 100% caprylic acid, is known to raise ketones more efficiently than other MCT oils or coconut oil.
- Ketone Esters: These are BHB molecules bound to an alcohol molecule. They can result in rapid and sustained elevation of blood BHB.
- R-1,3-Butanediol (R-1,3-BDO): This exogenous ketone can also raise BHB levels. H.V.M.N. Ketone 2.0 contains chirally pure R-1,3-BDO and may raise blood BHB levels to the optimal range of 1.5 mM-2.5 mM for as long as 4 hours.
Potential Benefits of BHB
- Efficient Energy Source: Burning ketones for energy is highly efficient and may lead to lower production of reactive oxygen species (ROS), which are byproducts of metabolism.
- Brain Health: BHB can cross the blood-brain barrier and provide energy to the brain. It also helps increase the synthesis of GABA, an inhibitory neurotransmitter important for brain health. BHB has been shown to inhibit the NLRP inflammasome, potentially reducing inflammation in the brain.
- Cognitive Enhancement: BHB is associated with better cognitive performance and memory in Alzheimer’s disease and mild cognitive deficit. Some individuals report increased mental energy, clarity, and focus with the ketogenic diet and exogenous ketones.
- Lifespan Extension: Studies in yeast, mice, and primates have found that ketones may help extend lifespan and promote longevity.
- Appetite Control: BHB ketone levels rise, hunger runs in the background, instead of in the limelight. The appetite-controlling effect of ketones can also help with weight management.
- Metabolic Health: Keto BHB is formulated to kickstart your body's natural ketosis process. By providing a blend of Beta-Hydroxybutyrate (BHB) salts, it helps shift your metabolism from relying on carbohydrates to utilizing fat as a primary energy source.
Measuring BHB Levels
BHB levels can be measured using a blood ketone meter, similar to a blood glucose monitor. Testing for BHB is the most accurate method for assessing ketosis. Optimal BHB levels for general weight loss are above 0.6 mmol/L.
Potential Downsides and Considerations
- Supplement Quality and Effectiveness: The effectiveness of BHB supplements can vary. Some supplements may not provide sufficient ketone levels to produce a biological effect.
- Side Effects: Ketone supplements, particularly ketone salts, can cause side effects such as nausea, diarrhea, and stomach discomfort.
- Mineral Overload: Ketone salts contain minerals like sodium, magnesium, and calcium. Excessive consumption can lead to an overload of these minerals.
- Impact on Endogenous Ketone Production: Taking ketone supplements may inhibit the body's own production of ketones.
- Caloric Content: Ketones contain calories, which may hinder weight loss if consumed in excess.
- Limited Research in Humans: While studies in animals have shown promising results, more research is needed to confirm the benefits of BHB in humans.
BHB Supplements: A Word of Caution
While BHB supplements may offer some benefits, it’s important to approach them with caution. Many experts emphasize that a BHB pill should complement a healthy diet, not replace it.
Verdin cautions that the benefits of the ketogenic diet could be more complex than just increasing BHB levels. Decreased glucose levels, or a critical ratio between BHB and glucose, may also play a role.
It’s also important to note that the claimed benefits of the ketogenic diet in humans are still under investigation. While anecdotal evidence supports many claims, more research is needed.
Potential Applications of BHB
Research suggests that BHB may have therapeutic potential for a variety of conditions, including:

- Epilepsy
- Cognitive impairment
- Cancer
However, further studies are needed to confirm these benefits in humans and to determine the optimal dosage and form of BHB for each condition.
The Future of BHB Research
Researchers are actively exploring the potential of BHB to improve health and extend lifespan. Future studies will focus on:
- Duplicating the beneficial effects observed in mice using BHB supplements.
- Determining the threshold of BHB in the bloodstream needed to achieve desired effects.
- Investigating the long-term effects of BHB supplementation.
- Exploring the potential of BHB for treating various diseases.
