Fuel for brains
KetoSwiss is bringing ketones back into the modern world, especially into the lives of neurological patients, with a novel approach: We produce them in the lab and give them on top of a (hopefully healthy) diet.
We have just finished the development of our first flagship product for the dietary management of migraine: MigraKet™. Migraine affects around 1B people worldwide and while it is the most common neurological disorder, solutions targeting the root cause are lacking.
Our research suggests that migraine is associated with metabolic impairment of the brain (see Scientific Background for more information), and MigraKet™ is a response to the special energy needs of a migraineur's brain has. Because the key ingredient of MigraKet™ is a human identical metabolite, it is safe in the doses we recommend. The concept behind the product is patented by us, has been awarded several prizes and was recently published in Nature Neurology.
While we prepare for the launch of MigraKet™, we continue working on further product development for both migraine and other neurological and psychiatric disorders with known metabolic components.
MigraKet™: First Go-to-Market Medical Food under Brain Ritual Brand
Our mission is to provide an effective solution to migraines (and other neurological diseases) without the side effects of classical pharma products, based on solid scientific research and inspired by evolution.
MigraKet is a one-stop shop & a nutritional powerhouse:
MigraKet contains most micronutrients necessary for energy production in addition to macronutrients (such as human identical ketone bodies -the brain’s preferred fuel source).
Key ingredients have demonstrated efficacy and safety in migraine.
High quality, human-identical ingredients.
Transparent, natural, lab-tested.
Daily dose: 2x 9g powder dissolved in water
Ketone bodies: The forgotten alternative brain fuel
Today, due to our carbohydrate-rich diets, our brains are fuelled almost exclusively by glucose. However, 10,000 years ago, during times of fasting when carbohydrates were not available, the body produced an efficient long-lasting alternative energy substrate when glucose was not available: ketone bodies (Fig 1). In practice, the human brain has been engineered to burn ketone bodies whenever available. The brain prefers ketone bodies over glucose when given the choice and babies are born producing ketone bodies.

Potential causes of migraine
Recent research suggest that migraine is is associated with energy metabolic impairment of the brain., Our recent Nature Neurology Review on the Metabolic Face of Migraine shows cerebral metabolomics that might be involved in migraine pathogenesis and therapeutic targets. In Fig. 2 glucose crosses the blood–brain barrier via insulin- independent glucose transporter 1 (GLUT1) (step 1), deficiency of which can contribute to migraine, as can insufficient glucose, oxygen, water or minerals. GLUT1 is expressed by capillary endothelial cells and astrocytes. Non- oxidative glucose metabolism produces pyruvate (step 2), which is converted to lactate and shuttled to neurons through monocarboxylate transporters (MCTs; mainly MCT1 and MCT4 in astrocytes and MCT2 in neurons). In neurons, this lactate can be used as an energy substrate following its conversion to pyruvate, which can be converted into acetyl- coenzyme A (Acetyl- CoA) and fed in turn into the tricarboxylic acid cycle (TCA) (step 3). Neurons can also take up glucose via neuronal GLUT3 (step 4), which is insulin- dependent and can be influenced by insulin resistance.

Ketone bodies (β- hydroxybutyrate (BHB) and acetoacetate (AcAc)) cross the blood–brain barrier via MCT1 transporters (step 5) and penetrate astrocytes via MCT1 or MCT4 (step 6) and neurons via MCT2 (step 7). BHB provides an alternative to glucose as a substrate for oxidative phosphorylation; it is converted to AcAc and, subsequently, acetyl- CoA, which enters the TCA to produce ATP (step 8). BHB also has antioxidant properties and, compared with glucose, its conversion to ATP produces fewer reactive oxygen species (ROS) per oxygen molecule consumed. Increased ROS, nitric oxide, lack of energy substrates or lack of necessary co- enzymes inhibit mitochondrial function and reduce ATP levels (step 9). Antioxidants and co- enzymes, such as riboflavin, other B vitamins, coenzyme Q10 (CoQ10), magnesium, α- lipoic acid (AL A), l- carnitine and the anticonvulsant topiramate, support mitochondrial function and protect against migraine.

The potential migraine protective mechanisms of ketone bodies
Research suggest that amongst key migraine pathophysiological mechanisms are hypometabolism, decreased glucose transport (including glucose transporter 1 (GLUT1) deficiency), reduced mitochondrial functioning, increased cerebral excitability, increased cortical spreading depressions (CSD) incidence, increased oxidative stress (reactive oxygen species (ROS)), increased inflammation, microbiome abnormalities and reduced digestive health.
D-β-hydroxybutyrate (D-BHB; with or without the context of a ketogenic diet) has been shown to positively influence each of these mechanisms (Fig. 3): increasing cerebral metabolism, increasing glucose transport (including glucose transporter 1 (GLUT1) deficiency), increasing mitochondrial functioning, reducing cerebral excitability, decreasing cortical spreading depressions (CSD) incidence, reducing oxidative stress (reactive oxygen species (ROS)), decreasing inflammation, improving the microbiome and increasing digestive health.
