𝑩𝒊𝒕𝒕𝒆𝒓𝒔 are a tool that can be used to improve gut health, bile and other organ support via the vagus nerve and stimulation of digestive acids, enzymes, bile salts and more. But what are bitters?


Medical definition of bitter principle: any of various neutral substances of strong bitter taste extracted from plants.


Bitters a are varied group of plant constituents or molecules with a pronounced bitter taste – these are the active ingredients of the plant. Bitter herbs are often hepatics & cholagogues (more on this in our biohacking Facebook group), and must be ‘tasted’ to produce these effects.


The bitter principles; The bitter principles work by stimulating the bitter receptors of the tongue and increasing saliva secretion. Thus, it is always advisable to taste and chew the herbs. Sorry your ACV pills and gummies are no good!😉


The taste or sensation of bitterness is directed primarily by the vagus nerve to the central nervous system, leading to various physiological effects – bitter tastes stimulate the vagus nerve in your tongue (although this nerve originates in your brain), which in turn signals the digestive system to start getting ready for digestion with the production of stomach acid, bile acids, digestive enzymes and peristalsis if needed. This vagal stimulation also tells the body (and mind) to rest and digest – relax and slow down. 🙏
