Product Information

Caffeine is metabolized in the liver by the cytochrome P450 oxidase enzyme system, in particular, by the CYP1A2 isozyme, into three dimethyl xanthines, [188] each of which has its own effects on the body:

For the general population of healthy adults, Health Canada advises a daily intake of no more than 400mg. [72] This limit was found to be safe by a 2017 systematic review on caffeine toxicology. [73] Children Caffeine is also a common ingredient of soft drinks, such as cola, originally prepared from kola nuts. Soft drinks typically contain 0 to 55 milligrams of caffeine per 12 ounce (350mL) serving. [232] By contrast, energy drinks, such as Red Bull, can start at 80 milligrams of caffeine per serving. The caffeine in these drinks either originates from the ingredients used or is an additive derived from the product of decaffeination or from chemical synthesis. Guarana, a prime ingredient of energy drinks, contains large amounts of caffeine with small amounts of theobromine and theophylline in a naturally occurring slow-release excipient.

Caffeine does not appear to be a reinforcing stimulus, and some degree of aversion may actually occur, with people preferring placebo over caffeine in a study on drug abuse liability published in an NIDA research monograph. [114] Some state that research does not provide support for an underlying biochemical mechanism for caffeine addiction. [2] [115] [116] [117] Other research states it can affect the reward system.

If you have dry skin or are looking to boost the benefits of under-eye patches, Caglia recommends going a step further with your skincare regimen and incorporating a facial tool. "I recommend using what's referred to as an infusion driver, like a facial roller or Gua Sha. I usually reach for my Rose Quartz Rosebud Eye Treatment Set on clients, as its very cold naturally, which helps stimulate blood flow and ultimately minimize puffiness while penetrating the eye area even further."

While caffeine does not directly bind to any dopamine receptors, it influences the binding activity of dopamine at its receptors in the striatum by binding to adenosine receptors that have formed GPCR heteromers with dopamine receptors, specifically the A 1– D 1 receptor heterodimer (this is a receptor complex with 1 adenosine A 1 receptor and 1 dopamine D 1 receptor) and the A 2A– D 2 receptor heterotetramer (this is a receptor complex with 2 adenosine A 2A receptors and 2 dopamine D 2 receptors). [169] [170] [171] [172] The A 2A–D 2 receptor heterotetramer has been identified as a primary pharmacological target of caffeine, primarily because it mediates some of its psychostimulant effects and its pharmacodynamic interactions with dopaminergic psychostimulants. [170] [171] [172] Amphetamines increase dopamine/norepinephrine release and inhibit their reuptake, leading to central nervous system (CNS) stimulation

According to the International Classification of Diseases (ICD-11), cases of very high caffeine intake (e.g. > 5 g) may result in caffeine intoxication with symptoms including mania, depression, lapses in judgment, disorientation, disinhibition, delusions, hallucinations or psychosis, and rhabdomyolysis.
