Caffeine which inhibit adenosine receptors are important in its effects on behaviour and cognitive function:
This ability results from the competitive binding of caffeine and paraxanthine to adenosine receptors and is of importance in contributing to central nervous system (CNS) effects, especially those involving the neuromodulatory effects of adenosine. Due to the blocking of adenosine inhibitory effects through its receptors, caffeine indirectly affects the release of norepinephrine, dopamine, acetylcholine, serotonin, glutamate, gamma-aminobutyric acid (GABA) and neuropeptides.

Kefir is a good source of natural antioxidants. Studies show antioxidant activity of kefir and suggest this activity is due to the presence of lactic acid, acetic acid bacteria, and yeasts in kefir with intracellular and extracellular metabolites existing in the kafir. Kefir contains kefiran, a polysaccharide associated with lower blood pressure and cholesterol in studies. It’s also loaded with B vitamins and tryptophan, which fend off stress and produce a calming effect. Probiotics found in kefir helps protect against many infections. One such probiotic is Lactobacillus kefir, a probiotic exclusive to kefir. According to studies, Lactobacillus kefir can stop the growth and fight bad bacteria in the body, including E. coli, Helicobacter Pylori, and Salmonella. Kefir is good source of probiotics, which are good bacteria that live on the lining of the intestines and are responsible for important tasks such as immune support, crowding out bad bacteria, and improving digestion and gut health, as well as many more things crucial to good health.

Probiotics in Kefir also aid:

• Nutrient absorption
• Improving diarrhoea from rotavirus and other pathogens
• Restoring balance of microflora in urogenital tracts
• Preventing/managing eczema & psoriasis
