Cognizant is a food supplement with sweetener based on Choline, Citicoline and Vitamin B12, which contributes to the normal functioning of the nervous system, normal psychological function and the reduction of tiredness and fatigue. Choline is a choline transporter and precursor of phosphatidylcholine, it has the potential ability to carry out preventive and corrective action on biochemical lesions, which are recognized as having particular value among the pathogenetic factors of the involutional psychoorganic syndrome, i.e. on the reduced cholinergic tone and on the altered phospholipid composition of neuronal membranes. Clinical studies have validated the ability of choline to beneficially intervene on cognitive and memory functions, as well as on the affective and behavioral sphere compromised by involutional brain pathology. Citicoline is a particular molecule with psychostimulant and nootropic activity, i.e. it is able to increase the individual’s cognitive abilities. The use of citicoline is indicated in the supportive treatment of parkinsonian syndromes. Furthermore, citicoline can also be used in the case of cerebrovascular disorders of degenerative, traumatic or atherosclerotic origin, which can lead to the onset of alterations in cognitive functions. The cardio and vaso-protective biological action of Choline is amplified in association with Vitamin B12 antagonizing the deleterious effects of hyperhomocysteine. Low levels of B12 are associated with neurodegenerative diseases, cognitive impairment and also with delayed myelination or demyelination of neurons.
