Abstract

This study aimed to demonstrate the effect of enhanced Amino Acid (AA) compositions on human cognitive functioning after Covid-19 damaging effect. The research study design included an open, randomized, placebo-controlled trial for 60 days. Participants in the study were measured initially, randomly divided into three groups: people who had Covid in the previous year. people who never had Covid. and placebo. Experimental and non-Covid groups used amino-acid compositions. while placebo group used sugar pills. All people were measured after 30 and 60 days. 70 healthy people aged 35-65. men and women. divided into three groups: 35 people in experimental Covid group, 15 people in non-covid group, and 20 people in placebo group. People in placebo group all had Covid. People in experimental covid and non-covid groups consumed daily specially prepared aminoacidic composition, charged with the radiation of a cold plasma. In the first test Covid groups demonstrated a statistically significant difference with a non-Covid group. After 30-and 60-days results of the experimental Covid group had no statistical difference with the results of non-Covid group. while results of both these groups demonstrated a statistically significant difference with the results of placebo group. The results showed that using AA compositions during the longitude period significantly affected cognitive functions in particular memory, speed of reactions and attention and allow to overcome negative effects of the Covid inflammation.
