Its pleiotropic beneficial effects, significance as a possible cytoprotection mediator, neurotransmitter, eye therapy, tendon, muscle (striated, smooth, and heart muscle), junction (neuromuscular, osteotendinous, myotendinous, muscle-to-bone attachment), angiogenesis, and NO-system functions, and its considerable role in braingut axis and gutbrain axis functioning were presented in several reviews given by our group [3,4,5,6,7,8,9,10,11,12,13,14,16,17,18,19,20,21,22,23,24,27,28,29,30,31,32,34,37,39,40] and other groups [1,2,15,25,26,33,35,36,38], as well
