Dietary supplements for cognitive function improvement: control of amino acid levels. Livro de Resumos IJUP - 7º Encontro de Investigação Jovem da Universidade do Porto, p. 493. ISBN: 978-989-746-033-3978-989-746-033-3http://hdl.handle.net/10284/9870Neurodegenerative diseases affect cognitive functions by progressive and irreversible destruction of brain cells. The medical treatment is often complemented with dietary supplementation in order to suppress the lack of nutrients that is common in these situations. Some amino acids are especially important to prevent or delay the progress of such diseases. For example, tryptophan, tyrosine, and phenylalanine are biosynthetic precursors of important neurotransmitters (serotonin, dopamine, and norepinephrine), and glutamate and aspartate are themselves brain neurotransmitters. The aim of this study was to evaluate the amino acids composition of commercial dietary supplements (n=8) for improvement of memory and cognitive function.engDietary supplementsCognitive functionBrain cellsAmino acidsconference object
