L-Tyrosine improves concentration and focus
Researchers have found anecdotal evidence that food is used by some creative people to improve concentration and depth of thought. This anecdotal evidence was tested in a study using L-Tyrosine.
L-Tyrosine is an amino acid present in many foods, and is a precursor to the catecholamine Dopamine. Catecholamines are a class of neurotransmitter. Dopamine is involved in the cognitive functions of problem solving, attention and memory.
In this study, the effect of oral L-Tyrosine supplementation on creative thinking was tested. 32 participants were tested for improvement in two styles of creative thinking– divergent thinking, usually referred to as brainstorming, and convergent thinking – more commonly known as focus or concentration.
Participants took either 2 grams of L-Tyrosine or a placebo with orange juice. Those who took the L-Tyrosine performed better in convergent thinking tests – in other words, L-Tyrosine improves concentration and focus. There were no performance changes for the divergent thinking tests.
So L-Tyrosine may assist in achieving goals in many areas of life that require convergent thinking – including academic, career and sporting endeavours.
