Why we include:
Tyrosine is one of the 20 amino acids found in the human body. Though you can create it yourself by converting another amino acid – phenylalanine – and get it by eating eggs, nuts, and oats, taking supplemental tyrosine can be beneficial for your brain and nervous system health. A team of researchers conducted a review of the existing literature and concluded that tyrosine helped mitigate the ill effects of cognitive stress.
As your body uses tyrosine to create epinephrine and norepinephrine, it might also aid recovery from adrenal fatigue. Dutch scientists noted in the journal eNeuro that tyrosine “is known to improve cognitive performance in young adults, especially during high environmental demands,” and went on to demonstrate how the amino acid also improved signaling in four areas of aging people’s brains.
