Tyrosine Supplementation To Improve Physical And Mental Performance

Gatorade – Tyrosine Supplementation to Improve Physical and Mental Performance.

The Gatorade Sports Science Institute is investigating performance benefits from Tyrosine supplementation.

Key points from their article:

  • Increased dopaminergic and noradrenergic activity in the brain has been associated with feelings of motivation, arousal, reward, and decreased fatigue. This effect has been linked to enhanced performance.

  • Both dopamine and norepinephrine are synthesized from it through a shared metabolic pathway.

  • Since tyrosine and the other large-neutral amino acids (LNAA) share a common transporter across the blood-brain barrier, an elevation in the plasma concentration ratio of it to LNAA increases its uptake into the brain.

  • The increased delivery of tyrosine into the central nervous system may result in higher synthesis of brain dopamine and norepinephrine. However, this relationship may not be straightforward.

  • The existing evidence does not support a benefit of consuming tyrosine to improve exercise performance. Longer-term studies might be necessary to provide a definitive answer.

  • Tyrosine supplementation does appear to consistently attenuate losses in cognitive function when individuals are exposed to challenging environments. As many sporting situations are highly dependent on effective decision-making and the successful execution of fine and gross motor skills, this would be desirable, despite no apparent benefit to physical performance.
