Tyrosine is an amino acid necessary for the formation of neurotransmitters like dopamine, adrenaline and norepinephrine. This ingredient is widely used to aid wakefulness without the use of stimulants such as caffeine and could prove to be very helpful in combating stress and depression.
Tyrosine supplementation has been shown to increase cognitive performance during times of stress and energize people with depression.
Despite its theoretically stimulating effect, taking tyrosine is very safe and several studies have used doses well in excess of 5000 mg per day.
L-Tyrosine can be a great addition to your pre-workout formula or just used to increase focus and energy.
