L-Tyrosine – 500 mg, 90 vegan capsules. New, sealed supplement, delivered from iHerb, expiration date until 11.28. L-Tyrosine is essentially a building block from which the body subsequently produces, among other things, dopamine. Our mood, motivation, ability to overcome stress and derive pleasure largely depend on dopamine – it is precisely dopamine that serves as a key element of the brain's reward system. L-Tyrosine helps cope with the stresses we face throughout the day, and also contributes to a more positive mood and higher motivation. 60 GEL
