N-acetyl L-tyrosine supplements are usually taken by sportspeople to combat fatigue (physical and mental) and to increase resistance to stress. The scientific literature reports no risks associated with such use but does not recommend it for those with Parkinson’s type disorders or thyroid problems.
The recommended dose is around 600mg of tyrosine a day (2 capsules), to be taken at the beginning of the day when the rate of catecholamine synthesis in the brain is at its highest.
Tryptophan is an essential amino acid, and in particular, a serotonin precursor. Unlike tyrosine, tryptophan is found in plant-source foods because animals are not able to synthesise it. However, both these amino acids are involved in producing neurotransmitters, so it is worth considering combining tyrosine supplementation with that of tryptophan.
