Well&Well has created this amino acid in TYR Tyrosine capsules to stimulate and provide extra help in the production and synthesis of thyroid hormones. These TYR Tyrosine capsules function as thyroid hormone precursors. It has also been proven that these capsules from Well&Well stimulate the generation of neurotransmitters such as noradrenaline or dopamine with the help of natural chemicals, with the aim of promoting cognitive functioning of the brain. In this way, they help to reactivate and stimulate the learning process, memory, motivation or reward in the face of pleasurable stimuli, such as humour or sex. It is increasingly becoming a complement to your normal activity in times of physical or mental stress, but also for people with thyroid hormone production problems.
