L-Tyrosine
What is L-tyrosine?
L-tyrosine is an amino acid that can help the body produce important neurotransmitters such as dopamine and noradrenaline. These substances are crucial for various brain functions, especially under stress. L-tyrosine also plays a role in the production of thyroid hormones and melanin, the skin pigment. While the body can normally produce L-tyrosine from phenylalanine, there are situations, such as metabolic disorders or liver disease, in which it may be necessary to obtain L-tyrosine from food.
Sources of L-tyrosine
L-tyrosine can be found in many protein-rich foods. Meat, salmon, chicken egg, pumpkin seeds, walnuts, peanuts, brown rice, cheese and curd can help to supply the body with this important amino acid. These foods can help the body to produce the neurotransmitters and hormones needed for many vital functions.
How does L-tyrosine work?
After ingestion, L-tyrosine can enter the bloodstream and reach its peak within 1-2 hours. It can then remain in the blood for up to 8 hours. It can then cross the blood-brain barrier and be used in the brain to produce dopamine and noradrenaline. This can be particularly useful when the brain is under stress and neurotransmitters are being used up quickly. L-tyrosine can help replenish these neurotransmitters and support cognitive performance.
Safety profile of L-tyrosine
L-tyrosine is considered safe and well tolerated in moderate doses. A daily intake of around 800 mg can be recommended in stressful times or to boost cognitive performance. However, people with certain health problems, such as hyperthyroidism, or those taking certain medications should consult their doctor before taking L-tyrosine. The dose should be individually tailored to avoid possible side effects.
Potential health benefits
L-tyrosine can offer numerous health benefits, especially in stressful situations. It can help maintain cognitive performance and memory when the brain is under a lot of strain, for example during periods of intense mental or physical work or when sleep is lacking. L-tyrosine can also be helpful in cases of depression and Parkinson's disease, as it can support the production of dopamine. In the world of sport, L-tyrosine can help athletes to increase their concentration and alertness before competitions. A deficiency of L-tyrosine, on the other hand, can lead to reduced stress resistance, weakness and a decline in cognitive performance.
L-tyrosine in the longevity context
L-tyrosine could play an important role in the context of longevity by helping to maintain cognitive function. Over the course of a lifetime, the levels of neurotransmitters such as dopamine and noradrenaline decrease, which can lead to cognitive decline and memory problems. L-tyrosine could help to keep these neurotransmitter levels stable, especially under stress, and thus slow down age-related cognitive decline.
By supporting neurotransmitter production, L-tyrosine could also help to reduce mood swings and depressive states in old age, which in turn can improve overall quality of life. By increasing stress resistance and promoting mental performance, L-Tyrosine could help to reduce the risk of neurodegenerative diseases such as Alzheimer's in the long term, thus supporting mental health in old age.
About the ingredient
In the case of L-Tyrosine, we have chosen a further ingredient that meets the USP35 standard and thus fulfills the strict pharmaceutical quality criteria. USP35 stands for United States Pharmacopeia, 35th Edition, which sets the standard for the identity, strength, quality and purity of pharmaceutical ingredients. This carefully selected L-Tyrosine ingredient has a purity of 99.6%. The impurities detected are 0.02% or less of the strict limits of the USP35 standard, which corresponds to exceptional safety and quality.
