Tyrosine enhances cognitive performance, energy, and alertness, and improves memory after sleep deprivation.

Tyrosine is a conditionally essential amino acid which can come directly from the digestion of dietary protein. Common food sources include dairy, beans, whole grains, meat, and nuts. If intake is insufficient, tyrosine can be formed from the essential amino acid phenylalanine using a tetrahydrobiopterin reaction. Tyrosine itself is a precursor to several neurotransmitters including dopamine, epinephrine and norepinephrine. It is also needed to create thyroid hormone and melanin skin pigments. Within the metabolism of tyrosine to form neurotransmitters and other hormones, there are several important nutrient cofactors involved including vitamin B1, vitamin B6, tetrahydrobiopterin, copper, vitamin C, among others.

Tyrosin is the non-essential amino acid precursor for dopamine, norepinephrine and epinephrine. Tyrosine hydroxylase converts tyrosine into the dopamine precursor L-DOPA; BH4, Vitamin D and iron are cofactors for that enzymatic activity.

- A higher protein intake or supplementation results in increased levels.

- Low protein intake or inflammation can lead to lower levels.

- Nutrient cofactors of tyrosine pathways include BH4, non-heme iron, vitamins B6 and B3, copper, niacin, vitamin C, magnesium, and SAMe.

- Elevated tyrosine is associated with a higher risk of type 2 diabetes and gestational diabetes and a higher body mass index.

- Tyrosine-supplementation effects on cognition vary – unfavorable effects were noted on working-memory performance in older adults.

- Higher tyrosine was related to better cognitive skills in younger adults.

- Urine and blood tyrosine were noted to be lower in depression.

Tyrosine is a non-essential amino acid derived from phenylalanine, and it plays a pivotal role in the body’s ability to generate catecholamine neurotransmitters — dopamine, noradrenaline, and adrenaline. These compounds regulate motivation, alertness, attention, and stress response, making tyrosine a critical link between dietary amino acid balance and neurotransmitter function.

On the Neurotransmitter XL panel, tyrosine serves as a key marker for assessing catecholamine precursor availability, stress metabolism, and neurotransmitter synthesis capacity. Low or high tyrosine levels can indicate issues with phenylalanine conversion, cofactor status, or metabolic demand from chronic stress and inflammation.

Tyzzerella, a genus of bacteria identified in comprehensive gut tests, is part of the intricate ecosystem of the human gut microbiome. Though not as widely recognized as some other bacterial genera, Tyzzerella plays its own unique role in gut health and functionality. The presence and levels of Tyzzerella, along with other bacterial species, are analyzed in gut tests to provide a deeper understanding of the microbiome's composition and health.

The specific role of Tyzzerella in the gut is an area of ongoing research, but like many gut bacteria, it's believed to be involved in the breakdown and fermentation of dietary components, contributing to overall gut function. The bacteria in the Tyzzerella group may participate in the metabolism of certain carbohydrates and fibers, aiding in the digestive process and the production of beneficial metabolites. These metabolites, including short-chain fatty acids (SCFAs), are crucial for maintaining gut barrier integrity, modulating the immune system, and providing energy to colon cells.

The marker Tyzzerella 4 is a fascinating and important component when it comes to understanding gut health. This marker is part of a comprehensive test offered by Vibrant Wellness that evaluates the microbiome, or the community of bacteria and other microorganisms, living in the human gut. Tyzzerella 4 refers to a specific type of bacteria that has been identified and included in the panel for its potential significance in the digestive system's health and overall wellbeing.

In the context of the Gut Zoomer panel, the presence, absence, or abundance of Tyzzerella 4 can provide valuable insights. For instance, certain levels of this bacterium might be associated with health conditions, digestive function, or the effectiveness of the gut barrier. The Gut Zoomer panel aims to give a detailed snapshot of the gut's microbial landscape, enabling healthcare providers to tailor recommendations for diet, lifestyle, or treatment to improve gut health and, by extension, general health.
