QUALITY AND SIMPLICITY
Amino Z L-tyrosine is a pharmaceutical-grade amino acid product. It is required to produce essential substances within the body, such as dopamine. Dopamine is responsible for regulating mood, retaining memory and learning & applying motor skills. L-tyrosine is also largely responsible for regulating thyroid hormone production related to metabolism. Lastly, it is involved in regulating hormones adrenaline and noradrenaline, which control your “fight-or-flight” response (which occurs in response to stressful situations).
With this in mind, supplementing with L-Tyrosine can cause a subsequent increase in these compounds, which is where it derives many of its benefits.
What you can expect from Amino Z L-tyrosine
• May improve mood and feelings of wellbeing
• May improve cognition
• May enhance mental acuity/concentration
• May relieve symptoms of stress
• L-tyrosine (100%)
Below we have answered some commonly asked questions about this product.
What does the research show for l-tyrosine supplementation?
1. L-Tyrosine can support mental performance and concentration in various settings [1,2]
2. L-Tyrosine supplementation may support thyroid hormone production. Recent research has shown that supplementing with higher doses of L-tyrosine (12 grams per day) may increase "T3", the most active thyroid hormone. It also appears to lower another hormone called "TSH", which can be linked to hypothyroidism 
3. L-Tyrosine has also been shown to improve endurance exercise performance. However, this is not due to any changes in physical factors but rather a psychological improvement in tolerating adverse conditions

Do you manufacture this product?
Yes we do. We have our own purpose-built manufacturing facility in Sydney, Australia.
Why is this product so much cheaper than similar products on the market?
Many other brands incur a high degree of costs associated with producing products. It is not uncommon for a product to be produced by a third-party manufacturer and then shipped (or imported) to a wholesaler. The wholesaler then sells to a retail store, who on-sells to the customer. The end result is that often four separate businesses are taking profits at each stage (the brand itself, the manufacturer, the wholesaler and the retailer).
We take a very different approach which allows us to keep our cost structure down and we pass those savings on to you, without sacrificing product quality.
We have our own purpose-built manufacturing plant located in Sydney Australia and we sell directly to you. This eliminates all additional parties from the process, thereby eliminating a lot of unnecessary costs.
The significant cost savings we incur allow us to invest into high quality ingredients while still offering a significantly cheaper final product.
