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 may 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

Questions & Answers

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]

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 [4]

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.

I haven't tried this product before. What if I don't like it?

Because we manufacture this product ourselves, we believe that the onus is on us to produce a high quality product that you're going to love.

That's why we have our 110% Guarantee. Basically if you try it and you don't love it, just reach out to us. You can receive a 110% store credit, or a full refund.

Wow, I am a new customer and am super impressed with this company. Superior customer service and the products are of excellent quality and taste amazing! I bought several different products and flavours. I have tried numerous other (disappointing) brands and am glad I tried this one. I will stick with them for sure! I love that they are an Aussie brand and have reasonable/competitive prices too. Highly recommended.

Hard to give a very accurate review yet as I only purchased the product yesterday
I used it today it appears to be a good tyrosine product but will have to use it for a few more weeks before giving a definitive review
I’m always happy with the Aminoz own brand products, so let’s hope this is the same quality

Our reply:

Thank you for sharing your initial thoughts on Amino Z L-Tyrosine, Cindy! I appreciate your honesty and understand that it's early in your experience with the product.

It's great to hear that your first impression is positive and that you've had a satisfactory experience with other Amino Z own brand products in the past.

As you rightly mentioned, it often takes a few weeks of consistent use to fully assess the effects of a supplement. I'm glad you're giving Amino Z L-Tyrosine a chance and is looking forward to hearing more about your experience in the coming weeks.

If you ever have any further feedback, questions, or insights to share, please don't hesitate to reach out.

Product is as advertised. I use a micro scale to measure proper dosage/serving size as the scoop provided in a bit ambiguous
