Excellent for short sleep and extra support while training
I have been taking it for years during periods of high activity and when I get little sleep. I used to suffer from insomnia and learned that if I took it with 200mg of caffeine on the days I didn't sleep, it helped me to have more mental clarity. This effect is only noticeable in case of severe sleep deprivation. Sleep is a thousand times better, but if you can't at that time L-tyrosine helps with caffeine. You also perform better in the gym.

Could be useful for training
It could be useful for training, but for studying it is true that I have not noticed any difference compared to not taking it. I will try other presentations of tyrosine to see how it works.

Health support
Tyrosine is a non-essential amino acid, which means that the body can produce it, but it can also be obtained from food and supplements. It is crucial for the synthesis of proteins, neurotransmitters and hormones, and plays a key role in the production of melanin, the pigment that colors skin and hair.

Info
The crossed-out price or the one shown as "PVPR" on our website is not a value arbitrarily estimated by HSN. This amount strictly corresponds to the official list price recommended by the manufacturer (or by our product development department in the case of own brands) for individual sale in the general retail market.
This information is used solely as an informative reference to allow the consumer to compare our current price with the standard market price suggested for a product of that category and quality.
Why is our price much lower? The large difference you perceive is not because the PVPR is inflated, but due to our business model. At HSN we operate under a Fair Price policy based on our business model with the elimination of intermediaries (Direct-to-Consumer Model).
The PVPR reflects the cost the product would have if it went through the traditional distribution chain (Importer > Wholesaler > Physical Store).
By purchasing on our website you acquire the product while avoiding those added costs. Therefore, the "discount" shows the structural savings we offer versus the industry's standard recommendation.
