L-TYROSINE POWDER
Top with caffeine
I had once taken a caffeine tablet without the theanine and was then awake but far too nervous. You don't get that with the theanine. It definitely has a calming effect and I have now ordered a second one. The only thing that's a bit annoying is the packet, as my fingers almost can't get into the small bag with less and less content

L-TYROSINE POWDER
Good for thyroid function
I am taking it to regulate secondary hypothyroidism. As a criticism I would say that the taste is not very good.

L-TYROSINE POWDER
Valid
I purchased it to make my own pre workout, the packaging is a bit uncomfortable and the closure tends to come off the sachet.

L-TYROSINE POWDER
Very good against anxiety.
I'm taking it every day on an empty stomach and I've noticed a significant improvement in anxiety and the desire to eat all the time. I'm satisfied. It also has no taste and dissolves well.

L-TYROSINE POWDER
No additives
I bought it for the first time on the recommendation of my nutritionist to recover from a bad season of illness. I really like the fact that it has no additives. The taste goes unnoticed.

Tsh
I hope it helps to regulate the tsh a little when it is just at the limit of normal values.

Long-term supplement
It must be taken in a sustained manner over time and together with a balanced diet and ordered activity. It helps for the most stressful seasons.
