N-ACETYL L-TYROSINE POWDER
Excellent result
For me it is excellent and basic in my supplementation. It allows me to maintain stability in my emotional state even when there are many physical and mental demands.

Pre-training
Dopamine support, concentration, raises body temperature and therefore energy consumption, I recommend adding to pre-workout in the morning.

Before I used to take L-tyrosine and did not notice anything and when I started taking this acetylated form I noticed more energy and concentration.

Valuable
It is one of the supplements that I have the highest esteem for the activation it gives me in the morning, to go to train without breaking my fast and also help to reestablish my circadian rhythm.

N-ACETYL L-TYROSINE POWDER
Excellent, but not the same packaging as the image.
Everything perfect, very fast shipping and in excellent condition. Only thing that caught my attention was not receiving the same packaging of the image, this is a white packaging instead of gray so I thought there was an error in the shipment, fortunately not. The closure works perfectly. The taste is a pleasant acid, I dissolve it in green tea or in little water since the daily dose is very small. I started 3 days ago so I can't really evaluate the effectiveness. The price I got it at almost 10 euros in promotion so I took advantage of 2 packs to maintain consumption over time, it would be excellent that this is the standard price! We will see its effect!

N-ACETYL L-TYROSINE POWDER
Less efficient than regular tyrosyna
Studies support that L-tyrosine supplementation is superior to NAT. Oral L-tyrosine supplementation increases plasma tyrosine levels by 130-276%, whereas intravenous NAT provides only a 0-25% increase. Due to the inefficient conversion of NAT to tyrosine, up to 60% of NAT is excreted in the urine unchanged, meaning that it was never converted to tyrosine. Although NAT is more soluble than L-tyrosine, it is an inferior form of tyrosine supplementation. So why do companies use N-acetyl tyrosine instead of L-tyrosine? Because it dissolves better in water and they have not adequately researched the subject.
