May have helped with my panic attacks

For a couple of months I was getting these strange....mild panic attacks. No palpitations but an overrarching feeling of being overwhelmed. My diet is great, I exercise and they just came and went without much reason. My trainer recommended L tyrosine to me and I gave it a shot. It's easy to taste and digest and I found the benefits of basically stopping these strange attacks I had for a couple months. Recommend

Good focus and motivation

I use around 500mg of this powder in my homemade preworkout and it gives a nice focus and motivation boost compared to a version without it. Tyrosine is a building block of dopamine wich is an important neurotransmitter for our brain's reward system. I recommend this to anyone how wants to get a mild boost of motivation and focus for their activities.

Excellent! Just perfect!

I use Tyrosine in powder as a pre-workout because I don't tolerate most of additional ingredients they usually put with, along with Now taurine pure powder and Ginseng. L-Tyrosine helps me a lot to reduce (and actually stop completely) the occurrence of brain fogs due to Multiple Sclerosis and Ehlers-Danlos syndrome. My mental fatigue is better and I use it especially on days I need to use mental energy (like read, understand important stuff..). It made the complete difference in my independence because I don't need home care services anymore (my cognitive impairments include executive dysfunction, I need help to figure the steps to accomplish any task like washing myself or dress up). A life saver for my brain!

Dopamine

I watched youtube video on how this supplement can help lower prolactin and also increase dopamine. I bought to try but seems to always feel tired after a few hours of taking it. Not sure why? hope to continue experiment

Happy Pill

I use this sublingual and can feel the affect immediately. because it's a powder I cut down my consumption from pills. usually one scoop 250 mg is good enough for a whole day. some days I'll do two depending on how I feel. No taste or flavor under the tongue.

Great support for focus and mental clarity

Great quality L-Tyrosine powder from NOW Foods. I take it for mental clarity and focus, and it really helps with concentration, especially during busy or stressful days. The powder dissolves easily in water or juice, and there’s no strong taste. I also like that it’s pure, with no unnecessary additives. Definitely a staple in my supplement routine!

Crucial when needed

So much in the neurotransmitter pathway follows Tyrosine—Dopamine, Norepinephrine, and Epinephrine have a huge influence on mood and bodily functions. So if you’re low on Tyrosine for some reason, this supplement could be a big help as you work to understand and address underlying causes of the deficiency.
