GNC L-Tyrosine 500mg, Nervous System Support, 60 Vegetarian Caplets | Non-Essential Amino Acid That Fuels Skeletal Muscles and Supports Protein Synthesis, Kosher and Vegetarian Formula

this brand works best for me i have tried other brands and they didn't work like gnc does (FOR ME)

Love this

I’m completely indifferent to these. Nothing bad happened, but nothing great either. I’m not sure if I’ll order again.

I didn’t even know L-Tyrosine was a “TikTok trend” a few years ago, I just know it’s changed my life for the better. I’ve been taking L-Tyrosine for about 7 months now, and it has made a dramatic difference in my daily functioning. For those who aren’t familiar: L-Tyrosine is a direct precursor to dopamine. Most people naturally produce and regulate dopamine just fine. But for some, like me, genetic mutations can disrupt this balance. I have the Val/Val COMT gene mutation, which causes my body to break down dopamine too quickly, leading to dopamine deficiency in my prefrontal cortex. This has a huge impact on my focus, motivation, and especially my energy levels. I also have ADHD and take Adderall daily. But here’s the thing: not all ADHD cases are caused by dopamine deficiency. Some people with ADHD have normal dopamine levels, and some even have the opposite COMT mutation (Met/Met), which slows dopamine breakdown and leads to higher dopamine levels in the prefrontal cortex. In my case, my dopamine levels were too low… SO low that I was struggling with debilitating excessive daytime sleepiness. I would sleep for literal DAYS. Adderall helped at first, but eventually wasn’t enough on its own. That’s where L-Tyrosine came in. When Adderall started struggling to do its job, L-Tyrosine stepped in to help. It’s been a perfect companion, helping to support dopamine production and restore balance. I’m now able to stay awake during the day, focus better, and actually get things done. My routine: • Adderall first thing in the morning • One L-Tyrosine an hour later • A second L-Tyrosine about 6–8 hours later for that final stretch of the day IMPORTANT HEADS UP: In the beginning, L-Tyrosine might make you feel hot, super thirsty, or give you a mild headache. THIS IS TEMPORARY! It goes away for most people—unless your body doesn’t need extra dopamine. If you’re not dopamine-deficient, L-Tyrosine can do more harm than good. It can raise blood pressure and increase anxiety, so it’s worth doing your research or speaking with a healthcare provider before diving in. Price-wise, I think it’s a steal at about $20 a month for something that gives me this much life back. The tablets are a little large and uncoated, which can make swallowing difficult… so I let them sit in my mouth with some water for a few seconds before swallowing to make it easier. Bottom line: This supplement gave me my life back. I’m so grateful for it.

Tick tock made me buy it...when I take it I do notice that I have more energy.

Did absolutely nothing for me. Total waste of money. Won’t buy again. Don’t believe the hype. It was a TikTok trend, they do nothing!

I liked it made me feel good , but I feel like it dehydrated me

Gave me a headache. I didn’t feel more energized.
