NOW FoodsSupplements, L-Tyrosine 500 mg, Supports Mental Alertness*, Neurotransmitter Support*, 120 Capsules

Excelente Producto. Soy Hipotiroidea, tengo Hashimoto y Sjogren, MTFHR 6c 77 t heterocigodo y tengo un cerebro muy activo pues soy HSP y mi desgaste mental en el día necesita fortalecerse.Lo tomo no para tiroides pero si como apoyo a mis neurotransmisores ya q es un aminoácido precursor clave en la síntesis de varios neurotransmisores importantes. Es como la “materia prima” que el cuerpo utiliza para fabricar ciertas sustancias que regulan el estado de ánimo, la motivación, la atención y la respuesta al estrés. Lo tomo solo dos veces al dia en la mañana 30 mins antes del desayuno temprano y luego en el almuerzo mas tardar 1 pm ya q en la tarde no favorece..Realmente quisiera una dosis un poquito mas baja como de 250 mg pero no he encontrado.La L- Thyrosina no es tan efectiva para tiroides pero si Favorece la producción de neurotransmisores bajo demanda, especialmente en condiciones de:• Estrés• Privación de sueño• Sobrecarga cognitiva• Fatiga✅ Mejora el rendimiento mental bajo presión (por eso se estudia en soldados y pilotos).✅ Puede apoyar el estado de ánimo y la motivación, especialmente si hay bajos niveles de dopamina o norepinefrina.⸻¿Cuándo podría no ser recomendable?• En casos de hipertiroidismo, porque también es precursor de hormonas tiroideas.• Si hay ansiedad severa, puede aumentar un estado de hiperactivación.• En personas con trastornos debe consultar con un mèdico.

I don't really know how I even stumbled upon these, but one reviewer wrote about how it helped with ADHD. So I tried them, and YES....they really helped me. I am now on bottle number 3. LOVE THEM!

take these every morning as part of my routine. Not sure exactly how they work, but I do feel a bit more awake and focused since I started using them. Simple capsules, no side effects so far.

I was pleasantly surprised by the initial results with L-tyrosine. Within the first few days, I noticed a clear improvement in focus, mental clarity, and overall mood. It provided a subtle yet effective boost that felt natural and helped me stay productive throughout the day without any jitters or crashes.However, after continued use, I observed that the effects began to diminish noticeably. It seems that my body quickly adapted to the supplement, and the initial benefits were no longer as pronounced. While it may still offer support at a baseline level, the initial sharpness I experienced was not sustained over time.This could still be a worthwhile supplement for short-term use or occasional support, but for long-term daily use, the diminishing returns are worth considering.

These definitely help to boost my Dopamine and make me feel happier and more energized. I pop one on an empty stomach right when I wake up and another with my coffee about an hour later. Just remember to get enough of the other amino acids from protein throughout the day too, to avoid any amino acid imbalances!

L-tyrosine may reduce serotonin with long term use . Any time used more than a week depression like symptoms occur.

Noticing a change in awareness and energy levels. Working well as a supplement. The price and quantity is hard to match.

Works just as it should. I’ve been taking NOW Foods L‑Tyrosine 500 mg to support mental alertness and overall focus, and it delivers. The capsules are easy to swallow and don’t upset my stomach. I’ve noticed sharper concentration during busy workdays. Definitely a product I’ll reorder.
