## Overview

This clean, allergen-free formula supports thyroid health and is rigorously tested under GMP A-rated standards by a trusted family-owned US manufacturer since 1968.

## Description

L-Tyrosine is a conditionally indispensable amino acid required for the production of the neurotransmitters dopamine, adrenaline, and noradrenaline, as well as for the skin pigment, melanin. Noradrenaline (norepinephrine) and adrenaline (epinephrine) are the main actors in the body’s response to acute stress and, along with dopamine, help to support a positive mood and mental alertness. In addition, L-Tyrosine is especially critical for the normal function of the thyroid gland. The L-Tyrosine used in this product is Pharmaceutical grade. Natural color variation may occur in this product.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well!
*by S***. on July 28, 2025*

I keep this at my bedside and take 1 after my alarm goes off, with a full glass of water. I'd usually have 2 or 3 cups of coffee once up but since taking these I only have one cup now. My mind feels a lot sharper and clearer, and without the caffeine jitters!

### ⭐⭐⭐⭐⭐ amazed by the results
*by L***. on October 17, 2014*

I wanted to wait until I had used this awhile before I gave a review to see how the effects last. I was very skeptical when getting this product because I was skeptical that something over the counter could make as big a difference as some people claimed. I researched a lot about its effects and how it works and since it made sense, I thought I would give it a try, but honestly didn't expect much. For years I have suffered from a "foggy head". It doesn't seem to matter if I sleep 8 hours a night, or 4, or 10, I always wake up tired and with brain fog that persists. Along with that, I've also dealt with depression over the years and some major irritability.As I tend to be pretty sensitive to most medications, I wanted to start out with a smaller dose to see how it would affect me. I opened the capsule and dumped half the contents out, then closed it again and took it with a glass of water. I had eaten about an hour before. I noticed some mild effects and that at work I was breezing through things that usually took me a lot longer to do. There was no stomach upset at all. After reading up on it, I saw that its most effective if taken on an empty stomach, but talking anything on an empty stomach makes me nervous as I've had so many meds make me incredibly nauseous if I didn't eat. The next morning I again dumped about half of it out and took it on an empty stomach and noticed a big difference. Within maybe half an hour the brain fog cleared and I felt truly alert for the first time in years with no jitters or stomach upset at all. The effects lasted until the afternoon and I took another half which got me through the rest of a long day at work. That night I slept great, and felt pretty good when I woke up. Since then I take a full one immediately when I wake up and before I eat anything. I've noticed if I eat anything high in protein before I take it the effects are greatly lessened. This is because l-tyrosine and protein use the same transporter to the brain, so it competes with the protein if you have them both at the same time. Taking a full one every morning keeps me alert and focused all day with no nervous energy, no anxiety, no jitters and no crash. I've been on this same dose for several weeks and it still works just as well. This is now a permanent part of my morning when waking up. I was amazed at the huge difference it made in my ability to concentrate, my focus, energy and my mood. It keeps me feeling pretty uplifted and happy. My life seems much better since I started taking this. This is the only brand I've used, so I have nothing to compare it to, but I will stick with this one. If it ain't broke...

### ⭐⭐⭐⭐⭐ Great value for 120 capsules
*by M***N on June 18, 2025*

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.
