About This Product

  • Supports mental alertness
  • Supports neurotransmitter production

Supporting the sharpness of your mind is just as important as maintaining the strength of your body. L-tyrosine is a free form amino acid that can be converted into norepinephrine and dopamine in the brain—two compounds that can support mental alertness, brain function, and energy.

The Vitamin Shoppe® brand L-Tyrosine capsules are a convenient, once-daily solution to help you flex your mental muscles.

Directions

Take one (1) capsule daily, preferably in between meals.

I like this product of l-tyrosine:
First time using this product and I like it. I rather use a complete amino acids product but none available at this time so I bought an amino acids product and it didn't contain l-tyrosine so I purchased this product.

Excellent for Energy!
Normally I scour comments to see what everyone says because I take everything with a grain of salt. I was reading about this and it has truly worked for me. I have been taking it for 2 weeks. I take it in the morning before I work out or if I don't work out I take it in the afternoon for my afternoon slump. My mind feels clear and awake but not overly stimulated. Before this I was sleeping or at least feeling tired and exhausted and ready to sleep most of the day. This has really helped me. I was skeptical at first but it has helped my mood and my alertness! Please at least give it a try!

caused fatigue
this was recommended to support thyroid naturally, but this product caused immediate feelings of intense fatigue, I had to drive to a meeting and was seriously concerned about my alertness. I compensated with coffee. My mother didn't notice at first when she started taking the supplement, but after a few days, she began to struggle to stay awake at work, very uncharacteristic for her. May not happen to everyone, but in case it does, know your not the only one.

Excellent mental focus and alertness
I take this every morning with my multi and fish oils. It gives me great mental focus and makes me feel much better. I have PTSD and this helps with my anxiety. It also gives me a little pep before my workout.

Works when working night shift
I bought this product and used it as directed. A couple of days after purchasing it, it took effect on the 2nd night for me. It kept me awake and alert without feeling jittery. For those that work rotating 12 hr night shifts, this may be the product for you. Just make sure to check with your health care provider first. Thanks Vitamin Shoppe..

is this for thyroid support ?
A shopper
Is caffiene in this product?
A shopper

Best Answer:  The bottle for this product lists soy-free, gluten-free, and other "free"s but it doesn't list caffeine. However, it doesn't list caffeine as an ingredient, either. Although I am not a company spokesperson, I'm confident that caffeine is not in this product. In many of my various attempts at giving up caffeine, L-Tyrosine is and has been a favorite ingredient for vitality, recommended by many supplement advocates.

Derotha Ann R
Is it safe to take the 5oomg L-Tyrosine at one time? Or should I take a smaller dose? I am looking for something to help balance my moods, naturally. This ia supposed to do it, but 500mg is alot.
Jessica M

Best Answer:  I've been taking this amino acid with a few others for years with positive results. I take these aminos to help control my anxiety and to help improve my memory and concentration. I take 500mg of each amino and a bufferd vitamin C first thing every morning on an empty stomach with no apparent side effects. Hope this is helpful.

Best Answer:  on an empty stomach, first thing in the morning and again in the afternoon. Do not take close to bed time.

Does it help focus?
A shopper

Best Answer:  Yes..I believe if you keep taking this not just buy 1 and stop this will help you stay focused. It seems to be more effective long term. Rather than short
