what is tyrosine ?
Tyrosine is a naturally occurring nutrient and the building block for dopamine, the brain’s reward and pleasure chemical [1].
Before it becomes dopamine, tyrosine undergoes a conversion process in the brain. Tyrosine is also the precursor to your thyroid hormone [6].
what is dopamine? Your motivation molecule
Dopamine is a neurotransmitter naturally produced in your body. Feeling alert, a sense of accomplishment or the momentum to get things done are all part of dopamine's role. Your dopamine levels are influenced by:
- Dietary intake of phenylalanine or tyrosine [7]
- Functioning of your brain’s dopamine receptors [8,9,10]
- Genetics [11,12,13]
- Chronic stress [14]
dopamine benefits
Motivation & alertness
A study found that in the brains of highly motivated individuals, there was an increased release of dopamine in the areas that involve reward and motivation [15].
Reward & pleasure
When dopamine levels are high, you may experience more pleasure from activities and are more likely to feel the reward after completing a task [4].

what releases dopamine?
Before you can release dopamine, ensure your body has enough tyrosine, as adequate production is necessary to reap its effects.Dopamine gets released when you're anticipating a positive outcome or actual physical reward, helping you feel motivated to seek more of those rewarding outcomes [16] including:
- Listening to music - The anticipation of and enjoyment from music releases dopamine in your brain's system for decision-making, habit formation and reward processing [17]
- Exercise - an extensive review of 15 studies found that physical activity affects dopamine concentrations in the brain[18]

I love this product. It is NOT a stimulant... it just get's whatever neurons have been in the way - out of the way, so that I can get things done.
As just starting taking tablets,to early to say.
As first time using,will wait to give review
Seems to be a great product but would like some guidance on if it should be taken with or without food.
I weight 107 lbs. and I'm very active. I've been taking 500 mg with success, however, my first day with the 800 mg is not going well. My vision is off; It's blurry.

The symptoms you have mentioned might be indicative of an underlying health condition, and we would recommend that you speak to your GP if these symptoms persist.

I've only taken two tablets so far. So I can’t say anything
Good quality product but after 4 days they were causing me "fatigue" so now asking for refund.
I tried it for about 2 weeks but had to stop due to adverse side effects of fatigue and nausea. The fatigue was the real killer.
Store owner replied: Hi Cindy, Thank you for your feedback and I'm sorry that you have been struggling with fatigue and nausea. Please see to your GP if symptoms persist as they might be indicative of an underlining health condition. [Christine - brain feed customer services]
