precursor for dopamine and thyroid hormone

Dopamine is responsible for the feeling of well-being and prevention of depression. As there are no drugs available to boost this neurotransitor for non-Parkinson's patients, tyrosine is the only substance available to take to boost these levels. (and the n-acetyl form has shown to be most effective). Most commonly depression is related to a serotonin deficiency, but the second most common neurotransmitter assisting depression is dopamine. If 5HTP doesn't help (to raise serotonin levels) then the logic next step is to try tyrosine. It's best taken on an empty stomach. It's good to boost thyroid hormone in patients with hypothyroid as well.

These will really wake you up! I actually get some palpitations if i take too much as it's strong. The N-Acetyl form of Tyrosine is so much more bioavailable, and is alot stronger than normal L-Tyrosine at a lower dose, therefore you don't need as much to feel the effects. It definitely helps focus and alertness through boosting norepinephrine and dopamine. Excellent product.

More Powerful than Regular Tyrosine, Sometimes Too Much

4 people found the following review helpful

I purchased this product after having used Jarrow Formulas regular L-Tyrosine. I noticed a significant difference when using this product compared to the original. This product produces a much stronger effect and it sometimes felt a bit unpleasant, like I was a bit wired. I will probably use the rest of this bottle and switch back to the regular L-Tyrosine in the future.

I use this with 4 other supplements for my bipolar cocktail and this brand seems better than others I have tried. This is a key for me and my brain.
