Good enough for me

Posted by Reviewer3177127 on Mar 04, 2012

I take tyrosine at a fairly high dose (6000mg) to treat low energy and apathetic depression. This product works great for me. Buying it in bulk makes sense if you are taking a high dose like I am. But if you're just wanting to try the brand out, or try tyrosine in general, it's better to get a smaller quantity. Tyrosine doesn't agree with everyone's system. I've heard comments that the quality of amino acid supplements varies wildly across brands. I have only tried a few brands- NOW and Sisu. Both were good enough for me and my needs, and about the same in strength/effectiveness, etc.

this seems to be a real mood lifter and energizer,w/o the strong ups and downs of energy drinks, tripple expresso latte/chais etc.....

Just started it. Supposed to be good for the thyroid. Time will tell but so far it seems to have had a positive effect. One should do their own research on this specific nutrient.

I was looking forward to relieving my eternal tiredness with this amino acid, but it only aggravated the state, and left me even more tired and stiff in the shoulders and neck area.

Great for mental clarity

I started taking this when I started lifting weights, but I found that it helps my brain stay sharper.
