I kinda like these! I take one on a empty stomach a few minutes before exercising and I feel it gives me a burst of energy and my mental focus has improved! To me is is better with taking with htp but it will alright on it's own.It is something I would purchase again and iHerb is #1 in my book!

Very Good

This product is really good. It bought me up from where the RX medication left me. It did what it was made for so well that I have stopped taking my thyroid RX completely.

This is a fantastic product if you have slow thyroid. It gives me just the right amount of energy without making me jittery.

This product was recommended along with 5-HTP for help with ADD symptoms of not having good focus. I am tremendously happy. It works!

Have been taking this for 2 yrs along with other supplements for depression. Now foods is excellent quality. Take it on an empty stomach and wait 1 hr to eat. I take it first thing in the morning.

Works Great

I purchased this and Rhodiola to use for an anti-stress protocol and I can definitely feel a difference. My stress isn't gone completely but I feel like I'm handling stress much better.

They seem to be working

I feel like I have a better outlook and don't feel so stressed. I feel happier so I'm guessing that they do what they say they do - give you some of that good ole dopamine! :) I have also been exercising more without complaint cause I'm just feelng good.

Awesomeness in a Bottle

Posted by 5135912271604025277 on Oct 15, 2013

I was diagnosed this year with depression, anxiety and bipolar and did not like being the medications. I discussed with my doctor coming off of the meds and though the dosage was reduced I stopped taking them all together. Though my triggers were not there and I felt I was coping ok, I got feedback from those around me that I still didn't appear present. I had a lack of interest in things, suffered from the blues and felt a lot of low moods. In my reading on natural supplements I found L-Tyrosine and have been taking it in the mornings before breakfast. At night I take 5-HTP 50mg, I felt the difference within the first week! I'm more balanced with my moods, sleep well and even have the motivation to get into my exercise routine. I do feel more mentally alert and ready to get back into activities I previously lost interest in (of course during this time, I also started going back to my therapist).I strongly recommend these products and advise not to mix with prescription drugs.
