"Tyrosine taken in the morning gives me better moods during the day, I don't dip so low in the afternoons and have a much more even keel approach to the little stresses in life. I miss it when I don't take it for a few days."
"this had a bad effect on me, left me very "jumpy". i tried it for more than a week and gave up because my body just wasn't adjusting to it. not saying it's a bad product because it seems to work for other people, it's just not the right product for me."
"I like to take this in the morning, especially after taking 5-HTP (NSI brand) the night before. It gives me a little boost... more natural than caffeine. I've taken this for more than 6 months but not daily."
"These supplements changed my life! I'm feeling better than ever. Great mood, a lot less stress, alert and vital, more selfconfidence. I take one in the morning one hour before breakfast and I feel the effect the whole day long. A super product for a nice price."
"I give this to my son instead of those nasty pills they want to give him at the psych doc. I have a combination that I give him, but sometimes the brain needs a little help and these do the trick. They also made him a little more alert so he could focus during the day."
"One of the benefits of this product is it calms my body and even increases my energy--I mainly take it when I feel tired. I noticed taking this amino acid it seems to suppress my appetite and gives me an increas feelings of satisfaction. I read in a book L-tyrosine may be a good supplement for those trying to lose weight because, theoretically, it may help speed metabolism. I know it gives me an extra energy lift."
