iHerb Customer Reviews

Change in mood will occur with l-Tyrosine

Posted by iHerb Customer on December 22 2017 | Verified Purchase

I feel the need to let others know of the side effects of this amino acid, l-Tyrosine. When taken at a high dose (such as 1,000mg-2,000mg) it can cause a negative change in mood. The effects l-Tyrosine had on me were agitation, intense focus and alertness, and increased bodily energy. I would recommend taking l-Tyrosine at a low dose such as 250mg each day for increased focus and energy without the negative side effect of aggression and agitation.

Mood enhancement

Posted by iHerb Customer on November 18 2017 | Verified Purchase

Tyrosine has helped to improve my depressed mood associated with menopause to the point where I do not need an antidepressant. It's worth the expense!

Thanks for your feedback!

Amazing quality, trusted brand, This is a very good brand of tyrosine. Consistant results, works great. Be careful not to over do it taking tyrosine. More in this case is not better. Skip days and adjust your dosage downward once your dopamine levels are up to where they should be. If your levels are too high you will become wired and on edge, you need to skip days if this happens, highly recommended!!
