Dr Daniel Amen recommends it for several uses. It is safe if you use if for the right reasons IMO. You can gget Dr AMens books to read the details and understand the use.

Dr Atkins recommends a number of nutritionals that are helpful for a variety of specific issues. I have recently (4-6 weeks ago)started L- tyrosine and will never go back to living without it. THis increases dopa mine and norepinephrine; it also deals with stopping the urge to binge. It has worked for me on both accounts.

5HTP is one that I have looked at and after careful consideration I have decided not to use it at this time as it increases seratonin and I need to bring up the levels of dopamine to balance the seratonin levels. It sits on the vitamin shelf, so I have faith in its ability to work. Dr Amen has not steered me wrong yet.
