make sure to balance it with other aminos to prevent dopamine depletion. 5-htp works wonders if mixed with whey protein since whey on it's own tends to raise dopamine / Noradrenaline but not serotonin.. 5-htp balances it out.. by having the opposite effect, there is also a synergy between 5-htp and other aminos where one requires the other to work. deep things going on, the body is a complex beast. I'm sure there are situations where 5-htp on it's own is warranted. but in most cases it should be mixed with other aminos. whey is perfect. take my word for it folks.

I've tried Natrol 200mg time release, it was good .. My low mood seemed to be replaced by light heartedness,... Thought I try another brand Doctors Best, doesn't work for me.. I get nausea each time I take it .. Now I'm trying Natrol 100mg time release ..
