Question

Is rhodiolla rosa herb increase the dopamin level ? Is it cross the blood brain bariar ?

Answer 1

Yes, apparently it does stimulate dopamine levels. The herb doesn't cross the blood brain barrier as it isn't lipid soluble, but it does make it more easily accessible for the dopamine to go in. That even surprised me.

Overall, in small and medium doses, R. rosea stimulated norepinephrine (NE), dopamine (DA), serotonin (5-HT), and nicotinic cholinergic effects in the central nervous system (CNS). It also enhanced the effects of these neurotransmitters on the brain by increasing the permeability of the blood brain barrier to precursors of DA and 5-HT.2,23,42,46-49
