There are many similar studies with the above quote that cites this 1971 study that you can't seem to find anymore (if anyone knows how I would be happy) Seeds as sources of L-dopa - PubMedPrevious studies reported that, MP contains L-DOPA and 5-hydroxy tryptophan (5-HTP) as a major constituent with higher concentration in seeds [21,22].
I can't seem to find anywhere about how much 5-HTP there is in the seeds. If it would be significant enough to cause an effect.
Investigation of noradrenaline and serotonin mediated antidepressant action of Mucuna pruriens (L) D.C seeds using various experimental models - Advances in Traditional Medicine
The effect of antidepressant treatments have traditionally been discussed primarily in terms of effects on noradrenergic and serotonergic systems. Mucuna Pruriens L (D.C) (Leguminoseae) is widely used in Indian folk medicine in variety of disease conditions. Based on nervous protective action of...

There was another study that showed increased dopamine, serotonin and norepinephrine levels after chronic treatment, and that study linked the increase with neuroprotective properties of MP. 14 days in this study kind of seems short for such an effect to take place, it was done on mice though. Anyone wanna chime in? Do you guys think a Mucuna Pruriens seed extract will directly increase serotonin?As shown in Table 6, significant (p<0.001) increase in brain serotonin concentration was observed with 14 days MPE (200 mg/kg, p.o.) treatment as compared to control.
