Head to head
5-HTP vs GABA
Both score the same on overall evidence (35/100). The right pick depends on the specific claim and your goal — read them claim by claim.
5-HTP
Weaka serotonin precursor with real interaction risks
Marketing intensity 70 of 100. Evidence strength 35 of 100. Verdict: Overhyped.
Some weak signal for mood and sleep, but the studies are poor - and because it raises serotonin, mixing it with antidepressants is genuinely dangerous.

Limitedcalm in a capsule — if it reaches your brain
Marketing intensity 70 of 100. Evidence strength 35 of 100. Verdict: Overhyped.
Sold as instant calm, but the catch is basic biology: oral GABA struggles to cross into the brain. A few small trials hint at a sleep effect anyway, by unclear means.
