The Sleep Stack is Thorne's three-bottle protocol for people who want measurable sleep improvement without leaning on a single mechanism. PharmaGABA-250 supports the calming neurotransmitter system, Melaton-3 delivers a low practical dose of melatonin to nudge sleep onset without receptor blunting and Magnesium Bisglycinate provides the highly-absorbable magnesium form that shows up in the muscle-relaxation and nervous-system literature.
Taken together they work on different sides of the sleep problem at once, which is why the stack outperforms any single bottle in real use.
