Magnolia bark contains honokiol, which modulates GABA-A receptors similarly to mild benzodiazepines. Adding exogenous GABA compounds the sedative effect.
Severity
Caution
Evidence
limited
Timing
Evening only, low doses.
How it works
Honokiol from magnolia bark is a positive allosteric modulator of GABA-A receptors; exogenous GABA adds to inhibitory neurotransmission.
Honokiol's mechanism is similar to benzodiazepines but much weaker. Oral GABA's CNS penetration is debated, but even peripheral effects may contribute to sedation. Daytime drowsiness is the primary concern.
What to do
If combining, take in the evening only. Start with low doses. Avoid before driving or operating machinery.
