Comparison
Magnesium L-Threonate vs Apigenin
Magnesium L-Threonate
MIT-developed magnesium that crosses the blood-brain barrier. Shown to enhance synaptic density and reduce 'brain age'.
Apigenin
Flavonoid found in chamomile, parsley, and celery. Popularized by Dr. Andrew Huberman for sleep and CD38 inhibition.

The comparison in plain English
Two pillars of the popular Huberman sleep stack. Magnesium L-Threonate gates NMDA receptors and supports GABA tone via brain magnesium. Apigenin is a flavonoid (from chamomile) that acts as a partial GABA-A agonist and inhibits CD38 (preserving NAD+).
Bottom line
They are complementary and routinely stacked. Magnesium provides the structural sleep-deepening effect; Apigenin provides the acute GABA-A modulation that helps onset. The Huberman stack uses both.
Choose Magnesium L-Threonate if
Sleep depth and overnight cognitive recovery are your priority. 1500mg threonate one hour before bed.
Choose Apigenin if
Sleep onset and acute anxiety reduction are your priority. 50mg apigenin 30 minutes before bed.
