Apigenin and Magnesium Together — Sleep Stack Guide
Apigenin calms the mind through GABA-A. Magnesium relaxes the body through NMDA. Together they address the two most common barriers to sleep — and form the core of the Huberman protocol. Here is how to combine them effectively.
At a glance
- Safe to combine? Yes — complementary mechanisms, no interactions
- Apigenin dose: 50mg — GABA-A calming (mental)
- Magnesium dose: 145mg elemental from L-threonate — NMDA relaxation (neural + physical)
- Timing: Both 30-60 minutes before bed
- Protocol: Core two-thirds of the Huberman sleep stack
Why apigenin and magnesium work better together
Apigenin and magnesium target different barriers to sleep through entirely separate receptor systems. This is what makes them complementary rather than redundant.
Apigenin (GABA-A pathway): Reduces neural excitability — the racing thoughts, mental replay, and cognitive hyperactivity that prevent the mind from settling. This is the "quiet mind" component.
Magnesium L-threonate (NMDA pathway): Modulates excitatory neurotransmission and supports muscle relaxation. This addresses both the neural transition to rest and the physical tension that can interfere with comfort and sleep onset.
Together, they cover the two most common sleep barriers: a mind that will not switch off (apigenin) and a body that will not relax (magnesium). The Huberman protocol includes both for exactly this reason.
Which magnesium form to pair with apigenin
Magnesium L-threonate (Magtein) — best for sleep stacking: The only form clinically demonstrated to cross the blood-brain barrier effectively. This means it acts directly on neural tissue, not just on peripheral muscles. For a sleep-focused stack with apigenin, this is the optimal form.
Magnesium glycinate — good alternative: Glycinate has calming properties through the glycine amino acid component, which itself has sleep-supporting effects. It is well-absorbed and well-tolerated. If L-threonate is unavailable or too expensive, glycinate is the best substitute. Futuro Labs offers Magnesium Glycinate as part of its UK-manufactured range.
Magnesium citrate — acceptable but suboptimal: Better absorbed than oxide but primarily acts as a muscle relaxant and mild laxative. Less neural activity than L-threonate or glycinate.
Magnesium oxide — avoid for sleep: Poor absorption (approximately 4%). Primarily acts as a laxative. Not useful as a sleep supplement.
How to take them together
Timing: Take both 30-60 minutes before bed. Magnesium L-threonate has a slightly longer onset than apigenin, so some users take magnesium at the 60-minute mark and apigenin at 30 minutes. Taking both at 30-45 minutes works well for most people.
With food: Either supplement can be taken with or without food. A light evening snack is fine but not required.
Add L-theanine for the full stack: 200mg L-theanine completes the Huberman protocol — adding alpha wave promotion to the GABA calming and NMDA relaxation already provided by apigenin and magnesium.

Frequently asked questions
Can I take apigenin and magnesium together?
Yes — this is the recommended approach. They work through complementary mechanisms (GABA-A and NMDA respectively) with no known negative interactions. Take both 30-60 minutes before bed.
Which magnesium should I take with apigenin?
Magnesium L-threonate is the preferred form for sleep stacking — it is the only form clinically shown to cross the blood-brain barrier. Magnesium glycinate is a reasonable alternative with calming properties. Avoid magnesium oxide for sleep purposes.
What doses should I use?
50mg apigenin + 145mg elemental magnesium from L-threonate (approximately 2g of the compound). These are the amounts specified in the Huberman sleep protocol.
Is it safe to take both every night?
Yes. Both compounds are well-tolerated for daily use with no reported dependency, tolerance, or interaction effects. The combination addresses different sleep barriers simultaneously.
