Introduction: Huberman's Approach to Supplements

Andrew Huberman, the renowned neuroscientist and professor at Stanford University, has gained a massive following with his podcast "Huberman Lab." He is known for translating complex scientific findings into practical, actionable protocols. A central pillar of his strategy for optimizing health and performance is the targeted use of dietary supplements.

Huberman does not select his supplements arbitrarily. His approach is strictly evidence-based: He relies on peer-reviewed studies, meta-analyses, and clinical data. For him, supplements are tools that can support specific physiological processes or compensate for deficiencies when nutrition and lifestyle alone (/en/tools/fuel-target) are insufficient. He repeatedly emphasizes that dietary supplements cannot replace a solid foundation of sleep, exercise (/en/research/periodization-the-architecture-for-maximum-hypertrophy), and nutrition but should only complement it.

His protocol is dynamic. It includes both daily and cyclic elements aimed at specific goals such as focus, sleep, hormone balance (/en/research/autophagy-maximum-cellular-cleanup-through-pro-fasting-hacks), or general health. He adjusts his stack based on current research findings and his own experiences. Let's dive in together and analyze his daily and cyclic stack in detail (/en/tools/supplement-interaction-checker) to understand what he takes, why, and what the science says about it.

Huberman's Morning Routine and Focus Supplements

For an optimal start to the day and maximum cognitive performance, Huberman relies on a combination of supplements that support neurotransmitter systems and promote alertness. He typically takes these after his morning caffeine delay (often 90-120 minutes after waking) to avoid disrupting the natural cortisol rise (/en/research/light-protocols-calibrate-your-scn-for-peak-performance).

Alpha-GPC

Alpha-GPC (Alpha-Glycerylphosphorylcholine) is a choline source that can efficiently cross the blood-brain barrier. In the brain, it is converted to choline, a precursor of the neurotransmitter acetylcholine. Acetylcholine plays a crucial role in learning processes, memory, attention, and muscle contraction.

Mechanism of Action: Increases acetylcholine levels in the brain, which can improve synaptic plasticity and neuronal communication. It can also stimulate the release of growth hormones.
Dosage: Huberman often recommends 300-600 mg, sometimes up to 1200 mg, before cognitively demanding tasks. He does not take it daily but as needed.
Evidence: Studies show that Alpha-GPC can improve cognitive function in healthy adults and patients with cognitive impairments Sagaro & Amenta, 2025 (https://doi.org/10.3389/fneur.2025.1649661) Parker et al., 2011 (https://pubmed.ncbi.nlm.nih.gov/21807119/). It is also used in the sports sector for performance enhancement.

L-Tyrosine

L-Tyrosine is an amino acid and a direct precursor of the catecholamines dopamine, norepinephrine, and adrenaline. These neurotransmitters are crucial for motivation, attention, mood, and the stress response (/en/research/hrv-measurement-guide).

Mechanism of Action: Under stress or sleep deprivation, catecholamine stores can be depleted. L-Tyrosine can help replenish these stores and thus maintain cognitive performance and mood.
Dosage: Huberman typically takes 500-1000 mg L-Tyrosine as needed, especially when under stress or requiring high mental performance.
Evidence: Research suggests that L-Tyrosine can improve cognitive performance, particularly working memory and flexibility, under acute stress conditions Deijen et al., 1999 (https://pubmed.ncbi.nlm.nih.gov/10230711/).

Caffeine Combined with L-Theanine

This combination is a classic for improved alertness and focus without the typical side effects of caffeine alone.

Caffeine: An adenosine receptor antagonist that blocks fatigue and promotes the release of neurotransmitters such as dopamine and norepinephrine.
L-Theanine: An amino acid primarily found in green tea. It can cross the blood-brain barrier and increase alpha-wave activity in the brain, promoting a state of relaxed alertness. L-Theanine can also mitigate the negative effects of caffeine (https://pubmed.ncbi.nlm.nih.gov/18006208/) such as nervousness and rapid heartbeat.
Optimal Ratio: Huberman often recommends a ratio of 1:2 or 1:1 of caffeine to L-Theanine, for example 100 mg caffeine with 200 mg L-Theanine. The exact dosage depends on individual tolerance.
Neurochemical Effects: The combination leads to a synergistic effect: Caffeine increases alertness, while L-Theanine improves concentration and at the same time exerts a calming effect that reduces the "jitter."
Evidence: Numerous studies confirm the synergistic effects of caffeine and L-Theanine on attention, reaction time, and the reduction of distractibility Payne et al., 2025 (https://doi.org/10.1093/nutrit/nuaf054) Owen et al., 2008 (https://pubmed.ncbi.nlm.nih.gov/18681988/).

Sleep and Recovery Supplements in His Stack

Sleep is the absolute foundation for health and performance for Huberman. He places great emphasis on optimizing sleep quality (/en/research/sleep-hrv-digital-twin) and uses specific supplements for this that can promote relaxation and improve sleep architecture (/en/research/deep-sleep-hack-how-to-trigger-genuine-cellular-regeneration).

Magnesium Threonate or Bisglycinate

Magnesium is an essential mineral involved in over 300 enzymatic reactions in the body, including processes important for sleep. Huberman prefers specific forms of magnesium due to their bioavailability (/en/research/magnesium-how-to-activate-real-atp-in-your-cells) and their ability to cross the blood-brain barrier.

Why These Forms?
Magnesium Threonate: This form was specifically developed to increase magnesium concentration in the brain (https://pubmed.ncbi.nlm.nih.gov/20152124/). It is assumed to improve synaptic density and plasticity, which can have a positive effect on memory and learning ability. For sleep, the effect on GABA receptors is relevant.
Magnesium Bisglycinate: Here magnesium is bound to the amino acid glycine. Glycine itself has calming properties and can lower core body temperature, which promotes sleep. This form is also very well tolerated and causes digestive problems less often than other magnesium forms.
Influence on GABA and Sleep Quality: Both forms can support the activity of the neurotransmitter GABA (gamma-aminobutyric acid). GABA is the most important inhibitory neurotransmitter in the brain and helps reduce neuronal excitation, leading to relaxation and sleep. For more on how magnesium activates real ATP in your cells, see our article Magnesium: How to Activate Real ATP in Your Cells (/de/research/magnesium-kinetik-bioverfuegbarkeit). A detailed breakdown of the different magnesium forms is provided in our article Magnesium Glycinate vs Threonate vs Citrate vs Malate: Which Form for Which Purpose? (/de/research/magnesium-glycinat-vs-threonat-vs-citrat-vs-malat).
Dosage: Huberman typically takes 140-200 mg elemental magnesium 30-60 minutes before bedtime.

Apigenin

Apigenin is a flavonoid found in chamomile and parsley. It is known for its mild calming and anxiolytic properties.

Mechanism of Action: Apigenin binds to GABA-A receptors in the brain, similar to benzodiazepines but with much lower affinity. This leads to a calming effect without the strong sedative effects or the dependency potential of prescription medications.
Study Situation: Research suggests that apigenin can improve sleep quality and reduce anxiety Shao et al., 2013 (https://pubmed.ncbi.nlm.nih.gov/23871424/). It is a gentle aid for sleep support.
Dosage: Huberman uses 50 mg apigenin before bedtime.

Myo-Inositol

Myo-Inositol is a sugar alcohol that acts as a secondary messenger in many cellular processes (/en/research/hack-hayflick-limit), including the signal transduction of neurotransmitters such as serotonin.

Effects on Serotonin and Sleep Architecture: Myo-Inositol plays a role in the sensitivity of serotonin receptors. Improved serotonin signaling can have a positive effect on mood and sleep regulation. There are indications that it can influence sleep architecture, particularly the duration of REM sleep.
Dosage: Huberman takes 900 mg myo-inositol before bedtime. He mentions that higher doses (up to 18 g) are used in clinical studies for other purposes, but a lower dose is sufficient for sleep.
Evidence: The evidence for myo-inositol specifically for sleep improvement is not yet as robust as for magnesium, but there are promising studies, particularly in the context of anxiety disorders and depression, which are often associated with sleep disorders Palatnik et al., 2001 (https://pubmed.ncbi.nlm.nih.gov/11386145/).
