💡 the neuroscientist states: “Start with the sleep stack first — it is the highest leverage intervention. Everything else depends on sleep quality.”
I want to be clear: I’m not sponsored by any supplement company. I take these based on the peer-reviewed literature. I’ve been doing this protocol for years and the data supports it.”

Frequently Asked Questions

How much does the the neuroscientist supplement stack cost per month?
The core stack (creatine, omega-3, D3/K2, magnesium, apigenin, L-theanine) costs approximately £35-50/month. Add AG1 and it rises to £110-120/month. Budget version without AG1 is entirely achievable and covers 90% of the protocol’s benefits.
Is the neuroscientist sponsored by supplement companies?
AG1 (Athletic Greens) is a a popular neuroscience podcast sponsor, and he discloses this. He has stated multiple times he took AG1 before the sponsorship. Creatine, magnesium, omega-3, and the sleep stack are not sponsored — these are personal protocol items he’s discussed independently in non-sponsored episodes.
Should I take everything the neuroscientist takes?
Start with the high-evidence base: creatine, omega-3, vitamin D3, and the sleep stack. These have 100+ studies each. AG1 can replace a multivitamin but is expensive. Alpha-GPC and Tongkat Ali are optional enhancements. Never start more than 1-2 new supplements per week so you can track effects.

a Stanford neuroscientist’s Supplement Stack: The Full Science-Backed Breakdown

Dr. a Stanford neuroscientist, Stanford neuroscientist and host of the a popular neuroscience podcast podcast, has been unusually transparent about his personal supplement protocol. Here’s a breakdown of his reported stack with the supporting evidence for each item.

Daily Foundational Supplements (the neuroscientist)

  • AG1 (Athletic Greens) — comprehensive greens powder. the neuroscientist’s main sponsor, so bias should be acknowledged. Evidence: greens powders provide micronutrients but aren’t superior to a varied diet.
  • Vitamin D3 (5000 IU) + K2 — strong evidence for immune function, bone health, and mood. the neuroscientist recommends testing first.
  • Omega-3 EPA+DHA (2–3g) — robust cardiovascular and anti-inflammatory evidence.
  • Magnesium threonate (300mg) + magnesium bisglycinate — for sleep quality and cognitive function. Threonate specifically crosses the blood-brain barrier.

Sleep Stack

  • Magnesium threonate (300mg) — cognitive and sleep quality
  • Apigenin (50mg) — chamomile extract, mild anxiolytic and sleep-promoting. Binds GABA receptors.
  • L-theanine (100–400mg) — promotes relaxation without sedation
  • Inositol (900mg) — some evidence for anxiety reduction and sleep onset improvement

Focus Stack (Morning)

  • Alpha-GPC (300mg) — enhances acetylcholine for focus and cognition
  • L-tyrosine (500mg) — dopamine precursor; useful for focus under stress

Evidence Caveats

the neuroscientist’s recommendations are generally well-grounded in mechanism, but not all have equivalent clinical evidence. Magnesium, omega-3, and vitamin D have the strongest human trial data. Alpha-GPC and apigenin have promising but more limited human evidence. Always individualize based on your specific health goals and consult a healthcare provider for medical conditions.

a Stanford neuroscientist, Stanford neuroscientist and host of the a popular neuroscience podcast podcast, has published his personal supplement stack in detail across multiple episodes. While he consistently notes that behaviors (sleep, exercise, light exposure) are primary, his supplement protocol has become one of the most referenced in the longevity and performance community.

Morning Protocol

  • AG1 (Athletic Greens) — Foundational greens powder with probiotics, vitamins, adaptogens. the neuroscientist takes this on waking before eating. (Note: the neuroscientist is a paid partner, which should be factored in when evaluating the recommendation.)
  • Vitamin D3 5000IU + K2 100mcg — With first meal. D3 for immune, mood, and testosterone support; K2 to direct calcium to bones rather than arteries.
  • Omega-3 EPA 1-2g + DHA 1g — With breakfast. the neuroscientist emphasizes EPA specifically for mood and cognitive function.
  • NMN 500mg + Resveratrol 1g — Taken together in the morning; the combination is intended to synergistically boost NAD+ pathways.

Pre-Workout

  • Alpha-GPC 300mg — Choline source for acetylcholine production; taken 30-60 min before exercise for cognitive focus and neuromuscular efficiency
  • Tyrosine 500mg — Dopamine precursor; the neuroscientist cycles this and doesn’t use it every workout to maintain sensitivity
  • Caffeine 100-200mg — He delays caffeine 90-120 minutes after waking to avoid the afternoon cortisol crash

Evening / Sleep Protocol

  • Magnesium threonate 145mg + Magnesium bisglycinate 200mg — Two forms combined for both brain penetration (threonate) and systemic relaxation (bisglycinate)
  • Apigenin 50mg — Chamomile extract that activates GABA-A receptors for mild sedation without tolerance buildup
  • L-Theanine 100-400mg — Promotes alpha-wave brain activity and reduces sleep latency; the neuroscientist notes it vivifies dreams for some people

What to Prioritize if Buying Only Some

The most universally applicable components from the neuroscientist’s stack (accounting for cost and evidence): Omega-3, Vitamin D3/K2, Magnesium glycinate. These three deliver the highest return per dollar and apply to almost everyone. The NMN/Resveratrol and sleep stack are valuable additions once the foundation is covered.
