Andrew Huberman Supplements list for focus: Stanford Neuroscientist recommends

Published Jun 2, 2023 | Updated Feb 8, 2024

Andrew Huberman is a Professor of Neurobiology & Ophthalmology at Stanford University. He started his podcast, the Huberman Lab Podcast in 2021 where he talks about the brain and neuroscience. It is currently one of the top 15 podcasts worldwide. He has over 1 million followers on social media and is a credential source in a sea of non-evidence-based influencers. With a PhD in neuroscience and over 20 years of experience in the field, Dr Huberman knows what he is talking about. 

What supplements does Andrew Huberman recommend?

His nootropic (cognitive enhancer) stack compromises Alpha GPC, L-tyrosine, and caffeine. This is the science behind Andrew Huberman supplements list and how they enhance brain health:

Alpha GPC

Your learning, attention and memory brain chemical is acetylcholine. The memory area in your brain is rich in acetylcholine-producing cells[1]. This brain chemical is also directly involved in attention tasks, by prioritising brain activity in active areas and eliminating distractions to help you focus. To make adequate acetylcholine, you must ensure a good supply of its building block, choline. It is found in protein-rich foods like beef liver, eggs, and almonds. So, what does Andrew Huberman recommend for memory? One of the most efficient supplemental forms of choline, Alpha GPC. Alpha GPC can easily enter the brain and has one of the highest choline contents in supplements. (41% of choline by weight). brain feed has created the world’s 1st 500 mg Alpha GPC capsule containing 99% Alpha GPC* (the purest form of Alpha GPC). It works quickly by increasing acetylcholine levels within 1-3 hours after intake[2].

How much Alpha-GPC does Andrew Huberman take? 

He mentioned a 300-600 mg intake of Alpha GPC to enhance learning[3].  A 29-year-long review of different studies found that 1200mg alpha GPC improved memory scores in over 400 people[4]. Those supplementing also saw an increase in attention scores[5].

Your reward and pleasure brain chemical is called dopamine. Feel-good activities like good food, sex, exercise, and thrill-seeking bring an influx of dopamine. What does Andrew Huberman say about dopamine? Dopamine is deeply involved in motivation and drive. Those with high levels of self-motivation were found to have higher dopamine release in the reward and motivation brain areas[6]. According to Huberman, dopamine loves novelty, with brain scan studies showing increased release when subjected to new experiences[7]. You can incorporate its role in reward and motivation to try and excel at new skills. The building block of dopamine is L-tyrosine, found in protein-rich foods such as cheese, tofu, and beef. You can also find supplemental forms of L tyrosine. Huberman takes L-tyrosine to increase dopamine levels. Upon intake, L-tyrosine levels peak after 1-2 hours and remain in the blood for up to 8 hours[8]. Dr Huberman recommends a 500-1000 mg intake of L-tyrosine to enhance dopamine production[5]. brain feed has created the world’s 1st natural 800mg tyrosine capsule from fermented corn.



Caffeine, the stimulant commonly found in tea and coffee, is another tool in Dr Huberman’s toolkit. After intake, caffeine levels peak within 30-60 mins[20], which helps explain why you feel alert soon after your first cup of coffee in the morning. Caffeine works by blocking a brain chemical that promotes sleep (adenosine)[20]. A shot of espresso provides an average of 60 mg of caffeine[21]. 150mg of caffeine can enhance alertness on cognitive performance for 10 hours[22]. A balance is needed because, at high doses of 500-600 mg, caffeine can increase heart rate and shivers[20]. As opposed to improvements in memory functions, caffeine performs simpler enhancements like improved reaction time and alertness[23]. This is particularly useful in situations of mental fatigue. Military individuals and long-distance drivers who were required to stay focused for long periods had better vigilance after 200 mg doses of caffeine[23]. Though it helps to wake you up, excess caffeine intake can make you jittery and must be stayed clear of, as per Andrew Huberman. Sleep-deprived individuals have also seen benefits on 100-300mg, which can limit the errors performed on attention tasks.


Featured in Andrew Huberman sleep cocktail compared to his cognitive enhancer stack theanine, is another supplement Huberman claims to use. L-theanine is a natural compound first found in the tea plant[9,10]. Constituting 1-2% of the dry weight of green tea, l-theanine is also found in small amounts in some food sources and supplemental forms[11]. L-theanine helps you relax while still keeping you alert by increasing your relaxation chemical GABA as well as brain waves linked to focus known as alpha waves[12,13,14,15,16]. A study on 18 healthy university students showed that l-theanine supplementation resulted in improved attention and faster reaction times[17]. The researchers also recorded an enhanced activity of the alpha brain waves which enhance your ability to absorb new information and boost your creative thinking[18]. Discover how l-theanine and caffeine for caffeine jitters are a good combo[19]. brain feed’s l-theanine is extracted from green tea. It is kept as pure as possible to ensure science-based results.

Dr Huberman’s focus formula 

Andrew Huberman recommended supplements when performing intense work, involving a combination of those 3 supplements. Andrew Huberman routine is taking the following to maximise his alertness and concentration: Alpha GPC + tyrosine + caffeine. This winning combination contains nutrients that improve focus, and increase motivation, reaction times and alertness to maximise productivity. 

What supplement brand does Andrew Huberman use? 

Andrew recommends several different supplement brands on his podcast with the common denominator being brands with a focus on potency, purity and efficacy. brain feed has the world's 1st 99% Alpha GPC 500mg capsules and the world's 1st 800mg tyrosine from fermented corn ticking all 3 of the above criteria.
