Uncovering Andrew Huberman's Supplement Recommendations: Boosting Concentration and Vitality
In the realm of cognitive enhancement, Andrew Huberman, a Professor of Neurobiology and Ophthalmology at Stanford University, offers a strategic supplement stack designed to optimise focus and brain performance. The stack includes Alpha GPC, L-Tyrosine, and caffeine, each serving a unique role in boosting mental acuity.
According to a study by Bunzeck et al. (2006), the human Substantia Nigra/VTA plays a crucial part in the absolute coding of stimulus novelty. This finding underscores the importance of maintaining optimal brain function, especially when it comes to attention and focus.
One key component of Huberman's stack is Alpha GPC, a choline source that supports the production of acetylcholine, a neurotransmitter closely tied to learning, attention, and memory. The recommended dosage for Alpha GPC is 300 to 600 mg per dose, taken 3 to 5 times per week before workouts or cognitively demanding tasks. This strategic, limited-frequency dosing is aimed at avoiding tolerance and overstimulation while maximising cognitive benefits.
L-Tyrosine, another supplement in Huberman's stack, is a precursor that the body uses to produce dopamine, a brain chemical involved in motivation, pleasure, and reward. L-Tyrosine supplementation can help with stress and anxiety reduction, as stated by Willis (2024), and it improves focus and attention, particularly under stress. However, due to its role in dopamine production, it is recommended to take L-Tyrosine no more than once per week to avoid tolerance.
Caffeine, a naturally occurring stimulant found in coffee, tea, and other plant-based sources, works by blocking adenosine, a compound that promotes relaxation, thereby encouraging wakefulness and sharper focus. When combined with L-Theanine, caffeine helps smooth out stimulation, promoting calm energy and focused concentration. The typical nootropic use of caffeine involves moderate doses (e.g., 100-200 mg) to optimise alertness without overstimulation.
L-Theanine, a naturally occurring amino acid originally found in green tea leaves, supports relaxation and balanced alertness by increasing GABA, known as the brain's calming neurotransmitter, and promoting alpha brain wave activity. This supplementation improves attention and decreases reaction times during mentally demanding tasks and further enhances learning and cognitive performance.
It is essential to note that while these supplements can aid in cognitive enhancement, they should be used strategically and in moderation. Huberman's approach emphasises limited-frequency dosing to avoid tolerance and overstimulation while maximising cognitive benefits.

In the realm of health-and-wellness, these supplements can aid in optimizing focus and brain performance, as advocated by Professor Andrew Huberman at Stanford University. The nutritional components of his stack include Alpha GPC, which supports learning, attention, and memory, and L-Tyrosine, which improves focus and attention, particularly under stress. When used strategically and in moderation, as per Huberman's approach, they can maximize cognitive benefits while avoiding tolerance and overstimulation.
