Magnesium
Mineral
Impact
Highest effect
Typical dose:200–400 mg / day
Magnesium is a cofactor in hundreds of enzymatic reactions vital for brain health. It regulates neurotransmitters like glutamate and GABA, supports learning and memory, and helps manage the body's stress response, all of which are crucial for sustained productivity.
Omega-3
Fatty Acid
Impact
Highest effect
Typical dose:1000–3000 mg / day
Omega-3 fatty acids, particularly DHA, are a primary structural component of brain cells and neuronal membranes. Adequate levels are critical for neurotransmitter function, reducing neuroinflammation, and supporting memory and learning. EPA contributes to these effects and also supports mood.
Vitamin B12
Vitamin
Impact
Highest effect
Vitamin B12 is essential for converting food into usable energy (ATP) and for the synthesis of neurotransmitters. A deficiency, which is common, can directly lead to mental fog, poor concentration, and fatigue, making adequate levels foundational for productivity.

Vitamin B6
Vitamin
Impact
Highest effect
Vitamin B6 (as P-5-P) is crucial for the conversion of precursors into dopamine, norepinephrine, and serotonin. Adequate levels are essential for maintaining the neurotransmitter balance required for mental alertness, drive, and a positive mood.
Zinc
Mineral
Impact
Highest effect
Zinc is highly concentrated in the brain and plays a vital role in synaptic plasticity and communication between neurons. It also acts as an antioxidant. Deficiency can impair learning, memory, and mood, making adequate levels a key component of optimal cognitive function.
High effect
Acetyl L-Carnitine
Other
Impact
High effect
Acetyl L-Carnitine (ALCAR) crosses the blood-brain barrier to assist in mitochondrial energy production and provides acetyl groups for synthesizing acetylcholine, a neurotransmitter critical for focus, memory, and cognitive speed. It's particularly effective at reducing mental fatigue.

Alpha-GPC
Other
Impact
High effect
Typical dose:300–1200 mg / day
Acetylcholine is essential for learning, memory recall, and concentration. Alpha-GPC efficiently delivers choline to the brain, providing the raw material needed to produce this key neurotransmitter, thereby supporting overall cognitive horsepower and mental clarity.
Caffeine
Other
Impact
High effect
Typical dose:100–300 mg / day
Caffeine acts as an adenosine receptor antagonist, blocking the signals that induce drowsiness. This leads to increased neuronal firing and the release of excitatory neurotransmitters like dopamine and norepinephrine, resulting in a tangible boost in focus and wakefulness.
Cordyceps
Botanical
Impact
High effect
Cordyceps mushroom is known to improve the body's production of ATP, the primary energy molecule. This enhancement in cellular energy and improved oxygen efficiency directly combats mental fatigue, supporting sustained cognitive effort and endurance during demanding work.

Eleuthero
Botanical
Impact
High effect
Also known as Siberian Ginseng, Eleuthero enhances stamina and mental performance during stressful periods. It helps modulate the body's stress response, thereby preserving cognitive resources and allowing for sustained focus and productivity without being overly stimulating.

Huperzine
Other
Impact
High effect
Typical dose:50–400 mcg / day
Huperzine A is a powerful acetylcholinesterase inhibitor, which increases levels of the neurotransmitter acetylcholine, crucial for learning and concentration. Due to its long half-life and potency, it is best used cyclically (e.g., a few days on, a few days off) for specific demanding tasks or projects rather than for daily, continuous supplementation.
Rhodiola
Botanical
Impact
High effect
Typical dose:200–600 mg / day
Rhodiola rosea helps the body adapt to physical and mental stress by influencing key brain chemicals like serotonin and dopamine, and by moderating the stress hormone cortisol. This action helps preserve cognitive resources, leading to improved endurance and concentration during long or stressful tasks.
Theanine
Amino Acid
Impact
High effect
Typical dose:100–400 mg / day
L-Theanine is an amino acid that can cross the blood-brain barrier and increase alpha brain wave activity, which is associated with a state of 'relaxed wakefulness'. It can modulate neurotransmitters like GABA and dopamine, improving focus and attention without sedation.
Vinpocetine
Other
Impact
High effect
Vinpocetine enhances cerebral metabolism and circulation, delivering more oxygen and glucose to neurons. This action can improve memory, alertness, and processing speed, making it effective for periods of intense mental work.
