What is Vitamin B1 (Thiamine)?
Vitamin B1, also known as thiamine, is an essential water-soluble vitamin that plays a crucial role in energy metabolism and brain function [1]. As a key player in the conversion of nutrients into energy, thiamine is vital for maintaining optimal cognitive performance and overall brain health [2].
Thiamine is a B-complex vitamin that was the first B vitamin to be discovered, hence its designation as B1. It's an essential nutrient, meaning our bodies cannot produce it, and we must obtain it through diet or supplementation [4].
Thiamine plays several crucial roles in the body and brain:
- Acts as a coenzyme in the metabolism of carbohydrates and branched-chain amino acids
- Essential for the production of neurotransmitters, including acetylcholine and gamma-aminobutyric acid (GABA)
- Supports the maintenance of myelin sheaths around nerves
- Contributes to the production of nucleic acids, which are necessary for gene expression
- Plays a role in antioxidant defense mechanisms in the brain [5].
The Science Behind Vitamin B1 (Thiamine)
Scientific research has revealed several potential benefits of Vitamin B1 supplementation for cognitive function and overall brain health:
- Cognitive Function: Studies suggest that thiamine is crucial for maintaining cognitive function. A review published in Nutrients found that thiamine deficiency can lead to significant cognitive impairments, while supplementation can improve cognitive performance [6].
- Brain Energy Metabolism: Thiamine plays a vital role in glucose metabolism, which is essential for brain energy. Research in the Journal of Alzheimer's Disease showed that optimizing thiamine levels could improve brain glucose metabolism and potentially slow cognitive decline [7].
- Neuroprotection: Thiamine has shown neuroprotective properties in various studies. A review in Molecular Nutrition & Food Research highlighted thiamine's role in protecting against oxidative stress and neuroinflammation [8].
- Mood Regulation: Some research suggests that thiamine may play a role in mood regulation. A study in Psychopharmacology found that thiamine supplementation improved mood and reduced fatigue in healthy young adults [9].
- Neuroplasticity: Thiamine is essential for the synthesis of acetylcholine, a neurotransmitter crucial for learning and memory. Research in Neurochemistry International suggests that adequate thiamine levels support neuroplasticity [10].
While these findings are promising, it's important to note that many studies focus on correcting thiamine deficiency. More research is needed to fully understand the cognitive benefits of thiamine supplementation in healthy individuals.
Benefits of Vitamin B1 (Thiamine)
Vitamin B1 (Thiamine) offers a wide range of potential benefits, primarily for cognitive function and overall brain health:

- Mood Support: Some studies suggest thiamine may have mood-enhancing properties [29]. This dual cognitive and mood-enhancing potential sets thiamine apart from many other nutrients.
- Neurotransmitter Support: Thiamine is essential for the synthesis of several neurotransmitters, including acetylcholine [30]. By supporting neurotransmitter production, thiamine may indirectly enhance various cognitive functions.
- Neuroplasticity: Adequate thiamine levels may support the brain's ability to form new neural connections [31]. This could have implications for learning, memory, and overall cognitive flexibility.
- General Brain Health: As an essential nutrient, thiamine supports overall brain health and function [32]. This foundational support for brain health is crucial for long-term cognitive wellbeing.
Remember, while these benefits are promising, individual experiences may vary. Consistent intake of adequate thiamine is typically necessary to experience its full range of effects.
Dosage and Usage
The Recommended Dietary Allowance (RDA) for thiamine is 1.2mg per day for adult men and 1.1mg for adult women. However, higher doses have been used in studies showing cognitive benefits. For example, a study published in Psychopharmacology used 50mg of thiamine daily and found improvements in mood and cognitive function [15].
For general cognitive support, a typical daily dose can range from 50-100mg of Vitamin B1 (Thiamine). This dosage aligns with doses shown to be effective in cognitive studies, while still being well within safe limits for long-term use.
Our Approach to Dosing
We select exact milligram dosages based on scientific studies associated with the specific ingredient. These dosages align the "minimum viable dose" to see positive associated benefits based on the research.
These MVD also will be higher than other competitors, but importantly lower than the specific studies references for one key reason. This reason is that many scientific studies look at short term data and results, as such they focus on higher end dosages to speed up the associated benefits (or negative side effects) of a specific ingredient. This is perfect for clinical scientific studies, but for everyday use, dosages should be reduced as we're looking for a longer term focus and approach on "focusing for decades not minutes". As a result, each individual ingredient has the minimum effective dosage, without overdoing any one specific ingredient when taken daily for an extended period of time.
When considering Vitamin B1 supplementation, it's crucial to understand its pharmacokinetics:
● Thiamine has a relatively long half-life in the body, estimated to be between 9 to 18 days [24].
● The body doesn't store large amounts of thiamine, and regular intake is necessary to maintain optimal levels.
● The effects of thiamine on cognitive function are ongoing as long as adequate levels are maintained in the body [25].
For optimal results:
- Daily intake is recommended to maintain consistent levels of Vitamin B1 in the body.
- Effects are not acute but rather cumulative over time with consistent use.
- Long-term, consistent intake is necessary for sustained cognitive benefits.
What to Look for in a Vitamin B1 (Thiamine) Supplement
When choosing a Vitamin B1 supplement, consider the following factors:
