To keep focused and driven at work and to mitigate decision fatigue, there are several dietary supplements and nutrients that might help based on current research. Here are some ideas:

1. Caffeine: Widely recognized for its ability to enhance alertness and focus, caffeine also has potential benefits for improving vigilance and attention during long periods of wakefulness¹.
2. Creatine: Known primarily for its benefits in muscle performance, creatine has also been shown to have potential cognitive benefits, particularly in memory and mental fatigue².
3. B Vitamins: These vitamins (e.g., B6, B9, B12) are crucial for energy metabolism and neuronal function. Deficiencies in these vitamins can lead to cognitive impairments and increased mental fatigue³.
4. Omega-3 Fatty Acids: Found in fish oil, these fatty acids (mainly EPA and DHA) are essential for supporting brain health. They have been implicated in improved cognitive function, better memory, and mood regulation⁴.
5. L-Theanine: Often found in tea, L-theanine can work synergistically with caffeine to enhance focus and attention without causing the jitters⁵.
6. Ginkgo Biloba: This herbal supplement is thought to enhance cognitive functions and protect against cognitive decline by improving blood flow to the brain⁶.
7. Rhodiola Rosea: An adaptogen that can help to combat fatigue and improve mental performance and concentration⁷.
8. Probiotics: The gut-brain axis plays a significant role in cognitive function, and improving gut health with probiotics can have positive cognitive effects⁸.

These supplements might be beneficial for maintaining cognitive function and mitigating decision fatigue:

• Bacopa Monnieri: An herbal supplement with potential benefits for memory and cognitive function, often used in traditional medicine⁹.
• Ashwagandha: An adaptogen that helps the body manage stress, which can indirectly improve cognitive functions and reduce fatigue¹⁰.
• Phosphatidylserine: A phospholipid that is crucial for maintaining cellular function in the brain and has been shown to improve cognitive function and mood¹¹.
