The Brain's Energy Crisis
Your brain is an energy-hungry machine. Despite making up only a small fraction of your body weight, it consumes roughly 20% of your total energy. This energy is supplied by ATP (Adenosine Triphosphate).
When you are performing difficult mental tasks—like coding, mathematical calculation, or strategic planning—your neurons fire rapidly. This "neuronal depolarization" demands massive amounts of fuel to reset the ion gradients in your cells. If you can't supply energy fast enough, your brain performance drops. You experience this as "mental fatigue".
The Study: Creatine vs. Placebo
Creatine is famous for helping muscles recover between lifting sets. It turns out, it does the exact same thing for neurons.
In a double-blind, placebo-controlled, cross-over trial (the gold standard of research), researchers at the University of Sydney tested 45 young adults. The subjects were given 5g of creatine daily for six weeks.
The Results: Smarter and Faster
The results were not subtle. Supplementation had a "significant positive effect" (p<0.0001) on two major cognitive metrics:
1. Working Memory (Backward Digit Span)
This test measures how well you can hold information in your head and manipulate it. Subjects on creatine could remember significantly longer sequences of numbers than when they were on the placebo.
2. Fluid Intelligence (Raven’s Advanced Progressive Matrices)
This is a standard non-verbal IQ test that measures problem-solving speed and pattern recognition. Scores improved significantly after creatine supplementation, suggesting that increasing brain energy directly translates to better "computational power".
Who Needs It Most?
The study focused on vegetarians and vegans. Since creatine is naturally found in red meat, vegetarians have lower baseline levels of creatine in their tissues. However, even omnivores rarely get enough dietary creatine to fully saturate their brain's storage. Supplementation ensures your "backup battery" is fully charged.
The WellFact Protocol
Dosage: 5 grams of Creatine Monohydrate per day.
Timing: Any time of day (consistency is key).
Expectation: It takes a few weeks to saturate your brain tissues. Don't expect a miracle in 1 hour; expect a baseline improvement over 1 month.
