Summary

This study tests whether a nutritional supplement called 'Think Tank' can improve thinking and memory in middle-aged women after they experience stress. Forty healthy women aged 40-60 will take either the supplement or a placebo and then complete cognitive tests. The goal is to see if the supplement helps with focus, memory, and mental flexibility when under pressure.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Skoshify 'Think Tank' nutritional formulation (magnesium, creatine, L-tyrosine, L-theanine, citicoline, rhodiola rosea, phosphatidylserine)
What this could lead to
If it works, this could point toward a natural supplement that helps people stay sharp and focused during stressful situations.
What could go wrong
This is a small, early-stage trial with only 40 healthy women, so results may not apply to everyone. The effects are measured over a short time, and supplements often show limited benefits in larger studies.
