We all want a sharper mind, and the supplement industry knows it. This week, David and Jessica dig into the science of cognitive enhancement and ask the uncomfortable question: Does any of it actually work? From nootropic stacks and brain-training apps to the bold claims plastered across every “smart pill” label, they break down what the research really says, and it’s not what the marketing wants you to believe.

But here’s the good news: the most powerful IQ-boosting tools aren’t in a capsule or an app. David and Jessica explore the evidence-backed, unglamorous habits that genuinely move the needle on cognitive performance, memory, and mental clarity, and why we keep ignoring them in favor of a quick fix.

If you’ve ever bought a brain supplement or paid for a cognitive training app, this episode is for you.
