The Evidence-Based Guide to NAD+ for Peak Mental and Physical Performance

Three years ago, I was grinding 14-hour days building my company when I hit a wall that felt different from typical burnout. My morning focus sessions — once razor-sharp — turned into mental quicksand. By 2 PM, I'd need two espressos just to read emails coherently.

That's when a friend mentioned something that sounded like science fiction: "Your cellular batteries are dying, and there's actually a way to recharge them."

To my surprise, he was talking about NAD+ — and it turns out he wasn't wrong. What I discovered next led me down a rabbit hole of research that completely changed how I think about performance optimization. More importantly, it gave me back the energy and mental clarity I thought I'd lost to age and stress.

If you've been chasing performance through endless productivity hacks while ignoring what's happening at the cellular level, you're optimizing the wrong variables.

Here's what the science actually says about NAD+ and why it might be the missing piece in your performance stack.
