Function x Chase Sapphire: Spend Different

Spend different.

Today, most things we want can be ordered instantly. Food. Clothes. Devices.

We've become very good at spending on things, and far less intentional about spending on the thing upstream of everything else: our health.

Health shapes how much energy we have, how clearly we think, and how consistently we show up. It sits beneath every ambition, experience, and relationship. Yet it's often treated as something you react to, not something you actively support. In fact, Americans now spend nearly $15,000 annually on health, yet only 3.6% of that investment actually supports sustaining health over time.

That approach misses what matters most.

Health is an economic decision

Health spending is inevitable. The only variable is timing.

You either invest early—or pay later.

The cost of being unwell rarely arrives all at once. It accumulates through lost energy, missed work, and medical expenses that compound silently over time. Delaying attention to health costs more than supporting it early.

Time is a major part of that cost. Time waiting for answers. Time navigating appointments. Time feeling off without knowing why. It doesn't show up on a bill, but it's one of the most expensive parts of the system.

Changing where health lives

Function was built on a simple belief: small, early steps in health create meaningful returns.

Function offers people a more in-depth view of what's happening inside their bodies. One system. Together, not scattered. Across core systems—including heart health, hormones, metabolic health, immunity, and nutrition.

That information earlier expands what's possible. Decisions happen sooner. Risk gets addressed earlier. Fewer surprises. Fewer unnecessary interventions.

That's what it means to be on top of your health.

Why this matters

Most spending disappears the moment it's made. Spending on health compounds.

With better information, people make better decisions. With ownership, they act earlier. And when health is supported upstream, the downstream costs shrink.

Health is priceless. How we choose to spend on it is not.

Spend different. Choose health.

This is the most comprehensive lab testing I have ever had. I am thrilled to know more about my health and how to improve it.

Best money I have spent on healthcare.
