Introducing...

Functional Cardiometabolic Optimization Program

Heart Health & Longevity, Redefined.

Lumen Connect is the only platform that links your real-time metabolic data directly with your physician and integrates your wearables for a complete daily metabolic picture — and it is offered exclusively through Dr. Cruz’s practice.

Discover what happens when you truly work with your metabolism — in real time.

Your metabolism is deeply connected to how your heart functions, how you feel day-to-day, and how your body responds to nutrition, stress, sleep, and movement.
This program helps you understand — and optimize — those connections using real-time data, clinical expertise, and personalized cardiometabolic care.

The Functional Cardiometabolic Optimization Program is a data-driven, high-touch approach designed to improve your energy, metabolic flexibility, body composition goals, and long-term cardiovascular health.

We combine:

  • Metabolic testing through Lumen Connect

  • Wearable insights — sleep, HRV, recovery, and activity from your Oura Ring, Apple Watch, or preferred device

  • Lifestyle patterns — nutrition, stress responses, movement habits

  • Clinical cardiology expertise

  • Monthly progress reviews to track trends and make targeted adjustments

This is a dynamic, evolving program built to identify the drivers of your cardiometabolic health and create a personalized plan that adapts as your data — and your body — change.
