Most practitioners never consider the eyes when evaluating metabolic health. But what if vision changes are an early sign of deeper dysfunction?

In this episode of ReInvent Healthcare, Dr. Ritamarie Loscalzo sits down with Dr. Rani Banik—a board-certified neuro-ophthalmologist and integrative medicine expert—to explore how eye health is influenced by diet, oxidative stress, and blood sugar imbalance.

This episode is a must-listen for practitioners who want to expand their root-cause lens and empower clients to protect their vision naturally.
