Live weller, longer

Some therapies add years to your life. Other therapies add life to your years. Nutrition therapy does both.

Welcome to CEIO Nutrition—your wellest life beyond cancer, diabetes, and heart disease starts here.

Here at CEIO Nutrition

We help people facing cancer, diabetes, and heart disease move from feeling confused to clear, exhausted to energized, and chronically ill to chronically well—through personalized nutrition therapy that treats the whole person, not just their symptoms.

Because these conditions don’t happen in isolation.
Neither should your nutrition care.

Still dealing with brain fog, fatigue, or pain—even after treatment?

You’re not alone—and you don’t have to figure it out by yourself. At CEIO Nutrition, we help people navigating cancer, diabetes, and heart disease find clarity, energy, relief, and a personalized path forward. Because we know that a complete care plan goes beyond diagnosis codes and drug lists.

Whole-Person Nutrition Therapy—From Someone Who Gets It

Hi, I’m Janell Kaplan—founder of CEIO Nutrition, board-certified and state-licensed nutritionist, and an Institute for Functional Medicine–trained practitioner. I specialize in personalized nutrition therapy for people navigating cancer, diabetes, heart disease, and the chronic conditions that often come with them.

As a long-time cancer survivor living with autoimmunity, arrhythmia, and late effects from life-saving treatments, I know what it’s like to be told you’re “fine” when you’re still feeling anything but. That’s why I created CEIO Nutrition—to deliver care that’s clinically sound, deeply personalized, and rooted in empathy.

I serve clients across the District of Columbia, Maryland, Virginia, Florida, New Jersey, and beyond—offering a level of support I wish I’d had during my own recovery.

If you’re looking for real answers and a partner who sees the whole you, you’re in the right place. Read more about me.
