Why OncoCare Exists

Most supplements aren't formulated for chemotherapy

Hidden Interactions

Many common supplements interfere with ADC therapy through CYP3A4 pathway interactions.

No Oncology Standard

General wellness brands aren't designed for patients in active treatment. Dosing and timing aren't optimized.

Patients Left Guessing

68% of cancer patients take supplements without clinical guidance. Oncologists rarely have time to advise.

Interaction-Aware

Every ingredient passes what we call the Checkpoint Test , evaluated against your drug's CYP3A4 enzyme pathway before it enters any OncoCare formula. Your chemo works the way your oncologist designed it. Your supplements work without getting in the way.

Protocol-Specific

We formulate for ELAHERE and ENHERTU , not general wellness. Your drug. Your protocol.

Evidence-Based Dosing

Doses drawn from peer-reviewed ovarian and breast cancer clinical studies, not supplement convention.

Our Story

Born from a real patient's journey at MD Anderson

OncoCare didn't start in a lab or a boardroom. It started in a hospital waiting room at MD Anderson Cancer Center in Houston, Texas, where a husband was doing everything he could to help his wife through stage IV ovarian cancer.

Navigating supplement decisions in real time, cross-referencing clinical studies, checking CYP3A4 drug interactions, coordinating with the integrative medicine team, revealed a gap no one had filled: cancer patients in active treatment had no supplement brand built specifically for them. Most products on the market were designed for general wellness, not for someone on an ADC chemotherapy protocol.

So we built one. Every OncoCare formulation starts with the drug, not the supplement shelf. We ask: what does this patient's specific chemotherapy do, what does it deplete, what does it stress, and what does the peer-reviewed literature say can help without interfering? That question drives every ingredient decision we make.
