Cancer treatment is focused on fighting cancer. Your body needs support, too.

Chemotherapy, radiation, immunotherapy and other cancer treatments can place enormous demands on the body. While these treatments are designed to target cancer, they can also affect healthy tissues—including the digestive system.

Diarrhea, constipation, nausea, vomiting, appetite and nutrition problems, and fatigue can interfere with everyday life. The National Cancer Institute recognises these as common treatment-related concerns. [1]

Your quality of life matters

More than 80% of people with cancer experience fatigue during chemotherapy or radiation therapy. [2] Diarrhea can lead to dehydration and loss of nutrients, while nausea and vomiting can interfere with eating, hydration and maintaining weight. [3] [4]

These challenges can affect how you eat, sleep, work, participate in family life—and how you feel from one day to the next.

The gut is part of the cancer-treatment conversation

Your intestinal microbiome is a complex community of microorganisms that interacts with digestion, metabolism and the immune system.

A 2025 systematic review of 22 human studies found associations between gut microbiota and chemotherapy response, efficacy and treatment-related toxicity. More research is needed to establish causality. [5] Other reviews explore the microbiome’s role in treatment response and immune function. [6] [7]

Why microbiome support matters

Our microbiome-support program is designed to provide a structured approach to supporting intestinal microbial balance during this demanding period. It is intended to be used alongside—not instead of—your medical care.

A program, not just a probiotic

Cancer treatment is not a one-size-fits-all experience. Our program provides a deliberate regimen with attention to:

• Supporting the intestinal microbiome
• Maintaining digestive health
• Supporting nutritional well-being
• Providing a structured approach during treatment
• Continuing support beyond active treatment

You are treating more than a diagnosis

You are trying to maintain your strength, eat, sleep, keep your normal life going and be there for the people you love. Your microbiome is part of that picture.

Ask your healthcare professional whether microbiome support is appropriate for you.

Important

This program is intended to provide nutritional and microbiome support. It is not intended to diagnose, treat, cure or prevent cancer or any other disease, and it is not a substitute for medical treatment. Discuss supplements and microbiome-support strategies with your oncology team, particularly during active cancer treatment.
