Health Supporting Supplements for Cancer Care

Posted by Riordan Clinic Staff on Jan 21st 2021

Supplement regimens for all of our patients are carefully tailored to their individual needs. However, there are handful of supplements that we find many of our patients use during their cancer journey.

Vitamin C
Oral Vitamin C helps keep plasma levels optimal between infusions and provides ammunition for the immune system.

Vitamin D3
Vitamin D3 deficiency has been linked to most cancers and is associated with a worse prognosis. We find that most cancer patients are deficient in this critical nutrient. (1)

Coriolus is a medicinal mushroom with immune benefits. Studies show improved outcomes in several tumor types when combined with standard therapies. (4)

Melatonin is most often know for its sleep benefits, but it also helps with immune function, cell signaling, and hormone balance. (3)

Curcumin is mainly used as an anti-inflammatory, and has been shown to help with all hallmarks of cancer. It may also prevent drug resistance in cancer cells. (2)

This information is for educational purposes only, and we are not prescribing or recommending these products to all cancer patients. It is best to speak with a medical provider before starting a new supplement regimen.
