Key Points

  • Before using this therapy, consult your oncology team about interactions with other treatments and therapies. Also make sure this therapy is safe for use with any other medical conditions you may have.
  • Zyflamend is a multicomponent supplement blend taken for inflammation support, for pain and soreness, and for joint function and flexibility.
  • BCCT is interested in Zyflamend’s uses in reducing the risk of or to treat prostate cancer, its symptoms or side effects of disease treatment.
  • Evidence from lab and animal studies indicate it reduces inflammation and levels of enzymes that produce estrogen. It can also cause cell death.
  • It may enhance the cell-killing effects of certain chemotherapy drugs.
  • It generally has mild side effects, including heartburn, but some individuals may be hypersensitive to one or more of the components.
  • Zyflamend should not be used by pregnant or lactating women or in newborn infants.
  • There are no randomized controlled human clinical trials on the efficacy of Zyflamend to treat cancer.

Zyflamend is a supplement blend of 10 herbs taken orally for several purposes:

Treating the Cancer

Working against cancer growth or spread, improving survival, or working with other treatments or therapies to improve their anticancer action

Cinical Evidence

No definitive clinical trials of Zyflamend have been published, but a few small trials show benefits:

  • In a small phase I clinical trial in 2009 of men with HGPIN (a pre-cancerous abnormality of the prostate gland), 780 mg of Zyflamend plus combinations of other dietary supplements were administered three times a day. After 18 months, the majority of patients (60 percent) had only benign tissue at biopsy, and 48 percent of subjects demonstrated a 25 to 50 percent decrease in PSA. The treatment was well tolerated with no serious side effects.2
  • A 2017 review of the impact of several dietary choices and Zyflamend found that Zyflamend showed promise in reducing prostate cancer progression.3
  • A phase 1 clinical tried showed reduced prostate-specific antigen (PSA), a marker of prostate cancer, in about half of patients.4
  • While a 2013 review found that conclusive evidence for the use of complementary medicine in prostate and bladder cancer is lacking—and use also carries risk—the authors considered the 2009 phase I trial described above to be “robust evidence” of “the potential role of Zyflamend as a therapeutic agent.”5

Optimizing Your Terrain

  • Zyflamend shows anti-inflammatory properties in prostate cancer.12
  • Reduced levels of enzymes that produce estrogen13


Zyflamend is readily available online and in some stores and pharmacies that sell nutritional supplements. No prescription is required.

New Chapter, the manufacturer of Zyflamend, makes three formulations:

The clinical trial related to prostate cancer used the Zyflamend Whole Body formulation.


A few potential minor side effects have been noted, but Zyflamend is generally well-tolerated. The manufacturers recommend taking Zyflamend with food to reduce the risk of heartburn.

People can be hypersensitive to any of the herbs in Zyflamend.

One or more of its herbal constituents may interact with other prescription drugs or other herbs. Check with your pharmacist for herb-drug interactions. Also, before using Zyflamend, consult with your physician. If you are already taking Zyflamend, notify your physician.

European barberry, a component of Zyflamend, should not be used by pregnant or lactating women or in newborn infants, as it can cause kernicterus; several fatalities have been associated with use in these populations.14
