Supplements for Men With Prostate Cancer
When it comes to dietary supplements, less is more. Mega-doses suggest a worse outcome or prognosis in patients with cancer.
Vitamins
B12 may be needed if blood tests show a deficiency. Excess B vitamins may promote heart disease and cancer growth. Researchers have not found that Vitamin C helps prevent or treat prostate cancer. For Vitamin D, I generally recommend 1,000 IU daily if the level is below normal. Men with prostate cancer should not take an individual Vitamin E supplement. Higher doses of Multivitamin pills may feed prostate tumors. Taking a children’s multivitamin several times a week, not to exceed one pill a day, makes more sense. Folic acid and Zinc in higher amounts have been associated with a higher risk of aggressive prostate cancer in human studies.
Fish Oil (Omega-3 fatty acids)
Pills containing EPA and DHA may reduce the risk of cardiovascular events and may have anti-arthritic and anti-depressive properties. Some new research suggests it could encourage the growth of some prostate cancers.
Ginger
500-1,000 mg per day may reduce nausea during and after chemotherapy. Korean Red Ginseng, MAC A, L-arginine, L-citrulline, and American Ginseng show in preliminary data to improve sexual health. Panax ginseng may help reduce fatigue in cancer patients. American ginseng from the Ginseng Board of Wisconsin is arguably the safest, least expensive, and most effective option for fatigue.

Glucosamine, Pycnogenol, SAM-e, Lycopene and Resveratrol
Show no evidence of anti-prostate cancer activity. The few studies published to date are inconclusive and controversial.
Quercetin
It has been used with some success in chronic nonbacterial prostatitis.
Saw Palmetto & Other BPH Supplements
In two major clinical trials, the most commonly used dosage was safe but did not work better than a placebo.
Selenium
Supplements may increase the risk of aggressive prostate cancer!
Tea and Tea Supplements
Most forms of tea, including black, green, herbal, and oolong are healthy and have few or no calories, so enjoy drinking them. However, please keep in mind that tea-based dietary supplements or pills (not the drink) have no solid proof from human studies that they do anything against prostate cancer. A large clinical trial of high-dose green tea supplements in patients with advanced cancer showed no real benefit.
Whey Protein or Protein Powder
Have been shown to be ineffective at building muscle.
Zinc
Zinc supplements in high dosages, 80 to 100 mg per day or more, should be avoided. Recent human research has linked higher doses of zinc from dietary supplements to abnormal immune changes, a potential reduction in the impact of bone-building drugs, abnormal changes in cholesterol blood tests, increased risk of urinary tract infections, kidney stones, prostate enlargement, and an increased risk of aggressive prostate cancer.
Conclusion
Always talk to your doctor about any pill or supplement. Use the same approach to taking a dietary supplement as you would use for starting a prescription medication.
