Natural Compounds in Dietary Supplements for Prostate Cancer

Share Button

I gave a live webinar this past week and openly talked about the use of supplements for prostate cancer without citing any of my recommendations. The following is a list of natural compounds I think should be considered for prostate cancer in supplementation.

By no means is this article suggesting to replace your doctor’s advice with dietary supplements.  This blog post is not meant to replace a clinical visit with an expert on prostate cancer, but rather to serve for educational purposes.

Seek expert advice.


May Prevent metastasis

Helps with prostate cancer by several mechanisms of action including reducing inflammation, antioxidant activity and potential apoptosis (natural cell death) activity


Works synergistically while with Docetaxel treatment for prostate cancer

Inhibits Vascular Endothelial Growth Factor (VEGF), meaning the ability for cancer cells to form their own blood vessels for survival.

Modified Citrus Pectin

Prevents metastasis by inhibiting a molecule called galectin – 3

Helps men with biochemical recurrence for prostate cancer


Reishi mushroom (Ganoderma lucidum)

Anti-cancer benefits from numerous mechanisms

Stimulates Natural Killer (NK) cells in the body, T-lymphocytes and other white blood cells – very important in keeping cancer cells at bay.


Grape Seed Extract

Stops prostate cancer progression

In a human study, there was a 41% reduction of prostate cancer


Vitamin E

SELECT trial showing INCREASE prostate cancer from alpha-tocopherol vitamin E

Without gamma tocopherol vitamin E, alpha-tocopherol can be a problem.

This study looking at over 10,000 men showed protection when gamma-tocopherol is combined with alpha-tocopherol. 

For an easy to read clarification on the different types of vitamin E  and my opinion on why mixed-tocopherol is important for prostate cancer read this.

    Just listened to your talk.My husband has aggressive prostate cancer. Excellent protocol, but you did not talk about what fruits, if any to eat.
    What fruits are in the CAPLESS Method?

    Dr. Geo –

    Have you read “How to Starve Cancer?”. If so, what do you think?

    • Dr. Geo 06/23/2019, 9:45 PM

      I have not. But I will. Thank you.

    I have started to eat roasted Pumpkin Seeds, and put Pumpkin Oil in my Smoothies,

    I enjoyed the talk also and the information related to supplements. I wonder what your comments are related to the possible inpact of the protein methionine on prostate cancer growth. I understand some believe that its restriction will slow cancer growth.
    Thank you.

      There have been numerous animal studies to suggest to reduce consumption of methionine and glutamine for prostate cancer and that may slow progression. I think it is a good a idea to reduce consumption, but eliminating it is impossible and can cause other health problems.

    Do these supplements help in suppressing breast cancer growth?

    • Dr. Geo 07/20/2019, 3:53 PM

      Very likely, though breast cancer is not my expertise. Many things that work for prostate cancer work for breast cancer as well.
