Combinations of Natural Products and Repurposed Drugs as Adjunct Cancer Therapy

Natural supplements can be very helpful adjuvants to drug therapies, for example, through chemosensitization of tumor cells. Unfortunately, it seems that very often there's little or no follow-through when readily available natural products show great potential in cancer treatment. However, rational combination therapies can significantly improve outcomes.  I’ve created a visual guide with arrows and symbols highlighting synergistic interactions, key pathways, and processes between various compounds. These represent some of the safest and most effective natural substances for inhibiting cancer growth and proliferation through multiple mechanisms.

    (OTC) medications: I've included a few non-oncology drugs that, if used in combination with specific supplements, could enhance their anti-cancer action. Repurposing non-oncology drugs is an attractive approach to improving cancer therapy.

    Enhancing Absorption and Bioavailability


    Consuming fat-soluble supplements alongside dietary fats like ghee butter or coconut oil can improve their absorption and utilization in the body. The ideal dosage for the compounds discussed in this blog is uncertain and would vary based on the type of cancer, the specific target, and the individual patient's response to the treatment.


    Timing: Optimizing Supplement Intake for Enhanced Efficacy

    It might be beneficial to take anticancer supplements late at night and to include a time during the night in your supplementation schedule, e.g., 3AM "study suggests that nighttime is the right time for cancer to grow and spread in the body and that administering certain treatments in time with the body's day-night cycle could boost their efficiency{ref|ref}

    Synergistic Combinations


    A natural substance may show potential against cancer. Still, its effectiveness is often limited by the need for excessively high concentrations to achieve significant benefits (in vitro concentrations not achievable in vivo). However, if synergies exist, those same substances may become significantly more effective at lower concentrations. Such combinations of nutraceuticals can also be used to overcome drug resistance or to sensitize cancer cells to therapeutic agents.

    Drug interactions


    Be aware of drug interactions, e.g., concurrent use of natural products with anticoagulants may result in prolonged bleeding times and should be avoided. 


    Safe and responsible use of natural supplements and repurposed medications


    Supplements should only be taken under the supervision of your healthcare provider or oncologist. Supplements or herbal preparations shouldn't be combined with chemotherapy, radiotherapy, immunotherapy, or any other cancer treatment unless the safety and efficacy of such combinations are established. It's vital to make sure anything you add to the standard treatment will further improve its effectiveness

    1. Moved Piperlongumine back to #1 since it's now available as a supplement and should be a good combination with Artemisinin because of overlapping anti-cancer mechanisms (CT,FER,ST3). A good spot right under curcumin.
