Supplements: Supporting Health and Cancer Research

Overview of Supplements

Supplements like milk thistle, black seed oil, and others have gained attention for their potential to support overall health and possibly aid in cancer management. While primarily studied in preclinical settings (cell lines and animal models), these compounds may complement conventional treatments by targeting inflammation, oxidative stress, and tumor growth pathways. Below, we explore their benefits, typical dosages, and proposed anti-cancer mechanisms, organized by synergistic pairings with light pastel color-coding and labels for clarity. Note that human clinical evidence is limited, and these should not replace medical treatments without professional guidance.

Support Against Herxheimer Reactions

The Herxheimer reaction (herxing) occurs when dying pathogens or cancer cells release toxins faster than the body can eliminate them, often during detox or antimicrobial therapies. Symptoms include fatigue, inflammation, and flu-like effects. Several supplements may help mitigate these reactions by supporting detoxification, reducing inflammation, or stabilizing the body’s response:
