IP-6 (Inositol hexaphosphate)

Tier 3 — weak evidence · Immunity · Cancer adjunct

A naturally occurring compound found in grains and legumes that may support immune function. Lab studies show it enhances natural killer cell activity, and small clinical trials suggest possible benefits as an adjunct alongside conventional cancer treatment. Human evidence is still limited and more research is needed. Generally well tolerated at standard doses.

Dose: 1–8 g/day in divided doses on an empty stomach; evidence mostly preclinical
