Gamma Tocotrienol, a member of the Vitamin E family, has been investigated for its potential to mitigate radiation-induced damage, particularly in preclinical settings. Several animal studies have demonstrated that gamma tocotrienol can protect against radiation-induced lethality and hematopoietic injury. The proposed mechanisms include antioxidant activity, modulation of cytokine production, enhancement of DNA repair, and stimulation of hematopoietic growth factors such as G-CSF. Notably, a number of these studies have been conducted by the Armed Forces Radiobiology Research Institute (AFRRI) and other institutions, indicating a concerted scientific interest.

However, there is currently no established clinical evidence in humans to support the use of gamma tocotrienol for the treatment or prevention of radiation sickness. The available evidence is limited to in vitro experiments and animal models (mostly mice and non-human primates). No randomized controlled trials in humans have been published as of 2024, and gamma tocotrienol is not approved by regulatory agencies for this indication.

In summary, while scientific research justifies further investigation, especially given the promising preclinical results, the direct evidence in humans is lacking. The use of gamma tocotrienol for radiation sickness is therefore supported by preclinical scientific evidence only, and not by tradition or clinical study.
