Rating (out of 5): 2

Spirulina has been investigated for its potential to support individuals exposed to radiation, particularly due to its antioxidant properties and its historical use in certain radiation-exposed populations. Some scientific studies, mostly in vitro, animal models, and limited small-scale human trials, suggest that spirulina may help mitigate radiation-induced damage. This potential is attributed to its content of phycocyanin (a pigment-protein complex), beta-carotene, and other antioxidants, which could theoretically help neutralize free radicals generated by ionizing radiation.

The most notable human studies come from research conducted in the aftermath of the Chernobyl nuclear disaster, where spirulina supplements were given to children exposed to radiation. Some small, uncontrolled studies reported improvement in bone marrow suppression and increased white blood cell counts. However, these studies had significant methodological limitations, including lack of control groups, randomization, and blinding, making the results difficult to generalize.

Systematic reviews and larger, well-designed clinical trials are lacking. Major health authorities do not currently endorse spirulina as a treatment for radiation sickness. While its antioxidant effects are promising in theory and some early studies are intriguing, the scientific evidence is preliminary and insufficient to support its routine use for radiation sickness in clinical practice.

In summary, spirulina's use for radiation sickness is supported by limited scientific evidence, but more rigorous research is needed to confirm its efficacy and safety for this specific condition.
