A study conducted by the Institute of Atomic Bomb Radiology at Hiroshima University, investigated the radiation-protective potential of NKG Kefir powder using a mouse model exposed to whole-body X-ray irradiation.

Study Design
Mice were divided into several groups and given different diets:

• • -Control diet only

• • -Milk powder (freeze-dried)

• -NKG Kefir powder

Following this, the mice were subjected to whole-body X-ray exposure, a standard method to study radiation-induced damage, particularly in the intestinal lining.

Key Observation
The intestinal crypts, which are responsible for regenerating the intestinal lining and are highly sensitive to radiation, were significantly better preserved in the group that received NKG Kefir powder:

• • -The regeneration rate of intestinal crypts was markedly higher than in the control group and the milk powder group.

• -The difference was statistically significant, suggesting a measurable protective effect.

Conclusion
These findings suggest that NKG Kefir powder may have radioprotective properties, helping to reduce intestinal damage caused by X-ray irradiation. This positions it as a potential functional food for radiation protection, especially in contexts involving medical imaging, cancer therapy, or occupational exposure.

This study adds a unique dimension to the health benefits of NKG Kefir, beyond probiotics and immunity, highlighting its potential to support cellular resilience under extreme biological stress.
