Alaska Blueberry (Vaccinium uliginosum or closely related species) is recognized for its high content of antioxidants, particularly anthocyanins, flavonoids, and vitamin C. These compounds have been shown in numerous laboratory and animal studies to neutralize free radicals, thereby reducing oxidative stress and potential cellular damage. The antioxidant properties of blueberries in general are well-documented, with several in vitro and in vivo studies indicating their ability to scavenge reactive oxygen species and protect biomolecules from oxidative injury.

While most studies have focused on common blueberry species (Vaccinium corymbosum), Alaska Blueberries are similarly rich in bioactive compounds. Some research specifically examining wild, northern blueberries—including those from Alaska—has found them to possess particularly high antioxidant capacity compared to cultivated varieties. Human clinical trials on blueberry consumption have demonstrated improvements in biomarkers of oxidative stress, but these studies rarely isolate Alaska Blueberry as the exclusive species.

In conclusion, the use of Alaska Blueberry for supporting or treating free radical damage is scientifically plausible and supported by moderate-quality evidence, mainly extrapolated from broader blueberry research. However, direct large-scale human trials using specifically Alaska Blueberry are limited, which tempers the strength of the evidence from a 4 or 5 down to a 3.
