## Mechanism of Action

Seru Berry's anthocyanins inhibit the NF-κB [inflammatory pathway](/ingredients/condition/inflammation) while stimulating interleukin-2 production to enhance T-cell proliferation and [white blood cell](/ingredients/condition/immune-support) activity. The berry's ellagic acid activates AMPK (adenosine monophosphate-activated protein kinase), improving glucose uptake and insulin receptor sensitivity. Additionally, its proanthocyanidins enhance nitric oxide bioavailability, promoting vasodilation and [cardiovascular](/ingredients/condition/heart-health) protection.

## Clinical Summary

Limited human studies include a 12-week trial with 86 participants showing 23% improvement in fasting glucose levels with 500mg daily supplementation. A smaller pilot study (n=34) demonstrated 18% increase in natural killer cell activity after 8 weeks of use. Most research consists of in-vitro and animal studies showing promising [anti-inflammatory](/ingredients/condition/inflammation) and metabolic effects. More robust clinical trials are needed to confirm therapeutic efficacy in humans.
