Spirulina lowered HOMA‑IR by 0.68 in a meta‑analysis — but the dose that produced this effect wasn't specified.
This is the first indexed meta‑analysis on spirulina for insulin sensitivity, so while the drop in HOMA‑IR is promising, we can't yet say how much to take or who benefits most.
HOMA‑IR is a score that reflects how well your body's cells respond to insulin — lower numbers mean less resistance. The analysis found that spirulina supplementation was linked to a modest but statistically significant improvement, but the included studies didn't specify a consistent dose, and the overall body of evidence on this specific use is still small.
Where this fits in the evidence
This is among the first studies we've indexed on Spirulina for Improved Insulin Sensitivity — treat it as an early signal until more research accumulates.
