Summary

This study looked at whether taking spirulina supplements along with cutting calories can help obese men lose weight, lower cholesterol, and improve how their body uses insulin. Thirty-five men took either spirulina or a placebo for 30 days while following a reduced-calorie diet. The goal was to see if the combination leads to better body measurements, blood fats, and markers of oxidative stress.
