Spirulina and diet combo shows promise for obese men
NCT ID NCT06076161
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.
