Metabolic syndrome is a group of risk factors that can include raised blood pressure, altered blood glucose, abnormal blood lipids and excess waist circumference. Diagnosis and treatment require professional medical care.
Human trials and reviews have explored spirulina supplements in relation to some cardiometabolic markers. Results suggest possible small changes in measures such as blood lipids, glucose control or body weight, but findings vary by dose, product and population. Reviews also report substantial differences between studies and call for better trials.

Spirulina is a food and is not a treatment for metabolic syndrome.
