About this study

In plain language

This study tests whether taking 3 grams of spirulina, a blue-green algae, each day for 8 weeks improves mood and clear thinking. It compares spirulina with a placebo, which has no active ingredient. The study is for healthy adults ages 18–65 from the ASU campus community.

Spirulina platensis is a form of cyanobacteria, a blue-green algae, and is a superfood most known for being rich in protein, vitamins and minerals, and healthful phytochemicals. Spirulina supports brain health through neuroprotection offered by its antioxidants, anti-inflammatory properties, and hormone regulation. The aim of this study is to supplement healthy adults from a campus community with 3g of spirulina, daily, for 8 weeks to improve mood and mental acuity in comparison to receiving a placebo.

Compensation is read from the study's own description and may be missing — always confirm with the study team.
