Overview

Nutricost's spirulina supplement provides 3,000 mg per serving from CCOF-certified organic spirulina, packaged as 180 capsules for 30 servings. It's gluten-free and vegetarian.

At six capsules per serving to reach 3,000 mg, this is a higher daily capsule count than many single-capsule supplements, which is worth planning for if swallowing several capsules at once isn't comfortable. The CCOF organic certification is a specific, checkable claim rather than a generic organic label.
