Overview

A capsule antioxidant supplement delivering 6 mg of AstaREAL branded astaxanthin per serving, packaged by Nature's Lab as a 60 capsule bottle framed as a two month supply.

The listing names AstaREAL specifically as the astaxanthin source rather than a generic supplier, which is the main distinguishing detail on an otherwise single-ingredient product. It's gluten free per the spec.
