Calgee's 100% Plant-Based Omega-3 is derived from algae in a strict, controlled sustainable environment that is traceable from end to end. You’ll never have to worry about heavy metals, toxins, fillers, ocean-borne contaminants, or whether you’ve swallowed something questionable along with your capsule. Each nutrient-dense tapioca softgel (carrageenan free) contains pure algal oil, which offers a high bioavailability source of DHA & EPA.
