Our VeganCaps™ are made from tapioca, which is naturally fermented into a water-soluble polysaccharide known as pullulan. This material provides the best oxygen barrier properties of any vegetarian capsule and dissolves just as easily as a gelatin capsule and faster than traditional veggie caps. In addition, HealthForce SuperFoods® VeganCaps™ are starch free, preservative free, gluten-free, and GMO free. Our VeganCaps™ are also certified kosher. Unfortunately, most vegetarian capsules on the market are made from genetically modified corn. They also usually contain sodium lauryl sulfate (SLS), a synthesized surfactant used in many cleaning and personal care products as a binding agent in the capsules.
