Plenity is free of gluten, soy, wheat, peanuts, shellfish, lactose, dairy, sugar, alcohol, latex, and mercury. It also doesn't have any dyes, preservatives, or ingredients that are related to Para-Aminobenzoic Acid. Plenity is derived from natural sources: carboxymethyl cellulose (modified cellulose - cellulose is the fiber found in vegetables and plants) and citric acid (found in many fruits like lemons and limes).
