Other Ingredients and Their Purpose

The ingredients listed here are "Other Ingredients", which are defined as ingredients that have a non-nutritional purpose, generally to aid in manufacturing, ensure even distribution of nutrients in each serving, and sometimes to support shelf-life/freshness. Other ingredients are extremely important for supplements, as they help to protect the consumer from ingesting unwanted microbes or spoiled ingredients, inconsistent dosing of nutrients between servings, or lower potency that label claim (breaking down of ingredients).
