This document provides information on vitamins and supplements from a study conducted by the Literary Elegance Ladies Book Club in Sign Language. It includes brief descriptions of vitamins A, B1-B7, and B9, noting their uses and benefits. For each vitamin, 1-2 sentences summarize its function - for example, vitamin B1 is used to properly store carbohydrates and treat B1 deficiency, while B6 may improve mood and promote brain health. The document serves as a reference guide for the book club's 2019 project examining vitamins and supplements.
