Glossary Vitamin Supplements

products providing essential vitamins not sufficiently obtained from diet

Vitamin supplements are products designed to provide essential vitamins that may not be consumed in sufficient quantities through diet alone. They come in various forms, including pills, tablets, capsules, drops, and injections, and are used to prevent or address deficiencies, support overall health, and sometimes manage specific health conditions. For instance, individuals with alopecia might use vitamin supplements like biotin or vitamin D to potentially improve hair health, although the efficacy can vary based on individual circumstances and underlying causes.
