What are Essentials? To maintain health, we need a diversity of vitamins, minerals, bioflavonoids, and other nutrients. Although we receive many of these nutrients from our diets, it's impractical and virtually impossible to obtain an optimal dose through diet alone. USANA understands the importance of providing the right ingredients - in the correct amounts, in the right balance, and in the correct forms - for all age groups. For this reason, USANA has created the Essentials to provide the most well-rounded supplementation possible - a must for everyone interested in true health.
