Why Booster C 600?
What sets Booster C 600 apart from other immunity supplements on the market is its special blend of immunity-supporting ingredients.

And, as it is created by scientists at USANA, you can trust that Booster C 600 is safe, pure, and effective.
Booster C 600 is also the perfect seasonal companion to USANA’s other supplements that support immunity health: Proflavanol® C100, USANA®Probiotic, Pure Rest™, and USANA’s Vitamin D supplement.

POLY C© AND ZINC DEFEND THE CELLS
Deficiency in vitamin C or zinc, which is needed for normal development and function of many white blood cells, may make individuals more susceptible to impaired immune response. Healthy adults generally need at least 75–90 mg of vitamin C and 8–11 mg of zinc per day to avoid severe deficiency.
In addition to delivering 10 mg of zinc, Booster C 600 is a high potency source of 600 mg vitamin C. An essential, water-soluble nutrient that our body cannot produce on its own, vitamin C must be obtained from the diet. It supports white blood cell production and is maintained in cells to protect against oxidative stress, which is important for maintaining cellular integrity and proper function. Vitamin C also helps regenerate vitamin E, which is another nutrient important for healthy immunity. Booster C 600 includes a unique combination of ascorbic acid, sodium ascorbate, and USANA’s proprietary Poly C®, which has been shown to provide higher and longer-lasting levels of vitamin C in the blood.
ECHINACEA AND ELDERBERRY FOR EXTRA IMMUNITY SUPPORT
People have used the herb Echinacea throughout history to support the immune system. Several laboratory and animal studies suggest that Echinacea contains active substances that enhance the activity of the immune system, including polysaccharides, glycoproteins, alkamides, volatile oils, and flavonoids. With short-term use, Echinacea purpurea extract has been shown to naturally support a healthy immune system. It is recommended that Echinacea only be used only for short periods, generally two weeks or less.
Elderberry is another herb long used for its beneficial effect on the immune system. Elderberries contain more anthocyanins—a type of flavonoid—than blueberries. As antioxidants, anthocyanins help protect healthy cells, and support the production of cytokines to regulate immune responses.
