It’s important to give your immune system the support it needs, especially with the stress it’s under during winter. That’s why USANA created a new product specifically designed to support healthy immune defenses—Booster C 600™.
The proprietary Poly C used in the Booster C 600 blend has been shown to provide higher levels of vitamin C over a longer period of time.

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. Not only does it contain zinc, echinacea, and elderberry, but it also includes USANA’s own proprietary vitamin C supplement Poly C. 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. Because of the potent immune boosting ingredients that Booster C 600 provides, it should NOT be taken longer than two weeks at a time. It is the perfect solution just for those times when you feel your immunity needs a little boost.


Booster C 600™
Immune-support supplement

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.

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.
