Description

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 RestTM, 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.
