Sometimes our immune system simply needs a boost. Stress, traveling, and busy schedules can leave us feeling run down and less than our best. USANA’s Booster C 600 supplies a powerful blend of ingredients shown to support immune defenses in those times when we need to stay healthy. The delectable, lemon-berry flavored powder can be taken straight or mixed with water for an immune boost anytime, anywhere.

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.

Staying healthy is vital to performing at our best every day. Many immune health products contain vitamin C, but only Booster C 600 contains USANA’s proprietary Poly C vitamin C blend to deliver stronger, longer-acting antioxidant defense. Blended with a high-quality, effective form of Echinacea, plus zinc and elderberry, Booster C 600 provides a perfect, portable solution for giving our immune system a little added support when we need it.
Q: What’s the difference between MySmart™Shakes and Nutrimeal™?
A: MySmartShakes are the cleaner, simpler products a growing segment of the population are clamoring for. They don’t have any sugar and are packed with six grams of fat—mainly from coconut oil—to provide the beneficial balance of macronutrients to combat today’s carbohydrate-heavy diets. MySmartShakes also give you the ability to personalize your shake. You’ll have a variety of flavors and proteins to choose from, instead of being stuck with only a few options.

Q: What do the numbers on my shake bags mean?
A: Each part of the MySmartFoods line is numbered to guide you through the process. So making your perfectly personalized MySmartShake is as easy as 1, 2, 3.

1. Choose your protein base—plant, soy, or whey
2. Choose your USANA MySmart™ Flavor Optimizer—dark chocolate, cappuccino, peach mango, banana, orange cream, or stick with the mild vanilla flavor of the base
3. Add in a booster, like USANA MySmart™Shake Protein Plus

Q: Will USANA be adding more flavors in the future?
A: Yes. Over the next few years, we plan to roll out more flavors. Keep checking on The Hub for more exciting MySmartFoods products.

Q: How will these new products affect the RESET™ Kit?
A: We’re changing the RESET Kit to MySmart™Start, and it will feature the MySmartFoods line. This means you’ll experience more personalization with a program that will help you start living a healthier lifestyle.

Q: Are MySmartFoods low glycemic?
A: We can’t talk about MySmartFoods and the glycemic index, but they do have a low-glycemic impact on your body. Here’s why:

There simply isn’t enough sugar to determine a glycemic-index score experimentally. In other words, they are naturally low glycemic in the same way that nuts or fish are. They contain too few carbohydrates to be tested, and their influence on blood glucose would be insignificant. So, while we can’t measure the glycemic index, of course they will help support your low-glycemic diet.

Q What went into the development of these new products?
A: We recognized a desire among consumers for simple, pure products. They want ingredients they can pronounce and easily understand. That means cleaner labels and ingredients that are closer to nature. One thing I was taught was to simply look at the length of an ingredient deck—almost always, shorter is better.

This was also an opportunity to add in more beneficial fats—mainly from coconut oil—to provide a better balance of macronutrients: carbohydrates, protein, and fats. For a long time, the story was that fats were bad. When you dig into the scientific literature, that’s just not the case.

Q: So what’s going on with the saturated fat in the products? A: Fats are a vital nutrient, especially for our cells. And the type of fats found in coconut oil—which is what we use in these products—has quite a few health benefits. It’s been shown to support healthy metabolism, and contribute to satiety. There’s also evidence coconut oil supports healthy triglyceride levels and maintains good cholesterol levels already in the normal range.*

Q: How will the shakes and bars benefit my overall diet?
A: That’s a great question. We are very good at talking about “essential” micronutrients—the vitamins and minerals that are essential to sustain life. However, we often forget there are “essential” macronutrients as well. MySmartFoods offer both essential and beneficial macronutrients designed to help bring our overall diet back into balance.

Around the world, we are consuming more calories coming mostly from refined sugars, and more specifically, from snacking. The primary goal of these new products is to help restore balance in our diet, and combine them with the USANA® Essentials™ to provide the essential macro- and micro-nutrition our bodies need to thrive.

Q: Will the products make me feel full longer?
A: Besides fat, it is well known and scientifically documented that increased amounts of fiber and protein will also help increase the overall sense of satiety and boost your metabolism. Just two of the many health benefits these macronutrients provide.
