Our NEW ZoneRx Bars are the ideal snack to help stabilize blood sugar for at least three hours so that you maintain peak mental alertness with a corresponding lack of hunger.  Why?  Because of the high levels of polyphenols and prebiotics (fermentable fiber) in each ZoneRx Bar help support the release of satiety hormones as well as support optimal gut health.

Our new and improved crispy chocolate bars represent the first significant breakthrough in nutrition bars in the 21st century.  Unlike, typical bars you find in health food stores, these ZoneRx bars are true chocolate bars rich in cocoa polyphenols without the heavy metals found in expensive dark chocolate bars.  That is only possible because we use CacaoRx, our proprietary cadmium-free cocoa extract as our key ingredient in each ZoneRx bar.

Because they are superior to high-end chocolates in performance, we protect them during the summer months by sending them in insulated packages surrounded by ice packs to preserve their extraordinary taste and performance.  We will ship the ZoneRx bars during the summer months only on Monday through Wednesday to ensure they will arrive in the best possible condition to your destination.  For any destination greater than 2-day standard delivery, we will send them via 2-Day Air at no additional cost.  This is our commitment to the excellent customer service you would expect from Zone Labs.

What makes each ZoneRx Bar unique?
  • MaquiRx® and CacaoRx™ — Our proprietary polyphenol extracts provide 375 milligrams of polyphenols to help activate genes that help reduce oxidative stress, inflammation and the rate of aging.
  • 16 grams of protein — Balanced with low-glycemic carbohydrates, our bars help support stable blood sugar control.
  • Fortified with prebiotics — Enjoy improved appetite control and gut health support.

Our unique Controlled Release Nutrition technology allows the polyphenols and fermentable fibers to interact in the ZoneRx bar in optimal synergy for improved gut health. Your end result is three hours of appetite suppression with great taste.

If you want optimal gut wellness, you need a lifetime strategy and products that deliver results you can see, feel and test.  The ZoneRx bars are part of that dietary strategy. We call it Evidence-based Wellness®.

Zone bar technology has advanced…

ZoneRx represents the next generation of nutrition bar technology.  Dr. Sears introduced the first high-protein nutrition bar in 1992 that was balanced with low glycemic carbohydrates to stabilize blood sugars levels. Today, his new generation of ZoneRx bars is the first to also deliver high-dose polyphenols optimized for gut health.

How ZoneRx Bars work…

Each ZoneRx bar contains 375 mg of a combination of refined low-cadmium chocolate polyphenols plus MaquiRx. Together, these ingredients are needed to promote gut health and anti-inflammatory actions.  In addition, these levels of polyphenols coupled with the blood sugar stabilization resulting from the protein-to-glycemic load in the bar significantly increases satiety.  No other bar in the world today can come close to these levels of polyphenols that are required for both optimal gut health and maximizing satiety.

    This bar is delicious and gives satiety. However, I’m concerned about the soy it contains. Soy is not ideal for many, especially those with thyroid issues. In general I thought soy was less desirable than whey or other protein sources, so why soy in these bars?

    I am very unhappy with the new zone bar. You had a GREAT product and now you have a bar that is no different than any other bar on a store shelf. These new bars are loaded with soy and do not have the healthy effect that the original bars have. You have lost me as a customer.

    I absolutely love these bars! They should be sold in all the supermarkets. They’re better than anything at the candy isle, better than Snickers!

    You shipped Fedx to a PO box. And Fedx delivered to wrong street address.

    good taste, holds hunger for hours, melts in warm weather so be careful when you eat them.

    Like everything ! Taste,appetite control.
    Wish you could ship the orders in a way that protects the chocolate coating , it flakes in the heat.

    They’re MUCH closer to the original Zone bar (that now has nothing to do with Dr. Sears) and they seem to do the job.They don’t do well in the heat at all, so sitting in my mailbox. in Florida, all day until I get home is a problem. But as long as I don’t handle the bars and just put them in the fridge for a day, I don’t lose too much of the chocolate coating to the inside of the wrapper. However, it flakes off when you open the package and eat it. Be careful, the flakes go flying and you’ll have chocolate spots on your clothes and surroundings. Must be eaten with care. Still better than the junk at the grocery store (and three times the price.)
