If you love dark chocolate, our new ZoneRx 2 bar is for you. With a rich dark chocolate flavor, mild sweetness, and the consistency of a brownie this will soon become a household favorite. Each bar has the Zone balance you expect with 15 grams of protein and low glycemic carbohydrates. ZoneRx 2 bars now contain the natural low-calorie sweetener allulose giving each bar only 2 grams of total sugar. Couple this with 15 grams of prebiotics to support gut health and metabolism (AMPK activation) and there is no better way to feel your best. When it comes to hunger control we think it is one of our most satisfying bars yet, but you be the judge!

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. With high levels of polyphenols and prebiotics (fermentable fiber) each ZoneRx Bar helps support the release of satiety hormones while promoting gut health.

Unlike, typical bars you find in health food stores, these ZoneRx bars are true chocolate bars rich in cocoa polyphenols with low levels of heavy metals found in expensive dark chocolate bars and are Non-GMO.  That is only possible because we use CacaoRx, our proprietary reduced cocoa extract as our key ingredient in each ZoneRx bar.

What makes each ZoneRx Bar unique?
  • MaquiRx and CacaoRx — Our proprietary polyphenol extracts provide 350 milligrams of polyphenols to help activate genes that help reduce oxidative stress, inflammation and the rate of aging.
  • 15 grams of Protein — Balanced with low-glycemic carbohydrates, our bars help support stable blood sugar control.
  • 15 grams of Prebiotics — Fortified with prebiotics to help stimulate the growth of good bacteria in our gut. This helps with improved appetite control and gut health support.
  • Less Sugar — newly reformulated to contain allulose, a natural low-calorie sweetener that helps support better blood sugar control compared to fructose. ZoneRx bars now contain only 2 grams of total sugar!

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®.

Are ZoneRx 2 Bars Gluten Free?

Yes. We have verified from our vendor that the ingredient profile in the ZoneRx bar is gluten free. We have not gone through the certification process to place it on our current label. Please note these are made in a facility that processes wheat.

What Allergens does the bar contain?

Milk, Soy and Tree Nuts (Almond). The bar is made in a facility that processes peanuts, tree nuts, soy, dairy, eggs, wheat and fish gelatin.

Are the ZoneRx Bars Lactose Free?

No. There is lactose that comes from the milk fat and milk protein isolate.

Are the bars Non-GMO?


What are the sources of prebiotics?

Prebiotics are defined as nutrients that improve gut health. There are 15 grams of prebiotics in the ZoneRx 2 bars. The sources come from fermentable fibers (Tapioca Fiber, Chicory Fiber) and Allulose. Allulose has been shown to help improve microbial diversity in the gut.

How many polyphenols come from maqui vs. cocoa?

Each ZoneRx 2 bars contain 350 mg of total polyphenols. The amounts of maqui and cocoa are proprietary.

Does the cocoa in the ZoneRx 2 bar contain caffeine?

The cocoa used in ZoneRx 2 bars is highly purified to remove heavy metals such as cadmium while retaining polyphenol content. There is some residual caffeine and theobromine in the ZoneRx 2 bars.

Are ZoneRx Bars suitable for children?

ZoneRx 2 bars are the ideal snack for children as they are balanced in protein and carbohydrate, plus they contain prebiotics and polyphenols that promote the formation of good bacteria in our gut. There is no upper limit for polyphenol and the small amounts of caffeine should pose no risk for children.

Do ZoneRx Bars 2 contain artificial sweeteners?

No, the bars contain no artificial flavors or sweeteners.

Why are stevia and allulose used in over other sweeteners?

Stevia and allulose are natural based sweeteners versus artificial sweeteners. Stevia is a sugar substitute made from the leaves of the stevia plant and is about 100 to 300 times sweeter than table sugar. It contains no carbohydrates. Allulose is a natural sweetener that supports better blood sugar control compared to fructose. The combination of these two sweeteners is what allows the bars to be low in added sugar with only 2 grams of total sugar.

The bars state they use Controlled Release Nutrition. What does that mean?

Controlled Release Nutrition is the precise combination of protein, low-glycemic carbohydrate, and fat that helps to stabilize insulin levels to maintain peak mental alertness while also controlling satiety.

    whoever designed these new bars absolutely knocked it out of the park! i’ve had every version of the bars starting way back to the ones that (i think) were sold to zoneperfect. these are by far the most satisfying and delicious yet. highly recommended.

  2. Amirah Dahdul (verified owner)

    Greatest bars I’ve ever tasted! I love the allulose, makes this a perfect addition for anyone following a Keto/zone diet. I think I might need two boxes a month!! Thank you for adding a safe better sweet alternative!

    • Dr. Sears Zone

      Amirah, Glad to hear you love the ZoneRx 2 Bars!

  3. Annette Elliot (verified owner)

    My husband and I really enjoyed the old bars, but do not care for the new ones at all, and will not buy again. Be aware that these bars are very sweet tasting. It’s a pity, because we will miss the nutritional benefits we appreciated with the old bars.

    • Dr. Sears Zone Customer Support

      Annette, Thank you for your comment on the ZoneRx 2 Bars. The sweet taste you reference is related to the new low glycemic, all natural sugar called allulose that Dr. Sears utilizes in the bars. Taste is a very personal thing and we are sorry to hear the sweetness is not to your liking. The Zone Bars have gone through a number of changes over the years as the science evolves and new ingredients become available such as the allulose.

    Delicious, like a dark chocolate covered brownie with healthy ingredients! Check out stats on bar-impressive. This is the best health bar I’ve had with no chemical aftertaste and only 2 grams net of carbohydrates. Great polyphenols, prebiotics and protein. AMAZING!

  5. Philip Pelc (verified owner)

    Do not like the new bars as well as the old ones. I absolutely loved the old ones, and these are just okay. I guess that is what happens when you make them more nutritious. I will continue to purchase.

  6. Charmaine Mire (verified owner)

    These bars are definitely the most delicious meal replacement bars I have ever tried, and I’ve tried many. The chocolate has a lot of depth of flavor, very rich, and the chewy texture is very much like a brownie. They don’t hold me for 5 hours but they are a good balanced snack food.

  7. Scott Fabyanic

    The new bars are delicious, taste like a cross between a chocolate and fudge bar. The construct of nutritional constituents and the purity is quite impressive. Another great product by the Zone team. Keep up the excellent work. The only thing I could selfishly ask for is more flavors.
