BARLEYmax was developed in the 1990s by CSIRO, a renowned research institution in Australia. This non-GMO barley variety is recognized for its exceptional dietary fiber content, which includes soluble fiber in the form of beta-glucan, insoluble fiber, and resistant starch-like fiber, all of which are believed to enhance gut health due to their prebiotic effects. The average American diet tends to be low in fiber, with people of all ages often failing to meet the recommended intake of three to six servings of whole grains each day. At the same time, there is a growing consumer interest in gut health. While the focus has primarily been on probiotics, prebiotics—the nutrients that feed beneficial bacteria—are increasingly capturing attention. A report by Global Industry Analysts suggests that the market for prebiotic products could reach $7.8 billion by 2022. Currently, BARLEYmax is commercially available only through Blue Lake Milling, an Australian company, but it has been successfully tested in several other countries, including the United States. In addition to the Barley+ product line, this grain is incorporated into various other offerings from Australian companies, such as breads, wraps, cereals, and snack bars. Furthermore, BARLEYmax can be paired with supplements like calcium citrate 900mg, enhancing its nutritional profile and supporting overall health. In summary, the potential of BARLEYmax, along with its compatibility with products like calcium citrate 900mg, highlights its role in promoting digestive wellness and addressing the fiber gap in modern diets.
