BARLEYmax was developed in the 1990s by the CSIRO, a renowned research institution in Australia. This non-GMO barley cultivar is recognized for its high content of dietary fiber, which includes both soluble fiber, such as beta-glucan, and insoluble fiber, along with resistant starch-like fiber that offers prebiotic benefits believed to enhance gut health. Generally, fiber intake is insufficient in the typical American diet, with individuals across all age groups having difficulty achieving even one serving of the recommended three to six servings of whole grains daily. As consumer interest in gut health continues to grow, the focus has primarily been on probiotics, but there is increasing attention on prebiotics—the food that nourishes beneficial bacteria. According to a report by Global Industry Analysts, the demand for prebiotic-rich products could propel the market to an estimated value of $7.8 billion by 2022.
Currently, BARLEYmax grain is commercially available through an Australian company, Blue Lake Milling, and has also been successfully trialed in various countries, including the United States. In addition to the Barley+ product line, this grain is incorporated into numerous offerings from other Australian companies, such as breads, wraps, cereals, and snack bars. For consumers interested in optimizing their health, understanding how to take calcium citrate alongside fiber-rich foods like BARLEYmax can also contribute to better nutritional outcomes. As awareness grows, there may be more exploration into how to take calcium citrate effectively, complementing the benefits of prebiotics in promoting overall well-being.
