BARLEYmax was developed in the 1990s by the CSIRO, a renowned research institution in Australia. This non-GMO barley variety is recognized for its high dietary fiber content, which includes soluble fiber such as beta-glucan, water-soluble resistant starch-like fiber, and other forms that are believed to have prebiotic effects beneficial for gut health. The average American diet is typically low in fiber, with people of all ages struggling to meet the recommended intake of three to six servings of whole grains each day. At the same time, there is a growing interest in gut health. While the primary focus has been on probiotics, prebiotics—the food that nourishes beneficial bacteria—are starting to gain traction. According to a Global Industry Analysts report, the demand for prebiotic-rich products could propel the market to reach $7.8 billion by 2022. Currently, BARLEYmax is commercially available only through an Australian company, Blue Lake Milling, although it has been successfully trialed in several other countries, including the United States. In addition to the Barley+ product line, BARLEYmax is also incorporated into various products from other Australian companies, such as breads, wraps, cereals, and snack bars. Furthermore, enhancing gut health can be complemented with calcium citrate plus vitamin D, which is essential for overall well-being. As the market evolves, the integration of BARLEYmax and supplements like calcium citrate plus vitamin D could provide consumers with comprehensive health benefits, making it an exciting area for future growth.
