BARLEYmax was developed in the 1990s by CSIRO, a renowned research institution in Australia. This non-GMO barley variety was recognized for its exceptional dietary fiber content, which includes soluble fiber like beta-glucan, insoluble fiber, and resistant starch-like fiber that exhibits prebiotic effects believed to enhance gut health. The typical American diet is deficient in fiber, as individuals of all ages often find it challenging to consume even one serving of the recommended three to six servings of whole grains each day. As consumer interest in gut health continues to grow, the emphasis has largely been on probiotics; however, prebiotics—the nourishment for beneficial bacteria—are increasingly capturing attention. A report by Global Industry Analysts suggests that the demand for prebiotic-rich products could propel the market to an impressive $7.8 billion by 2022. Currently, BARLEYmax is commercially available through Blue Lake Milling, an Australian company, but it has also been successfully tested in various other countries, including the United States. In addition to the Barley+ range, this grain is incorporated into a variety of products from several Australian companies, such as breads, wraps, cereals, and snack bars. Furthermore, incorporating BARLEYmax with calcium citrate 600 and vitamin D 400 can significantly enhance the nutritional profile of these products, reinforcing the importance of fiber and micronutrients in a balanced diet.
