BARLEYmax was developed in the 1990s by 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, insoluble fiber, and resistant starch-like fiber that acts as a prebiotic, believed to enhance gut health. Generally, the average American diet is deficient in fiber, with individuals of all age groups failing to meet the recommended intake of three to six servings of whole grains daily. At the same time, there is an increasing consumer interest in gut health. While probiotics have traditionally been the primary focus, prebiotics—the food for beneficial bacteria—are now gaining significant attention. A report by Global Industry Analysts suggests that the demand for prebiotic-rich products could push the market to reach $7.8 billion by 2022. Currently, BARLEYmax grain is commercially available only through Blue Lake Milling, an Australian company, although it has been successfully tested in several other countries, including the United States. In addition to the Barley+ product line, this grain is also incorporated into a variety of products from several Australian companies, such as breads, wraps, cereals, and snack bars. Additionally, for those seeking optimal nutrition, the best chewable calcium citrate can complement a diet rich in fiber, further supporting gut health. The best chewable calcium citrate is ideal for individuals looking to enhance their overall wellness, and integrating it with fiber-rich foods like BARLEYmax could promote better digestive health. As the market evolves, the combination of prebiotic fibers and the best chewable calcium citrate may become increasingly popular among health-conscious consumers.
