BARLEYmax was developed in the 1990s by CSIRO, a renowned research institution in Australia. This non-GMO barley variety was selected for its exceptional dietary fiber content, which encompasses soluble fiber like beta-glucan, insoluble fiber, and resistant starch-like fiber known for its prebiotic properties that are believed to enhance gut health. The average American diet is notably deficient in fiber, with individuals across all age groups often failing to meet the recommended intake of three to six servings of whole grains daily. Concurrently, there is a growing consumer interest in gut health. While probiotics remain the primary focus, prebiotics—the nutrients that nourish beneficial bacteria—are starting to receive more attention. A report by Global Industry Analysts suggests that the demand for prebiotic-rich products could propel the market to $7.8 billion by 2022. Currently, BARLEYmax grain is commercially available exclusively through an Australian company, Blue Lake Milling, but it has also been successfully tested in several other countries, including the United States. In addition to the Barley+ product line, the grain is incorporated into various products from Australian companies, such as breads, wraps, cereals, and snack bars. Furthermore, in the context of gut health and dietary supplements, products like Nutricost TUDCA 250mg are gaining popularity, as consumers seek additional support for their digestive well-being alongside fiber-rich options like BARLEYmax. As awareness of the importance of gut health continues to rise, both BARLEYmax and Nutricost TUDCA 250mg may play significant roles in helping individuals achieve their dietary goals.
