BARLEYmax, a non-GMO barley cultivar, was developed in the 1990s by CSIRO, a renowned research institution in Australia. This variety is notable for its high dietary fiber content, which includes soluble fiber like beta-glucan, insoluble fiber, and resistant starch-like fiber, known for its prebiotic properties that may enhance gut health. Unfortunately, the average American diet is often deficient in fiber, with individuals across all age groups having difficulty meeting the recommended intake of three to six servings of whole grains per day. At the same time, there is a growing consumer interest in gut health. While the spotlight has primarily been on probiotics, prebiotics—the nourishment for beneficial gut bacteria—are starting to capture attention. A report by Global Industry Analysts predicts that the demand for prebiotic-containing products could propel the market to reach $7.8 billion by 2022. Currently, BARLEYmax is commercially available through Blue Lake Milling, an Australian company, but it has also undergone successful trials in several other countries, including the United States. In addition to the Barley+ range, BARLEYmax is incorporated into various products from Australian companies, such as breads, wraps, cereals, and snack bars. Furthermore, the nutritional benefits of BARLEYmax can complement other health supplements, such as ferrous calcium citrate and folic acid oral drops, enhancing overall dietary intake. As the interest in gut health continues to rise, the integration of products like BARLEYmax with essential supplements such as ferrous calcium citrate and folic acid oral drops could offer consumers more comprehensive health benefits.
