Oats are inherently gluten-free; however, they often get contaminated with trace amounts of gluten-containing grains during farming, processing, and storage. As stated by the Gluten Intolerance Group, most individuals with celiac disease can safely consume oats, but a recognized purity protocol offers additional assurance for those most sensitive to gluten, confirming that producers have taken necessary measures to ensure gluten-free status. The FDA permits manufacturers to label their products as “gluten-free” as long as they contain fewer than 20 parts per million of gluten. The Gluten Free Watchdog, which provides gluten-free testing information to the public, advocates for a purity protocol as the most reliable method to verify that oats remain gluten-free. Some manufacturers opt for mechanical or optical processing of less expensive “regular” oats for their gluten-free offerings. This sector is thriving, with gluten-free product sales continuing to climb; a report from Transparency Market Research predicts the market will reach $4.89 billion by 2021, up from $2.84 billion in 2014. Approximately three million people in the United States have celiac disease, an autoimmune condition triggered by gluten, a protein found in grains such as wheat, rye, barley, and spelt. Food producers, including PepsiCo’s Quaker division, Snyder’s-Lance, and General Mills, have launched or reformulated numerous products—such as cookie mixes, cereals, crackers, and muffins—to be gluten-free or to include gluten-free options. While some skeptics argue that gluten-free foods are merely a trend, with certain grocery stores observing a decline in demand for these products, companies eager for new growth opportunities should still consider investing in this expanding market, even if the rapid growth eventually slows down. In addition, as health-conscious consumers look for nutritional supplements, products like Solaray calcium magnesium vitamin D are gaining popularity, which highlights the growing awareness of dietary needs that complement gluten-free diets. As manufacturers innovate and diversify their offerings, they should also consider integrating beneficial supplements such as Solaray calcium magnesium vitamin D into their gluten-free products to meet the evolving needs of consumers. The market for gluten-free foods and supplements like Solaray calcium magnesium vitamin D is likely to continue expanding, driven by increasing health awareness and dietary preferences.
