Thick-It instant food thickening products have revolutionized the way people think about food and dysphagia care since 1987. For more than 20 years, their goal has been to develop safe products that help improve the quality of life for those with dysphagia and their caregivers. Thick-It Original Instant Food Thickener was the first healthcare food thickener on the market introduced in 1987. In 2005, Thick-It Purees, a line of great-tasting and shelf-stable pureed foods, were introduced.
