In the pharmaceutical sector, it is utilized in formulations aimed at managing gastrointestinal disorders and boosting immune function. Additionally, stachyose is incorporated into dietary supplements and health products to support overall wellness. Its ability to act as a low-calorie sweetener also makes it a suitable alternative in sugar-free and diabetic-friendly food products.
