Can diabetic clients consume FRUSSO? Can. FRUSSO does not consist of sucrose or glucose, only a small amount of fructose, and fructose doesn't cause a spike of blood sugar, so using 1 or two sachets of FRUSSO on a daily basis would not affect the blood sugar of diabetic patients. https://www.onehealth.sg/2022/04/05/how-probiotics-affect-your-digestion/
