Frequently asked questions
What is the healthiest sweetener?
Based on safety data and clinical research, allulose is the healthiest low calorie sweetener. It has a 30+ year safety record, activates GLP-1 for appetite control, and has zero glycemic impact.
Is allulose healthier than stevia?
Both are safe and natural, but allulose offers additional metabolic benefits: GLP-1 activation, potential glucose tolerance improvement, and prebiotic-like gut health benefits that stevia does not provide.
What sweetener do doctors recommend?
Many doctors and dietitians now recommend allulose for its natural origin, zero glycemic impact, clinical evidence for GLP-1 activation, and excellent safety profile.
Is erythritol unhealthy?
A 2023 Cleveland Clinic study linked erythritol to increased cardiovascular risk including heart attack, stroke, and blood clotting. Many health-conscious consumers are switching to allulose.
What is the safest artificial sweetener?
Allulose is not artificial — it is a natural rare sugar. Among all low calorie sweeteners, allulose has the cleanest safety profile with 30+ years of human consumption data and no health concerns.
