All FTF formulations, including Hormone Synergy and Metabolic Synergy, are completely sugar-free. We sweeten our powder blends naturally using Stevia leaf extract, which contains zero calories. Hormone Synergy also includes zero-glycaemic Erythritol. Because these clean sweeteners pass through the digestive system without converting into glucose, they will not spike insulin levels, disrupt a fasting state, or trigger mid-afternoon sugar cravings.
