Higher intracellular glutathione levels mean greater antioxidant protection, enhanced immune function, and more effective detoxification

General approach: If on Semaglutide 0.5 mg or less: Start tirzepatide at 2.5 mg If on Semaglutide 1.0 mg: Start tirzepatide at 5 mg If on Semaglutide 1.7-2.4 mg: Start tirzepatide at 5-7.5 mg Some providers start everyone at 2.5 mg regardless of previous dose to minimize side effects
