Can You Take Vitamins While on Semaglutide?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Yes, you can generally take most vitamins while using semaglutide for weight loss. Medical evidence shows that combining vitamins with GLP-1 medications like semaglutide is typically safe and often beneficial. Since semaglutide reduces appetite and food intake, you may consume fewer nutrient-rich foods, making vitamin supplementation important to prevent deficiencies in B12, vitamin D, iron, and folate. Water-soluble vitamins (B-complex, vitamin C) are particularly safe, while fat-soluble vitamins (A, D, E, K) should be monitored more carefully. Always consult your healthcare provider to develop a personalized vitamin plan that complements your semaglutide treatment.
