Is Biotin (Vitamin B7) Safe with Semaglutide, Liraglutide (Ozempic, Wegovy)?

Consider supplementing with 2.5–5 mg/day of biotin if experiencing hair thinning or loss (telogen effluvium) associated with rapid weight loss. Biotin supplementation is generally safe; however, note that high-dose biotin can interfere with thyroid and troponin laboratory assays. Inform your provider before lab testing.
Why this interaction occurs
Telogen effluvium — temporary hair shedding — is a well-documented physiological response to rapid weight loss and caloric restriction, as seen with GLP-1 agonist therapy. While frank biotin deficiency is rare, reduced dietary variety and protein intake on GLP-1 therapy may contribute to suboptimal biotin status. Biotin plays a key role in keratin infrastructure. Evidence for supplementation specifically reversing GLP-1-associated hair loss is limited, but clinical use is common and risk is low.
