Best Collagen Supplements for Ozempic Users

Hair thinning and skin changes are among the more distressing side effects of GLP-1 therapy — and they're not rare. The phenomenon is called telogen effluvium: rapid weight loss triggers hair follicles to enter a resting phase early, causing increased shedding 2–4 months after the weight loss begins. Tirzepatide (Mounjaro/Zepbound) explicitly lists hair loss in its FDA labeling.

The good news: it's almost always temporary. But you can support recovery and minimize severity with the right nutritional approach. Adequate total protein intake is the most important factor — hair is made of keratin, and protein deficiency is a primary driver. Collagen peptides offer additional support with moderate evidence: they provide glycine and proline, amino acids critical for collagen and keratin synthesis that are under-represented in most protein supplements.

These are the collagen products we recommend for Ozempic and Wegovy users dealing with hair and skin changes.
