Biotin for hair loss on GLP1 medicines

Why Biotin Matters When You’re on Mounjaro or Wegovy


Many people using GLP-1 medications like Mounjaro and Wegovy notice increased hair shedding during the first few months of weight loss. It’s often caused by a combination of calorie reduction, hormonal shifts, and nutrient changes, not the medication itself. That’s where biotin supplements might help.


Biotin plays an essential role in cell growth, energy production, and keratin formation, all of which support strong, healthy hair and nails. Supplementing with biotin can help bridge any nutritional gaps and may promote thicker, more resilient strands over time.


The Benefits of Biotin for GLP-1 Users


Adding a high-quality biotin supplement may help:


  • Support natural hair growth and reduce breakage during rapid weight loss

  • Strengthen brittle nails that can become weaker on lower-calorie diets

  • Improve skin health and elasticity through better keratin production

  • Maintain energy metabolism when your diet changes on Mounjaro or Wegovy


What Type of Biotin Works Best


Most biotin supplements contain between 5,000–10,000 mcg per serving. Both capsules and gummies are effective, and it mostly comes down to preference. Some formulas also include zinc, selenium, or collagen peptides for added support.


If you’re looking for an all-rounder for hair and skin nutrition, choose a multi-ingredient blend with biotin plus vitamin C, B12, or hyaluronic acid for extra absorption and hydration benefits.


How to Choose the Best Biotin Supplement for Mounjaro and Wegovy


When comparing options, check for:


  • Verified reviews and consistently high ratings on Amazon

  • Transparent ingredient labels with clear dosage information

  • No unnecessary fillers, sugars, or artificial dyes

  • Reasonable pricing, the best supplement is one you’ll actually keep taking


How to Use Biotin when taking GLP-1s


Because GLP-1s can suppress appetite, try taking your biotin supplement with a protein-rich snack or meal to support nutrient absorption. Consistency matters; most users see results after about 8–12 weeks of daily use.


Pairing biotin with a balanced diet, hydration, and adequate protein intake gives your hair the best chance to recover and thrive.


TL;DR


Biotin isn’t a miracle cure for GLP-1 hair loss, but it can be a smart, supportive addition to your daily routine. Combined with a healthy diet and patience, it may help your hair feel stronger and fuller as your body adapts to weight loss on Mounjaro or Wegovy.


*Everyone’s body responds differently, so always speak to your prescribing professional before starting new supplements.

Is Biotin the Secret to Stopping GLP-1 Hair Shedding?


The hair loss posts on social media are a bit worrying, right? You start your Mounjaro or Wegovy journey, and suddenly every post in your feed is someone talking about thinning hair or extra shedding in the shower. Even if it’s temporary, it’s hard not to panic a little.


That’s why so many GLP-1 users are turning to biotin supplements. Biotin (also known as vitamin B7) helps your body make keratin, the key protein that keeps your hair, skin and nails strong. When your appetite drops and your nutrient intake changes, biotin levels can dip, leaving hair a bit more fragile.


Taking a biotin supplement won’t magically stop shedding overnight, but it can support healthy regrowth and strength while your body adjusts. We’ve rounded up the most-loved biotin products on Amazon to help you find one that fits your routine.
