Best Supplements to Take with GLP-1 Medications (2026 Guide)
Evidence-based supplement recommendations for Ozempic, Wegovy, and Mounjaro users. Protect muscle, fix nutrient gaps, reduce side effects.
GLP-1 medications like Ozempic, Wegovy, and Mounjaro have transformed weight loss — but they create specific nutritional gaps that most users don't know about. Here are the evidence-based supplements every GLP-1 user should consider.
The Core Stack
Protein (Essential)
GLP-1 users lose up to 40% of weight as muscle without adequate protein. Aim for 1.0–1.2g per kilogram of body weight daily.
Vitamin D3 + K2
Reduced food intake often means reduced vitamin D. Studies show GLP-1 users are 2.5x more likely to be deficient.
Magnesium Glycinate
Critical for muscle function, sleep, and reducing constipation — one of the most common GLP-1 side effects.
B12 (Methylcobalamin)
GLP-1 medications can impair B12 absorption. Sublingual B12 bypasses this issue.
Omega-3 Fatty Acids
Supports heart health, reduces inflammation, and may help preserve lean mass during weight loss.
What to Avoid
Not all supplements are appropriate for GLP-1 users. Avoid high-dose iron unless prescribed, and skip any "weight loss" supplements that may interact with your medication.
FAQ
Do I need all of these? Start with protein and a quality multivitamin, then add based on your specific symptoms and bloodwork.
Can I take these with my medication? Yes, but time supplements at least 2 hours apart from your medication for optimal absorption.
