Muscle Support
This is the most important and underappreciated category for GLP-1 users. Resistance training combined with creatine supplementation is the most evidence-supported strategy for preventing lean mass loss during GLP-1 therapy. Creatine monohydrate has decades of safety data and works best when taken consistently at 3–5g per day.
How we chose these products
Every product in this category is assigned an evidence tier — Strong, Moderate, or Emerging— based on the clinical research behind the key ingredient category. Products labeled “GLP-1 Specifically Labeled” are formulated or marketed directly for GLP-1 medication users.
Our composite score weights evidence tier, Amazon rating, and review volume. Products are sorted by composite score by default. We earn affiliate commissions on purchases, which does not influence our ratings.
What to look for
Creatine monohydrate is the single most evidence-supported supplement for muscle preservation during GLP-1 therapy. Take 3–5g daily — no loading phase is necessary. Don't be misled by expensive 'advanced' creatine formulas; monohydrate is what the research uses.
Essential amino acids (EAAs) and leucine-rich formulas can help maintain muscle protein synthesis even on low calorie intake. These are particularly useful if you're struggling to hit protein targets from food and protein shakes alone.
Resistance training is more important than any supplement for muscle preservation. Even 2–3 sessions per week of progressive resistance training dramatically reduces lean mass loss during GLP-1-induced weight loss.

Frequently asked questions
How much muscle do you lose on Ozempic or Wegovy?
Clinical studies show that without deliberate intervention, 25–60% of total weight lost on GLP-1 medications can come from lean muscle mass rather than fat. The exact percentage varies based on protein intake, physical activity, and individual factors. This is why muscle preservation strategies are considered essential alongside GLP-1 therapy.
Does creatine actually prevent muscle loss on GLP-1 medications?
Creatine monohydrate has strong evidence for preserving muscle mass during caloric restriction and is specifically being studied for GLP-1 users. It works by improving the energy available to muscle cells, which supports both muscle maintenance and resistance training performance. The evidence for creatine in this context is stronger than any other single supplement.
How much creatine should I take on Ozempic?
The research-supported dose for muscle preservation is 3–5g of creatine monohydrate daily, taken consistently. No loading phase is needed. Take it with food to minimize any potential GI discomfort — though GI side effects are uncommon with monohydrate at maintenance doses.
Can I build muscle while on Wegovy or Mounjaro?
Building muscle while in a caloric deficit (as most GLP-1 users are) is very challenging. The realistic goal for most users is muscle preservation, not gain. However, beginners to resistance training can often experience 'newbie gains' even in a deficit. Adequate protein (1.2–1.6g/kg), creatine, and consistent resistance training are the three pillars.
