Best Supplements To Support Your GLP-1 Journey
GLP-1 medications can change your body but the right supplements protect what matters most. We reviewed dozens to find the ones that actually support muscle retention.
If you're on a GLP-1 receptor agonist you already know these medications are powerful tools for weight management. But here's what most people don't talk about: rapid weight loss on GLP-1s doesn't just burn fat — it can also strip away lean muscle, deplete critical nutrients, and leave gaps in your long-term health.
Studies show that up to 40% of the weight lost on GLP-1 medications can come from lean muscle mass — not fat. Add in reduced appetite, smaller meals, and changes in nutrient absorption, and it becomes clear that supplementation isn't optional — it's essential.
That's why we reviewed over 30 of the most popular supplements used by people on GLP-1 medications. We reviewed third-party lab results, verified ingredient sourcing, analyzed clinical dosing for effectiveness and results.
After thorough review, we confidently ranked the top 5 supplements for your GLP-1 journey — and OMNI Creatine Gummies emerged as the clear #1 for muscle preservation, ease of use, and overall results.
Inside this guide, you'll see exactly how each pick supports your body while on GLP-1 therapy — so you can lose fat, keep muscle, and protect your long-term health.

Our Review:
After a thorough ingredient review and analysis of third-party lab results, OMNI Creatine Gummies earned our #1 spot for GLP-1 support supplements in 2026. Each serving delivers a full clinical 3g dose of pure creatine monohydrate — the exact form and amount backed by over 1,000 peer-reviewed studies. Here's the reality most GLP-1 prescribers don't emphasize enough: without targeted supplementation, you could lose almost as much muscle as fat.
Muscle Preservation During GLP-1 Therapy: Research consistently shows that up to 40% of weight lost on GLP-1 medications can come from lean muscle mass. Creatine directly fuels the ATP-phosphocreatine system in muscle cells, helping your body hold onto lean tissue even in a caloric deficit. For anyone on Ozempic, Wegovy, Mounjaro, or Zepbound, creatine isn't a luxury — it's a necessity.
Energy & Performance on Reduced Calories: GLP-1 medications significantly reduce appetite, which means your body is operating on fewer calories. Creatine supplementation helps maintain workout intensity and daily energy levels by supporting your body's primary energy currency (ATP) — so you can stay active and strong even while eating less.
Bone Density Protection: Rapid weight loss — regardless of the method — is associated with decreased bone mineral density. Studies show that creatine combined with resistance training significantly improves bone health compared to training alone. This makes daily creatine a smart long-term investment while on GLP-1 therapy.
Cognitive Support: Some GLP-1 users report brain fog, fatigue, and reduced mental sharpness — particularly in the early weeks. Creatine has been shown to improve short-term memory, processing speed, and mental endurance, especially during periods of caloric restriction or stress.
Why OMNI? The gummy format eliminates every friction point. Many people on GLP-1s already deal with nausea and reduced appetite — choking down chalky powders or large capsules is the last thing you want. OMNI's gummies taste great, are easy on the stomach, and deliver the full clinical dose with zero hassle. Every batch is third-party certified by Eurofins, non-GMO, and free of artificial colors, sweeteners, and fillers.

OMNI scored highest across every category we reviewed — ingredient quality, clinical dosing, taste, convenience, and customer satisfaction.

OMNI delivers a full clinical 3g dose in a gummy format that's easy on sensitive stomachs, every batch is third-party tested by Eurofins, and the formula is free of artificial dyes, fillers, and sugar. No other product matched that combination of efficacy, purity, and ease of use for GLP-1 users.
GLP-1 works by reducing appetite and slowing gastric emptying. While incredibly effective for weight loss, this means you're eating significantly less food — and getting fewer nutrients. Research shows that up to 40% of weight lost on GLP-1s can come from lean muscle, not fat. Targeted supplementation helps preserve muscle mass, maintain bone density, support digestive health, and fill nutritional gaps that smaller meals can't cover.
No. Some users may see a small initial increase on the scale (1–3 lbs) from intracellular water retention in the muscles — this is not fat gain and actually indicates the creatine is working. This water is stored inside your muscle cells, which supports performance and lean muscle preservation. It does not cause bloating or puffiness, and it stabilizes within the first week. The muscle you preserve with creatine actually supports a healthier metabolism long-term.
Yes! All five supplements on this list are safe to take together and alongside GLP-1 medications. However, we recommend spacing them throughout the day — take fiber at least 2 hours apart from other supplements and medications to avoid interference with absorption. Always consult your prescribing physician before starting any new supplement regimen.
