Is creatine safe to take with Ozempic?

Yes, creatine is generally considered safe to take with Ozempic. The reviewed research does not describe a direct interaction, and a 2025 review in Obesity pillars notes strength benefits from creatine monohydrate alongside resistance training. Still, a 2026 article in Clinical nutrition says no randomized clinical trial has directly evaluated the combination, so tell your prescriber you use it.

That is not a green light to double your dose and hope for the best. Ozempic slows digestion and changes how food feels, according to the NHS, so a supplement that once sat fine in your stomach might behave differently now.

Can you take creatine with Ozempic?

Ozempic is the brand name for semaglutide when it is prescribed for type 2 diabetes, and it works by lowering appetite, slowing digestion, and helping blood sugar stay steady after meals, as explained on the NHS semaglutide page. Creatine is a supplement that has been studied for muscle energetics. A 2026 article in Clinical nutrition hypothesizes that rapid weight loss on GLP-1 therapy may create conditions of increased skeletal-muscle bioenergetic vulnerability, and that creatine is a biologically plausible adjunct to support muscle energetics and function. The same article is clear that this is hypothesis-generating and that no randomized clinical trial has directly evaluated creatine supplementation during GLP-1-based weight loss. A 2025 review in Obesity pillars adds that when combined with resistance training, whey protein can help preserve lean body mass, with additional strength benefits from creatine monohydrate and β-Hydroxy β-Methylbutyrate. So the short answer is yes, you can take it, but the evidence is supportive rather than proven.

Does Ozempic interact with creatine?

The reviewed literature does not describe a direct chemical interaction between semaglutide and creatine. The 2025 review in Obesity pillars frames creatine as one of several supplements that may support lean mass and strength alongside training during GLP-1 treatment. The 2026 article in Clinical nutrition also treats creatine as a plausible adjunct rather than a risk. That said, the absence of a flagged interaction is not the same as a large safety trial in people taking both. If you take other medicines or have kidney concerns, your clinician is the right person to ask.

Creatine and Ozempic side effects

Common side effects of semaglutide include feeling sick, vomiting, constipation, diarrhoea, feeling tired, itchy or red skin at the injection site, and hair loss, as listed by the NHS. Serious side effects are rare but can include an inflamed pancreas, which causes severe pain in the stomach or back that does not go away. The NHS advises speaking to a pharmacist or doctor if you have side effects that bother you or do not go away, and keeping taking your medicine unless advised to stop. None of the sources here link creatine to those side effects.

How much creatine should I take on Ozempic?

The sources do not give a specific dose for creatine during GLP-1 therapy. The 2025 review in Obesity pillars does give a protein target of 1.2 to 2.0 grams per kilogram per day to help meet daily protein recommendations. For creatine itself, follow the amount printed on your label.

Ours is Hull, an unflavored creatine monohydrate powder with 5 g in a scoop and nothing else in the tub.

What should I eat for muscle on Ozempic?

A 2025 review in Current opinion in clinical nutrition and metabolic care notes that up to 40 percent of total weight loss on GLP-1 receptor agonists can come from fat-free mass, though fat-free mass includes more than just muscle. The same review says resistance training and adequate protein can mitigate muscle loss, but the evidence for their efficacy specifically during GLP-1 therapy is mixed. If those measures are not enough, the review names branched chain amino acids, creatine, leucine, omega-3 fatty acids and vitamin D as nutrients that may be beneficial.

Support	Typical daily amount	Why it matters	What to eat for it
Protein	1.2 to 2.0 g per kg body weight	Helps preserve lean mass during weight loss	Chicken, fish, eggs, whey, lentils
Creatine	Standard label dose	May support muscle energetics and strength with training	Red meat, fish; supplements
Vitamin D	Standard label dose	Named as a nutrient that may help muscle preservation	Oily fish, fortified milk, sun
Omega-3 fats	Standard label dose	Named as a nutrient that may help muscle preservation	Salmon, sardines, walnuts, chia

What else should I watch on Ozempic?

If constipation is the main problem, we wrote about how to fix constipation on Ozempic. If you are curious about micronutrients, we looked at whether Ozempic depletes B12. And if you are sweating more or eating less than usual, best electrolytes for GLP-1 is a handy read. If your appetite has shrunk and your nails have noticed, the thing we happen to make is Keel, a two-capsule-a-day digestive support with enzymes, probiotics, ginger, peppermint, methylated B12, folate, B6, iron, zinc, magnesium, biotin, D3 and BioPerine.

Should I tell my doctor I take creatine?

Yes. Bring your full list, including supplements, to your appointment. The NHS advises asking a pharmacist or doctor for advice if you are not sure how to use your medicine or if you have any problems using it, according to the NHS semaglutide page. Your prescriber can weigh creatine against the rest of your plan.
