Many people take creatine to build muscle and boost workouts. They often wonder if it also helps their heart health. A new review looked closely at whether creatine changes cholesterol or triglyceride levels. The answer is clear. Creatine does not seem to lower or raise these blood fats in a meaningful way.
This matters because high cholesterol and triglycerides raise the risk of heart disease. Many adults check these numbers yearly. They want simple ways to improve them. Creatine is popular and widely available. People hope it might help with more than just strength.
But here is the twist. Past studies have suggested creatine could influence metabolism. Some thought it might improve how the body uses energy. That led to questions about its effect on blood lipids. This review tested that idea with the strongest method available.
The researchers used a meta-analysis. This means they combined data from many randomized trials. Randomized trials are the gold standard. They compare creatine to a placebo, which looks like creatine but has no active ingredient. This design helps isolate the true effect.
Creatine works like a rechargeable battery for your muscles. It helps recycle a molecule called ATP, which powers short bursts of activity. Think of it as a quick energy reserve. The body makes creatine naturally, and you can also get it from meat and fish. Supplements add more to the tank.
The review included eight randomized trials. All studies tested oral creatine against a placebo in adults. The researchers searched major medical databases through June 2025. They followed strict guidelines to reduce bias. They looked at changes in total cholesterol, LDL, HDL, and triglycerides.
Here is what they found. Total cholesterol did not change in a meaningful way. The average difference was about 3 mg per deciliter, which is tiny. LDL, often called bad cholesterol, also did not change. HDL, the good cholesterol, stayed the same. Triglycerides did not move either.
These results mean creatine is unlikely to help or hurt your lipid profile. The changes were small and not statistically significant. In plain language, they could be due to chance. The certainty of evidence was low for some outcomes and very low for others. That means we cannot rely on these numbers to guide care.
This does not mean creatine is unsafe for your heart.
The review noted some methodological limits. Some studies had issues with how they randomized participants. Others had incomplete reporting of results. These weaknesses lower confidence in the findings. They also show why more high-quality trials are needed.
An expert perspective is helpful here. The researchers concluded that creatine does not have clinically relevant effects on lipids. They recommend future studies with larger samples and better methods. This aligns with current guidelines that focus on diet, exercise, and proven medications for cholesterol control.
What does this mean for you? If you take creatine for muscle or exercise benefits, you can continue. It is unlikely to change your cholesterol numbers. If you are worried about heart health, talk to your doctor about proven strategies. These include a balanced diet, regular activity, and appropriate medications when needed.
This review has limits. It included only eight trials, and some were small. The evidence quality was low overall. More research is needed to confirm these results. Future studies should include diverse populations and longer follow-up.
What happens next? Researchers will continue to study creatine and heart health. Larger trials with better methods could provide clearer answers. For now, creatine remains a safe option for muscle performance, but not a tool for improving cholesterol.
