Does Creatine Affect Cholesterol Levels?

Creatine supplementation does not appear to meaningfully change cholesterol levels. The most comprehensive review of randomized trials found no statistically significant effect on total cholesterol, LDL, HDL, or triglycerides, and the overall certainty of evidence ranged from very low to low. A few smaller and older studies have hinted at modest shifts in specific lipid markers, but nothing consistent enough to call a real effect. If you are taking creatine for exercise performance or other reasons, your cholesterol panel is unlikely to notice.

What the Largest Pooled Analysis Found

A systematic review and meta-analysis of randomized placebo-controlled trials pooled results across multiple studies and found that creatine supplementation had no meaningful impact on any standard lipid marker. Total cholesterol shifted by roughly 3 mg/dL on average, LDL by about 4 mg/dL, and HDL barely moved at all. Triglycerides showed a slight upward trend of about 8 mg/dL, but with wide variability between studies and no statistical significance. In practical terms, these numbers are well within normal day-to-day fluctuation and far too small to change anyone’s cardiovascular risk category.¹

The review also rated the quality of the underlying evidence. For total cholesterol and triglycerides, certainty was classified as very low, meaning future research could easily change the conclusion in either direction. For LDL and HDL, certainty was rated low. That does not mean creatine definitely does nothing to lipids. It means the existing trial data, when pooled, do not support any confident claim that it does.

Earlier Studies That Suggested a Different Story

The idea that creatine might lower cholesterol traces back to a 1996 study that gave creatine monohydrate to men and women for twelve weeks and tracked their blood lipids. The results looked promising at first glance. Total cholesterol dropped by about 5 to 6 percent during the first eight weeks, and triglycerides fell by roughly 23 percent. VLDL cholesterol, the carrier that transports triglycerides, dropped by a similar amount.²

But the details matter. The total cholesterol reduction did not stick. By week twelve, it had returned to where it started. The triglyceride and VLDL reductions lasted longer, but the researchers themselves described the findings as “preliminary.” LDL and HDL showed no changes at all. And the study was small, without the kind of rigorous design that would let you draw firm conclusions. The authors suggested creatine “may modulate lipid metabolism in certain individuals,” which is a fair reading, but it is a long way from saying creatine lowers cholesterol.

Another trial looked at healthy men who were already doing aerobic training and added creatine to their regimen. After the study period, there were no differences between the creatine group and the placebo group in any lipid marker, including HDL, LDL, total cholesterol, VLDL, or triglycerides. The researchers concluded that creatine did not add anything to the lipid improvements that aerobic exercise alone provided.³

Triglycerides May Be the One Exception

If there is a consistent thread in the research, it involves triglycerides rather than cholesterol itself. A pilot study in older adults found that four weeks of creatine monohydrate supplementation led to a meaningful drop in fasting triglycerides, from about 100 mg/dL to roughly 84 mg/dL. Fasting glucose also fell modestly. But LDL, HDL, non-HDL cholesterol, and total cholesterol did not budge.⁴

These triglyceride findings are interesting because they echo the 1996 study’s results, and because triglycerides are an independent risk factor for heart disease that often gets less attention than LDL or total cholesterol. But a pilot study in a small group of older adults does not establish a treatment effect. When the meta-analysis pooled triglyceride data across multiple trials, the overall result was not significant, suggesting that whatever triglyceride-lowering effect might exist in some people, it is not reliable or large enough to show up consistently across populations.¹

So should you take creatine to lower your triglycerides? No. The evidence is too thin and inconsistent for that purpose. But if you are already taking creatine and happen to see a small dip in triglycerides on your next blood panel, the supplement could be a contributing factor.

What Happens Inside the Liver

Even though creatine does not reliably change what shows up on a standard blood lipid panel, there is a separate and genuinely interesting line of research about what creatine does to fat metabolism inside the liver. Your liver is responsible for about half of your body’s daily creatine synthesis, and the process consumes a molecule called S-adenosylmethionine, or SAMe. SAMe is also involved in many other metabolic pathways, including ones that influence fat storage. When you supplement with creatine, the liver does not need to make as much on its own, which frees up SAMe and reduces the production of homocysteine, a byproduct linked to cardiovascular risk.⁵

In animal studies, this mechanism has translated into real effects on liver fat. Rats fed a high-fat diet that also received creatine supplementation did not accumulate the excess liver fat, triglycerides, or cholesterol that their unsupplemented counterparts did. The high-fat diet alone drove liver total fat up by about 55 percent and liver triglycerides up by about 87 percent. Creatine prevented those increases.⁶ A separate study in neonatal piglets receiving total parenteral nutrition found that creatine supplementation reduced liver cholesterol concentrations, although not triglycerides or total fat.⁷

This is where the evidence gets genuinely promising but also genuinely premature. A narrative review of preclinical research concluded that creatine shows protective effects against metabolic-associated fatty liver disease at multiple stages, from early fat buildup to later inflammation and fibrosis.⁸ But these findings come from animal models and cell studies, not from human trials designed to measure liver fat directly. Liver cholesterol and blood cholesterol are connected but not the same thing. You can have a perfectly normal blood lipid panel and still accumulate fat in your liver, and vice versa. So the animal data, while encouraging, does not change the answer about what creatine does to the cholesterol numbers your doctor checks.

Creatine and Cardiovascular Risk Beyond Cholesterol

Cholesterol is just one piece of the cardiovascular risk picture, and some researchers have looked at whether creatine influences other relevant markers. One area of interest is inflammation. A study of repeated-sprint exercise in humans found that creatine supplementation blunted the rise in TNF-alpha and C-reactive protein, two inflammatory markers that spike after intense exercise. The placebo group saw significant increases in both markers up to an hour after exercise, while the creatine group did not.⁹ Chronic low-grade inflammation is increasingly recognized as a driver of atherosclerosis, so the idea that creatine could dampen post-exercise inflammation is relevant to heart health even though it is not about cholesterol per se.

Creatine also has some antioxidant properties. In rats, supplementation decreased plasma lipid peroxidation markers after acute exercise. Lipid peroxidation is a process where free radicals damage the fats in cell membranes and in circulating lipoproteins, and oxidized LDL is thought to be more harmful to blood vessels than regular LDL. Creatine inhibited the formation of malondialdehyde and lipid hydroperoxides in plasma, though its protective effect was less consistent in muscle tissue.¹⁰

These effects are not large enough or well-enough studied to recommend creatine as a cardiovascular supplement. But they add context: even if creatine does not change how much cholesterol is in your blood, it may influence what that cholesterol does once it is there. That is a hypothesis worth testing in larger human trials, not a claim you should act on today.

Why Your Blood Work Might Look Different After Starting Creatine

If creatine does not change cholesterol, why do some people report that their blood work shifted after they started supplementing? A few things could explain this. First, people who start creatine often simultaneously change their exercise habits, diet, or overall supplement stack. Those changes can easily move lipid numbers by a few points in either direction. Second, blood lipids fluctuate naturally from test to test. A difference of 5 to 10 mg/dL in total cholesterol between two draws can be pure measurement variability, not a supplement effect.

The blood work change that creatine genuinely does cause is an increase in serum creatinine, the waste product of creatine metabolism. A meta-analysis of randomized controlled trials found that creatine supplementation raised serum creatinine by an average of about 0.13 mg/dL.¹¹ This is not a sign of kidney damage. When you consume more creatine, your body naturally produces more creatinine as a breakdown product, and the kidneys filter it out. The increase is expected and benign. But if your doctor sees a creatinine level that is slightly above the reference range and does not know you take creatine, they might order follow-up kidney tests unnecessarily. Mention your supplement use before lab work to avoid that confusion.

On the liver side, a large cross-sectional analysis of people aged twelve and older found no significant link between creatine intake and standard liver markers like ALT, AST, GGT, albumin, or total bilirubin. Higher creatine intake also did not increase the odds of liver fibrosis, cirrhosis, or fatty liver disease.¹² So when your doctor pulls a comprehensive metabolic panel, creatine is unlikely to throw off any liver enzyme results either.

Should People on Statins or With High Cholesterol Worry

There is no published evidence that creatine interferes with statin medications or worsens outcomes for people who already have elevated cholesterol. The meta-analysis showing no effect on lipid markers included participants with a range of baseline cholesterol levels, and nothing in the data suggested that people starting with higher cholesterol fared differently. The animal studies on liver fat, if anything, point in a protective direction, though that has not been confirmed in humans managing hyperlipidemia.

If you are on a statin and considering creatine, the practical concern is really about muscle symptoms. Both statins and creatine affect muscle tissue, though in different ways. Statins occasionally cause muscle pain or weakness, and some people worry that adding creatine could complicate that picture. The pharmacological mechanisms are different enough that there is no established interaction, but this is a conversation worth having with whoever prescribes your statin, especially if you already experience muscle side effects from it.

How Creatine Differs From Supplements That Do Affect Cholesterol

Part of why people ask about creatine and cholesterol is that several other popular supplements have documented effects on blood lipids, and it is easy to assume creatine might do the same. Fish oil (omega-3 fatty acids), for example, is well established as a triglyceride-lowering agent, with effects large enough that prescription-strength formulations exist for that purpose. Red yeast rice contains a compound that works similarly to a statin. Plant sterols and stanols can lower LDL by blocking cholesterol absorption in the gut. Niacin, at pharmacological doses, raises HDL and lowers triglycerides, though its overall cardiovascular benefit has been questioned.

Creatine works through an entirely different metabolic pathway. It is stored primarily in skeletal muscle as phosphocreatine and serves as a rapid energy buffer during short bursts of intense activity. It is not involved in cholesterol synthesis, bile acid production, or intestinal cholesterol absorption in any direct way. The liver connection described earlier is real but indirect, operating through methyl-group metabolism rather than through the cholesterol pathway itself. So the lack of a consistent effect on blood cholesterol is not surprising from a mechanistic standpoint. Creatine does not target any of the processes that drive cholesterol levels up or down.

For someone trying to manage their lipid profile through supplements, creatine is essentially a non-factor. It will not help your cholesterol and, based on the best available evidence, will not hurt it either. That neutrality is actually reassuring for the millions of people who take creatine primarily for strength, power output, or recovery, because it means one less thing to monitor.
