Creatine monohydrate: what to look for on the label

If you are comparing creatine products at all, start with the ingredient name, the Supplement Facts panel, and an independent testing mark — not a marketing claim. NIH ODS says creatine monohydrate is the most widely used and studied form in supplements. FDA does not approve dietary supplements for safety or effectiveness before they are sold, so a seal such as NSF Certified for Sport or USP Verified is a way to check label contents and, in the sport program, certain banned substances. This is not medical advice, and it is not a reason to take creatine.

• Anyone looking for medical advice, a treatment plan or a dose. We will not provide those. A clinician should.
• People who want a product that is FDA-approved to treat a disease. FDA’s pages say dietary supplements are not approved as drugs before sale, and a product marketed to treat, cure or prevent a disease is regulated as a drug.
• Teenagers, people who are pregnant, and anyone with a medical condition or prescription medicines, unless a clinician has already been involved. NIH ODS and FDA both tell readers to talk with a health care professional first.
• Shoppers who will not read the label or check a certification database. The criteria below only help if you actually use them.

The NIH ODS consumer fact sheet on dietary supplements for exercise and athletic performance, updated March 22, 2021, describes creatine as a compound stored in muscles. It states that the body makes some creatine and that some also comes from animal foods, and that creatine monohydrate is the most widely used and studied form in supplements. The same fact sheet summarizes published research on certain kinds of short, intense activity and notes that creatine appears to have little value for endurance activities such as distance running. It also describes safety observations from studies in healthy adults and mentions water-retention-related weight gain and some uncommon individual reactions. Those are statements from a dated NIH ODS fact sheet, not instructions from us. The fact sheet also recounts amounts used in studies; we are not recommending those amounts, and you should not treat a study protocol as a personal dose.

FDA’s “FDA 101: Dietary Supplements” page and its questions-and-answers page both state that the agency does not approve dietary supplements for safety and effectiveness, or approve their labeling, before they are sold. Manufacturers are responsible for the safety of their products and for truthful labeling. Labels must include a Supplement Facts panel with serving size, servings per container, and the dietary ingredients and amounts per serving, plus a domestic contact for serious adverse-event reporting. FDA also says supplements should not replace a varied diet or a prescribed medicine, and that you should talk with a health care professional before using one. If a product is marketed to diagnose, treat, cure or prevent a disease, FDA treats it as a drug. Serving size is chosen by the manufacturer and does not require FDA approval, which is one more reason to read the panel rather than assume two tubs are equivalent.

NIH ODS also notes that some performance-supplement sellers use NSF Certified for Sport, Informed-Choice or the Banned Substances Control Group. We fetched NSF’s and USP’s official program pages for this guide. If you want to confirm a specific product, use the certifier’s current database, not a claim on social media.

• The product is labeled as a dietary supplement and has a Supplement Facts panel, as FDA requires.
• The dietary ingredient is named as creatine monohydrate if that is the form you intended to compare. NIH ODS identifies that form as the most widely used and studied in supplements.
• The amount per serving is stated clearly. FDA says the manufacturer, not FDA, chooses serving size.
• A recognizable third-party mark is present, and you can find the product in that certifier’s current database.
• You have a plan to talk with a clinician before using it, especially if you take other medicines or have a health condition.
