How deep is the trial record for creatine, and what does NIH say about it

PubMed holds 732 randomized-trial papers on creatine supplementation, one of the deepest records in self-improvement. Two NIH pages describe its benefit and safety, and they do not use the same tone.

Whitepill finding

On 30 October 2026, PubMed held 732 randomized-trial papers on creatine supplementation, against none on BPC-157. NIH's Office of Dietary Supplements (April 2024) calls it one of the most thoroughly studied supplements for sports performance. These counts show depth of record, not benefit for you.

PubMed counts read 30 October 2026 and ClinicalTrials.gov 2 November 2026; NIH statements from pages updated April 2024 and January 2021, read 2 November 2026.

The short version

Creatine: claims against the recordwhat gets said, and what the record shows, read 30 October 2026

What is creatine?

NIH's NCCIH calls creatine an amino acid produced by the body and a popular dietary supplement.[1] The Office of Dietary Supplements calls it one of the most thoroughly studied and widely used supplements to enhance exercise and sports performance.[2]

That is a much stronger record than a peptide with none. Where it sits against other topics is on the evidence ladder.

How deep is the trial record?

PubMed holds 732 papers typed as randomized controlled trials and 173 systematic reviews or meta-analyses for creatine supplementation.[3]

Papers typed as randomized controlled trials, and as systematic reviews or meta-analyses, for the evidence ladder's creatine query, read 30 October 2026. Counts of tagged papers, not effect or quality.

The tag is PubMed's own publication type.[4] Compare that with BPC-157, which has none typed as such, though a count still says nothing about who was studied or how large any effect was.

Every PubMed paper matching the query, whatever its type, beside the trial-typed slice: about 23 percent.

What else is registered?

ClinicalTrials.gov lists 389 interventional studies matching creatine and supplementation.[5] A registration is a plan on file, and we have not assessed any of them.

What does NIH say it does?

The ODS sheet lists creatine as supporting short-term, mainly anaerobic activity, with numerous clinical trials generally showing a benefit for high-intensity, intermittent activity and potential variation in individual responses.[2] It says it is of little value for endurance sports.

Read the reasoning

It also says other forms of creatine have not been proven to be better than creatine monohydrate for muscle creatine levels, digestibility, product stability or safety. NCCIH is more guarded, saying creatine may somewhat enhance the effects of exercise on strength, muscle mass and endurance.[1]

How to read a creatine claim
1. What was the goal? The NIH pages tie the benefit to short, intense, repeated efforts, not endurance.
2. Which form? The ODS sheet says other forms are not proven better than creatine monohydrate.
3. Check the page's age. NIH's two pages differ.
4. Hidden ingredients are a supplement-wide problem, so who made the product matters.
5. Kidney or liver conditions: ask a clinician first.

What do the NIH pages say about safety?

ODS says creatine is considered safe for short-term use by healthy adults, and that long-term oral supplementation does not impair renal function in healthy athletes. It lists weight gain due to water retention among reported adverse effects, with anecdotal reports of nausea, diarrhea and muscle cramps.[2]

Read the reasoning

NCCIH, on a page updated in January 2021, says there were reports creatine may impair liver and kidney function, and that its long-term effects have not been well studied.[1] The same NCCIH page warns that dangerous hidden ingredients are an increasing problem in products promoted for bodybuilding.

Two NIH pages on creatine, by date: NCCIH, Jan 2021 (long-term not well studied), then ODS, Apr 2024 (safe short-term, healthy adults), then Both agree (check with a clinician)NCCIH, Jan 2021long-term not well studiedODS, Apr 2024safe short-term, healthy adultsBoth agreecheck with a clinician
The older NCCIH page and the newer ODS page word creatine's safety differently. The page shows both, with dates, instead of picking the friendlier one.

The two pages are different ages and tones, which is why the safety question belongs with a clinician who knows your kidneys and your medicines.

Method

PubMed counts are the evidence ladder's own for creatine supplementation, read 30 October 2026, and ClinicalTrials.gov interventional studies matching the stated terms, read 2 November 2026. NIH statements are quoted or closely paraphrased from the ODS fact sheet (updated 1 April 2024) and the NCCIH page (last updated January 2021), both read in full on 2 November 2026. Dosing and loading schedules that the ODS table prints are deliberately not copied.

Queries are broad and will include off-topic papers, and publication-type tags can be loose, so treat the counts as depth of record (our grading rules are on the methodology page, and every comparison lives on the ladder hub). Nothing here measures effect size or study quality, covers dosing or products, or is medical advice.

FAQ

How many randomized trials are there on creatine?

PubMed held 732 papers typed as randomized controlled trials and 173 systematic reviews or meta-analyses for the evidence ladder's creatine supplementation query on 30 October 2026.

Is creatine proven to work?

NIH's Office of Dietary Supplements says numerous clinical trials generally show a benefit for high-intensity, intermittent activity, with variation in individual responses, and that it is of little value for endurance sports.

Is creatine safe?

ODS says it is considered safe for short-term use by healthy adults. NCCIH, on an older page, says there were reports it may impair liver and kidney function and that long-term effects have not been well studied. A clinician can weigh that for you.

Does a high trial count mean it works for me?

No. It means the record is deep. Effect size, study quality and your own situation are separate questions for a clinician.

Bottom line

Creatine has one of the deepest trial records in the scene, and NIH ties its benefit to short, intense efforts while describing safety in two different tones. Use the count to see that the record exists, then ask a clinician about you.
