Signal reading for
Short, hard efforts during training (alongside resistance training)
Two meta-analyses of placebo-controlled trials (53 and 60 studies) found small but consistent gains in strength tests lasting under three minutes [3] [4], and both the ISSN position stand and the IOC consensus statement describe the same effect at 3–5 g/day, a dose this label matches [1] [2].
This reading is about brief, intense efforts only. Well-run trials showing no effect at 3–5 g/day in trained people would move it down; it says nothing about other uses.
What the research shows
- Pooled trials show better results in lifts and other strength tests shorter than three minutes; overall effect sizes are small (about 0.24–0.32) [3] [4].
- Sports bodies agree on dosing: an optional loading week of about 20 g/day in four doses, then 3–5 g/day [1] [2].
- A pooled review of kidney markers found no sign of kidney damage at the amounts and durations studied, though only six trials could be pooled [5].
What the hype says
- Social posts often present creatine as a daily habit for everyone, not only people who train.
- Marketing tends to frame newer or more expensive forms as upgrades on plain monohydrate.
- Online discussion often presents focus and mental energy as settled uses, which is a separate and much thinner question.
Hype is described in our words, not quoted, and is not a claim by this site.
The short version
- One scoop is 5 g of micronized creatine monohydrate and nothing else; the tub holds 100 scoops.
- $21.50 on Sep 30, 2026, which works out to about $0.22 per 5 g serving.
- The research dose and the label dose line up; the effect in trials is real but modest, and it depends on actually training.
What the label shows
We read the Supplement Facts panel and the suggested-use text from the images on the Amazon listing for the 500 g unflavored tub on Sep 30, 2026.
| Ingredient | Amount per serving | What to know |
|---|---|---|
| Creatine monohydrate (micronized) | 5 g | The form used in nearly all of the research. "Micronized" refers to particle size, which mainly affects how easily it mixes. |
| Other ingredients | None | No flavoring, sweetener or fillers listed on the unflavored tub. |
| Servings per container | 100 | Serving size is one scoop (5 g); net weight 500 g. |
The label suggests an optional loading phase (one scoop four times daily for days 1–5) followed by one scoop daily, each mixed with 6–10 oz of water. It carries a warning that the product is for healthy adults 18 or older and that people who are pregnant, nursing, taking medication or managing a medical condition should consult a healthcare professional first. The tub prints "third party tested" but names no certifier, and we found no certification seal we could verify, so our fact sheet lists none.
What the research shows
Pooled reviews. Two systematic reviews with meta-analyses from the same research group looked only at randomized, placebo-controlled trials with strength tests lasting less than three minutes. The upper-body analysis pooled 53 studies (563 people taking creatine, 575 controls) and found an overall effect size of about 0.32, with bench press around 0.27 [3]. The lower-body analysis pooled 60 studies (646 and 651 people) and found an overall effect size of about 0.24, with squat and leg press close to 0.3 [4]. In plain terms, these are small-to-moderate average differences, and in both analyses the effect did not depend on age, sex, dose or duration within the ranges tested. Many of the pooled trials paired creatine with a training program, and the practical benefit shows up in what people can do during training sessions, not as an effect of the powder alone.
Position and consensus statements. The International Society of Sports Nutrition's 2017 position stand summarizes a large body of trials in which creatine raised muscle creatine stores and improved high-intensity exercise performance, and it describes short- and long-term use as well tolerated in healthy people [1]. The 2018 International Olympic Committee consensus statement on supplements describes benefits for strength and repeated high-intensity exercise capacity, gives the same loading and 3–5 g/day maintenance protocol, and notes that loading can bring some water retention [2]. Several authors of the ISSN papers disclose ties to creatine manufacturers, which the papers state openly; the IOC statement and the independent meta-analyses reach similar conclusions.
Safety questions. A 2021 ISSN review addressed recurring concerns (water retention, kidneys, cramping, hair) and concluded that at recommended doses the evidence does not support the common worries in healthy people [6]. An independent 2019 meta-analysis of kidney markers reached a similar conclusion for the amounts and durations studied, but it could pool only six trials [5]. The same ISSN review notes that creatine can raise blood or urine creatinine, a routine lab value used to estimate kidney function, without that rise reflecting a drop in kidney function [6]; it is still worth mentioning to whoever orders your bloodwork. That review also concludes that loading is optional, since 3–5 g/day on its own also raises muscle creatine stores.
Study dose vs. label dose
In the research
3–5 g/day
Creatine monohydrate, often after 5–7 days at about 20 g/day in four doses; trials ran from days to months [1] [2]
One serving of this product
5 g
One scoop of creatine monohydrate per the Supplement Facts panel
Where the hype comes from
Creatine is one of the few supplements where the lab, the trials and the sports bodies broadly agree, and that credibility tends to travel. It now shows up in conversations about daily routines, focus and general wellness, sometimes with the implication that the strength research covers those uses too. It does not: the reading on this page is for short, hard efforts in people who train. Marketing also leans on newer forms, blends and flavored versions, while nearly all of the evidence summarized above used plain creatine monohydrate like the powder in this tub.
People with a kidney condition, or who take medicines that affect the kidneys, should talk with a clinician before starting creatine; the reassuring safety data come mostly from healthy adults. The label limits use to adults 18 and older.
Price and where it is sold
On Sep 30, 2026 the Amazon listing for the 500 g (100-serving) unflavored tub showed $21.50, in stock, shipped by Amazon and sold by eSupplements. The listing marked the item as non-returnable for food-safety reasons. The same listing offers several flavored versions with fewer servings per tub. See the listing on Amazon.
Who should look elsewhere
- Anyone under 18, and anyone pregnant or nursing, per the label's own warning.
- People with a kidney condition or who take prescription medicines, until they have asked a clinician or pharmacist.
- People who want a product with a named third-party certification such as NSF Certified for Sport; this tub does not show one we could verify.
- Anyone who does not do resistance or high-intensity training: the reading here is about performance in those sessions.
