Fix this week

  1. Retire or relabel the 1 g SKU. Amazon B0C8KRX6K6 is titled “High Strength” and carries the same performance claims as the 5 g product at one fifth of the dose. The Shopify page (the 1,000 mg product, per its URL) never states the dose.
  2. Drop the IMPROVED HYDRATION bullet from Shopify and the 1 g listing. No trial tests “reduce the risk of dehydration,” and nothing supports “Creatine for men.”
  3. Rename FATIGUE REMEDY and rewrite RECOVERY. “Remedy” reads as treating a condition, and two meta-analyses found no effect on soreness. Wording is below.
  4. Correct listing data before relisting (both ASINs show “Currently unavailable”). The 5 g listing gives 50 g as the weight of 120 gummies that should hold 150 g of creatine, lists sodium citrate ahead of creatine, and says “100% sugar free” while listing tapioca syrup. The 1 g listing’s benefit field reads “Muscle Therapy.”
  5. Add age verification for New York orders. NY General Business Law 391-oo bars selling muscle-building supplements to under-18s and names creatine.

Rubric, graded strictly on the claim as worded: A = consistent RCTs or meta-analyses at the labeled dose and population; B = supportive but narrower or mixed; C = limited, or the wording promises more than was measured; D = no human evidence, or contradicted.

Method: claims copied verbatim from the three listings on 2026-11-09; PubMed searched for human RCTs and meta-analyses; every PMID checked against PubMed; study design, funding and author conflicts noted for each source.

Evidence-matched wording

INCREASED PERFORMANCE A

Creatine monohydrate (5 g daily) can help increase strength and power in short, high-intensity exercise such as weightlifting, when combined with training.

FATIGUE REMEDY → WORK CAPACITY A

Creatine can help you complete more work in a training session and resist fatigue across repeated high-intensity efforts.

RECOVERY → ENERGY BETWEEN EFFORTS A

Creatine raises muscle phosphocreatine stores, the fuel your muscles draw on for repeated high-intensity efforts. Drops the soreness and muscle-damage language.

IMPROVED HYDRATION B

Recommended: remove. If kept: Creatine draws water into muscle cells. It is not a hydration product; drink fluids as usual.

Builds Muscle B

5 g SKU only: Supports lean-mass gains when combined with resistance training.

Pre Workout Gummies → Daily Creatine Gummies A

Take 4 gummies at any consistent time of day. Benefits build over about 3–4 weeks of daily use.

Verbatim claims

INCREASED PERFORMANCE
“Studies show Creatine helps to increase the amount of energy available to muscles during exercise, which can help to improve muscle strength and power. This is particularly true for activities that require short bursts of high-intensity effort, like weightlifting and sprinting.”
FATIGUE REMEDY
“Studies show Creatine has been found to enhance exercise performance in a number of ways. For example, it can help to increase the amount of work that can be performed during a single training session, and can help to reduce fatigue during high-intensity exercise.”
RECOVERY
“Research has shown that Creatine has been found to improve recovery after exercise, reducing muscle damage and soreness. This is likely due to the fact that creatine helps to increase the amount of energy available to muscles during exercise, which can help to reduce the amount of damage that occurs during training.”
IMPROVED HYDRATION
“Creatine for men has been found to help improve hydration levels in the body, particularly in muscle cells, which can help to improve physical performance and reduce the risk of dehydration.”

Evidence by claim

Strength and power. Kazeminasab et al. 2025, meta-analysis of 69 RCTs (1,937 adults): creatine plus resistance training improved bench or chest press (+1.43 kg), squat (+5.64 kg), vertical jump and Wingate peak power, with no overall change in handgrip or leg press. Gains were significant in men but not in the smaller female subgroups; one author advises a creatine brand. Lanhers et al. 2017, meta-analysis of 53 RCTs, found upper-limb strength gains across populations. The ISSN position stand (Kreider et al. 2017, an expert review whose authors report creatine-industry ties) sets the maintenance dose at 3–5 g/day, so the 1 g SKU sits below every studied maintenance dose.

Work capacity. The ISSN position stand reports that creatine increases the work done across repeated maximal sets and sprints. The body copy under FATIGUE REMEDY says this accurately; the headline word “remedy” is the problem.

Recovery. Northeast and Clifford 2021, meta-analysis of 13 RCTs: no effect on soreness, strength recovery, range of motion or inflammation up to 96 hours; creatine kinase lower at 48 hours only. Doma et al. 2022, meta-analysis of 23 studies (469 participants, about 10% women; authors report no conflicts): damage markers were lower after a single hard bout but higher after weeks of use, and soreness differences were not significant. Jiaming and Rahimi 2021, meta-analysis of 9 RCTs: lower creatine kinase, with high heterogeneity and medium risk of bias flagged by the authors. No pooled analysis shows less soreness.

Hydration. Antonio et al. 2021 (ISSN expert review; authors report creatine-industry ties) concludes creatine does not cause dehydration or cramping and may increase water inside muscle cells. Dalbo et al. 2008 (narrative review) reaches the same view and cites small studies in the heat. No trial tested dehydration risk as an outcome, and none found a sex-specific effect.

Lean mass. Delpino et al. 2022, meta-analysis of 35 RCTs (1,192 participants): +1.10 kg with resistance training, no effect without exercise; men +1.46 kg, women +0.29 kg (not significant). Hence B for a general audience.

Timing. Creatine works by raising muscle stores over days to weeks, and a loading phase is optional (Antonio et al. 2021). Nothing in the evidence depends on taking it before a workout.

Form match. Nearly all of these trials used powder. The only gummy trial (Pereira et al. 2026, 32 female athletes, 5 g/day for 10 weeks) was randomized but open-label: the control group got neither creatine nor a placebo, the trial was not registered in advance, and a co-author advises the gummy’s maker. Claims carry over to a gummy only if each serving holds its labeled creatine through expiry, so this file links each lot’s assay and stability results once they are on hand.
