Are you strength training?
Creatine works best with it. On its own, it adds little muscle.
Kidney disease, pregnant or breastfeeding?
Talk to your doctor first. The research doesn’t cover you yet.
Thinking gummies?
Skip them for now. Lab tests keep finding less creatine than the label says.

BulkSupplements Creatine Monohydrate
★★★★★4.7✓ The cheapest certified option we found in the US.
! It doesn’t say where the raw creatine comes from.
Sports Research Creapure® Creatine
★★★★★4.6✓ Made from Creapure®, a German raw material you can trace.
! Costs about 2 to 3 times the value pick.
Momentous Creatine
★★★★★4.3✓ NSF Certified for Sport, and the brand publishes its own purity spec.
! It switched away from Creapure in June 2026.
Thorne Creatine
★★★★★4.2✓ NSF Certified for Sport, from a brand many clinicians stock.

Not recommended
What we’d skip
Optimum Nutrition Micronized Creatine
The brand says it’s certified, but we couldn’t confirm it in the certifier’s database yet.
Create Creatine Gummies
Certified, but gummies lose potency. A 2026 class action alleges under-dosing; Create disputes it.
CON-CRĒT Creatine HCl
Not monohydrate. There’s no evidence HCl works better.
EcoWise Wellness and Vidabotan gummies
No creatine detected in a 2025 US lab test (SuppCo).
Nutricost, Transparent Labs Creatine HMB and Beast Bites are unclear too. See all 12 →
Why we’re strict about creatine
Creatine breaks down in moist formats like gummies. Powder stays stable for years. That’s why the failures cluster in gummies.
gummy brands missed their label claim
NOW Foods lab test, 2024 →creatine found in 2 gummy brands sold on Amazon US
SuppCo lab test, 2025 →Does it actually work?
Muscle and strength, with training
22 trials, 721 adults aged 57–70: about 1.4 kg more lean mass than training alone.
Chilibeck 2017, meta-analysis →Memory
Improved in adults aged 66–76, with little effect in younger people.
Prokopidis 2023, meta-analysis →Brain and Alzheimer’s
A 20-person pilot raised brain creatine. There was no placebo group.
Smith 2025, pilot →How to buy it right in the US
- Pick plain creatine monohydrate powder.
- Look for the NSF Certified for Sport mark, then check the lot number at nsfsport.com.
- Buy from the brand or its official store, not a random marketplace seller.
- Store it dry. Moisture breaks creatine down.
Questions
Is creatine a steroid?
No. Creatine is a compound your body makes from amino acids and gets from meat and fish. It isn’t a hormone.
Does creatine cause hair loss?
The only trial that measured hair (12 weeks, 2025) found no change in DHT or hair. The worry traces to a 2009 study that never measured hair.
Is creatine bad for your kidneys?
Studies in healthy people show no harm to kidney function. Creatine raises creatinine on blood tests, which can look like a kidney problem, so tell your doctor you take it. People with kidney disease should ask their doctor first.
Should women take creatine?
Women store less creatine than men. Trials in older women show muscle benefits when it’s paired with strength training. The largest 2-year trial found no effect on bone density. If you’re pregnant or breastfeeding, ask your doctor first.
Creatine gummies or powder?
Powder. It stays stable for years, while creatine breaks down in moist formats. Independent tests in 2024 and 2025 found gummies with less creatine than labeled, and some with none.
Is creatine HCl better than monohydrate?
No evidence says so. Monohydrate is the form used in almost all the research.
How much did the studies use?
Most trials used 3 to 5 grams a day, some after a short higher-dose “loading” week. This describes the research, not advice for you.
