The only question that matters

Why does the ingredient
list matter?

The problem

Most creatine has 6–14 ingredients.

At best, the extras are useless. At worst, they're why you read the label twice and still weren't sure what you were putting in your body. Proprietary blends exist to hide dosing, not improve results. Fillers exist to cut cost. Neither is there for you.

The research

Every significant study used monohydrate.

Not creatine HCL. Not buffered creatine. Not "enhanced matrix" creatine. Every credible finding on strength, power output, recovery, and cognitive performance used creatine monohydrate — this exact molecule. The research is on monohydrate because monohydrate works. We didn't add anything to it.

The standard

Every batch tested. Results public.

The supplement industry asks you to trust them. We ask you to verify. Every production run is tested by an independent lab before a single unit ships — 99.9% purity, zero banned substances. The Certificate of Analysis is public. Your lot number is on the container. Look it up.

"I take it for brain performance, not just the gym. After reading the Rae et al. study on creatine and cognition I started taking 5g daily. The difference in mental clarity during a bad sleep week is real. And Barebones is the only brand where I can verify what's actually in the tub."

Not just for the gym

For your muscles.
For your brain.
For everyone.

Creatine monohydrate has been studied for 30 years in male athletes. What the supplement industry failed to tell you: it works the same way for women — and it works in your brain, not just your muscles. The research on both has been there for a decade. It just wasn't being talked about.

Women & Strength

"Creatine supplementation in women: a brief review on metabolism and evidence-based outcomes."

Comprehensive review of creatine trials in female populations. Consistent improvements in strength, lean mass, and recovery — with the same safety profile as in men. The "bulking supplement" concern is a myth with no research backing it.

Cognitive Performance

"Oral creatine monohydrate supplementation improves brain performance: a double-blind, placebo-controlled study."

Vegetarians and omnivores supplementing 5g creatine daily showed significant improvements in memory and intelligence test scores. The brain uses phosphocreatine the same way muscles do — for rapid energy when demand spikes.

Bone Health

"Creatine and bone health: a review of the evidence."

Creatine supplementation combined with resistance training has been shown to improve bone mineral density in post-menopausal women — a population the supplement industry almost entirely ignores in their marketing.

Got questions

Everything you
need to know.

Most people notice increased endurance and reduced fatigue within 2–4 weeks of consistent daily use. Strength gains typically become measurable at the 4–6 week mark. Creatine isn't a stimulant — it works by gradually saturating your muscles, so patience and consistency matter more than timing.
Absolutely. Creatine monohydrate is one of the most researched supplements in existence — the data consistently shows it's safe and effective regardless of sex. Concerns about bloating or masculinizing effects are myths. If anything, research shows women may see proportionally larger strength gains than men.
Yes — water, juice, a protein shake, coffee, whatever. It's flavorless and dissolves quickly in any liquid. Because it's micronized (ultra-fine particle size), there's no gritty texture. No need to mix it at a specific time relative to your workout — just take it daily.
No. Loading (20g/day for 5–7 days) reaches saturation faster, but you end up in the same place as just taking 5g/day consistently — it just takes 3–4 weeks instead of 1. We recommend skipping the loading phase: it's unnecessary, can cause GI discomfort, and burns through your supply faster.
Subscribe ($29.99/mo) auto-ships a fresh 100-serving tub every 30 days so you never run out. You can cancel, pause, or skip any time — no fees, no penalty, no runaround. One-time ($49.99) is a single purchase with no strings attached. The subscription saves you $240/year vs. buying one-time every month.
Yes — and this is one of the most underreported findings in sports nutrition. Your brain uses phosphocreatine for rapid energy the same way your muscles do. Multiple double-blind trials have shown creatine supplementation improves short-term memory, processing speed under cognitive load, and mental performance during sleep deprivation. A 2003 study in the Proceedings of the Royal Society found a 17% improvement in working memory with 5g/day. We cite the actual research on our science page — not summaries of summaries.
Honest answer: we're pursuing it. NSF Certified for Sport takes 3–6 months of audits and ongoing compliance costs — it's a process, not a purchase. Ascent and Thorne have it, and we're disclosing that openly because we believe transparency matters more than appearing to have credentials we don't yet hold. In the meantime, every batch is independently tested and the Certificate of Analysis is public. You can verify our purity right now — most certified brands can't offer that same level of real-time transparency.
We offer a full 30-day money-back guarantee — no questions asked, no hoops to jump through. Roughly 5–10% of people are "creatine non-responders" due to genetics. If you're one of them, email us and we'll refund you completely. That's how confident we are in this product.
