The Science

Built on the research.

TheScience

Over a thousand peer-reviewed creatine studies. Decades of documented research. What was missing wasn’t the science — it was a product that felt as thoughtful as the women choosing it.

More than a  muscle supplement.

Your brain runs on ATP. Creatine helps replenish it — supporting the neurons involved in memory, focus, and decision-making.*

Emerging research suggests it may support cognitive function, especially memory and processing speed.Not a stimulant. Not a shortcut. A fuel source your brain already uses.*

Arrival is built around  the full picture.

Creatine is one of the most researched supplements in existence. Over a thousand peer-reviewed studies. The category just never bothered to tell women the full story.

Bones + Strength

Bone health is built over decades.Resistance training is one of the clearest tools for supporting it, and creatine is well studied for strength alongside it.*

Energy + Mood

No stimulants. No crash.
Creatine replenishes ATP, the energy your cells run on ,with emerging research exploring its role in mental fatigue, stress, and mood under demanding conditions.*

Brain + Cognition

The brain accounts for roughly 20% of the body’s energy use. That energy runs on ATP — and creatine helps regenerate it.

In women, this becomes more interesting because hormonal changes may influence creatine synthesis, transport, and turnover across life stages, from the menstrual cycle through menopause. That is part of why creatine is being discussed more seriously in women’s health, with emerging research suggesting support for memory, attention, and processing speed. *

Bones, Strength + Recovery

Bone mass peaks around age 30 and begins a gradual decline over time, with bone loss accelerating around the menopause transition. Research suggests up to 20% of bone loss can occur during these stages.

Paired with resistance training, creatine helps support ATP regeneration during effort, the force your muscles can produce, and the consistency of training over time. In older women, the strongest evidence shows meaningful strength gains, especially in longer-term resistance training programs.

It has also been studied alongside resistance training for healthy aging and bone health, with one 12-month clinical trial in postmenopausal women showing preserved bone density. Emerging evidence suggests it may also support recovery between sessions by helping maintain muscle function after hard training. * The earlier you build strength, the more you have to protect.

Mood + Energy

Not all fatigue is physical. Mental energy depends on the same cellular fuel systems as everything else — and creatine helps support them.

Emerging research suggests creatine may help reduce mental fatigue in demanding conditions, and some studies have found a positive effect on mood state when the brain is under heavier stress, like sleep loss. *

Supplementing doesn’t manufacture energy, it helps support the raw material your cells already rely on.

Why women's creatine deficit changes everything.

Arrival was built around that gap —
not as a marketing angle, but as a design brief.

Women tend to have significantly lower endogenous creatine stores than men — a difference often cited in the research at roughly 70–80% lower. That is not a trivial distinction. It helps explain why creatine has become a more relevant conversation in women’s health, especially across energy, cognition, training, and healthy aging.

There are a few reasons that gap matters.
We start with less in reserve.

About 95% of the body’s creatine is stored in skeletal muscle, and women generally carry less muscle mass to store it. On top of that, many women consume less dietary creatine than men, especially if they do not eat red meat regularly.

Hormones appear to influence the system.

Recent reviews suggest hormonal changes across the menstrual cycle, pregnancy, and menopause may influence creatine synthesis, transport, and creatine kinase activity. That makes creatine metabolism more dynamic across a woman’s life than the category has typically acknowledged.

The research was there. The category lagged behind.

Research on creatine in women has expanded across strength, cognition, healthy aging, and menopause-related transitions. But for years, most of the category kept presenting the same product in the same language to the same imagined customer.

Creatine Monohydrate

Creatine monohydrate is the form used in the vast majority of creatine research. It’s the most studied, most established form — and other forms have not consistently shown better uptake, retention, or performance outcomes. We didn’t try to reinvent the ingredient. We chose the form the research keeps coming back to.

Organic Blueberry

Organic Blueberry Powder Real fruit. Not "natural flavor" — a term that can legally mean almost anything, and usually does. Organic blueberry powder is exactly what it says it is: whole blueberries, dried and milled, with nothing added and nothing stripped out. 

 It earns its place in the jar twice over. First, for flavor — mild, clean, and natural enough to disappear into whatever you mix it with rather than competing with it. Second, for what comes with real fruit: blueberries are naturally rich in anthocyanins and polyphenols. In a product built around brain and body performance, that’s not a coincidence. It’s a decision.

This is what clean  actually looks like.

A product chosen with the same care and intention that goes into everything else that matters. Not the absence of doubt — the presence of something better.
