What's Inside
What's Inside
Creatine Monohydrate — 5,000mg per scoop
50 scoops per container · Net Weight: 8.8oz (250g)
Unflavored. No fillers. No caffeine. No stimulants. No artificial anything.
Take 1 scoop (5g) daily — the clinical dose validated in 100+ brain creatine trials. For the enhanced protocol recommended by ISSN women's health research (5–10g/day), take 1.5 scoops (7.5g) daily.
How It Works
How It Works
Your brain stores phosphocreatine as an emergency ATP reserve. Under cognitive load (meetings, decisions, mental multitasking), this reserve depletes. When it depletes faster than it regenerates, brain fog follows.
Women have 70–80% lower creatine stores than men due to lower muscle mass, hormonal differences, and dietary patterns. The result: a brain energy buffer that's depleted before the day is even over.
Daily creatine supplementation raises brain phosphocreatine levels measurably (confirmed by 31P-MRS brain imaging). With a larger reserve, your brain handles cognitive demand without the crash.
Most people notice a difference within 2–4 weeks of daily use.

Your brain is running on less than it should be. Here's exactly why.
Most brain supplements address the wrong mechanism. Creatine addresses the right one — the one backed by 100 clinical trials that nobody aimed at women.
Women have far less brain creatine than men
Women store 70–80% less creatine than men. Your brain uses phosphocreatine as its emergency energy reserve — and yours starts the day depleted.
Your brain consumes 20% of your body's energy
Under cognitive load, your brain burns through its phosphocreatine buffer. Brain fog follows: word-finding failure, working memory gaps, decision fatigue that sleep doesn't fix. That's depletion — and it's the exact state most supplements don't address.
Creatine directly replenishes brain phosphocreatine
A 2024 meta-analysis of 16 RCTs: memory +15%, processing speed +19% vs. placebo. Brain imaging confirms elevated cerebral phosphocreatine. Measurable. Not theoretical.
The science isn't new. Nobody just told women about it.
These aren't marketing claims. They're published, peer-reviewed findings from independent researchers — cited here exactly as they appeared.
Single-dose creatine rescued cognitive performance during sleep deprivation
A single dose before sleep deprivation improved memory and processing speed vs. placebo. Brain imaging confirmed elevated cerebral phosphocreatine. Effects lasted up to 9 hours.
↑ Memory & Processing Speed · Same-Day EffectThe largest review of creatine and cognition confirms it works
16 RCTs analyzed. Creatine improved memory by 15% and processing speed by 19% vs. placebo. Effects were largest in women and older adults.
+15% Memory · +19% Processing Speed · 16 RCTsFirst RCT specifically in perimenopausal women shows improved cognitive function
The first RCT in perimenopausal women: improved reaction time, elevated brain phosphocreatine, reduced cognitive symptoms of hormonal transition.
Perimenopausal Women · Brain PCr ↑ · Reaction Time ↓The sharpest version of you
doesn't appear overnight.
Creatine builds a reservoir — not a spike. Here's what the research shows, week by week. We'd rather set your expectations honestly than oversell and lose you at week one.
Loading phase
Brain creatine is saturating. You may notice little. That's expected — the reservoir is still filling.
First shift
Most women report the first noticeable change here — clarity under pressure, less afternoon crash, faster word recall.
New baseline
The shift becomes consistent. Less day-to-day variability. This is no longer a good day — it's your new normal.
Full effect
Women who reach this stage describe it as feeling like the earlier version of themselves. The sharp version. That's why we give you 90 days.
When the sharpest version shows up
You haven't failed at supplements.
You've been using the wrong ones.
Most brain supplements target the wrong mechanism. Here's why creatine is categorically different from everything you've tried.

| Addresses brain phosphocreatine | ✓ | — | — | — |

Lion's Mane, Ashwagandha, and caffeine don't address brain phosphocreatine, the specific mechanism behind your brain fog.
Common Questions
Is creatine just for bodybuilders?
Is creatine just for bodybuilders?
Not anymore. Creatine was marketed to gyms for decades, but the cognitive research was there the whole time. A 2024 meta-analysis of 16 RCTs, a 2024 Nature study, and a 2025 clinical trial specifically in women all confirm it. The gym industry found it first. The brain science was always underneath it.
Will I gain weight or get bulky?
Will I gain weight or get bulky?
No. At 5g/day, water retention is minimal and intracellular (inside muscle cells, not subcutaneous). Women in clinical trials at this dose reported no meaningful change in body composition.
I've tried brain supplements before and they didn't work.
I've tried brain supplements before and they didn't work.
They were addressing the wrong mechanism. Lion's Mane targets nerve growth. Ashwagandha targets cortisol. Neither addresses brain phosphocreatine, the energy substrate that depletes under cognitive load. You weren't buying bad products. You were buying solutions that don't target your actual problem.
How long until I notice a difference?
How long until I notice a difference?
Brain creatine saturation takes 2–4 weeks. Most women notice something by week 2–3. Full cognitive benefit builds over 2–3 months, which is why we offer 90 days. Take it daily, with or without food, same time each day.
Is this safe to take with birth control or HRT?
Is this safe to take with birth control or HRT?
No known interactions with hormonal contraceptives or HRT. Over 100 clinical trials, 30+ years of research. Consult your physician if you have a specific medical condition. Not recommended during pregnancy.
What makes Lucida different from other creatine products?
What makes Lucida different from other creatine products?
Three things: formulated specifically for women's cognitive performance, the clinical 5,000mg dose backed by 100+ trials, and a 90-day money-back guarantee. Most creatine products are built for the gym. This one is built for your brain.
Why is there only one ingredient?
Why is there only one ingredient?
The research is on creatine monohydrate, not a blend that obscures what's working. One ingredient. Best evidence. You can't build a stack on a shaky base.
What if it doesn't work for me?
