The Science
4 Numbers Every Woman Over 40 Should See
Creatine is the most studied supplement in history. Here's what it says about women.
70โ80%
Less creatine stored in women vs. men โ drops further after 40
1โ2%
Muscle mass lost per year after 50 as oestrogen declines
16.4%
Brain creatine increase after 8 weeks supplementation
685
Clinical trials โ no significant side effects vs. placebo
The Research
The Exact Things We Lose After 40 Are the Exact Things Creatine Restores
This isn't a coincidence. Here's what the clinical research shows โ specifically in women.
Benefit 1
Protect & Rebuild Muscle
+5.8%
Lean muscle gain vs. 3.7% placebo over 10 weeks
+15%
Performance improvement in women (vs. 6% in men)
After 40, women lose muscle at an accelerating rate โ and muscle is what keeps you strong, metabolically healthy, and independent. Creatine replenishes ATP, giving your muscles the fuel to build and maintain tissue your body is otherwise shedding.
Vandenberghe et al., J Appl Physiol 1997
Benefit 2
Lift the Fog. Stabilise Your Mood.
+16.4%
Increase in frontal brain creatine in women going through hormonal changes
โ Mood
Strong evidence for improved mood and reduced depression in women
The frontal lobe โ where memory, focus, and emotional regulation live โ is the part of the brain most affected by hormonal shifts after 40. Supplementation helps restore the energy your brain needs to think clearly and feel like yourself again.
Smith-Ryan et al., Nutrients 2021
Benefit 3
Get Your Energy Back. Recover Like You Used To.
โ Fatigue
Reduces mental and physical fatigue under stress or sleep deprivation
+20โ40%
Increase in muscle creatine stores with daily supplementation
The bone-deep tiredness. The two-day soreness after a workout that used to be easy. Creatine speeds up ATP recycling โ the process that determines how quickly your body recovers. When you restore your stores, recovery feels like it did ten years ago.

Why Senora
What You're Losing Is What This Restores
Lift the Fog
+16.4% brain creatine in 8 weeks
The frontal lobe โ memory, focus, mood โ has the lowest creatine in women. Supplementation restores brain energy.
Smith-Ryan et al., Nutrients 2021
Protect Your Muscle
+5.8% lean muscle vs. 3.7% placebo
You lose 1โ2% muscle per year after 40. Creatine gives muscles the ATP to maintain what your body is shedding.
Vandenberghe et al., J Appl Physiol
Strengthen Bones
1.2% loss with creatine vs. ~4% without
1 in 2 women will fracture from osteoporosis. Creatine supports osteoblasts โ especially with resistance training.
Chilibeck et al. โ 12-month RCT
Get Energy Back
Women: 15% improvement vs. 6% in men
The exhaustion coffee can't fix is a cellular energy deficit. Creatine regenerates ATP โ for stairs, alertness, everything.
Zooki Research Review, 2025
Stabilise Mood
Strong evidence for improved mood in women
Creatine is involved in neurotransmitter pathways for mood, focus, and emotional resilience.
Smith-Ryan et al., 2021
Cellular Hydration
Electrolytes are co-factors for creatine uptake
Without sodium, potassium, magnesium โ creatine sits in your gut. Senora combines both for full absorption.

The Loading Phase
Creatine accumulates in muscle and brain cells. Electrolytes help hydration almost immediately. Don't skip days.
Days 7โ21
Energy Shifts First
2pm crash softens. Recovery improves. Brain fog starts lifting. Word recall and motivation return.
Days 21โ60
Strength You Can See
Measurable lean muscle, better performance, improved body composition. Daily tasks feel easier.
Day 60+

Benefits compound. Muscle stores stabilise. Bone density builds over months. This is maintenance mode.
What's Inside
Clinical Doses, Not Fairy Dust
Every ingredient at the dose the research used. No blends. No filler.
| Ingredient | Why It's Here | Dose |
|---|---|---|
Creatine Monohydrate | Supports muscle, brain energy, bone density. 685 trials. | 5,000 mg |
Sodium Sea Salt | Drives creatine into cells. Fluid balance and nerve function. | 1,000 mg |
Potassium Potassium Chloride | Heart, muscle, blood pressure. Counterbalances sodium. | 200 mg |
Magnesium Magnesium Malate | Sleep, mood, bone density. 300+ enzymatic reactions. | 66 mg |
The Invisible Decline
After 40, Your Body Needs What It's Losing
Oestrogen drives creatine production, electrolyte balance, bone density, and brain fuel. When it declines, everything downstream is affected โ and most women are never told what to do about it.
Oestrogen DeclinesโLess creatine produced
Night SweatsโElectrolytes depleted
Muscle FallsโLess creatine stored
Brain Energy DropsโFog, fatigue, mood
Common Questions
Straight Answers.
Won't creatine make me bulky?+
No. It draws water into muscle cells, not under skin. You may see 1โ3 lbs initially โ that's it working. Most women notice clothes fit better, not worse. You don't have the hormonal profile to bulk up.
Isn't creatine just for gym bros?+
Your brain uses 20% of your energy, and creatine is critical for brain ATP. Women store 70โ80% less than men โ you have more to gain from supplementation.
How long until results?+
Hydration: 1โ2 weeks. Cognitive clarity: weeks 4โ6. Muscle and bone: builds over months with consistency.
Safe with medications?+
685 trials, no greater adverse effects than placebo. Always consult your provider, especially with kidney concerns.
Why add electrolytes?+
Creatine uptake depends on sodium, chloride, calcium. Without electrolytes, creatine can't enter cells efficiently. Hormonal changes after 40 deplete them faster too.
Safe during hormonal changes?+
Yes. Both are naturally occurring. Research suggests creatine may be particularly beneficial during this stage โ supporting muscle, brain, and bone health as hormones shift.
