My Father Taught Me to Challenge Everything, Even About Brain Health After 50
Three real numbers explain why memory shifts in your 50s, and what actually helps.
“And the day came when the risk to remain tight in a bud was more painful than the risk it took to blossom.”
– Anaïs Nin
I think about that quote differently now. For us, the risk isn’t in trying something new. It’s in doing nothing and letting fate take the hand instead.
This weekend was Labor Day, and my husband and I were invited to dear friends’ house in Tampa, right on the bay. What a treat. Beautiful sunrise and sunset over the water. I feel like I’ve relaxed and felt peaceful more than I have in quite a while.
It seems like we all have these stories going on at this stage, sharing what we’re living through with our parents, and how hard the struggle of dementia is, both for the caregivers and for the children. My friend told me some stories about her father, and they sounded so familiar, very much like what we’ve gone through with my mother.
I think that generation just accepted it as fate, not as something preventable. Staying tight in the bud, never asking if it could be different. My father used to say challenge everything, because what seems like a fact today can be disproved by science tomorrow. That’s the risk worth taking, choosing to blossom instead of letting fate decide. That’s part of the huge curiosity that’s driven me forward in this, and I believe we’re making great progress.
Why Your Brain Uses So Much Energy
Here’s a number that reframes the whole conversation. Your brain is about 2 percent of your body weight. It uses roughly 20 percent of your resting energy. A 2002 paper in the Proceedings of the National Academy of Sciences (Raichle and Gusnard) laid this out clearly: the brain’s metabolic rate stays remarkably constant no matter what you’re doing, thinking, resting, or sleeping, because it’s always running expensive background processes.
That energy has to come from somewhere. Every thought, every retrieved memory, every moment of focus draws on the same cellular fuel system that powers the rest of your body. When that system is under strain, and midlife puts real strain on it, the brain feels it first, because it has the least room to spare.
What Is ATP?
ATP (adenosine triphosphate) is the molecule your cells use to store and release energy. Every brain cell relies on a constant, uninterrupted supply of ATP to fire signals, form memories, and stay alert. When ATP production slows or falters, the brain has to work harder for the same output, which is one reason mental fatigue and forgetfulness can feel more pronounced in midlife.
What Creatine Actually Does for Brain Health After 50
Creatine isn’t just a gym supplement. It’s a direct raw material for ATP recycling, and your brain, with its enormous energy demand, depends on the same recycling system your muscles do.
A 2024 systematic review and meta-analysis in Frontiers in Nutrition (Xu et al., 492 participants across 16 randomized controlled trials) found that creatine supplementation significantly improved memory, attention, and processing speed, with a larger benefit in women. I want to be precise here, because precision is the whole point: the same review found no significant improvement in overall cognition or executive function. Creatine supports specific, measurable domains. It doesn’t do everything, and I’d rather tell you exactly what the research shows than round it up. You can read more about the research behind it in Creatine for Women Over 50: 5 Things the Research Shows.
Why Forgetfulness Peaks Between 50 and 54
Here’s the number that stopped me. In a 2022 study published in Women’s Midlife Health (Hayashi et al.), following 12,226 women in the Japan Nurses’ Health Study, complaints of poor memory and forgetfulness peaked at 81.7 percent between ages 50 and 54, then gradually eased after 55. I want to be honest about what this number is and isn’t. This was an occupational cohort of nurses, not a general population sample, and the authors note that limitation themselves. But the pattern, a sharp midlife peak that eases afterward, lines up with what a lot of us describe in our own kitchens and living rooms. You can read more about the word-finding and memory shifts many women describe in Forgetting Words During Menopause: The 3 Real Brain Chemicals Behind It.
This is where citicoline comes in. A 2023 systematic review and meta-analysis in Nutrients (Bonvicini et al.) describes citicoline’s mechanism directly: it increases the intrasynaptic concentration of acetylcholine and supports phospholipid synthesis and neuronal repair. Acetylcholine is the neurotransmitter your brain uses for memory and attention. Citicoline doesn’t force alertness. It supports the raw materials that memory and focus actually run on.
What Is Citicoline?
Citicoline is a naturally occurring compound involved in the production of phosphatidylcholine, a key building block of brain cell membranes, and acetylcholine, the neurotransmitter central to memory and attention. It supports neuronal repair and communication rather than forcing stimulation, which is why it’s studied for memory support rather than energy or alertness on its own.
My Perspective
My father’s line, challenge everything, wasn’t abstract for him. He meant it as a practical instruction: don’t accept a fact just because it’s the accepted one. When I started building Calm Energy, I kept coming back to that. The accepted fact was that midlife forgetfulness is just something you live with. I wasn’t willing to accept that without asking what the actual mechanisms were.
That’s why the formula isn’t built around stimulation. It’s built around the two things this article covers: creatine for the energy system, citicoline for the memory system. Different levers, same underlying question, what does the brain actually need at this stage, not what does the market assume it needs.
I don’t have a tidy ending for the dementia conversations my friends and I keep having. I don’t think anyone does yet. But I’d rather spend my energy on the number I can act on now than accept the one I can’t change later.
Frequently Asked Questions
Why does brain health after 50 change so noticeably?
Your brain uses about 20 percent of your resting energy despite being only 2 percent of your body weight (Raichle and Gusnard, PNAS, 2002). Any shift in how efficiently your cells produce energy shows up first in the brain, because it has the least metabolic room to spare compared to other organs.
Why does forgetfulness peak between ages 50 and 54?
A study of 12,226 women found complaints of poor memory peaked at 81.7 percent in this age range before gradually easing after 55 (Hayashi et al., Women’s Midlife Health, 2022). The exact mechanism isn’t fully mapped, but it lines up with major hormonal and metabolic shifts happening during this window.
Can creatine support brain health after 50?
Research shows creatine supplementation significantly improves memory, attention, and processing speed, with a larger effect in women (Xu et al., Frontiers in Nutrition, 2024). It did not show a significant effect on overall cognition or executive function, so it supports specific functions rather than everything at once.
Is forgetfulness in your 50s the same as dementia?
No. Occasional forgetfulness and word-finding trouble in midlife are common and distinct from dementia, which involves a progressive, significant loss of daily functioning. The research on midlife forgetfulness points to hormonal and metabolic shifts, not a neurodegenerative process.
What is citicoline and how does it support memory?
Citicoline supports the production of acetylcholine, the neurotransmitter central to memory and attention, and supports phospholipid synthesis for neuronal repair (Bonvicini et al., Nutrients, 2023). It works by supporting the brain’s own repair and communication systems, not by forcing stimulation.
Calm Energy is built around these two mechanisms, creatine and citicoline.
