It's Not Dementia You're not losing your mind. Your cells are losing fuel. And that part you can actually fix.

If your brain fog has made you feel like something is wrong with you specifically, it hasn't. Over 60% of women going through perimenopause report cognitive changes.1 That's not a fringe experience. That's the majority.

The problem is that most women are told one of three things: "you're too young for menopause," "there's nothing wrong with you," or "it's just stress." None of these are helpful, and none of them are accurate. The dismissal itself becomes a second injury. You start doubting your own experience.

The research is clear: perimenopause-related cognitive changes are real, measurable, and physiological.5 They show up on neuroimaging. They correlate with hormonal fluctuations. They are not "in your head." They are in your biology.

Your brain is one of the most energy-hungry organs in your body. It runs on a molecule called NAD+, which acts as cellular fuel. NAD+ declines naturally with age in everyone, but in women going through perimenopause, that decline is steeper and faster.2,6

Why? Because estrogen is a natural antioxidant.7,8 It supports the systems that produce and protect NAD+. As estrogen levels fluctuate and drop during perimenopause, two things happen at once:

This is why perimenopause can feel so metabolically brutal. It's not just about hormones. It's about what the hormone shift does to your cells' energy supply.

Most supplements address one half of this. Your NAD+ isn't just declining because you're making less of it — there's also an enzyme called CD38 that rises with age and inflammation and actively burns through your NAD+ supply.9,10

NMN and NR — the supplements you've probably heard most about — both work on the supply side. They give your body raw materials to manufacture more NAD+. That matters. But during perimenopause, the supply problem is only half the story. The demand side — CD38 actively burning through what you make — is the half they don't touch.

During perimenopause, inflammation tends to increase (partly because estrogen's anti-inflammatory protection is dropping). That means CD38 activity spikes. So you're being hit from both sides:

This is why taking NMN or NR and feeling underwhelmed is so common. You're increasing supply into a system that's draining faster than before. The bucket is still leaking.

NMN and NR are the most widely sold NAD+ supplements, and for good reason — they do work. They're precursors: raw building blocks your body uses to manufacture NAD+. If your only problem were that you weren't making enough, they'd be the right answer. But perimenopause adds the CD38 problem to the mix. You're not just producing less; you're draining faster. Feeding the supply without addressing the drain is a partial fix at best.

NAD+ IVs take the supply approach even further: they deliver NAD+ directly into your bloodstream, bypassing the manufacturing step entirely. The effect is real and immediate. It's also expensive, clinic-dependent, and gone by the next day. You're borrowing NAD+ for an afternoon rather than restoring your own capacity to hold it.

The real question isn't "how do I add more NAD+?" It's "why am I losing it, and how do I fix that?"

There are three levers on your NAD+ economy: production (make more), recycling (reuse what you have), and demand (stop burning through it so fast). Precursors and IVs pull only the first lever. A complete system needs to pull all three.

That's exactly what NAD Regen was designed to do. Not a precursor. Not a single ingredient. A system that helps your body produce, recycle, and protect its own NAD+. Every day, no needle, no clinic. The most common thing women say? "I didn't realise how foggy I'd been until the fog started lifting."
