The question I get constantly is about how many days of memory tracking it takes before you trust a supplement more than your own optimism. I get some version of that question constantly about this whole brain health audit, and I still don't have a clean one-line answer for it, which is probably why I ended up building a spreadsheet instead of just trusting my gut.
Quick housekeeping before any of the numbers: this piece contains affiliate links, and buying through one earns me a small commission at no extra cost to you. Every product mentioned here is something I actually bought, actually tracked, and actually logged into a spreadsheet with more tabs than my old firm's year-end binder ever had. Thirty years of reconciling other people's books does not make me a doctor, so treat everything below as one retired accountant's personal audit, not medical advice, and check with an actual physician before changing your own routine.
Why Ninety Days, and Why a Spreadsheet at All?
Ninety days is a fiscal quarter, and thinking in quarters is about the only instinct thirty years of accounting left me with that still feels useful some mornings.
The moment that actually pushed me toward tracking this properly wasn't dramatic. It was catching myself four pages into a new novel, still flipping back to check which brother was which from page one, as if the book had quietly reset itself when I wasn't looking. That's not a crisis. That's just irritating enough to make a numbers guy start a new tab.
Before this ninety-day stretch, there was an earlier scare. I've told the story behind my cognitive audit in full elsewhere. This time felt different: less panic, more of a slow leak I wanted documented properly instead of just worried about.
So I built a brain health audit the only way a numbers person knows how to build anything: daily, numbered, slightly obsessive.
Four inputs went into the sheet every single morning — hours slept, a subjective clarity score out of ten, a timed word-retrieval check, and whatever I'd spent on supplements that day. Most mornings, the first real motion of the day is just my fingers finding the keys to log that clarity score before the coffee's even finished doing its job — small, mechanical, oddly grounding. Three hundred and sixty entries by the end of it, across a full quarter of memory tracking. My wife likes to point out this spreadsheet now has more tabs than our actual tax returns, which is not a compliment, though it's not wrong either.
The Placebo Problem Nobody Likes Talking About
Readers email me some version of the same uncomfortable question almost every week: how do you know any of this is the product and not just you, ninety days deep into finally paying attention to your own brain? Honestly, I don't know with total certainty.
Nobody fully does.
There's a whole separate audit where I try to isolate exactly how much of a clarity-score bump is genuine product effect versus simple attention effect, and that piece does the heavy lifting on that particular question — this one doesn't need to repeat it. What I can say here is that I ran the same daily test for two full weeks before adding anything new, so the starting number was a real baseline and not a guess pulled from memory.
The Supplement ROI Math Behind the $54 Price Tag
Total spend across the full ninety days landed around one hundred and sixty dollars, which works out to roughly thirty-five dollars for every point my clarity score gained by the end of the audit.
My starting score was a 3.2 out of 10. It closed the quarter at 7.8.
I've broken down the full brain supplement ROI math in more detail elsewhere, tab by tab, so I won't re-run every formula in this piece. The short version: watching a number climb that much for less than the cost of a mid-tier streaming bundle is a better return than anything my old 401(k) produced over the same stretch.
Testing The Brain Song: What Fifty-Four Dollars Bought Me
The one new variable I actually added partway through this audit was The Brain Song, an audio-based program that runs around fifty-four dollars a month — less than what my wife and I used to spend on a decent lunch out.
No capsules. No new bottle crowding the shelf. Just headphones and a track, which appealed to the part of me that has never loved adding another pill to the rotation.
Sound doing something measurable to a brain that spent three decades staring at accountancy ledgers felt like a stretch to my inner auditor, and I logged the first couple of entries expecting nothing. A spreadsheet doesn't care what you believe going in, though — it just wants the number.
Weighing the Alternatives
Other line items got considered before I committed to just one. The Genius Song sits at a nearly identical price, and part of me wanted to run both side by side.
Changing two variables in the same quarter felt like the kind of accounting shortcut that gets an audit rejected, though — you don't switch your depreciation method mid-year without an asterisk the size of Texas, and a supplement test isn't any different.
Curiosity about the actual return on investment of a cheaper option kept me from jumping straight to NeuroPrime, which sits well above what I was ready to commit before proving out something less expensive first.
The full side-by-side math against a similar premium option lives in my Neuro-Thrive vs. NeuroPrime comparison, tab for tab, for anyone who wants to see how that particular audit shook out.
Eight Weeks Without Afternoon Coffee Taught Me Nothing Useful
Every honest audit needs a loss column, so here's mine. Earlier in my testing, I cut afternoon coffee out completely for eight straight weeks, on a theory that the 2:30 crash was really caffeine withdrawal wearing a brain-fog costume.
My clarity scores during that stretch didn't move in any direction worth reporting. Same mediocre range, just without the coffee.
There's a separate audit built entirely around that particular afternoon slump, and it goes deeper into the pattern than this piece needs to. For this one, the takeaway is simple: cutting coffee wasn't the fix for me, whatever it does for somebody else's chemistry.
How Do You Read a Supplement Label Without Getting Fooled?
A forum contact of mine, a former pharmacist named Mireille Chatham who tracks her own protocols with the same stubbornness I bring to a spreadsheet, is the one who taught me to actually pull a product's third-party test certificate instead of trusting the front-of-bottle claims.
There's a full piece where I walk through the exact point I stopped trusting brain supplement labels at face value, so I'll keep this part short: the ingredient list printed on the box and the dose that actually shows up in an independent lab report are not always describing the same product, and that gap matters more than any headline claim on the packaging.
Should You Try This, and When Should You Walk Away?
My old client turned genuine friend, Clifford Achebe, spent his career running a medical supply distribution business, and he still asks me pointed, liability-and-evidence questions about literally everything I test — out of habit more than suspicion at this point.
Track it, prove it, or don't tell people it worked — that's more or less the whole approach, borrowed straight from thirty years of client meetings.
Anyone chasing the exact word-retrieval drills I use to check verbal recall day to day will find that broken out in its own piece, along with the full month-by-month tab structure behind this entire audit — each month gets its own tab, with a rollup summary at the end, which is a separate writeup from what this one covers.
My answer to "should you try this" is the same answer I'd give a client asking whether to keep an underperforming vendor: set a real, defined test window, track it daily instead of vaguely, and cut the loss if the numbers haven't moved by the end of it. For me, The Brain Song earned its spot in the assets column over these ninety days — clarity score closed at 7.8, up from 3.2, with a noticeably faster morning retrieval time to go with it. I'm still fifty-five. I'm still going to blank on somebody's name at some dinner party eventually. The ledger, for once, is actually in the black, and you're welcome to look at The Brain Song here yourself if you want to run your own version of this audit.
