Six accounts including the two least flattering, the four complaints that keep coming up, and a short method for reading any supplement review at all.
Five-star reviews on a supplement page tell you almost nothing. They are the easiest to collect, the easiest to write and the easiest to fake. The useful ones are the three- and four-star accounts, because somebody bothered to say what did not happen as well as what did.
We have put six below, including the two least flattering. Individual experiences, not typical results.
The first six weeks were nothing and I nearly stopped. What changed was small: I stopped losing the end of my own sentences. My daughter spotted it before I said anything about it.

That is really the whole review. One capsule, with eggs, done. I am not claiming miracles. I am saying I remembered my grandson's game without the calendar alert and that has not happened in a while.

Warfarin, so the ginkgo line mattered to me. The amount was printed, I photographed the bottle and took it to the counter, and she had no objection after reading it. Buried in a blend, I would never have thought to ask.

Reading is easier in the afternoon, which I did not expect. Names are the same as they ever were. Four stars because it did something, not because it did what I bought it for.

I have thrown away enough half-finished bottles to be sceptical. Being able to send back an opened box is the only reason I tried a three-bottle order instead of one.

Ten weeks and I could not tell you it changed a thing. Refund went through without an argument, which is more than I can say for the last one of these I tried. Three stars for the company, one for the capsule.

This is the most common one and it is not a defect. The ginkgo trial measured at six weeks. The curcumin trial needed eighteen months. Only the theanine pairing acts the same day. Anyone judging this capsule at day ten is judging it before any of the evidence behind it had time to apply.
Also real, and also expected. In every trial cited on this site a meaningful share of participants saw no change. An average across a group is not a forecast for one person, and no page should pretend otherwise.
It is sold through one online checkout and nowhere else. That is deliberate — one price list, one refund process — but it does mean you cannot pick up a bottle and read the panel before buying. The panel is shown at checkout instead, and the ingredient list is on our ingredients page.
Refunds are handled by the official retailer, not by this site, and the steps are shown before you pay. The window is sixty days from delivery and opened bottles are accepted. If you want the exact terms in front of you, they are on the price and guarantee page.
On the word “scam”. People search it before buying anything sold only online, and it is a reasonable instinct. The checks worth doing are these: is the ingredient list published with amounts, is there a refund window that covers opened product, and does the page admit anything at all. This one publishes the label, runs sixty days from delivery, and names two ingredients with no evidence behind them. Make your own judgement from there.
If you want to try it
Opened bottles are accepted, which is the only reason a three-month order is a reasonable first purchase.

Prices, shipping and the refund process are set by the official retailer and confirmed at checkout. Savings are calculated against the $179 single-bottle list price.
They describe individual experiences and are not typical results. Photographs are illustrative and depict models, which is stated in the disclaimer on every page of this site.
Because an average star figure on a page that also sells the product is close to meaningless. The individual accounts, including the three-star one, are more useful.
The ones reported for these ingredients are mild and mostly digestive. The interaction worth taking seriously is ginkgo with blood thinners, covered on the side effects page.
It is a dietary supplement sold through a single online checkout with a sixty-day money-back window covering opened bottles. It is not a treatment for any condition and does not claim to be. Whether the formula is worth the price is a judgement, and the refund window exists so it is a reversible one.
