On this page
This page exists because there are five things we would want to know before ordering, and none of them appear in the marketing. We would rather you order with them in front of you than discover them afterwards and feel misled. If any of the five is a dealbreaker for you, that is a legitimate outcome of reading this.
One: the St. John’s Wort problem
This is the biggest thing on the page and it is a safety point, not a marketing quibble. St. John’s Wort induces the CYP3A4 enzyme and the P-glycoprotein transporter, which means it makes your body clear a long list of medicines faster and lowers their effectiveness. Documented consequences in the published literature include contraceptive failure and transplant rejection. It also raises serotonin syndrome risk alongside SSRIs, SNRIs, triptans and tramadol. If you take any prescription medicine, including hormonal contraception, do not start this without a pharmacist check. That check is free and takes five minutes.
Two and three: the refund window and the bundle mismatch
The guarantee is stated as 60 days, and marketing for this product has also described six months risk-free in the same FAQ. Those cannot both be true, so get the correct figure in writing before ordering. Separately, a three-bottle order is a 90-day supply and a six-bottle order is 180 days - both outlast a 60-day window. The bundle pricing is genuinely cheaper per bottle, $49 against $69, but you are paying for that discount by committing beyond the period in which you can change your mind. Set a calendar reminder for day 50 from purchase.

See Cognizil PricingFour and five: dosages and testing
Per-serving milligram amounts are not published for any of the six ingredients, and extract standardisation is not stated for the botanicals. That means you cannot check any amount against the research, you cannot compare cost per milligram against a competitor, and with Huperzine-A and St. John’s Wort specifically you cannot make an informed safety judgement. There is also no published batch certificate of analysis. FDA facility registration and GMP compliance are both legal baselines rather than quality credentials - neither means anyone independent has tested the finished product.

Pricing and packages
All pricing below is from the Cognizil official website. The Cognizil discount is applied automatically by quantity — there is no code to enter, and quantity tiers are the only genuine saving available.
| Package | Price per bottle | Total | Supply | Shipping |
|---|---|---|---|---|
| 1 bottle | $69 | $69 | 30 days | Charged |
| 3 bottles | $59 | $177 | 90 days | Charged |
| 6 bottles — best value | $49 | $294 | 180 days | Free (US) |
All tiers carry the money-back guarantee. Note that marketing for this product has described the window as both 60 days and six months — confirm which is correct, and whether it runs from purchase or delivery, with support before ordering. See our refund policy.
Verdict
Get a pharmacist check first, and treat that as non-negotiable rather than cautious. Then buy one bottle rather than a bundle, because the bundle discount commits you past the guarantee and the dosages are undisclosed.
Who this is for
Cautious buyers who want the drawbacks laid out before ordering. Start with one bottle, and get the pharmacist check done first.
If you are still deciding, read our buyer’s checklist and our refund policy review before ordering, and check the full ingredient list against anything you currently take.
