Brain Health Supplement Review
Pineal Guardian X is a liquid sold by Nutraville as a "brain detox formula" that "flushes toxic fluoride" from the pineal gland. Its sales pages go much further than most: they say the formula can help with "reversing memory loss and early stages of Alzheimer's disease" and tell the story of a woman who "permanently reversed her Alzheimer's". The label shows 11 ingredients, including lion's mane, bacopa and ginkgo, sharing a 1,202 mg blend per serving with no individual doses. No supplement has been shown to reverse Alzheimer's disease.

Our Assessment
The most serious problem is the marketing. The homepage FAQ talks about "reversing memory loss and early stages of Alzheimer's disease" and says tamarind "helps prevent Alzheimer's-related neurodegeneration". The text sales letter, narrated by a "Mark Thompson", describes his wife Christine, who "permanently reversed her Alzheimer's" with a formula from "a very reclusive doctor named Dr. Harrison", who is never fully named. No supplement has been shown to reverse or prevent Alzheimer's disease, and people with memory problems need a medical assessment, because some causes are treatable.
The letter also builds its story on fluoride, citing "Harvard Medical School" and a "Dr. Philippe Granjean", an apparent misspelling of Philippe Grandjean, a real Harvard environmental health researcher who has studied fluoride. We found no indication that he has any connection to the product. The page also shows a stock image stamped "FDA APPROVED"; the FDA does not approve dietary supplements.
The label is more modest. Each 2 mL serving has a "Proprietary 1:8 Extract Blend" of 1,202 mg: lion's mane, lemon juice powder, tamarind, bacopa, moringa, chlorella, ginkgo, maritime pine bark, spirulina, neem and boron. Some of these have small trials for memory or attention, but the doses are not disclosed, and even if the whole blend were lion's mane it would be less than half the 3 g a day used in the main trial.

Overview
Pineal Guardian X is sold by Nutraville through thepinealguardian.com, with ClickBank as the retailer, and on Nutraville's own store and Amazon storefront. The domain was registered in April 2024; its registration record lists a Singapore company. Returns go to 285 Northeast Ave in Tallmadge, Ohio, the same address several other supplements we review use.
The homepage calls it a "Brand New Brain Detox Formula Designed To Restore Your Memory and Cognitive Function" that "flushes toxic fluoride and restores natural melatonin production in your brain", and the store calls it "Rapid Pineal Gland Decalcification Drops". Calcification of the pineal gland is common with age and is not an established cause of memory loss, and no study shows a supplement removes it.
The same brand sells JointVive X for joint pain. Its label lists the same eleven ingredients in the same 1,202 mg "Proprietary 1:8 Extract Blend", so one formula is marketed both as a brain detox and as a joint remedy.

Pricing & Value
On October 4, 2026, the ClickBank homepage offered 1 bottle for $69, 3 for $177 and 6 for $234, with $9.99 shipping on the smaller packages; the text sales letter offered 2, 4 or 6 bottles instead. Nutraville's own store listed the same product at $49, $39 and $29 per bottle for 1, 3 and 6 bottles, about a quarter to a third cheaper.
The sales page promises a refund within 365 days, "even empty bottles", less shipping and handling. The shipping page says returned items "must be unused and unopened". If you order, get the terms confirmed in writing.
Safety & Buyer Notes
Memory loss can come from treatable causes, including vitamin B12 deficiency, thyroid problems, depression, medication side effects and sleep apnea. A product that promises to reverse Alzheimer's can delay the assessment that finds them. If you or someone close to you is losing memory, see a doctor.
Ginkgo can increase bleeding risk with blood thinners such as warfarin, according to NIH's NCCIH. Bacopa can cause digestive upset and may interact with thyroid medication, and neem is not advised in pregnancy. With no doses disclosed, the risks cannot be weighed.
What Real Users Say
We looked for independent feedback on October 4, 2026.
There is no Trustpilot profile for thepinealguardian.com. Two profiles for affiliate websites promoting the product have been removed by Trustpilot. Nutraville, the brand, has a claimed profile with 75 reviews and a TrustScore of 4.4, but the recent reviews we read were about service and delivery, not about Pineal Guardian X.
ScamAdviser shows a trust score of 0 for thepinealguardian.com while also labelling it "Likely Safe", based on a scan five months old. We do not give this much weight either way.
Many search results are PDF files uploaded to university and municipal websites and paid press releases. They are marketing, not independent reviews.
Our read: There is no independent evidence that Pineal Guardian X improves memory, and none that it affects Alzheimer's disease.

FAQ
No. No supplement has been shown to reverse or prevent Alzheimer's disease, and there is no study of Pineal Guardian X. If you or someone you care for is losing memory, see a doctor; some causes are treatable.
Pineal calcification is common with age, but it is not an established cause of memory loss, and no study shows that a supplement removes it or improves memory by doing so.
According to the label on nutraville.com: a 1,202 mg blend per 2 mL of lion's mane, lemon juice powder, tamarind, bacopa, moringa, chlorella, ginkgo, maritime pine bark, spirulina, neem and boron, with no individual doses.
No. The FDA does not approve dietary supplements, although the sales letter shows a stamp reading "FDA APPROVED". Its own footer says its statements have not been evaluated by the FDA.
On October 4, 2026, Nutraville's own store listed it at $49, $39 and $29 per bottle for 1, 3 and 6 bottles, compared with $69, $59 and $39 on the ClickBank pages.
Bottom Line
Pineal Guardian X contains some ingredients with modest research for memory, at doses its label does not reveal, and sells them with claims about reversing Alzheimer's that no supplement can support.
If memory is a concern, start with a doctor. If you want to try lion's mane or bacopa, buy them on their own so you know the dose, and keep expectations modest.
