What Is Listed

What We Know About The Contents

From the product page. No amounts are published, so our notes are general background, not a dose assessment.

Methylene Blue

Described as supporting mitochondrial function. It is also a pharmaceutical compound with known medication interactions, and its amount here is unknown.

Zinc (Zinc Citrate)

An essential mineral involved in many body processes. Too much zinc over time can cause problems, and the amount here is unknown.

Potassium (Potassium Chloride)

A mineral involved in nerve signalling. It matters for people with kidney conditions or on certain blood pressure medicines.

Purified Water

The liquid base of the formula.

Sodium Benzoate and Potassium Sorbate

Common preservatives. They are synthetic, which sits awkwardly beside the page’s “100% natural” wording.

Amounts

None are published for any ingredient, so nobody can judge whether the dose is meaningful or too much.

Worth noticing: the page’s safety line says the product is generally well tolerated but never mentions methylene blue’s medication interactions. See the full ingredients page and our safety guide.
How It Is Positioned To Work

Before You Order

Our 6-Step Buyer Checklist

1

See a doctor about memory concerns

Forgetfulness can have treatable causes, and a supplement is not a diagnosis.

2

Check medication interactions

Methylene blue interacts with certain medicines, so ask a doctor or pharmacist first.

3

Read the label on your bottle

No amounts are published, so the Supplement Facts panel is the only real answer.

4

Confirm the dose and ramp-up

The source gives drops and mL without a conversion, so follow the label.

5

Check subscription and guarantee terms

A no-autoship badge and an optional subscription both appear, and no refund terms are stated.

6

Skip it if pregnant, nursing or under 18

Ask a doctor first.

Questions

Cognivex FAQ

Cognivex is a liquid dietary supplement, 30 servings per bottle and 1 fl oz (30 mL) on the label, marketed for memory, focus and brain support in adults. It is not a medication and it is not a treatment for memory loss or cognitive decline.

Six ingredients are named: methylene blue, zinc (as zinc citrate), potassium (as potassium chloride), purified water, sodium benzoate and potassium sorbate. No amounts are published, including for methylene blue.

Ask your doctor or pharmacist first. Methylene blue is also a pharmaceutical compound, and it has known interactions, especially with medicines that affect serotonin. The source does not mention this. Never combine it with prescribed medication without advice.

The source says 1 mL once daily diluted in 8 to 10 oz of water, preferably in the morning with a meal, starting with 5 drops and adding 5 drops weekly up to a full dropper. No drops-to-mL conversion is given, so follow your bottle label.

Listed prices are $79 per bottle for 2 ($158), $69 per bottle for 3 ($207) and $49 per bottle for 6 ($294), all with free shipping listed. Confirm everything at checkout.

A 60-day satisfaction promise is advertised, but no refund terms are stated, only that the team will make it right through a contact link. The smallest package does not list it in its bullets. Confirm the terms before ordering.

The page shows a “No Autoship” badge, while its FAQ says there is an optional subscription at checkout. Read the checkout page carefully so you know what you are agreeing to.

No. Nothing here says it prevents, treats or reverses memory loss, cognitive decline or dementia. Ongoing forgetfulness needs a proper medical assessment, not a supplement.

No manufacturer, GMP status or lab report is named. The source lists a street address in Aurora, Colorado, and says it is made in the United States, but gives no company name.

We show none. We could not verify any customer feedback, so we do not reproduce ratings, quotes or photos.

Anyone taking regular medication, especially antidepressants or other serotonin-related medicines, anyone with a medical condition, pregnant or breastfeeding women and anyone under 18.

The Evidence

Scientific References

General background on the listed ingredients, not trials of Cognivex itself. The source offers a reference link but shows no studies, so we link searches instead.

Context: these are searches on topics named by the source; no clinical trial of the finished drops was found. These statements have not been evaluated by the FDA, and the product is not intended to diagnose, treat, cure or prevent any disease.
