What is Cognivex?

A daily memory and focus support supplement

Cognivex combines methylene blue with zinc and potassium in a liquid taken once a day, usually diluted in a glass of water.

It is a dietary supplement, not a drug, and it is meant to complement sleep, nutrition, movement and regular checkups. Amounts are not published on the seller’s page, so check the label on your bottle.

Important: methylene blue can interact with antidepressants and other serotonin-affecting medicines and is unsuitable for people with G6PD deficiency. Ask a healthcare professional before use. See our references.

FAQ

Frequently asked questions

What is Cognivex?

Cognivex is a liquid drops dietary supplement in a 1 fl oz (30 mL) bottle, positioned to support memory, focus and mental clarity alongside sleep, nutrition and activity.

How do I take it?

Cognivex is taken in drops, usually diluted in a glass of water once a day. Serving sizes differ between sellers, so follow the directions printed on your bottle and never exceed the label serving.

What are the ingredients?

The seller names methylene blue, zinc and potassium, without amounts. Check the Supplement Facts panel on your bottle.

Is it safe with my medications?

No, not always. Methylene blue can interact with antidepressants and other medicines that affect serotonin (SSRIs, SNRIs, tricyclics, MAOIs). Check with a physician first, especially if you take any prescription medication.

Who should not use it?

People with G6PD deficiency, anyone pregnant or nursing, and anyone under 18 should not use it. Ask a healthcare professional if you have any medical condition.

Will it improve my memory?

No supplement can promise that. Cognivex is a dietary supplement meant to complement sleep, nutrition, activity and a healthy lifestyle, and it is not a treatment for memory loss or any condition.

What's the guarantee?

Orders are covered by a 60-day money-back guarantee, subject to the return terms shown at checkout. See our refund policy for details.
