NeuroNourish (Centrophenoxine) 300mg - DMAE & pCPA, 120 Vegetarian Capsules, 4-Month Supply, Natural Nootropic for Strengthening Memory, Focus, & Cognitive Function, GMP Certified, Made in USA

I'm sorry to say that I couldn't take this product as it gave me migrain headaches. But I think it is a quality product.

Good

Effective

I generally go with Centrophenoxine in powder form. The taste is terrible. With capsules I get what I want without having to suppress the Gag Reflex and drink a couple glasses of water to get rid of the taste. It's also an aid when I travel out of country. A container of white powder draws attention when passing through airport security, a bottle of capsules, not so much.

The short term memory boost I've experienced is fantastic! Centrophenoxine combined with Ancient Nutrition Brain Boost (available only at Sprouts) works amazingly well!

I do like this product, as it does work. The amount of product was not the same as stated on the bottle. Short about 20 capsules.

Didn't see many other brands of this. I ordered it and didn't see any quality issues. It's hard to tell if it works as I take a lot of supplements so it's hard to tell honestly

A study published in 2022 (available on pubmed/ncbi) tested seven Centrophenoxine dietary supplements available in the USA. The testing showed that only one out of seven Centrophenoxine products contains the amount of Centrophenoxine close to what the label claims.Reputable manufacturers (or private label companies) of dietary supplements routinely pay to third party laboratories for unbiased tests of their products. Then the manufacturers/companies receive Certificates of Analysis (CoA) from those laboratories. The CoAs are MEANT to be shown to interested parties outside of the companies. Many companies publish those CoAs on their websites and some even here, on Amazon. I contacted LongiLifeNutri asking them to send me a copy of a Certificate of Analysis from a third-party laboratory for their Centrophenoxine.LongiLifeNutri responded to my request with a statement: 'we are unable to disclose our manufacturing Certificates of Analysis (COA) due to confidentiality reasons, we want to assure you of the effectiveness and quality of our products. We hope we have answered your concern. We will now close this ticket'The real meaning behind the response:1) we either don't test well or the analysis shows that our Centrophenoxine does not contain the proper dose etc., 2) [even worse] we have a low opinion of our consumers' intellectual level, and we think they don't know what exactly a Certificate of Analysis is, so we are going to say it is confidential. We think this is good enough for them
