What Shoppers Say About Prevagen
Created with AI, based on recent reviews
Prevagen receives overwhelmingly negative feedback from shoppers, who cite excessive pricing, lack of noticeable results, and concerns about product safety and misleading marketing claims. The vast majority of reviewers report seeing no improvement in memory, focus, or alertness after taking the supplement, with some reporting adverse effects like hair loss. Several reviewers question the validity of the company's research and note that independent verification of effectiveness is lacking, comparing the product unfavorably to simple, inexpensive dietary alternatives.
A small minority of reviewers report positive experiences, with one shopper noting that their husband experienced noticeable memory improvement after consistent use over several years and observed a decline in cognitive function when skipping doses. However, this isolated positive account is vastly outnumbered by complaints about wasted money, unsubstantiated claims, and the product's premium cost relative to perceived benefits.

Complete waste of product and the price tag is ridiculous. You'd honestly get better results tying a knot in a string and calling it a day.

Save yourself the money on this one. Medical experts at Mayo have stated that it's probably going to cause more problems than it solves. A simple carrot every day is going to do way more for you and won't drain your wallet nearly as fast.

I tried this product a few months back, took one tablet every day for about a month and stopped. Then in early July I started using it once more. Within a couple of weeks, I noticed something alarming while brushing my hair in the morning - I'd pull out a significant amount of hair each time. It clicked then that this exact thing had happened before when I was taking this supplement, but I hadn't put two and two together at that time. The moment I quit taking it, the hair shedding completely stopped. To make matters worse, at my last salon appointment, my stylist commented that my hair felt incredibly dry, drier than she'd ever encountered. Once again, the only variable that changed was this supplement since I haven't switched my hair care routine. I have an unopened bottle sitting here, but there's no way I'm going to take it again.

My husband struggled with memory issues for years. He's been taking this for a couple years now and while he still forgets things from time to time, his overall memory has gotten noticeably better. If he skips it for a couple days, we can tell right away because he gets forgetful again. It's definitely pricey, but for us the improvement we've seen makes it worth the cost.

AARP doesn't back this product and they've called out the misleading marketing tactics. There aren't any independent studies proving anything - all the research was done internally by the company itself. Plus the cost is outrageous for something with no real proof behind the marketing! Word on the street is that the founder's mother came up with the jellyfish ingredient concept, but the son took it and ran, even getting a court order to keep his parents away. He wouldn't even do an on-the-record interview about it!

Not worth the price tag. My husband and I have both been using this and we haven't noticed even one improvement. We're not any sharper, our focus hasn't gotten better, we're not more alert. Absolutely nothing to show for it. Complete waste of both time and money.

This is expensive stuff that doesn't deliver. My wife and I both took it for half a year. We're both over 70 and honestly couldn't tell any difference in how our brains or bodies felt. Started feeling like we were popping those fake smart pills, you know the ones filled with nonsense. And the best part? When you finally realize what you've been taking is garbage, they tell you that means it's working!
