Does Prevagen Really Work?

Why did the makers of Prevagen settle a class action lawsuit in 2020 with the FTC over deceptive business practices and false advertising?

A couple of weeks ago, I released a video on a controversial Alzheimer’s drug that used the same scam: Controversy Around FDA’s Approval of Biogen Alzheimer’s Drug, Aducanumab (https://nutritionfacts.org/video/aducanumab-for-alzheimers).

With supplements these days, it’s the Wild West. See, for example, Supplement Regulation and Side Effects: Efforts to Suppress the Truth (https://nutritionfacts.org/video/supplement-regulation-and-side-effects-efforts-to-suppress-the-truth).

  1. Disgusting. The company should be fined out of existence. They are scammers.

    But this is why I would rather get my B12 and long chained omega 3 from natural sources, even if it means including animal products in my plant based diet. I don’t trust companies making supplements. They are still too poorly regulated.

    Thank you, Dr Greger, for exposing this one.

  2. So rare to have a nutrition expert on youtube. It's a needle in a haystack. Thank you, Dr. over the counter drugs are still not tested by the USDA.

  3. Here's another way to spot snake oil, when ever you see a supplement advertised incessantly on TV, rest assured it's garbage. Can't recall the one I see all the time claiming to be the same as multiple portions of fruits and vegetables in just two tablets, but that's a great example. "We're Number One!!!… in letting multinational corporations do whatever they want to make a buck." Brought to you by your friendly neighborhood corrupt US government. 👽✌️

  4. "A 2019 survey by Pew found that more than half believed that the Food and Drug Administration requires supplements be tested for safety, BUT THAT ISNT TRUE." Are vaccines considered supplements? safe and effective.

  5. It's outrageous that the makers of products like this, both pharmaceuticals and supplements, can outright LIE about the efficacy of their product and still rake in the profits. Pharmaceutical companies especially should not be publicly traded entities beholden to shareholders–that's almost certainly a main motivation for deceit like that from the makers of Prevagen–and should be heavily regulated. They apparently are not, currently. Thanks for posting NF team!

  6. I get this question probably like once a month with some of my clients. The answer is no, they're all also corporate studies. Also these are older seniors with limited incomes they target.

  7. For many times i have asked you to share your blood results, bio age, Vo2 max and grip strength data but you are ignoring everybody. So this means your booking on aging is full of s>>>>.
    Please be transparent

  8. This was so timely! I was tempted to get this for my aging mother for the holidays after hearing the drumbeat of ads from the company on the radio. Also, I was recently arguing with a writer who submits fitness and exercise columns regarding the supplements he was recommending. I was trying to explain that the supplement market is woefully under-regulated and could be dangerous advice for our readers, but he was so dug in that I thought he may be getting a kickback from one of the companies.

  9. You have an article saying eggs are bad for you. Eggs are the perfect food. There is no other food that provides a more complete nutritional profile than eggs. In addition high cholesterol is healthy and prolongs life. Stop spreading dis information.

  10. Will be combing through your videos as I believe some of them to be mis/ dis information. Can’t let the stupids believe in that which is not accurate.

  11. What scientists nicely referred to as 'data-dredging' and 'cherry picking', would be called fraud in my book… This is completely insane!

  12. Well, Do the Doctors that prescribe this garbage aware of its ineffectiveness or are they lied to by their Big Pharma sales reps who wine and dine them about it? or Do these Big Pharma sales Reps even know its snake oil and just take the word of their employer that it works or do they simply don't care……..and only worried about putting money into their own pockets at the expense of people who are suffering with health issues………I suppose there is something to be said about the placebo effect here regarding this…..jellyfish protein.

  13. Reminds me of a wrinkle-reducing cream my friend used. She said it was "scientifically proven" to work. I pulled the ONLY paper the manufacturer cited on their website. The p value between the cream and placebo was 0.4 (not 0.04, but yes, 0.4), but it did not prevent them from advertising their "scientific evidence".

  14. Ok, so proteins are too large to get past the digestive system but what about peptides? I've recently heard about ones like Dihexa, RG3, FGL and a few others that are creating a stir.

  15. THNX A LOT. I HAD MY DOUBTS ABOUT IT, AND I NEVER BOUGHT IT BEC OF THE HIGH PRICE.
    GOES TO SHOW YOU THAT JUST BEC SOMETHING IS OVERPRICED DOESN'T MAKE IT GOOD QUALITY 🙄😹

  16. It shouldn't be on the market… these oversite agencies are not doing what I would expect them to do… how can I change that…

I commenti sono chiusi.
