Omega-3 supplements may be linked to faster cognitive decline in seniors, study finds

Agreed.

There are many. many studies that IIRC observe the precise opposite.

Thanks to CM for posting the article, it's always good to see every angle, however one does suspect that this is pure poop.

I didn't check, however I would not be surprised to learn that at least part of the funding for the study was somehow connected to big pharma.

Fish oil may be hurting your brain, new study finds
April 26, 2026
Medical University of South Carolina

Summary:

Fish oil has long been praised as brain-boosting, but new research suggests the story may be more complicated. Scientists found that in people with repeated mild head injuries, a key omega-3 fatty acid in fish oil—EPA—may actually interfere with the brain’s ability to repair itself. Instead of helping recovery, it appears to weaken blood vessel stability, disrupt healing signals, and even contribute to harmful protein buildup linked to cognitive decline.

A new study from the Medical University of South Carolina is raising fresh concerns about fish oil supplements, especially for people who experience repeated mild traumatic brain injuries. Writing in the journal Cell Reports, researchers report that these widely used supplements, often promoted as protective for the brain, could actually interfere with healing after injury.

The research was led by neuroscientist Onder Albayram, Ph.D., an associate professor at MUSC and a member of the National Trauma Society Committee. His team focused on the biological processes involved in repairing blood vessels in the brain after injury. Rising Popularity of Omega-3 Supplements Interest in omega-3 fatty acids, the key components of fish oil, has been growing rapidly. According to Fortune Business Insights, these supplements are now appearing not only in capsules but also in drinks, dairy alternatives, and snack products. That surge in popularity does not surprise Albayram. "Fish oil supplements are everywhere, and people take them for a range of reasons, often without a clear understanding of their long-term effects," he said. "But in terms of neuroscience, we still don't know whether the brain has resilience or resistance to this supplement. That's why ours is the first such study in the field."

Is coffee good for you or bad for you today?

Scientists just discovered what coffee is really doing to your gut and brain

Kippered herrings are not only an excellent source of omega 3, they are delicious. I eat a canful 3-4 times a week. Not at all weird or gross like some canned fish. Smoked fillets.

[Jeff Chandler]

I understand that Pepcid is much gentler than Prilosec. You’re probably okay with it.

I’m still waiting for the final scientific verdict on bacon and eggs.

[Red Badger]

Everything in moderation. Especially moderation................

[Myrddin]

I understand that Pepcid is much gentler than Prilosec. You’re probably okay with it.

My daily routine includes 20 mg famotidine in the morning and evening. It seems to be working Ok. I have to avoid lactose, excessive fat and excessive spice. When I fail to do that, I pay an uncomfortable price. The less efficient digestive process demands 2,000 calories or I lose weight. Prior to the surgery, I maintained a steady weight with 1250 calories 5 days per week and 600 calories 2 days per week.

I don’t know about the “maximum dose” part, but generally speaking I think your doctor was on the right track.

“Decaf even improved learning and memory, while caffeine boosted focus and reduced anxiety. “

Key takeaway: Swallow your fish oil with coffee!

[Deo volente]

Four cups of coffee each day, and still going strong in my early 70’s.

J.S. Bach drank as many as 20 cups a day of the stuff and composed over 1,000 pieces of music, many of them masterworks. He also lived to 65 which was very old back then (1750).

I thought fish, high in Omega-3, was considered brain food.

My cardiologist was the one who recommended Omega 3s for me.

Well this stuff is not “man made” artificial - it is actually fish oil, taken from fish.

Maybe it has something to do with it being absorbed too much, too fast vs. in fish itself?

[higgmeister]

Two PPIs had horrible side effects and famotidine is not a PPI so you are good.   "Live long and prosper!"

I was just having fun about the Doctors practicing medicine.   I actually appreciate what modern medicine has been able to do in the past fifty or sixty years (not the Covid Fiasco).   Even your Whipple procedure seems to be happening all over.

[OrangeHoof]

Well, I take those thingies...those, um, capsules and I never had a problem with my memory, not once. Now, what were we talking about?

[GOPJ]

You remember that?

[b4me]

yup! We would be healthier and need less supplements if we eat real (as unprocessed by factories etc as possible) foods.

If we stop leaning on convenience and get back to making some of our own meals and snacks as much as possible

some snacks are super easy, like an apple sprinkled with cinnamoninstead of baked apple dessert from store that is heavily processed, sat frozen for a while, they thawed it, baked it, and it sits in plastic container waiting for you to buy it. And you can always cut the apple, put it in a bit of water in a pot and cook it yourself for 5-10 minutes then when removed from heat sprinkle in your cinnamon and a few raisins or dried fruit and walnuts and it’s like eating insides of apple pie without added sugar or dough conditioners and processed flour to spike your blood sugar or otherwise mess up your metabolism and body.

About Omega 3, eat sardines or other oily fish (low mercury ones) a couple times a week and you don’t need to buy omega supplements.

[b4me]

I didnt fully read the article, but did they talk about the some times rancidity of fish oil capsules after processing? rancid oils consumed are not helpful to the body, even the cooking oils, especially the ones in clear bottles or plastic. We’ve been indoctrinated to think we can have easy convenience with so many things about easy ways to fuel the body when most of it is crap food, like putting wrong gas in your cars gas t

Many many people are creating their own disease by what they drink and eat.
