I recently started taking an omega-3 fish oil supplement with hopes of preserving cognitive function as I age. Cold-water fatty fish are a natural source of omega-3s and I haven’t been eating much lately. My supplement contains 1040 mg of omega-3 fatty acids. It’s a large pill that’s difficult to swallow sometimes.
Now I’m starting to wonder if I should continue. From Daily Mail:
The [single observational study] researchers compared 273 people who take omega-3 supplements daily, with 546 similar non-users – and found that those taking fish-oil pills appeared to decline faster on several cognitive scores.
However…
…when it comes to omega 3s and cognitive function, in a major [meta-analysis] review published recently in Scientific Reports, analysis of 58 randomised controlled trials from multiple countries suggested that omega-3 supplements may be associated with slightly better cognitive outcomes – or slower decline in some areas, particularly memory.

PS: There’s a diet linked to lower risk of cognitive decline and dementia. It’s the Mediterranean diet.
Diabetic Mediterranean Diet 
Hello Steve – this study was observational, and as you say, “There’s a diet linked to lower risk of cognitive decline and dementia. It’s the Mediterranean diet.”
I know the supplements market is huge and many do find them helpful and in some cases necessary.
I’m not a medical person but I would always advise supplements to be taken on the advice of your Doctor/medical team.
As I type this, it’ the weekend, I wish you a good one.
All the best Jan
