Omega 3 Supplements Probably Don't Slow Aging

Despite the breathy headlines, new findings about Omega 3 oils are very uninspiring.

Hi all! This piece is a paid-only one for my paid subscribers. If you’d like to support my writing, please do consider upgrading to a paid subscription. I currently have 248 wonderful paid subscribers, which is far more than I thought I’d have on this platform. I would really like to start expanding my content on Substack, but I need some more subscribers to do so! If I can make it to 500 paid subscribers, I want to re-start my podcast focusing on sensationalized science in the media, and also get some freelance pieces by medical and health journalists. If that sounds good to you, sign up!

Cheers, Gideon.

Omega-3 supplements have been a contentious issue for decades. The global market for omega-3 supplements - which are mostly some form of fish oil - is reportedly in the billions and set to grow enormously in the coming years. If you believe the marketing of these supplements, they help with everything from brain to heart health and can improve your wellbeing in myriad ways.

Scientifically, however, there’s not much data showing that they work. Or rather, the available scientific evidence - which includes gold standard randomized trials - seems to show that for the majority of conditions omega 3 supplements probably do little or nothing.

Recently, headlines have contradicted this evidence. Media from around the world is reporting that omega-3 supplements can make slow down aging and make you live longer.
