I’ve been taking about 3000mg of Omega-3 daily for about 6 months for reasons not related to lucid dreaming (I’m a bodybuilder so I take it for well being) and to be honest I never noticed any increased dream recall. Although that might just be me, if others are having success with it it must work I guess.
Regardless, everyone should implement Omega-3 into their diet as it does wonders for your body. I wouldn’t recommend getting cheap Omega-3 caps from some stores as they usually don’t contain large enough amounts of Omega-3 to have any noticeable effect.
I bought a years supply (365 capsules) of 1000mg Omega-3 capsules from eBay for £7 which is quite the bargain. Type “Omega 3 1000mg” into Google and you should find online shops that are selling the same thing. Actually some stores do sell high mg Omega-3, you just have to look at the packaging to see how much each cap gives you but its generally cheaper online.
