I am working on improving my nutrition and in my reading figured out that I was probably severely deficient in DHA, one of the omega-3 fatty acids. This is the one that helps with brain function. (ALA, which I was already getting from plant sources such as flax seed, helps the heart.)
One of the reasons I was not previously taking an omega-3 supplement is that they usually come in these big horse pills that cannot be cut in half because they are filled with fish oil. I suppose you could just open the pill and eat the oil, but that doesn't sound very pleasant, does it?
Being one of those people with a bizarre psychological issue with pill swallowing (since I was a young child), I always look for alternatives to pills. I can take small pills (a small tablet is just fine), but larger pills I need to cut up and put into food to take. The main reason I have been remiss in taking supplements regularly is the pill factor.
