I use what I can get. In India its difficult to get any brand of CLO other than SeaCod. There are some capsules for O3, but I think CLO is much better than concentrated O3 capsules, because it is natural stuff. It contains other things beside O3. I might have tried other fish oils, if they were available, but probably would have gone for the cheapest ;-).
Women probably would do good on simple mustard oil as well, as they convert some ALA to EPA and DHA. My wife has good HDL level of 59. I have only 31 :-(. Could it be that I am not having enough EPA?
