You said: "Isn't "A" what "they" are advising against now?"
I have no clue! who's they? However it is important to purchase a good brand of fish oil so as to avoid mercury contamination.
I have so many supplements myself. Fish oil, cal/mag/zc, vit B., vit. C, linseed oil, yogurt and lecithin is what I recommend as a basic protocol to carry on until you are cured of candida.
ALways buy the liquid formula, the pills that liquefy in water is the second best option and the gelule still better than difficult to digest pills.
As for any other I avoid mixing and try to have them one at a time.
I currently take gingko biloba for my sinus. I had a lot of sinus die-off associated with my 15 days fast and I feel I should work on it.
