I have sinus issues, fungal/candida problems, hormone imbalances and mild depression. One of the things my doctor told me to take is cod liver oil. This is more easily digestable than capsules, and you only have to take one tsp per day - as opposed to a bunch of pills. I was pleasantly surprised by the flavor, as well. In a short time I can already tell a difference in my mood. It's hard to explain but I just feel calmer and more peaceful. As a side note - I gave cod liver oil to my daughter when she was young and it totally stopped her recurring ear infections. I have put both my kids (13 and 11) back on it to help them fight off viruses this winter.
