You could do a trial run with all three of the supplements you mentioned and see how you feel on them. Let us know the results- I'm curious!
I take a spirulina/women's multi-vitamin supplement because I probably don't have as balanced of a diet as I should and I know I'm not taking in enough of what I need through my food and I don't *ever* eat organ meats. In fact, I probably don't eat nearly enough meat. (You can blame my dad for terrible force feeds at the table as a child.) I know a supplement isn't the answer, but I like to think it at least helps.
