I'm trying a bit of a shotgun approach, which is getting costly. I'm wondering what I should start cutting back on... CoQ10 is expensive and I haven't noticed a huge difference with it (though everyone has recommended it, including a doctor whose opinion I value greatly). I have other things that work well for energy levels. What about immune strengtheners or natural antivirals? Monolaurin doesn't seem to do much, ditto Red Marine Algae. They aren't bank-breakers but they aren't cheap, either.
