Anyone else find it ironic that there is so much anti-supplement fervor on a forum hosted by a guy who runs a supplement company?
Seriously, don't claim that you get all the micronutrients and minerals you need all the time from your diet. You may in most cases but I would argue that, short of testing the product in a lab, you really have no idea. Is the soil depleted and thus not passing along enough magnesium to your veggies? Who can say.
