Yeah I do have, I always said food grade is much better like use all the time supplements. Years ago Ive used so much nutrition(lazy) but when I started just eat properly without so much nutrition I was so surprise about effects of food grade power, of course I'm still take vit especially d3 and minerals like magnesium but when I calculated how much money I've spent for nutrition's so I made decision stay with food grade, better eat properly like chose easy way to make shakes every time. I even discover so many ways to prepare proper dish of nice and tasty food.
