Meep!
Good then, that. I love how thorough Dr. Buist is in the doc!
Personally I keep the vit C as ester-C and below 1000 mg / day. It can run some mess on your kidneys at too high a dose, so I use MK7 (K2 / nattokinkase) on the side. Really good against depression, amazingly enough. :)
Type 1 diabetic here, it's been great finding out that some stuff works on me (BTW, dropping flouride toothpaste is a good thing too..! Iodine chases out flouride, but best not to tempt the fates. )
