There is only one brand of IP-6 sold on Amazon. It is a component of fiber? Soundz good! But it is pricey. $21.46 is the sale price. Also, won't 6-10 grams a day of Vitamin C "wash away" other nutrients or cause an imbalance? Would you recommend that amount for just a short duration, or long term? I have the 1,000 mg tablets.
