60 grams of vitamin C? Don't you mean 6 grams? 6 grams is 6,000 mg of C. 60 grams is 60,000! I never heard of anyone taking such a high dose.
No, sorry, I have no experience with those other forms of ascorbate, only sodium ascorbate and calcium ascorbate.
I'm not sure what your issue is with sodium ascorbate. It's the form most often recommended by the vitamin C experts. Anyway, hope someone else here can help you!
