I'm unsure about the Vitamin C combos from Supplement Clinic, mainly because they're synthetic, plus I live in the UK.
I think I would consult Lam first about dosing with his supplements, so I'd have to be bound to his program, which many people are already questioning around here.
I was going to try natural vitamin C (in a self-guided fashion) along with my own L-Proline and L-Lysine supplements (1g per day)) and mineral supplements to gauge the effect (as well as pantethine in equivalent doses).
Like I said, I'm really unsure where to start and was looking for "elders" to relate their experiences.
Dealing with pronounced organ insufficiency is quite a challenge to meet! ;-))
