There's no specific brand I recommend per se. The type of vitamin C is debatable but I would not use buffered or slow release vitamin C. Try to avoid anything from Chyna.

Liposomal vitamin C might be the best as others have pointed out.

Please read the post linked above for specific instructions because different foods compete with vitamin C and lysine respectively.
Without the competition, your blood level of these supplements spikes dramatically and magic happens.
