Can you recommend a good supplement for supporting methylation? Or would you say just following the protocol will be all we need to do to support methylation?

Following the protocol is all you need. Just focus on that. Don’t get distracted by all the methylation supplements out there. There’s no “one supplement” that you can take. 

The Life Extension Two-Per Day multivitamin would be the closest thing to an “all-in-one supplement”. So you can take that. But alone, it’s still not enough.
