For today’s edition of Dear Mark, I’ll be answering your CBD questions from the past few weeks. CBD, or cannabidiol, is exploding in popularity, but there are many unknowns. People have a lot of questions and there aren’t many definitive or comprehensive guides, so today I’ll do my best to make sense of it. We’re...

For today’s edition of Dear Mark, I’m answering three questions. You guys had more questions about folate. Since it’s such an important vitamin, I answer those first.
