M and empty stomach

I know this has probably been answered before, but I can’t find it on the search engine. Does it matter if you take M on an empty stomach or not?

It does NOT matter.

I’ve read Bill Roberts as saying that herbs have higher absorbtion when taken with food. So the Vitex would theoretically be best absorbed on a full stomach. As for the other ingredients, I’m not sure. The difference would probably be negligable, though.
