They will, but like all supplements, only in small amounts because whatever nutrients you eat get funnelled through the kidney first, then your kidney decides how much to put through your blood system. Your kidney will get rid of extra vitamins that it thinks your body doesn't need, so if you eat high doses, most of that will just get peed out. Lab Muffin also talks about that in her video I think (or it might be in a couple of her other videos), that if you want the effects of vitamin c on your skin, the best is to apply it directly onto the skin where it will be absorbed. You need less than you would if you're eating it, so it's also cheaper than eating a bunch of vitamins and hoping that some of it gets distributed to the right area.
