Laxatives AND Vitamin A?!
Question: Laxatives AND Vitamin A?
I don't see why not. 6 hours is generally more than enough time for your body to break down foods and nutrients for them to mostly (if not completely) absorb into your system... supplements (especially the base vitamins) generally break down even faster so you should have no problem.
Besides that, laxatives take time to work... but even still, it should be mostly if not completely absorbed already. Good luck and I hope I helped!
