As for vitamins A/D/E: as you know, you can also get these from natural foods and sunlight!
I would definitely recommend getting "A" in the form of carotenes (like beta-carotene) or "provitamin A" from foods. Supplements may contain "a" in the form of retinal palmitate (?), which one can get too much of. The body converts carotenes to vitamin A on an "as needed" basis, so you can't get too many. Carrots and many dark orange fruits and dark leafy greens are a good source of carotenes. If you drink too much carrot juice, and your body doesn't need the carotenes, it will store excesses in the body, including in the epithlial cells of the skin, which can give one a yellowish tinge (though with your dark complexion, it might not show).
And vitamin D can be found in mushrooms and sunflower seeds, but is a hormone produced by our body in response to sunlight (not too much exposure, 10-15 minutes a day on 1/3 of your body, like arms and face, are enough for daily needs).
Healthy fats (raw, not cooked, which denatures them) are good as well. Olives or extra virgin, first cold pressed olive oil is good on salads (full of those dark green veggies!). Coconut oil, both internally and topically, is good. It contains medium-chaiin fatty acids/medium-chain triglycerides that are very similar to the makeup of our own skin oils.
Eating high raw is a good idea as well, and easy to do in the summer months, when there is a lot of variety in fruits and veggies available (organic, of course!).
And definitely water!
Doing a detox (like a week of just fresh juices and raw foods) can help give you a head start.
