@cec2 A couple of comments. Unless you really DO the Mediterranean Diet, instead of "trying" to do it, you're not really doing it. Just one or two days of sugar or things not on the diet can cause symptoms to flare. If it is a birthday or during Christmas, you can certainly eat some things off the diet. But do it in moderation and not for a long time.
B vitamins are water-soluble. The standards for "normal" in the medical community are very low. You cannot overdose on B vitamins but you should limit B6 because it can cause peripheral neuropathy. SmartB6 makes a B complex with no B6 for people who want to prevent peripheral neuropathy, which I have due to my blood cancer. Hydroxyurea and other chemo drugs are notorious for causing peripheral neuropathy. Once you get it, nerve damage in your feet, especially, cannot be reversed. I suffer from it as a result of my blood cancer. It's not "fun" at all. As for multiple vitamins, you're not going to get too much of anything if it is a multi with moderate amounts of vitamins and minerals. Extra iron, unless you have hemochromatosis or another iron-storage problem, helps women especially, and men as well. It's your choice. The maximum safe level for supplements, for vitamin D, for example, is 4000 IU (international units). I take 3500 IU daily. No issues.
I also have Macular Degeneration (dry not wet). The best helpers for that (and general eye health) are Lutein and Zeaxanthin. These carotenoids are found in leafy green vegetables and protect the macula from damage caused by blue light. Vitamins C and E are antioxidants that help to reduce **inflammation** and protect cells from damage or further damage. Zinc and copper minerals support the **immune function** and have antioxidant activity. See anything I mentioned before? INFLAMMATION and anti-oxidant supplements.
It's all up to you what you do or do not do.

Yes, I am.
