Multi-Vitamin Advice?

I recently received a Vegan multivitamin produced by Deva called “VEGAN MULTIVITAMIN & MINERAL SUPPLEMENT”

vitamins for wellness

What I would like to know is if this vitamin is safe to take once per week or two weeks. There’s a high concentration of certain vitamins and I don’t want to over inundate. I am eating a fairly balanced diet, so I probably only really need the B12 and maybe the Iodine.

Vitamins A and D2 . . . 100%
C . . . 250%
E . . . 167%
B’s:
1 . . . 833%
2 . . . 735%
3 . . . 250%
5 . . . 250%
6 . . . 625%
12 . . . 1332% (seem a little high for a daily?)
Folic Acid, Iodine, Selenium, Manganese, Chromium, and Molybdenum . . . 100%
Biotin . . . 25%
Calcium . . . 10%
Magnesium . . . 5%
Copper . . . 50%
Other ingredients with no %DV are Boron, Choline, Inositol, Lutein, PABA, Citrus Bioflavinoids, Pectin, Betaine Hcl, Afaalfa Medicago Sativa, Chamomile Matricaria Recutita, Rose Hips Rosa Canina, Rutin, Parsley Petoselinum Sativum, and Acercola Extract Malphighi Giabra
