Fortifeye Vitamins Inc. is based in Ocala, Florida, and works in nutraceuticals rather than general groceries: its formulas are put together with input from healthcare professionals and revised as research develops. The catalog reaches past eye specific products into broader wellness, so several items here overlap the vitamins aisle as much as the eye care one.
Start with the category rather than the bottle. Omega formulas and carotenoid formulas are different things and are often taken alongside each other rather than instead of each other. The Next Gen products are broader, whole body formulas, so they are the ones most likely to overlap a multivitamin you already take.
Then look at count. Fortifeye labels most 90 count bottles as three month supplies, which makes comparing value straightforward between the 30 and 90 count versions of the same formula.
Because several of these formulas share ingredients, read the labels side by side before combining them so you know exactly what is in each. Anyone taking prescription medication or managing an eye condition should go through supplement choices with their eye doctor or physician.
