Imo the most cost effective supplements(biggest bang for the buck) are

1) Vitamin C- Very cheap, especially when bought in bulk by the pound.

2) B vitamins. Generic B50 tablets might be under $5 for 100.

3) Cayenne powder-Very inexpensive, but make sure you get a very hot variety. The mild ones are almost worthless
4) Garlic- Raw garlic is best, but if you can't stand it, then garlic powder or garlic pills could be used.

5) cinnamon
6) Licorice root
