Need some schooling on vitamins and supplements please?

I do the magnesium for leg cramps also. But what I use for arthritis pain is a cup of aloe vera juice in my V8 each day. The V8 greens helps with your eyes. What you want is the spinach it helps in that area. It takes about 30 days for the aloe vera juice to kick in. But what happens is the pain of getting up and down is all of a sudden it's gone but you don't notice that . Later on your thinking where did that pain go.
