Best Calcium + D3 Supplement?

[FallOutFighter]

My crested gecko is kept on a Repashy only diet. I would like to feed crickets once or maybe twice a month. Does the Repashy have enough calcium and D3 to cover cricket feeding once in a while? If not which one of these calcium + D3 supplements is the best one that has the right amount of D3?

I use Zoo Med, personally. A lot of my friends who are breeders use Zoo Med as well.
