Calcium powder without D3 (for live insects only): How Mourning Geckos Use It
Frequency
Dust fruit flies or crickets before offering, if offering them at all
Role
Only relevant if supplementing with live feeders. Since MRP already supplies calcium and D3, this is a lighter-touch addition than in an insectivorous species' routine — it's there to balance the phosphorus-heavy live insects, not to replace MRP's role.

Complete MRP powder (the primary supplement system) is used every feeding, 3–4x per week. A quality commercial gecko MRP (Pangea, Repashy) already contains balanced calcium, D3, protein, and vitamins — it functions as both food and supplement simultaneously, which simplifies supplementation considerably and is exactly why it works so well for a nectivorous species this small..
Multivitamin powder is used generally unnecessary if feeding a quality complete mrp consistently. Most keepers relying on MRP as the diet base don't need a separate multivitamin — over-supplementing on top of an already-complete diet risks vitamin A and D3 excess.
