Complete MRP powder (the primary supplement system): How Mourning Geckos Use It
Frequency
Every feeding, 3–4x per week
Role
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.

Calcium powder without D3 (for live insects only) is used dust fruit flies or crickets before offering, if offering them at all. Only relevant if supplementing with live feeders.
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.
