feeding problems with bandie?

my leopard gecko as grown on me now the past couple months and i can finally take her out without her trying to run away, we dont take her out very often, maybe twice to three times within a period of seven days ... i recently started dusting the crickets with 1 part calcium+D3 and 1 part multi vitamin powder... and now she's being very picky on eating them... she seems healthy beside the eating factor .. i got her to eat two super worms in the past 3 days , shes still active in her viv, i give her fresh water every day ..
i'm just wondering if i should switch back to just using the regular calicum powder i also have? any ideas or tipss??

she not loosing any weight either and is going to the bathroom normally.

It's important to try to get those vitamins in but they don't seem to like them! Try reducing the amount you are using, just use a tiny bit. Increase it over time. Use the D3 once or twice a week, the vitamins once or twice a week and pure calcium the rest of the time. Don't mix them, it may be easier to get her to eat that way. Go light on the dusting 'til she gets the hang of it.

i can get her to eat 1 super-worm or 2 meal-worms a day,, she wont touch the crickets at all :(
