nutrobal along with calcium?

[copper]

i'm replacing the vitamin supplement that i've used for Pihka to a better one, Nutrobal. the old being Nekton Rep.

as for my questions: with skinks, do you dust the meals with Nutrobal and calcium supplement. i'm wondering this because Nutrobal contains quite much calcium itself already. and if i need to use calcium suplement with it, i'd appreciate it a lot if you guys could suggest few high quality ones since i think there are better ones out there than the one i use now.
(i know how to use Nutrobal with calcium with leopard geckos because they have different needs..)

below are some info about the contents of the supplements:

Nutrobal:
contents per gram: 200mg calcium and 150IU D3 plus vitamins A E K B1 B2 B6 B12 C, folic acid, nicotinic & pantothenic acids, biotin choline inositol niacin and minerals Na Fe Co I Mn Zn Se Cu

Nekton MSA mineral and D3 vitamin supplement (this what i use at the moment)
i couldn't find specific contents per gram, the text on the bottle was in german but this is what i found on one site;
vitamin A, vitamin D3, vitamin E, thiamine, riboflavin, D-pantothenic acid, niacinamide, vitamin B6, folic acid, vitamin B12, vitamin C, vitamin K3.
Amino Acids L-lysine, DL-methionine Macro/Trace Minerals Manganese, zinc, copper, cobalt, iodine, magnesium, calcium.

Sounds like Nutrobal is a calcium supplement with other nutrients added, so I personally would not use another calcium supplement on top of it.
