supplement

[HtVic]

the one I have is repti supplement calcium without D3, is that ok?
'cause I've heard that if your tortoise get enough uv from uv light, then you don't need supplement that contains D3, otherwise, too much D3 will cause some sort of disorder

The way I understand it is if they don't get a lot of natural sun light, then they do need the d3. Hang on for more opinions.

ok, awaiting.....

If they have access to good sunlight- roughly an hour a week or so over several sessions, then you don't need extra D3. If the main source is a UVB bulb, then the extra D3 in the mix is neutral- possibly helpful but possibly unneeded but almost certainly not enough to cause a problem.

I agree.
