D3 overdose.??

Just curious as to. What happens if a cham overdoses on D3? Many times i've read they can. But never found out what happens when they do. Can anyone help me out?

One of the issues created by overdosing D3 is that your chameleon will metabolize far too much Calcium into serum form. It will force calcification of the muscle tissue. Often you will see your chameleons back legs move in a rigid tripod type of motion. You may also see calcium deposits along the ribs.

I agree with Harry. Excessive vitamin D3 supplementation can result in organ toxicity (gular edema)metastatic calcification and gout.

just more agreement with the above

Excess D3 actually causes absorption of bone and mineralization of organs

Thank you very much for the information.

Good to know. Thanks.

I was told to much d3 can eventually cause kidney disease's or problems for the chams at a later age =/

herein lies your answer, much of it has already been said.
D3

and before everyone asks
vitaminA

same author ken lopez dvm, you may note, (unlike ivan alfonso) hes not a big fan of preformedA, figure sandra chameleon may get a kick out of that one. lol

by the way, imo, its rarely just a question of too much D3, but a question of too much D3 in relation to vitaminA, calcium and water are also big players, all in relation to the calcium/water/nutrition/light intake. the same could be said of vitaminA. imo, its all inseparable.

generally speaking you want to maintain a ratio of 1 part D3 to 10 parts preformed vitaminA (or its proformed equivalent, and of course we have no way of knowing what that is), without giving too much of either. just for the record, since its been the subject of several recent posts, thats the ratio in repashy calcium plus icb.(D3/preformedA@1;10) jmo

does this harm older chams more them younger? im a little concerned because waldo got it everyday for atleast a month they told me to use it on every feeding altho i seriously think they probibly use nothing. and that was what they recomended i used. i didnt learn for almost a month not to. how long are we talking before it would cause problems to a baby?

Could you please describe the 'rigid tripod motion'?

Thx,

but yes id like to know what that looks like,

Your chameleon will probably be fine. D3 over-supplementation is a little harder to achieve than it may seem when discussing optimal supplementation schedule.

To give you an idea of why I say this- I used d3 every feeding throughout the first part of the 1990s and in the latter part used d3 every indoor feeding, but not outdoor feeding. I produced literally thousands of baby chameleons and had dozens of breeders of different species at an given time.

I *never* saw symptoms of over-supplementation in a single chameleon.

And necropsies were done on many animals over the decade as well. Casual necropsies where samples were not sent off to the lab or anything, but many were done with veterinary supervision especially before I had much of an idea of what I was looking at (I come from a veterinary family- father and one of my siblings, also friends and relations because I was raised in a vet-school community with best friend's father also a vet, and one of my best friends as an adult also a vet. In the 90s I still lived about 45 minutes from where I grew up). So while I'm not a vet saying this, I'm also not the average joe keeping one or two pets never having someone who knows what they are looking at see their animals making this observation either...

A month of daily d3 is unlikely to have created any problems. I'm not recommending anyone do what I was doing- I don't even do that any more (though I use more than most here seem to. I think some have gone from my old extreme to the opposite extreme - but I'll be switching to rapeshy product in 2012 when I run out of supplements). A more moderate amount is a much better idea combined with good lighting. But if I were you I wouldn't loose much sleep over a month of daily d3 use either. Your lizard should be just fine...

ty very much. put me at ease.
