can I see some links for that? I have read the opposite as well. Seems like there is lots of discussion on this. Like is it healthy to skip the precursor(beta-carotene) or it is healthy to just give the vitamin A.

You can research this yourself, but here's one good reference with the author's references as well.

Mader's REPTILE MEDICINE AND SURGERY, Second Edition. Page 289:

"In the early 1990s, a magazine article suggested that chameleons are susceptible to Vitamin A intoxication. After this unsubstantiated claim [emphasis mine], commercial dusts were marketed with only carotene as a Vitamin A source. Cases of Vitamin A deficiency in chameleons then began to appear. Affected Veiled and Panther chameleons show ocular lesions, respiratory dysfunction, spinal kinking, dysecdysis, and increased formation of hemipenal plugs."

The authors referenced:
Stahl SJ: Captive management, breeding and common medical problems of the veiled chameleon (Chamaeleo calyptratus) Proc Assoc Rept Amphib Vet 1997:29

What kind of insect in nature contain preformed vit A? i try to figure it out :/
 
Well then what is the preferred multivitamin with the acceptable form of vitamin A? And don't say reptivite.....
 
If someone can please make a comment about this supplement i am using for my chameleon... https://www.amazon.com/Repashy-Calcium-Plus-LoD-Sizes/dp/B00DLJRMV2
Look at the ingredients list. It seems that it has everything in there including Vitamin A. Do I still have to gut-load the crickets still? Please be aware that I do not want vitamin toxicity. Especially with fat soluble... it is hard to excrete. On google: The fat-soluble vitamins, A, D, E, and K, are stored in the body for long periods of time and generally pose a greater risk for toxicity when consumed in excess than water-soluble vitamins.

A dab of vitamin A oil (in the form of Retinyl Palmitate) once a month on the back of one bug does wonders for the health of Panther Chameleons! Especially for their eye health!!! Go to the drug store and buy the best quality they have! Poke a hole in a gell capsule with a needle and put the smudge of oil on the back or a cricket or worm!

That's what I do. Females producing eggs get it twice a month every once in awhile because they put enough Vitamin A into their eggs to last the babies for months.

It's not only eye health, but any duct in the body gets plugged up by improper shedding of the cells lining the duct. Kidneys, pancreas, etc. Even shedding is affected. So are sperm plugs.
 
When insects grow up wild and free they eat a much bigger variety of organic foods. All wild bugs therefore contain a much higher level of all vitamins and minerals than the insects we culture at home!

i Know for the vitamins but about the preformed A you have any scientific source to support it? or its just your impression? because if they can't convert non preformed source more than their need (the bugs:p), whats the difference between my gutloaded crickets and cricket in the wild, what about silk, horn or any other available food source?

And in the present case.. i propose to be caution vit Vit A problem.. there is a lot of other cause to a "one eye close problem" and.. Vit A are balanced with D3.. and Vit A are toxic so i suggest too really think how to help this animal and not jump in the first hypothesis (could be more dangerous than helpfull :/).. So for your cham, go to a good vet and ask for blood punction, maybe it can save your chameleon.. maybe there is a probleme other than vit A, maybe there is a small shedding piece it the eyes? of, sunburn? uvb sunburn? and a good checkup with the parameter can be a good idea.

in other hand.. you should try Vit A but low dosage and carefully!

to my part, i give preformed vit a every month too my chameleon but i have melleri and i think melleri need it because they eat small lizard and small animal (like small bird..) but does veiled eat small animals in nature?

of course.. we need more scientific prouf about the preformed Vit A issue and for the moment we just need to be carefull :/

Yes you will still need to gutload your insects if only to clear out their digestive tract of the chicken feed they feed them at the distributers, but it also will bring up their nutritional value. In the wild insects are contently feeding on a medley of plants and are much healthier for a reptile as a result.

I would still gutload the crickets. Just my opinion. If you feed them greens and veggies and a bit of fruit it shouldn't cause any problems.

Regarding the fat soluble vitamins...D3 and vitamin A shouldn't be toxic as long as the supplements are done properly. I've never investigated E or K but I imagine it's the same for them. D3 produced from UVB won't be overdone as long as the chameleon can move in and out if it at will so as long as you don't overdo the supplements it shouldn't build up. Vitamin A in greens and veggies is from beta carotene sources which don't build up so you just have to watch what you provide through the supplements. If, however you use a commercial feed...I can only say look at what's in it and figure it out from there.
