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."

What kind of insect in nature contain preformed vit A? i try to figure it out :/

could pieces of chicken liver or other animals be offered once a month as Vitamin A source?
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!
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!
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.
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.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.
Here is interesting read i found online

true. Just checking the options.I think that is a poor choice because it is too high in animal protein which can cause gout. Why wouldn't you use a known quantity (and hopefully quality) human-grade Vitamin A?
