For all chameleons its important to have the right basking temperature to aid in proper digestion. (For an adult veiled female low to mid 80's.)
Its important to gutload/feed the insects a nutritious diet and to supplement the chameleons properly. Crickets can be gutloaded with a wide variety of greens (dandelion, kale, collards, endive, escarole, mustard greens, etc.) and veggies (carrots, squash, zucchini, sweet red pepper, sweet potato, etc.).
Because most feeder insects have a poor ratio of calcium to phosphorous, I dust the insects at most feedings with a phosphorous-free calcium powder.
I dust twice a month with a vitamin powder that contains a beta carotene source of vitamin A. Beta carotene won't build up in the system like preformed vitamin A will. It hasn't been proven whether all/any chameleons can convert beta carotene yet so some people give a little preformed once in a while. Excess preformed vitamin A can prevent the D3 from doing its job and push the chameleon towards MBD...so be careful.
I also dust twice a month with a phosphorous-free calcium/D3 powder. D3 from supplements can build up in the system too...so don't overdo it.
Exposure to UVB lighting allows the chameleon to produce D3 which allows it to use the calcium in its system.
Watering is important too.
Females can produce eggs even without being mated and so I always recommend that there is a suitable site in the cage at all times after the chameleon is 4 months old. If you don't provide a place for her to dig to lay eggs and you miss the sometimes subtle signs that she needs to she could become eggbound.
Its also important not to overfeed a female veiled so that she won't produce huge clutches. Overfeeding can also lead to prolapses, egglaying difficulties and constipation.
Hope this helps...sorry if its overwhelming.
