Males, females, neonates and juveniles all have different needs.
I'd even consider the care so different that you'd think they are different species alltogether.
Females of course need much more calcium, d3, and multi vitamin. The high dose repcal with d3 (400,000 IU of d3/KG), and herptivite would be good for adult females at early gestation and when they are gravid, and then again after laying to build calcium stores up in the body. Since calcium and d3 has calcium in it (a lot of people seem to forget that), then it might be a good idea to use a low dose ca and d3 dust such as Zoomed's (10,000-12,000 IU d3/kg) once every two days or so.
Alternatively, you could dust lightly every feeding with a low dose d3 such as Miner-all 1 (4,400 IU of d3/kg)
Babies need almost the same schedule as gravid females, until they are about full grown, but should have insects available at all times, whereas females should be watched to not over-eat which could cause complications.
Adult males need much less, calcium once or twice a week, d3 once or twice a month, and herptivite once or twice a month. Since males don't have the physical demand of making eggs, they tend to be much pickier with their food, and offering them a variety of insects alone will meet most of their nutritional needs.
I think over-supplementation is too common in all reptiles. My friend Shwa whose female veiled lived just over 10 years, he said his only secret is 'I don't overdo it on the supplements.' His male lived 13 years.
Gutload & a good UVB bulb is the best way to go for adult males, with this you only have to dust with calcium maybe once or twice a month (depending on what feeders you are using).
There are a LOT of variables. If you are using crickets and mealworms, yes you have to supplement more. If you are using silkworms, phoenix worms, butterworms, and roaches, then no you don't have to supplement near as much as most people do.
Think of supplements as sprinkling salt and pepper on YOUR food. You don't need much to get the desired effects, too much and you run into problems.
At the end of the day, quality insects and gutload + UVB or sunlight is all you need, babies and gravid females require a little extra for obvious reasons.
