i was told by flchams to give rep-cal calcium with vitimin d3 3 times a week and herptivite once a week is this alright because ive been doing it for a month now and my cham is doing great
Three times a week seems too much for that particular D3 supplement. Its the one I use, but its also very potent. I use it once every other week. I use vitamin supplement every other week (oposite week to d3). I use plain calcium on most every cricket (though not necessarily on every other type of insect I offer - crickets are in no way the only insect I use).
There is no single supplement schedule that fits all situations. What I do, what works well for me, what anyone else says, may not be the best choice for you and your chameleon. Those that get access to sunlight need very little D3 in their diet, if any. The type of insects offered can make a difference (crickets have a poor calcium to phos ratio, some other bugs are better in this regard). Those with excellent gutloading and a variety of prey insects may need less supplementation dusted on prey than others. The brand of supplement makes a considerable difference. Rep-Cal has 400,000 IU/kg of D3 whereas Miner-All (I) has 4,400 IU/kg of D3 and I think 150IU D3 in Nutribol (which also has Vit A so be wary of using this very often). That's a considerable difference in D3 strength. Herptivite uses beta carotene, so is very safe (but does not provide prEformed A). Reptivite has some preformed vitamin A and thus should be used cautiously (especially if you are direct supplementing with preformed A in other ways) with this in mind. The age and type of chameleon also influences supplement choices.
Only you can decide what works for your situation, for your chameleons situation.
