Question about calcium

[JeffreH]

I personally use the Rep-Cal line of supplements; have always been pleased with the quality and their products' ability to stick to feeders 'just right.' Most calcium supplements are essentially just calcium carbonate (typically derived from oyster shell), and in my opinion, as long as you are dusting on the right schedule, just about any type of reptile/amphibian calcium supplement should be fine. Calcium citrate can also be used and is more readily metabolized that calcium carbonate; but I find it unnecessary unless trying to boost calcium reserves for breeding animals or those recovering from deficiency (calcium glubionate is preferred for severe deficiencies).

Rep-Cal's multivitamin (Herptivite) also utilizes beta carotene instead of retinol as a vitamin A source, which essentially eliminates fear of vitamin A toxicity. I've been using their calcium, cal+D3, and mutlivitamin products for the last decade and my herps have all flourished. But everyone has their favorites ; )
