How to Choose

How to Choose the Right Reptile Diets and Supplements

Selecting the perfect nutrition for your reptile or amphibian comes down to understanding their specific metabolic needs and the bioavailability of the ingredients. The best products separate themselves by offering ultra-fine milling for better adhesion to feeder insects and using preformed vitamin A rather than beta-carotene, which many reptiles cannot efficiently synthesize.

Check the calcium to phosphorus ratio; a quality calcium supplement should be phosphorus-free unless specifically recommended by a vet for a diagnosed deficiency.

Ignore marketing claims about all-in-one miracle diets; most reptiles require a varied diet of live prey or fresh greens dusted with separate calcium and multivitamin powders on a rotating schedule.

Look for ultra-fine micro-precipitated calcium powders, as these stick much better to live feeder insects like crickets and dubia roaches than standard coarse powders.

Identify your species UVB setup before buying; reptiles housed with high-quality UVB lighting need calcium without Vitamin D3, while those without UVB require calcium with added D3 to process the mineral.
