Guide de Nutrition Reptile 2026

Lizard diets vary hugely by species. Leopard geckos are insectivores, bearded dragons are omnivores, and iguanas are strict herbivores. One universal need: calcium and vitamin D3, whether through diet, supplements, or UVB lighting.

Aperçu des Besoins Nutritionnels

Metabolic bone disease (MBD) from calcium deficiency is the most common health problem in pet lizards. Feeder insects are naturally high in phosphorus and low in calcium, so dusting with calcium powder and gut-loading insects with nutritious food is essential. UVB lighting enables lizards to synthesize vitamin D3 for calcium absorption.

⚡ Nutriments Essentiels

Calcium

The most critical supplement for lizards. Deficiency causes metabolic bone disease (deformed bones, paralysis). Must be supplemented.

Meilleures Sources : Calcium powder (without D3 if UVB provided), cuttlebone, calcium-rich greens

Vitamin D3

Required for calcium absorption. Lizards synthesize it from UVB light, or it can be supplemented.

Meilleures Sources : UVB lighting (primary), D3 supplement powder

Vitamine A

Important for vision and immune health. Deficiency causes eye problems and respiratory infections.

Meilleures Sources : Gut-loaded insects, dark leafy greens, squash

🚫 Aliments à Éviter

Fireflies/Lightning Bugs

Extremely toxic to lizards — even one can be fatal. The toxin lucibufagin causes death.

Lettuce (Iceberg)

Almost no nutritional value. Fills up herbivorous lizards without providing nutrients.

Wild-caught Insects

May carry parasites or pesticide residue. Always use captive-bred feeder insects.

Spinach

Contains oxalates that bind calcium and prevent absorption. Use in small amounts only.

Avocat

Toxic to most reptiles. Can cause cardiac damage.

💡Conseils d'Alimentation Pro

✅

Dust feeder insects with calcium powder at every feeding for juveniles, every other feeding for adults

✅

Gut-load feeder insects with nutritious food (carrots, sweet potato, greens) 24 hours before offering

✅

Offer insects no larger than the space between the lizard's eyes to prevent choking

✅

Provide UVB lighting for 12-14 hours daily — replace UVB bulbs every 6 months as output diminishes

✅

For herbivorous species, offer a variety of dark leafy greens (collard, mustard, dandelion) daily

Questions Fréquemment Posées

What is metabolic bone disease?▼

MBD is caused by calcium deficiency and/or lack of UVB light. Symptoms include soft/bent bones, tremors, lethargy, and inability to walk. It is preventable with proper supplementation and lighting but often irreversible once advanced.

How do I gut-load feeder insects?▼

Feed your crickets, roaches, or mealworms a nutritious diet (carrots, squash, dark greens, commercial gut-load formula) for 24-48 hours before offering them to your lizard. This turns the insects into nutrient-delivery vehicles.

Can I feed my lizard only mealworms?▼

No — mealworms are high in fat and have a poor calcium-to-phosphorus ratio. They should be occasional treats. Crickets, dubia roaches, and black soldier fly larvae are better staple feeders.
