Reptil Ernährungsleitfaden 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.

Überblick über die Ernährungsbedürfnisse

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.

⚡ Wichtige Nährstoffe

Kalzium

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

Beste Quellen: 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.

Beste Quellen: UVB lighting (primary), D3 supplement powder

Vitamin A

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

Beste Quellen: Gut-loaded insects, dark leafy greens, squash

🚫 Lebensmittel, die zu vermeiden sind

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.

Avocado

Toxic to most reptiles. Can cause cardiac damage.

💡Pro Fütterungstipps

✅

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

Häufig gestellte Fragen

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.
