Vitamin & Supplement Dosing Guide — Preventing Overdose with Proper Amounts

Supplements and vitamin additions are essential elements for maintaining the health of kept animals. However, adding too much based on the fear that "deficiency causes disease" can actually cause serious health damage. Vitamin A and D3 overdoses in particular can be fatal, making proper knowledge-based dosing management critical. This article provides detailed guidance on major supplement usage and precautions.

Calcium Supplement Basics

Calcium is the most important supplement in reptile keeping. Calcium deficiency causes metabolic bone disease (MBD), leading to bone deformation, trembling, appetite loss, and potentially death. Calcium powders come in two types: "with vitamin D3" and "without vitamin D3." In environments using UVB lights, animals can synthesize their own vitamin D3, so use D3-free calcium for dusting at every feeding and limit D3-containing calcium to 1-2 times weekly. Without UVB lighting, use D3-containing calcium at every feeding. The dusting method is simple: place feeder insects and calcium powder in a plastic bag and shake gently. Do not overfill with insects to ensure even coating. The calcium-to-phosphorus ratio is also important -- the ideal is 2:1. Crickets and mealworms are high in phosphorus and low in calcium, requiring calcium dusting to correct the balance.
