How Calcium To Phosphorous Ratio Affects Your Crestie

Crested geckos should eat a diet that has a Ca:P ratio of 2:1, 1:1, or 1:0.5. The ratio you decide to feed your gecko can affect their growth, metabolism, and health.

If the gecko consumes calcium above what it needs, it is excreted in its urine.

If they consume too much phosphorus, they store it in their bones and teeth, which can lead to problems like kidney stones and metabolic bone disease.

What Is The Ratio Of Calcium To Phosphorus In Passion Fruit?

The ratio of calcium to phosphorus in passion fruit is 1:5.65 which indicates that there is 5.65 times the amount of phosphorus as calcium in the passion fruit.

How To Calculate Ca:P Ratio

You can figure this out by calculating the Ca:P ratio using the formula given below.

According to the nutritional content, the Ca:P ratio is 28.3mg:160mg. Dividing through by 5.65mg (calcium). The ratio becomes 1:5.65.

How Does Oxalic Acid Affect Your Pet?

Oxalic acid is not a nutrient or essential dietary component and it is not required for normal growth or health.

When oxalic acid is consumed, it binds to the calcium and magnesium in the body and prevents them from being absorbed.

This can lead to calcium deficiency which can be harmful to your pet. Crested geckos are strict insectivores and may not benefit from the oxalic acid in the food and may not be able to digest it.

Some people recommend soaking and rinsing the fruits to get rid of the oxalic acid. However, this is not proven to be effective.
