So, can bearded dragons eat spinach? Great question! If you’re cutting up lettuce for a salad and wondering how much spinach you can feed to your bearded dragon, here is the answer – and why: raw spinach is healthy for people but poses some unusual challenges to bearded dragons because of its nutrient profile.

The Nutritional Content of Spinach
Spinach has elevated levels of vitamins A, C and K, as well as iron, but those vitamins could be relevant to bearded dragons in precisely the opposite way to the way that those same vitamins might be relevant to us. So let;s go back to our main question “Can Bearded Dragons Eat Spinach?”. Let’s first consider the risks involved –
Risks of Feeding Spinach to Bearded Dragons
High Oxalate Content
The anti-nutritional plant compounds called oxalates, present in spinach, can lead to serious problems with a bearded dragon’s bones. Oxalates bind with calcium, inhibiting it from entering the body. Adequate amounts of the mineral are needed for forming and maintaining bones, and metabolic bone disease can impact how they develop if they are not available. High levels of oxalates in spinach make it possible for calcium to create a depleted condition, one that might lead to deformed bones, pain and possibly death, over time, if left untreated.
Unfavorable Calcium to Phosphorus Ratio
You’re supposed to eat it in a certain ratio of calcium to phosphorus, and spinach has too much phosphorus and not enough calcium. So that’s one of the things wrong with high-nutrient plants.
And since that phosphorus has to compete with the animal’s calcification needs – its primary battle being with calcium, after all, which as we’ll see is also not that easily unlocked – the greater phosphorus content of the plant is actually associated with less calcium, not more.
And it’s not just about less calcium: it could be about problems with calcium metabolism in general and with consequences as serious as osteoporosis.
Additional Risks to Consider
Vitamin A Overdose – While spinach is a great source for a bearded dragon’s need for Vitamin A (maintaining the dragon’s immune system and balancing its vision and skin), if overfed, the dragon will develop a condition known as hypervitaminosis A causing them to become protruded, lazy, and can cause damage to its internal organs.
Digestive issues – Food high in fibre (such as spinach and carrots) shouldn’t be fed to a bearded dragon that isn’t on a high-fibre diet, as it may end up with an upset stomach, discomfort or diarrhoea that can lead to dehydration and exacerbate absorption issues.
Pesticide Overexposure – Like most leafy greens, spinach is almost always sprayed with pesticides while it is grown. Unless it is organic and you are feeding it organic spinach, and it is thoroughly washed, the pest repellent-type chemicals that are present on the leaves of the spinach can be toxic to your bearded dragon.
The risks outlined above mean that you are probably better off avoiding feeding your bearded dragon spinach altogether, or at least feeding it quite rarely, and – to counteract some of the oxalates and phosphorus in it – giving it alongside food that is calcium-rich.
Do please check with a reptile-savvy vet before you swear off feeding your bearded dragon something if it seems that eating it may interfere with their body and health-maintenance circuits.
Potential Benefits of Spinach – Can Bearded Dragons Eat Spinach?
Water/Fibre – Because of their high water content and fibre, these may help with digestion and hydration in beardies.
Vitamins – Bearded dragons will definitely benefit from the vitamins in spinach if there are no problematic issues with the oxalates.
Guidelines for Feeding Spinach
Give As Needed: Should you choose to give your bearded dragon an occasional spinach, give it infrequently and only in small amounts. It is by no means necessary (can bearded dragons eat spinach? Yes technically but not recommended at all).
Instructions for use: Wash thoroughly to get rid of pesticide, cut into pieces to eat it easily.
Dietary Balance: Serve with phosphorus- and oxalate-counteracts, such as collard greens or butternut squash.
Better Alternatives to Spinach
Given the risks associated with spinach, consider these safer alternatives for your bearded dragon:
Collard greens: A good choice, safer thanks to the better calcium:phosphorus ratio, and lower in oxalates.
Mustard Greens: Another excellent alternative, rich in calcium and safer for regular consumption.
Dandelion Greens: Nutritious and generally well-tolerated by bearded dragons.
Conclusion
Alright! Let’s conclude.. can Bearded Dragons eat spinach really? Spinach is another food often regarded by popular opinion as being okay for your bearded dragon, but in reality it has too many risks and offers too little benefit, especially considering the multitude of better alternatives that are at your disposal.
It’s technically possible to include spinach in the diet, but it’s usually a better idea to limit its use dramatically and pair it with other calcium foods at every feeding.
For your normal, daily green offerings to your dragon, stick to vegetables that have fewer negatives along with the positive offered by greens. As always with any pet, consult with a vet that’s knowledgeable about reptiles to help design the diet around your individual pet and keep them healthy and happy.
