Is sweet potato good for bearded dragons?

Quick Answers

Sweet potatoes can be an excellent treat for bearded dragons in moderation. They provide beneficial vitamins, minerals, and antioxidants. However, too much sweet potato may lead to health issues like diarrhea, obesity, and vitamin A toxicity. Following proper preparation, portion size, and frequency recommendations allows sweet potato to be a nutritious part of a varied diet for bearded dragons.

Nutritional Profile of Sweet Potatoes

Sweet potatoes are packed with nutrients that can support a bearded dragon’s health when consumed in moderation. Some of the main beneficial nutrients found in sweet potato include:

Vitamin A

Sweet potatoes are very high in beta carotene, which the body converts into vitamin A. Vitamin A supports immune function, vision, and skin/bone health in reptiles. However, excessive vitamin A can be toxic.

Vitamin C

This vitamin acts as an antioxidant and supports collagen production and immune function. Vitamin C deficiencies are rare but can cause health issues in bearded dragons.

B Vitamins

Sweet potato provides small amounts of B vitamins like niacin, pyridoxine, and pantothenic acid. These aid metabolism and energy production.


This mineral is essential for proper bone development and preventing metabolic bone disease in bearded dragons. Sweet potato contains some calcium, but calcium supplements are still needed.


Phosphorus works with calcium to support bone health. It is abundant in sweet potatoes.


Magnesium is needed for energy metabolism and nerve function. Sweet potatoes provide modest amounts.


This mineral supports fluid balance, nerve signals, and muscle contractions. Sweet potatoes are a good source.


The fiber in sweet potato provides bulk for healthy digestion and prevention of constipation issues common in captive bearded dragons.

Benefits of Sweet Potato for Bearded Dragons

When fed properly, sweet potatoes can provide the following benefits for bearded dragons:

Nutrient-Dense Carbohydrate Source

The complex carbohydrates in sweet potato provide a healthy source of energy and nutrients compared to unhealthy options like fruit.

Supports Immune Function

The vitamin C and vitamin A in sweet potatoes help maintain a strong immune system to fight infections.

Encourages Healthy Digestion

The fiber content helps food pass smoothly through the gut and prevents digestive issues like constipation.

Promotes Bone Health

Phosphorus, calcium, and vitamin D in sweet potatoes support proper bone development when combined with UVB light exposure and calcium supplements.

Provides Antioxidants

Antioxidants like vitamin C and beta carotene help counteract harmful oxidative damage to cells and tissues.

Potential Concerns of Sweet Potatoes for Bearded Dragons

While nutritious in moderation, sweet potatoes do come with some cautions for bearded dragon care, including:

High Natural Sugar Content

Excess dietary sugar from sweet potato or other fruits/veggies can potentially cause obesity, diabetes, liver and kidney issues over time.

Risk of Vitamin A Toxicity

Excess preformed vitamin A from animal sources is dangerous, but excess beta carotene from sweet potatoes is less likely to cause toxicity.

Oxalates May Bind Calcium

Oxalic acid in sweet potatoes can potentially bind to calcium in the gut, reducing calcium absorption. Proper calcium supplements help overcome this.

Diarrhea with Too Much or Too Often

Frequent high amounts of sweet potato may cause loose stool or diarrhea due to high water and sugar content.

Higher Phosphorus Than Calcium

The calcium:phosphorus ratio is slightly less than ideal at 1:2, but proper calcium supplementation again prevents deficiency.

Are Sweet Potatoes Safe for Baby Bearded Dragons?

Baby and juvenile bearded dragons under 18 months old have specific dietary needs. A small amount of cooked sweet potato, once or twice a week is fine but not ideal as a staple due to:

  • Higher phosphorus content – juveniles need a 2:1 calcium:phosphorus ratio for bone growth.
  • Lower calcium than greens like collard/mustard/turnip greens.
  • High sugar content for small dragon digestive systems.

Small pieces of sweet potato should complement a staple diet of calcium-rich, low-sugar greens, vegetables, and quality protein sources for growing beardies.

Can You Feed Bearded Dragons Raw Sweet Potatoes?

Raw sweet potatoes are not recommended for bearded dragons due to:

  • Harder digestibility – cooking softens the vegetable matter.
  • Higher resistance starch content – cooking gelatinizes starches for easier breakdown.
  • Potential exposure to pesticides or bacteria.
  • Raw oxalates may hinder calcium absorption more.

Light cooking via steaming, boiling, or baking breaks down carbohydrate content and makes nutrients in sweet potatoes more bioavailable for bearded dragon digestion and absorption.

How Should You Prepare Sweet Potato for Bearded Dragons?

The best ways to prepare sweet potato for bearded dragons include:

  • Steaming or boiling: Cook until soft enough to easily mash with a fork. Allow to cool before feeding.
  • Baking: Bake at 350°F for 45-60 minutes until soft. Let pieces cool before serving.
  • Mashing: After cooking, mash with a fork to make it easier for dragon tongues and throats to handle.
  • Cut appropriate sizes: Cut cooked sweet potato into small pieces your dragon can easily swallow.
  • Avoid seasoning: Do not add sugar, cinnamon, butter or other flavor additions.

What is the Best Amount of Sweet Potato to Feed Bearded Dragons?

Sweet potato should only be an occasional treat in a bearded dragon’s diet. Follow these portion guidelines:

  • Adult dragons: 1-2 small pieces 2-3 times per week.
  • Juvenile dragons: A few tiny bites 1-2 times per week.
  • Do not exceed more than 10% of total weekly diet.
  • Adjust amounts based on dragon’s weight and individual reactions.

Look for signs of loose stool or diarrhea after feeding sweet potato. If present, reduce the amount and frequency.

What Are the Best Alternatives to Sweet Potatoes for Bearded Dragons?

Some healthy alternatives to provide beneficial nutrients instead of sweet potato include:

  • Dark leafy greens – collard, mustard, turnip greens provide more calcium.
  • Winter squash – butternut, acorn squash have less sugar.
  • Bell peppers – all colors provide vitamin C and carotenoids.
  • Carrots – offer vitamin A with less sugar in moderation.
  • Sweet potatoes – provide fiber, vitamins, minerals in small amounts.

A variety of vegetables, greens, lean proteins, and limited fruit will meet all of a bearded dragon’s nutritional needs without relying on sweet potato as a staple vegetable.

Can Bearded Dragons Eat Sweet Potato Leaves?

Sweet potato leaves are edible for humans and can also be given to beardies. They provide more calcium and nutrients compared to the root. However, sweet potato leaves should still only be an occasional treat a few times a month to provide diet variety. Most beardies seem to enjoy sweet potato leaves.

Can Bearded Dragons Eat Sweet Potato Fries?

It’s best to avoid feeding bearded dragons sweet potato fries, for a few reasons:

  • High fat and salt content from frying or seasoning.
  • Potential for burns from hot fries right out of the oven.
  • Small pieces could be a choking risk.

Plain baked sweet potato without any oil or seasoning is safer and healthier for bearded dragons.

Can Bearded Dragons Eat Canned or Pureed Sweet Potatoes?

Canned or pureed sweet potatoes are not recommended for bearded dragons, for these reasons:

  • Canned varieties often have added sugar or syrup.
  • Mashing into a puree presents a choking risk from sticky consistency.
  • Pureeing breaks down fiber content needed for healthy digestion.
  • Purees can cling to the mouth making it hard to swallow and digest.

Chopping cooked sweet potato into small pieces is safer and allows the bearded dragon to get fiber benefits.


In conclusion, sweet potatoes are an excellent occasional treat for bearded dragons when provided in moderation. The optimal amount is just 1-2 small pieces, 2-3 times per week for adults and less for juveniles. Cook sweet potatoes thoroughly before feeding and accompany treats with greens, vegetables, and lean proteins for a balanced diet. Monitor stool quality and reduce sweet potato if diarrhea occurs. While providing many beneficial nutrients, too much can lead to health issues, so variety and moderation is key when adding sweet potatoes to a bearded dragon’s diet.
