Can Iguanas Eat Grapes?

Yes, iguanas can eat grapes in moderation. Grapes are a good source of vitamins and minerals, including vitamin C, potassium, and fiber.

However, they are also high in sugar and oxalates, which can be harmful to iguanas if consumed in excess.

You may want to remove the seeds from the grapes before feeding them to your iguana, and wash the grapes thoroughly before feeding.

You can also mix grapes with other fruits and vegetables to create a healthy and nutritious salad for your iguana.

If you are going to feed grapes to your lizard, it is important to do so in moderation. Only give them a few grapes at a time, once or twice a week.

Iguanas can eat any variety of grapes. 

Green, purple, red, black, pink and yellow grapes, thompson grapes and concord grapes are all safe for bearded dragons, as long as the fruits are mature.

Seedless varieties are however recommended.

Things to Consider

  • Sugar content: Grapes are high in sugar, which can lead to weight gain and other health problems in iguanas. It is important to only feed grapes as an occasional treat.
  • Oxalates: Grapes contain oxalates, which can bind calcium and prevent its absorption. This can lead to calcium deficiency, which can be a serious health problem for iguanas.
  • Seeds: The seeds in grapes are generally to small to be a choking hazard for iguanas. Yet, you may want to remove the seeds before feeding grapes to your lizard, especially if its still a baby or juvenile. Alternatively, opt for seedless grape varieties.

Better Alternatives

If you are looking for a safe and healthy fruit to feed your iguana, there are many other options available.

  • Berries such as blueberries, raspberries, strawberries, mulberries, and blackberries are lower in sugar and oxalates compared to grapes, and they make for a tasty treat that iguanas tend to love. You may dust these with some calcium powder for a boost in much-needed minerals.
  • Other fruits like melons, mangoes, and papaya are also healthy choices for iguanas.
  • Vegetables such as collard greens, mustard greens, turnip greens, dandelion greens, kale, and broccoli are all excellent choices for iguanas. These vegetables are high in calcium and other essential nutrients.
  • Other vegetables that iguanas can eat include bell peppers, sweet potatoes, carrots, green beans, and squash.

It is important to offer iguanas a variety of fruits and vegetables to ensure that they are getting all of the nutrients they need.

It is also important to feed iguanas in moderation, as too much fruit can lead to health problems such as obesity and diarrhea.


To keep your pet iguana healthy, you should consider adding a calcium supplement without phosphorus to their diet two to four times a week.

This is because calcium is essential for strong bones, muscle function, and preventing metabolic bone disease.

You should also use a reliable reptile multivitamin once a week to provide your iguana with essential nutrients for growth, immune function, and overall health.

Remember to follow the dosage instructions and consult a reptile veterinarian for personalized guidance.
