Most experts advise against giving desert tortoises fruits as these can be toxic; however, in moderation they provide vital Vitamin C which all species of tortoise need for optimal health.
Oranges contain high concentrations of Vitamin A, an essential nutrient for tortoises that cannot synthesize it themselves. Plus, their ideal ratio of calcium-phosphorus content provides optimal care.

Oranges are a good source of vitamin A
Oranges provide both vitamin A and calcium. Tortoises must consume enough calcium in their diet in order to prevent osteoporosis; female tortoises will lay eggs shortly; cuttlebones are an easy way to add additional calcium; you can find these available at pet stores’ bird department and are composed of the hard internal shell of a cuttlefish.
All tortoises require access to clean, fresh water daily in order to hydrate themselves and eliminate toxins from their bodies. Although it may seem as though tortoises do not require much water, this misconception should not be believed; fresh, clean water is vitally important.
Tortoises need a varied diet in order to remain healthy. Their daily needs should include fiber-rich foods like hay and grass, leafy greens, vegetables, weeds flowers and fruits (when fed in moderation) that comprise their bulk of food requirements.
They are a good source of vitamin C
Tortoises should consume natural grass hay such as alfalfa, leafy green vegetables, weeds and flowers as well as moderate quantities of fruit [in moderation]. Tortoises also require ample Vitamin C from various sources – oranges provide one convenient source.
But take caution when giving your tortoise oranges, as their excessive intake could be harmful to its health. Citrus acid and sugar both present serious threats; only give these treats on special occasions or as special treats.
Along with oranges, cuttlebones are another great source of calcium for your tortoise. Composed of natural calcium carbonate material (aragonite), these bones can be found in bird department of pet stores. While some may smell fishy to some tortoises, soaking or leaving outside in sun/rain/sprinklers for several days may make these more palatable to them.
They are a good source of calcium
Tortoises’ diet should consist of grass, vegetables, alfalfa hay, leafy greens, flowers, weeds and fruits (in moderation). Their calcium needs can be met through eating plants grown in soil rich with calcium; or supplemented by feeding on snail shells or cuttlebones from other animals.
Calcium deficiency in tortoises can be fatal. This results in metabolic bone disorder which leads to softening of bones and paralysis; caused by an imbalance between calcium and phosphorous content of their food source.
Sticky Tongue Farms suggests supplementing a tortoise’s diet with a calcium and mineral mix with a 2:1 calcium to phosphorous ratio; they recommend their Miner-All reptile calcium & mineral supplement at every feeding for babies, half growns, egg laying females, as well as every other feeding for egg layers. In addition, this product contains high levels of Vitamin A & C essential for immune health support.
They are a good source of fiber
A tortoise’s diet should be high in fiber to soften their stools and reduce wear on their beak at the front of their mouth, as well as to get adequate amounts of essential nutrients that support overall health. A diet rich in variety also ensures they get all of their daily requirements.
Oranges provide fiber, vitamin C and calcium; however, their high sugar and acidity levels can wreak havoc with digestive systems; furthermore, this sugar could disrupt tortoise’s gut microflora.
Ideal, only offer your tortoise oranges that you have grown yourself as supermarket fruits are often covered in pesticides which could make him sick. Also avoid citrus fruits if he’s sensitive; offer leafy greens and weeds instead that are suitable. Alternatively you could provide succulents like Opuntia or prickly pear cacti as succulents as an alternative source.
