The best vitamin A foods for pet turtles are dark leafy greens and orange or yellow vegetables, such as dandelion greens, pak choi, carrots, squash and sweet potato. Many turtles get too little vitamin A on a diet of only dried food or shrimp, so adding these vegetables (and a quality pellet) is the simplest way to prevent a deficiency.
Why Turtles Need Vitamin A
Vitamin A keeps the eyes, skin, and the lining of the nose, mouth and airways healthy. In the wild, aquatic turtles get plant carotenoids that their bodies turn into vitamin A. Captive turtles fed mostly dried turtle mix or shrimp can miss out. A shortage is called hypovitaminosis A, and it is common in young sliders, map turtles and musk turtles.
Best Vitamin A Foods for Turtles
Leafy greens
- Dandelion greens (only from areas with no pesticides)
- Pak choi and collard greens
- Broccoli leaves and florets, in moderation
- Romaine lettuce, which is lighter in nutrition, so rotate it with darker greens
- Aquatic plants such as anacharis (waterweed), which many aquatic turtles nibble
Orange and yellow vegetables
- Carrots, shredded or grated
- Winter squash
- Sweet potato, cooked and cooled
Commercial pellets
A good complete turtle pellet is a reliable base because it is formulated with vitamins added. Check the label for your turtle’s species and age. Our review of Mazuri turtle pellets is a good place to start.
Foods That Are Poor Sources
Shrimp and many dried turtle mixes are low in vitamin A when fed alone. Iceberg lettuce adds water but little nutrition. Fruit has sugar and should be an occasional treat, not a vitamin A source.
Signs of Low Vitamin A
Watch for these signs:
- Swollen, puffy or closed eyes
- Poor appetite and weight loss
- Dull, lethargic behavior
- Dry or peeling skin
- Runny nose or breathing trouble
If you see any of these, see a reptile vet promptly. Deficiency often comes with infections that need professional treatment.
Do Not Over-Supplement
Do not give vitamin A supplements, drops or injections on your own. Too much vitamin A can also harm a reptile, and the right amount depends on the animal. Only add a supplement if your vet recommends it and tells you how to use it.
Feeding Tips
- Wash all produce well and chop it small.
- Offer vegetables several times a week, and increase the share as your turtle matures. Species differ, so check care guidance for yours.
- Remove uneaten fresh food from the water so it does not foul the tank.
- Rotate foods to cover more nutrients.

Bottom Line
Feed a quality pellet plus a regular rotation of dark leafy greens and orange vegetables, and skip a diet of dried food or shrimp alone. If your turtle has swollen eyes or stops eating, call a reptile vet instead of treating it at home.
