Most tortoises are herbivores, but the balance of grasses, hay, leafy greens, flowers, vegetables, formulated food, and supplements varies. Ask a reptile-knowledgeable veterinarian to confirm a diet for your tortoise before treating any general feeding guide as a recipe.
Start by identifying your tortoise
Diet recommendations are not interchangeable across tortoises. The University of Illinois College of Veterinary Medicine names red-footed, sulcata, Hermann’s, Russian, and Greek tortoises among common pet species and advises that what they eat depends on the species. Its general overview says tortoises are herbivores and may eat grasses, hay, greens, and flowers, but it does not prescribe one menu for all of them.

Dr. Amanda Wong, a veterinarian completing a three-year residency in zoological companion animal medicine and surgery at Illinois, puts the priority plainly: “Species-appropriate diet is crucial for having a healthy tortoise.” If you are unsure of your tortoise’s species or life stage, confirm it with a reptile veterinarian before building a feeding plan.

Forage—such as grasses, hay, weeds, and suitable leafy plants—is central in the veterinary guidance, but which plants and proportions suit your pet depend on its species. A concrete percentage is available for desert tortoises specifically, not as a universal tortoise formula.
#1 Best Overall
- High fiber level and Low Starch - Grass hay based diet.
- Contains vitamins A and vitamin E - For eye and skin health.
- Contains live probiotics - Helps support gastrointestinal health.
- No artificial colors.
- Best for arid-zone and grassland herbivorous tortoises and lizards such as the Aldabra, African Spurred/Sulcata, Desert, Egyptian, Galapagos, Gopher, Greek, Leopard, Pancake, Radiated or Yellow-Footed tortoise, as well as Chuckwalla and Uromastyx lizards.
Desert tortoises: a forage-heavy example
The University of California, Davis School of Veterinary Medicine’s 2019 desert-tortoise guidance describes a high-fiber, moderate-protein, low-fat, calcium-rich diet. It gives this split: 85% grasses, weeds, and dark leafy greens, and 15% hard vegetables. It also says dark greens should make up no more than half of the forage.
Examples of forage named on that desert-tortoise page include alfalfa hay, Bermuda grass, clover, mallow, Opuntia cactus pads and flowers, rye grass, rice grass, and sowthistle. Its suggested dark greens include collards, dandelion greens and flowers, escarole, endive, grape leaves, mustard greens, turnip greens, and watercress. These examples and proportions belong to that desert-tortoise guidance; do not assume they apply to a Russian, sulcata, or other tortoise without species-specific confirmation.
Rank #2
- Irresistible Formula: Crafted to appeal to land turtles and tortoises, making every meal enjoyable.
- Balanced Nutrition: Provides a perfectly balanced diet for tortoises of all sizes and species.
- Supports Shell Health: Enriched with calcium, Vitamin C, and B12 to promote strong and healthy shell development.
- Essential Nutrients: Packed with proteins and vitamins needed for optimal growth and overall health.
- Vitamin-Enriched Pellets: Fortified pellets ensure your pet receives a complete and nutritious meal.
Other species: avoid borrowing a percentage
For non-desert species, the Illinois guidance supports a species-dependent mix of grasses, hay, greens, and flowers, but does not give one percentage breakdown. The safest practical approach is to use a reptile veterinarian’s plan for the identified species rather than transplanting the desert-tortoise ratio or assembling a diet from a broad reptile shopping list.

For the 15% vegetable share in its desert-tortoise example, UC Davis lists squash, bell peppers, carrots, green beans, peas, pumpkin, sweet potatoes, and turnips. That page also identifies some foods as occasional treats and specifically says not to feed lettuce. These cautions are for its desert-tortoise guidance, not automatically a complete avoid-or-feed list for every tortoise species.
Rank #3
- Formulated for Russian, Greek, Sulcata, Leopard and Pancake Tortoises.
- Added vitamins and minerals
- No artificial colors or preservatives
Context matters: UC Davis’s general herbivorous-reptile shopping guide lists lettuce, while its desert-tortoise page says not to feed lettuce. The broader guide also says fruit should make up about 5% of a pet reptile’s diet and names apples, grapes, and bananas as examples. That 2019 figure is broad herbivorous-reptile guidance, not an established target for every tortoise; do not combine it with the desert-tortoise 85/15 split as if the numbers formed one diet formula.

Consider formulated food only as a species-appropriate option
Commercial pellets are available, but their existence does not make them interchangeable or establish a complete diet for every tortoise. Illinois advises owners to check ingredients for suitability to the individual species. Wong says: “There are a variety of pelleted diets available commercially, and owners should investigate the ingredient list to ensure it is appropriate for their individual tortoise species.”
Rank #4
- Best Fed To: Mazuri Tortoise food is best for tropical and omnivorous tortoises, such as the Burmese or Indian Star Tortoise, Elongated Tortoise, Red-footed Tortoise, Adult Box Turtles and Wood Turtles.
- Great taste & highly palatable, large particle. Great nutrition for your tortoise.
- Great for tropical and forest tortoises. Moderate protein and energy to meet the needs of omnivorous species
- Watch your pet thrive with wholesome nutrition. Plus, this tortoise feed contains no added colors or artificial flavors.
- Antioxidants, vitamin E, and vitamin A. To help support the immune system and eye health.
The California Veterinary Emergency Team’s January 2025 feeding guide gives a broad size-based example: it lists Mazuri Tortoise Chow with dark leafy greens for small tortoises under 10 kg, and grass, oat, or timothy hay for giant tortoises over 10 kg. This is that guide’s example, not a universal recommendation or evidence that the product is complete or ideal for every species. Check suitability with a reptile veterinarian before relying on a formulated food. California Veterinary Emergency Team: Avian, Small Mammal, and Exotics Feeding Guide

Supplement advice differs between the cited guides. UC Davis’s desert-tortoise page recommends calcium carbonate powder sprinkled on moistened food daily and a weekly vitamin supplement. CVET’s broader guide describes calcium supplementation once or twice weekly for tortoises. Because those instructions differ in scope and frequency, neither should be treated as a schedule for every pet tortoise. Have a reptile veterinarian specify the supplement, amount, and frequency for your animal and its setup.

A practical way to shop for tortoise food
- Confirm the species and life stage. Ask a reptile-knowledgeable veterinarian to identify your tortoise and recommend an appropriate diet.
- Prioritize the forage that fits that species. Use the veterinarian’s guidance to choose suitable grasses, hay, greens, and flowers; do not apply the desert-tortoise 85/15 ratio to another species by default.
- Check every broad food list against species-specific advice. A food appearing in a general herbivorous-reptile guide does not necessarily belong in your tortoise’s diet.
- Inspect formulated-food ingredients. Treat a product example such as Mazuri Tortoise Chow as an option to discuss—not a universal staple—and check whether it suits your tortoise.
- Get a supplement schedule tailored to your animal. Ask which supplements to use and how often rather than combining schedules from different guides.
