Green Iguana Society logo  1999-2001, D. Baze




Anyone who has ever been in a pet store, shopping for your iguana on-line, or looking through a herp magazine has probably noticed the large variety of commercial iguana foods. These foods are available in packages of dry, frozen, and other forms. There are many different brands as well, many of which claim to be a "complete diet" for iguanas. The Green Iguana Society does not recommend using these types of food as a main part of an iguana's diet. If used at all, they should only be used as an occasional source of supplemental protein.

Although too much protein (such as is found in animal products) is harmful to iguanas, they still need adequate amounts of protein in their diets. Many vegetables are low in protein, and it may be difficult to provide your iguana with enough protein while still avoiding animal products. If additional protein is needed, you may want to consider the occasional addition of commercial food in your iguana's diet. Commercial foods can also be convenient when you are away and a pet-sitter is taking care of your iguana for you. It is important to note, however, that commercial iguana foods can be very expensive and often contain unhealthy ingredients. As a result, commercial foods must be chosen carefully and used wisely. Providing supplemental protein in other ways can be more economical for you, as well as healthier for your iguana. For more information on supplemental protein, please visit our Vitamins & Supplements page.

Below is a list of many of the most popular commercial iguana foods. Many of the companies that sell these foods will state that they are a well-balanced and complete diet. However, many of these foods contain animal protein and/or other harmful ingredients. To help you chose the commercial food that is right for you to use occasionally, we have gathered nutritional information on various foods. Below you will find information on the main ingredients of each food, along with the percent protein, fiber, fat and moisture content. We have also provided comments based on that information, which we hope will help you decide on which, if any, commercial foods to use in your iguana's diet.

Please note that dry pelleted food should be soaked in water prior to being offered to your iguana. This will help prevent your iguana from becoming dehydrated.

Walkabout Farm Iguana Growth Mix -
Ingredients Information:
The first ingredient listed is clover. The next several ingredients are blossoms from various types of plants. The ingredients also include carrot, egg and kelp.
Nutritional information:
17% protein (min), 18% fiber (min), 3% fat (max), 11% moisture (max)
Comments:
Of all the prepared commercial foods available, this is by far the best at this time. The ingredients include many good plant foods, and no artificial flavors, colors or fillers. Although eggs are not a recommended food for green iguanas, the egg in this formula is a dried egg product from which the fat has been removed. It has also been screened for Salmonella. Walkabout makes several different formulas of iguana foods. Visit their website at http://www.herpnutrition.com for more information.

ZooMed Soft-moist -
Ingredients Information:
These formulas have alfalfa as the #1 ingredient, and also contain lima beans, collard and mustard greens, and kale. In addition, they contain no artificial colors or flavors.
Nutritional information:
Adult formula: 14% protein (min), 18% fiber (min), 4% fat (min), 14% moisture (max)
Juvenile Formula: 24% protein (min), 14% fiber (max), 6% fat (min), 14% moisture (max)
Comments:
The lack of artificial colors and flavors is a plus, the use of alfalfa and dried greens is desirable, and the fiber content is good.

Rep-Cal Iguana Food -
Ingredients Information:
Main ingredients include corn, soybean, and wheat. Apple, dried fruit and artificial color are also listed.
Nutritional information:
Adult: 16% protein (min), 18% fiber (max), 1% fat (min), 12% moisture (max)
Juvenile: 24% protein (min), 16% fiber (max), 1% fat (min), 12% moisture (max)
Comments:
Although this food has corn for a main ingredient, and also contains artificial colors, the protein and fiber contents are good, and the inclusion of apple and other dried fruits make this an acceptable choice for occasional use. This food comes highly recommended by many iguana owners. Iguanas that are hesitant to eat due to illness will often readily accept Rep-Cal.

Flukers Blue Diamond Formula-
Ingredients Information:
Alfalfa is the #1 ingredient, followed by oats and corn. There are no artificial colors or flavors added.
Nutritional information:
12% protein (min), 18% fiber (max), 2.5% fat (min), 12% moisture (max)
Comments:
Of the two Flukers formulas, this is a better choice due to its use of alfalfa as a main ingredient and its lack of artificial colors and flavors. In addition, the protein and fiber content is high. This formula is acceptable for occasional use.

Mazuri Iguana Diet -
Ingredients Information:
The first few ingredients include soybean meal, alfalfa meal, wheat and corn. There are no artificial colors or flavors listed, and no animal products in the ingredients.
Nutritional information:
25% protein (min), 18% fiber (max), 2.5% fat (max)
Comments:
Although this diet lacks some of the more attractive ingredients, such as dried greens and vegetables, it does contain alfalfa as a main ingredient. This food contains high amounts of protein and fiber, which make it attractive. The lack of artificial flavors and colors is another plus. This is a decent choice for occasional use.

ESU Reptile Nutrigrow Juvenile/Breeder Formula -
Ingredients Information:
The three main ingredients listed are soybeans, corn and alfalfa.
Nutritional information:
25% protein (min), 14% fiber (max), 2% fat (min), 12% moisture (max)
Comments:
Although the ingredients lack more desirable foods like dried greens and vegetables, this diet lacks artificial colors and flavors, and has good protein and fiber content. Not a bad choice for occasional use.

ESU Reptile Adult/Maintenance Formula -
Ingredients Information:
Alfalfa, corn, soybeans and wheat germ are the first few ingredients listed.
Nutritional information:
18% protein (min), 16% fiber (max), 2.5% fat (min), 12% moisture (max)
Comments:
Protein and fiber content is good, and the lack of artificial colors and flavors are a plus. The use of alfalfa as the main ingredient is another good point. Not a bad choice for occasional use.

Tetra Reed's Iguana Food -
Ingredients Information:
The order of ingredients in the adult and juvenile formulas vary slightly, but both contain alfalfa meal as a major ingredient, along with wheat, corn and oats. Other ingredients include molasses and "color enhancers".
Nutritional information:
Adult: 14% protein (min), 15% fiber (max), 3% fat (min), 13% moisture (max)
Juvenile: 20% protein (min), 15% fiber (max), 4% fat (min), 13% moisture (max)
Comments:
These formulas may not be too bad, but the inclusion of molasses and suspicious "color enhancers" cause this diet to lose points. This food is not highly recommended.

Brown's Zoo-Vital Iguana Foods - Juvenile Formula -
Ingredients Information:
Corn, wheat, oats, soybean, and alfalfa leaf are the first few listed. Further down the list is assorted dried fruit, and dried bacterial cultures.
Nutritional information:
15.5% protein (max), 6% fiber (max), 4.5% fat (min), 12% moisture (max)
Comments:
This food has a decent amount of protein, but is lacking in the fiber department. The ingredients are mostly fillers, although the addition of dried fruit and bacterial cultures, which may aid in digestion, are a plus. While not the worst choice, this brand is not among the best, either.

Flukers Fruit Formula -
Ingredients Information:
The main ingredients are corn and oats. Artificial colors and flavors have been added.
Nutritional information:
Adult: 12% protein (min), 9% fiber (max), 3% fat (min), 10% moisture (max)
Juvenile: 18% protein (min), 6% fiber (max), 5% fat (min), 10% moisture (max)
Comments:
Even though this is "Fruit Formula" it contains no fruit. The ingredients leave something to be desired, and the fiber content is not that high. This food is not a good choice.

ZooMed Canned Food -
Ingredients Information:
These formulas have corn as the #1 ingredient, and also contain artificial colors and flavors.
Nutritional information:
Adult: 1.2% protein (min), 1% fiber (max), 0.5% fat (min), 78% moisture (max)
Juvenile: 2.4% protein (min), 1% fiber (max), 0.5% fat (min), 78% moisture (max)
Comments:
Although a moist formula may seem desirable due to its water content, this brand is not recommended. The #1 ingredient is corn, which is more of a filler than a nutritive substance. The addition of artificial colors and flavors is another strike against this formula. The lack of protein, and, more importantly fiber, is another reason to avoid using this food.

Pretty Pets Fruit Flavored Iguana Food -
Ingredients Information:
The first ingredient listed in this formula is corn, followed by oats, corn gluten, beet pulp and potato meal. This diet also contains coconut oil and artificial colors.
Nutritional information:
Adult: 12% protein (min), 9% fiber (max), 3% fat (min), 10% moisture (max)
Juvenile: 18% protein (min), 6% fiber (max), 5% fat (min), 10% moisture (max)
Comments:
The ingredients in this formula leave something to be desired - the top ingredients are not the best iguana foods, and the addition of coconut oil, which is highly saturated, and artificial colors, make this diet a poor choice.

Kaytee Reptile Fortified Diets -
Ingredients Information:
The main ingredients of this formula are corn, oats and wheat, although alfalfa is also listed. This diet also contains artificial colors and molasses. On the positive side, the ingredients also include sunflower petals, rose petals, strawberries and yucca, although they are down on the list, and presumably are present in small amounts. The juvenile formula includes fish meal - an animal product and a big no-no.
Nutritional information:
Adult: 12.5% protein (min), 12% fiber (max), 3% fat (min), 12% moisture (max)
Juvenile: 19% protein (min), 10% fiber (max), 3% fat (min), 12% moisture (max)
Comments:
Although the inclusion of flower petals and yucca make this formula somewhat attractive, the use of molasses, artificial colors and fish meal (in the juvenile formula) definitely make this one worth avoiding.

Animal Farms LM Tropical Magic -
Ingredients Information:
Wheat, oats, corn, and alfalfa are the main ingredients. Included in the ingredients are artificial flavors and colors, and dried Musca domestica larvae (housefly maggots).
Nutritional information:
Adult: 12.5% protein (min), 14% fiber (max), 3% fat (min), 12% moisture (max)
Juvenile: 20% protein (min), 14% fiber (max), 3% fat (min), 12% moisture (max)
Comments:
Although this formula has decent amounts of protein and fiber, the inclusion of artificial colors and flavors and larvae in the ingredients make this a poor choice. Not recommended.

T-Rex Fruit/Flower Formula and Vegi Formula -
Ingredients Information:
Interestingly, these two formulas contain the exact same ingredients. Corn is listed as the #1 ingredient, followed by wheat, oat, animal fat, coconut fat, artificial flavors and colors. On the positive side, these two formulas do contain hibiscus.
Nutritional information:
Adult: 14% protein (min), 7% fiber (max), 3% fat (min), 10% moisture (max)
Juvenile: 19% protein (min), 6% fiber (max), 5% fat (min), 10% moisture (max)
Comments:
The inclusion of animal fat and highly saturated coconut fats, as well as artificial colors and flavors make these formulas undesirable. There is also a lack of fiber. Not recommended.

Hartz Iguana Food -
Ingredients Information:
Both the adult and the juvenile formula contain the same basic ingredients - wheat, oat groats, corn, alfalfa and, among other things, ground Musca larvae. Both formulas also contain many artificial colors and flavors.
Nutritional information:
Adult: 12.5% protein (min), 14% fiber (max), 3% fat (min), 12% moisture (max)
Juvenile: 20% protein (min), 14% fiber (max), 3% fat (min), 12% moisture (max)
Comments:
This food is not recommended. In addition to using a lot of fillers, it includes harmful ingredients like the larvae (an animal product not appropriate for herbivorous iguanas) and all the artificial flavors and colors.

ZuPreem Iguana Canned Diet -
Ingredients Information:
The first ingredient listed on this diet is water, followed by corn. Also listed fairly high up on the list is meat and bone meal.
Nutritional information:
5% protein (min), 0.5% fat (min), 3.5% fiber (max), 78% moisture (max)
Comments:
While the moisture content of this food makes it somewhat attractive, this diet is not recommended due to its inclusion of meat meal, and its relative lack of protein and fiber.

Tetra Tetrafauna Land Turtle, Tortoise and Iguana Food -
Ingredients Information:
One of the first ingredients listed is dried apple, followed by soybean meal, corn meal, sugar, and dried beef liver meal. This diet also contains artificial colors and flavors.
Nutritional information:
6% protein (min), 4% fiber (max), 0.2% fat (min), 78% moisture (max)
Comments:
Any food that claims it is nutritionally complete for animals as different as omnivorous land turtles and herbivorous tortoises and iguanas raises immediate warning flags. Not only does this formula include sugar and artificial colors and flavors, which are inappropriate for any animal, but it also contains beef liver meal, which is inappropriate for vegetarian iguanas. This food also lacks protein and fiber, and is not recommended.
