How to Gut-Load Mealworms for Leopard Geckos?

Proper nutrition is crucial for the health and well-being of your leopard gecko. One important aspect of providing adequate nutrition is gut-loading, which involves feeding mealworms a variety of nutrient-rich foods 24-48 hours before offering them to your gecko.

Without gut-loading, your gecko may suffer from health issues and have a shorter lifespan.

Leopard geckos require a diverse diet of feeder insects to obtain the necessary nutrients. These insects feed on a range of plants, fruits, and vegetables, which provide essential vitamins and minerals that leopard geckos cannot obtain directly from vegetables.

Gut-loading mealworms should be a regular part of your leopard gecko’s diet. It’s important to source your mealworms from a reputable source and rinse them lightly before storing them to remove any debris, dirt, or pesticide contamination.

You can gut-load your mealworms with base foods such as oatmeal, cereal, pumpkins, squash, and potatoes/sweet potatoes or fruits such as apples or other vegetables 24 hours before feeding them to your leopard gecko.

By incorporating gut-loading into your leopard gecko’s diet, you can ensure they receive all the essential nutrients they need for optimal health and longevity

What Is The Importance Of Gut-Loading Mealworms?

Gut-loading mealworms is an important aspect of feeding leopard geckos because it ensures that the insects are providing the necessary micro-nutrients that the leopard gecko needs in their diet.

By feeding mealworms a variety of nutrient-rich foods 24-48 hours before offering them to the leopard gecko, the mealworms will transfer those nutrients to the gecko when they are consumed.

Without proper gut-loading, the mealworms may not provide all the necessary nutrients, leading to health issues and a shorter lifespan for the leopard gecko.

Do You Have To Gut-Load Mealworms?

Mealworms are nutritiously dense and don’t need to be gut-loaded. However, providing healthy, nutrient-rich foods every other day and at least two days before you feed them to your leopard gecko is essential. It will ensure your gecko gets all the crucial nutrients it needs to be healthy and live better.

How Often Should You Gut-Load Mealworms?

There is no limit to how often you can gut-load your mealworms. You can do it once a week or a few days. These will depend on you and your leopard geckos’ preference.

Should All Feeder Insects Be Gut-Loaded?

No. Not all feeder insects must be gut-loaded before feeding them to your leopard gecko. However, you should ensure that all your geckos’ main diets are fed foods rich in nutrients.

Examples include dubia roaches, mealworms, and crickets. Other bugs like black soldier flies, hornworms, and silkworms feed on specific diets; therefore, research what foods you should provide them.


Mealworms are nutritiously dense and don’t need to be gut-loaded. However, gut-loading provides added minerals and vitamins to your mealworms which will be passed on eventually to your leopard gecko. You can gut-load your mealworms 2 hours to 48 hours before feeding them to your gecko.
