What Types of Substrates Are Recommended For Bearded Dragons?

Substrate is the term used for the “bedding” inside a reptile’s habitat. Opinions of the most ideal substrate for bearded dragons vary widely by keepers and professionals in the reptile hobby.

This article will break down the most popular substrate options for bearded dragons!

a solid substrate is a great substrate option for a bearded dragon enclosure. The Zen Mat from Zen Habitats is a great solid substrate option for bearded dragons

Solid Substrates:

Solid substrates are bedding materials that are solid, meaning they cannot be dug into. Some common choices for solid substrate include:

Slate Tile
Zen Mat
Newspaper
Paper Towels

Pros for solid substrate:

Easy to clean
Eliminates risk of eating loose substrate (which, in rare cases, can cause impaction)
Not as heavy for enclosures that cannot support very much weight

Cons for solid substrate:

Doesn’t provide natural digging opportunities.
Some options can be hard on bearded dragons limbs over time and cause slipping from lack of traction

Loose Substrates:

A loose substrate is any sort of bedding that is made up of “loose” materials like dirt or sand. Some common loose substrate options include:

Commercially available sand and soil mixes
Super fine quartz sand
Bioactive mixes
Excavator clay

Pros for loose substrate:

Provides natural digging opportunities
Aids in thermoregulation
Less maintenance (bioactive setups)
Can sustain plant life for bioactive enclosures

Cons for loose substrate:

More expensive up front
Can be messier
Increased risk of impaction from eating substrate**

** Studies have determined that the loose substrate alone does not often cause impaction, but multiple factors along with the use of loose substrate including:
Incorrect loose substrate material (calcium sand, walnut shell)
Dehydration
Low basking temperatures
High parasite loads in the gut
Metabolic bone disease

Bioactive vs. Loose Substrate – What's The Difference?

Bioactive substrates are one possibility when using loose substrate. A bioactive substrate can support the growth of plants, microflora, and microfauna.

Substrate options that are not recommended:

Some solid and loose substrates, even though are commercially available, are not appropriate for bearded dragons. Please see the attached list and reasons why:

Reptile carpet: Harbors bacterial growth and can catch reptile toenails in the fibrous material.
Calcium or Vitamin sand: These are dusty which can cause eye and respiratory irritation. They also have an increased risk of impaction due to the calcium carbonate which forms hard clumps when wet. Calcium carbonate can also neutralize stomach acid which can lead to digestive complications if swallowed.
Ground nut shells: Very dusty which can irritate the eyes and lungs if inhaled. Particles are very sharp and can cause eye injuries and issues in the digestive tract if accidentally consumed. Clumps firmly when wet and therefore can lead to impaction if ingested.
Wood products (mulch, bark, shavings): Can lead to impaction if ingested.
Linoleum/Shelf liner: Many of products release VOCs which can be harmful to breathe in.

Substrate for baby (juvenile) bearded dragons:

Bearded dragons explore their worlds by taste, and hatchlings are no exception. Hatchling bearded dragons will lick and taste everything in their enclosure, for this reason, a loose substrate may not be appropriate for young beardies. We prefer to use a solid substrate for baby dragons such as our Zen Mat, newspapers, or paper towels.

Substrate for sick bearded dragons:

Whether your bearded dragon is acutely sick with an illness or infection, has a chronic medical condition like MBD (metabolic bone disease), or is recovering from a procedure like surgery, using a solid substrate can help make your life much easier.

If your beardie is sick, it is best to use a substrate that can be disposed of or easily sanitized. It is impossible to keep loose substrate as clean and free of pathogens which is why a solid substrate is recommended for hospital and quarantine setups.

Some special needs dragons may not have full mobility and can struggle with a loose substrate, for these beardies a product like the Zen Mat can be very helpful. The Zen Mat holds onto heat well and has a cushioned and textured surface which is easy on your animal’s joints and prevents slipping and sliding around while walking.
