In their natural habitat, they wake up and bask in just a few hours before sunrise. But this time is enough for leopard gecko absorbing all the UV light that they will need.
In the enclosure, there are many synthetic supplements that can help your geckos get vitamin D3. These supplements play the role of UVB light, which helps a leopard maintain healthy bones, skin and improve immune systems.
