Here you can find information on various supplements for your tortoise. Many of these are essential items to ensure that your tortoise remain healthy and can get all of the vitamins and minerals it needs. In captivity supplements are used to make up the difference that they are unable to obtain from their food. For example a lot of the food Hermann tortoises consume grows in calcium rich soils, however a lot of the soil that we have in the UK is not as high or as rich in calcium, so therefore the tortoises intake is less, because the food is not exposed to high levels of calcium. This is why it is important to offer calcium to tortoises.
