This calcium supplement for turtles was developed and blended from the perspective of turtle breeders. It uses three types of sterilized calcium carbonate and is blended with a perfect balance of nutritious mulberry leaf powder, mineral-rich seaweed powder, and more. (Vitamin D3 is not included.) The addition of fragrant "mulberry leaf powder" makes it easier for turtles that dislike calcium supplements to eat. We actively administer this supplement, especially to growing turtles and female breeders before and after egg-laying, as calcium deficiency is a concern. The recommended usage is approximately 3% of the food. For land turtles, wash or mist the surface of vegetables to add moisture, sprinkle this product on, and feed. It can also be used as food for crickets and worms. Capacity: 130g
